Installation and Configuration

Installation

This tutorial will show you how to successfully install and configure Plesk Extended For WHMCS.

We will guide you step by step through the whole installation and configuration process.

1. Log in to our client area and download the module.
PE3 1.png
2. In the downloaded file you will find two packages that support different PHP versions.
As presented on the screen below, the first one is dedicated to PHP 5.6 up to PHP 7.0, while the second one is aimed at PHP 7.1 up to PHP 7.2.
It does not apply to open source versions.

Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.

PHP56 72.png
3. Extract the downloaded file and choose the one with the right PHP version. Upload and extract the PHP file into the main WHMCS directory.

The content of the PHP version files should look like this.

PE3 2 3.png
4. When you install Plesk Extended For WHMCS for the first time you have to rename the 'license_RENAME.php' file.

The file is located in 'modules/servers/pleskExtended/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

PE3 3.png
5. In order to configure your license key, you have to edit the previously renamed 'license.php' file.

Enter your license key between the quotation marks as presented on the following screen. You can find your license key in our client area → 'My Products'.

PE3 4.png
6. In the next step, set up the 'storage' folder as recursively writable.

This folder is available at two locations:

  1. your_whmcs/modules/addons/PleskExtended/
  2. your_whmcs/modules/servers/PleskExtended/
PE3 5.png

Activation of Addon

7. Now, you have to activate the module in your WHMCS system.

Log in to your WHMCS admin area. Click 'Setup' and then choose 'Addon Modules'.
Afterward, find 'Plesk Extended Center' and press the 'Activate' button.

PE3 6 1.png
8. In the next step you need to permit access to this module.

To do so, press 'Configure'. Next, select the required administrator roles and press 'Save Changes' .

PE3 6 2.png
9. Congratulations, you have just successfully installed Plesk Extended For WHMCS!

Configuration of Server

10. Now, we will show you how to configure a new server.

To do so, log in to your WHMCS. Go to 'Setup' → 'Products/Services' → 'Servers'. Afterward, press 'Add New Server'.

PE2 8.png
11. Next, enter your server name, hostname/IP address, username and password. Choose 'PleskExtended' from the dropdown menu and press 'Save Changes'.

Here you can also provide other server details like nameservers or maximum number of accounts. Finally, click 'Test Connection' to check if the provided credentials are valid.

Important: Due to changes in the original WHMCS Plesk module, it may be required to additionally enter the IP address into the Hostname field even if you have already provided it in the IP Address field below.
Otherwise, the "Could not resolve host" error may occur.

PE2 9.png
12. After you have configured your server correctly, you will see the following screen.

Now, you need to create a new group for your server. For that purpose, press 'Create New Group'.

PE2 10.png
13. Enter a name, click on your previously created server, press 'Add' , then 'Save Changes'.
PE2 11.png

Configuration of Product

14. In order to create and configure the product, move to 'Setup' → 'Products/Services' → 'Products/Services'.

If you do not have a product group, choose 'Create a New Group'.

PE2 12.png
15. Enter a product group name and press 'Save Changes'.
PE2 13.png
16. Once you have a product group, you can create your product and assign it to Plesk Extended.

To create a product, press 'Create a New Product'.

PE2 14.png
17. Afterward, choose your product type and the product group from the dropdown menus, enter your product name and press 'Save Changes'.

Please note that you may choose only between 'Hosting Account' and 'Reseller Account' as the product type since only those are supported by the Plesk module.

PE2 15.png
18. Now, move to the 'Module Settings' section, choose both 'PleskExtended' and your previously created server group from the dropdown menus.

Remember to add your 'Client Template Name' or 'Service Plan Name'. Plesk Extended will not work properly without a specified plan name.
Decide in what way Plesk will assign IP addresses during the accounts creation process, by choosing the appropriate method from the 'IP Address Types' dropdown list.
Here you may also enable the 'Power User' view. Do not forget to press 'Save Changes' .

PE2 16.png
19. Good job! You have just correctly created and customized your new product. It will now appear in Plesk Extended Center admin area.

Configuration of Addon

20. After you have correctly created and customized a new product, it is time to configure it.

Go to 'Addons' 'Plesk Extended' in your WHMCS.
You will find there a dashboard with a short guide on how to start using your module.
This section also offers precise data on available products and servers:

  • See the number of active/suspended/terminated accounts
  • See the list of configured Plesk products and servers
  • Go directly to the product and server configuration
  • Log in to Plesk panel from server configuration with one click
  • Easily upgrade the already configured Plesk product to Plesk Extended

21. Proceed to the 'Features' section and find the product you are interested in. Press the 'Configuration' button next to the product.
PE3 18.png
22. You will find here boxes dedicated to 'Features' and 'Applications'.

To show you an example, we will set the configuration from the very beginning, without using other configuration options of the product.

Select the features you would like to activate for your customers.

PE3 19.png
23. Next, toggle 'Install Application' that will be used to install applications by your clients.

In the 'Autoinstaller Type' field you will be free to choose between 'Installatron' , 'Softaculus' and 'Default' auto installers.

PE3 20.png
24. You may also enable the option for automatic installation of selected applications once an order is created.

Use the 'Autoinstall On Create' toggle and select the default option from the 'Apps / Configurable Options' list.

You can also choose the desired language of applications by typing in its two-letter code in the 'Language' field. A complete list of language codes can be found here.
If the field is left blank, a default value, which is 'en' (English) will be used.

Moreover, you can permit your clients to toggle automatic backups for application updates or enable them for the first application after the initial order.

Note: You can also create a configurable option with an app to be installed. You can find the instruction on how to do that here.

PE3 20 0.png
25. You can let your clients decide about the automatic application installation during ordering process by using the 'Use Configurable Options' switch and choosing the appropriate option from the list.
PE3 20 02.png
By selecting this option, you will notice a download button next to the dropdown list on the product's features list.

Its purpose is to download the available application list in the text format that can be then used for configurable options.

More information about the available configurable options and custom fields can be found here.

PE3 20 01.png
26. If you already have another product configured, you may copy its configuration.

Find the 'Copy' button on the list with products or select multiple item at once.
Then, choose the product configuration whose settings you wish to copy into the selected products.

PE3 20 03.png
27. In the next step, move to 'Server Configuration' to set up a connection.

Press the ' Configuration' button next to a desired server.

PE3 20 1.png
Enter the proper domain and IP address to allow a connection with Plesk panel and Webmail accordingly.
Do not forget to 'Save' changes once you are finished!
PE3 20 2.png
28. From now on, all your clients who ordered a previously created product will be able to manage their Plesk accounts via your WHMCS system.

Here is the summary of the ordered product in admin area. The available actions include:

  • Log In To Control Panel
  • Use Module Commands: 'Create', 'Suspend', 'Unsuspend', 'Terminate', 'Change Package' and 'Change Password'.

Upgrade Plesk to Plesk Extended Product

Once you have already configured the standard Plesk products, you can easily upgrade them to the Plesk Extended products.

Note: Before you start, make sure that you have already configured the Plesk Extended server.
To start, proceed to the 'Dashboard' in the Plesk Extended addon. Next, find your standard Plesk product on the list and press the 'Upgrade Product' button.

PE3 24 0.png
Now, select the new server group configured for the Plesk Extended module.

Note: Make sure that this server configuration is exactly the same as the standard cPanel server configuration.
Press 'Confirm' to proceed with the product upgrade. After completion, the product will switch its module settings to the ones from the Plesk Extended module and server.

PE3 24 1.png

Management

Plesk Extended allows your customers to manage their accounts via client area in your WHMCS system.

In this short guide we will present you with the management possibilities of our module.

Client Area

Addon Domains

Addon domains section allows you to link the domain to a subdirectory of your account.
You can view and manage addon domains, edit document root and make redirections.

Note: Make sure this feature is enabled for your account before using

PE3 28.png
Press the 'Create Addon Domain' button and enter the desired details.
Please note that an FTP account will not be automatically created with the domain.
PE3 28 1.png

Applications

Install your favorite applications in a few seconds without even accessing Plesk.

Use Plesk Extended For WHMCS to:

  • Install applications
  • Edit/delete applications
  • Create and restore backups

To start, simply proceed to 'Applications' , and then find the 'Install New' section.

PE3 31.png
Afterwards, you will see an extensive menu with application categories.
For presentation purposes we will install 'PrestaShop' located in the 'E-Commerce And Business' category. Find 'PrestaShop' and click on it.
PE3 32.png
Now, you have to enter necessary installation details and then press 'Install Application' to follow. Wait for the 'Success' notification.
PE3 33.png
View the list of your installed applications by clicking on the 'Installed Applications' tab and manage the application.

Here you will find the name of the application, its path, size and available actions:

  • Create backup
  • Delete application
PE3 34.png

Application Backups

You can also create a backup of your installation. To do so, simply press the 'Create Backup' button next to the installed application.
PE3 37.png
Confirm the action and backup generation will start immediately.
PE3 37 1.png
After a moment you should receive the 'The backup has been created successfully' message confirming that the operation has been performed successfully.

Once you have created a backup of your application, proceed to the 'Backups' tab.
There you will find a lit of created application backups along with the date when they were created.
Use action buttons marked on the screen to restore and delete a chosen backup.

PE3 37 2.png
If you use the Installatron plugin, you can also let your customers create automatic backups for application updates.

To do this, go to 'Addons' 'Plesk Extended' 'Features' 'Configuration' and enable Auto Update Backups.

PE3 37 3.png
Then, when a client installs a new application, it will be possible to toggle the option for automatic update backups and restore them if the application update fails.
PE3 37 4.png

Backups

All available backups are displayed under the 'Backups' section. To add a new one, press the 'Create Backup' button
PE3 24 2.png
Next, add prefix and backup description, choose split size, backup content type and decide whether to make backup 'locally' on Plesk server or on your 'remote' FTP storage.
PE3 24 3.png
The backup creation might take a while. When ready, it can be downloaded by client or deleted from the server.

Important: For a large backup files we strongly recommend to increase the 'max_execution_time' setting in your server's 'php.ini' configuration.

PE3 24 4.png
If you want to use the 'remote' backup type, you will also need to provide the 'FTP Storage Settings' .
PE3 24 6.png
Provide your FTP server IP address or hostname, access credentials, mode, and the directory path to which the backup will be uploaded.
Then, when you create the backup for a second time, select the remote type to upload it directly to your FTP server.
PE3 24 7.png

Databases

Owing to 'Databases' management you can create/delete new databases and users. Press 'Create Database' to add a new database.
PE3 26 1.png
To create a new database, type in its name into the appropriate field and select its type.
Optionally, you can also create a user directly assigned to the database.

Note: that only 'MySQL' and 'PostgreSQL' databases are currently supported and must be enabled in your Plesk panel first.

PE3 26 2.png
You can also delete already assigned users as well as add new ones to particular databases by choosing 'Create Database User' in the 'Users' tab.
PE3 26 3.png

Domain Aliases

Here you can add and manage your domain aliases.

This allows you to read content of one domain from another domain name.
To create a new redirection, press 'Create Domain Alias' .
Note: that domains should be registered with a valid registrar and point to your DNS server.

PE3 29.png
Next, provide your alias domain, chose domain redirections as well as toggle the remaining options.
PE3 29 2.png
After alias creation, you can also rename it, change its settings or delete it.
PE3 29 3.png

DNS Settings

Here you can add and manage DNS records to define the structure and content of the chosen domain name space.
PE3 30.png
Add records by selecting the type and providing their hostname and value.

Press the 'Create Email Forwarder' button, specify the forwarded email and define the destination address.
PE3 26 4.png

FTP Access

In the very first section you are given the possibility to manage your FTP access or create new FTP accounts.

FTP access management is dependent on the system your Plesk panel is set up on.

PE3 24.png
Add and configure FTP Accounts in the easiest way possible.
Just type in your login on a domain, provide or generate a secure password, define directory access and declare available quota.

Note: if you have some other addon domains, creating a FTP account on the main domain will also add it to these domains.

PE3 24 5.png

Spam Filter

The 'Spam Filter' powered by SpamAssassin is designed to identify spam messages among emails sent to mailboxes hosted on your Plesk server.
PE3 26 0 2.png
Enable and configure the filter as desired for the selected mailbox.

You can also adjust sensitivity - by default it might be set to 7 so that all messages with that score or more points will be classified as spam.
If mailboxes receive lots of spam messages with the current setting, to make the filter more sensitive, try setting a lower value, for example, 6.
If any emails are missing because spam filter considers them as spam, try reducing the filter's sensitivity by setting a higher value, for example, 8.

You can also add email messages to a white list that will not be checked by the spam filter, and black list that will block all emails coming from a particular sender.
Simply type domain names in appropriate fields (one domain name per line). Addresses can also contain "*" and "?" wildcard characters, for example, *@domain.com, [email protected]*.com.

PE3 26 0.png

SSL Certificates

This section will allow you to generate or paste ready SSL certificates and private keys.
PE3 34 3.png
Choose 'Generate Certificate' and fill out the required fields. You can also decide whether you want the private key to be automatically generated or provide your own key.
Once ready, you will see it on the list of ready certificates.

Note: the current Plesk API does not give the possibility to preview the automatically generated private key. To do this, you need to log directly into the Plesk panel.

PE3 34 4.png
If you already have a certificate, you can provide it by choosing 'Upload Certificate' .
Next, provide the certificate and domain name, and paste the content of yours 'Private Key (*.key)' , 'Certificate (*.crt)' and 'CA Certificate (*-ca.crt)' files.
Once ready, you should see the provided certificate on the list.
PE3 34 5.png

PE3 36.png

Applications Configuration

Configurable Options For Application Auto Install

Let your clients decide which application they would like to install on their new Plesk account.

While placing an order, your customer will choose an application and along with the account creation, this very application will be installed on the account.
There is nothing else you need to do. Application will be instantly ready for use!
To set up this feature, come back to your product's configuration, find the 'Applications' section, activate 'Install Applications' , choose 'Autoinstaller Type' and activate 'Autoinstall On Create' with 'Use Configurable Options' .

PE3 52 1.png
Next, go back to the features list and click on the download icon to view the list of applications.
PE3 52.png
These are the names of values that you can enter in configurable option fields. We will configure them in the next step.

For example, if you would like to set up 'Drupal 8.3.2' in your applications list, you will need to enter 'Drupal' or 'Drupal|Drupal 8.3.2' into the value field.
1. If you have made a mistake with the application name, the autoinstaller will not work.
2. In the current version, for a variable you have to enter only the application name (without application version number) and only the latest version available on the application list will be installed.
Now that you know what values should be entered in configurable options, we can proceed further.

PE53.png
Go to your 'WHMCS' 'Setup' 'Products/Services' 'Configurable Options' and press 'Create a New Group' .
PE54.png
Enter 'Group Name' of your choice, select product you want to assign configurable options to, then press 'Save Changes' .
PE55.png
Now, click on 'Add New Configurable Option' .
PE56.png
This moment is very important. As 'Option Name' , you have to enter 'Installation App' . Otherwise, the entire functionality will not work.

Here you can set up as many applications as you want. To do so, enter a value name, e.g. 'Wordress |WordPress 4.7.5' and press 'Save Changes' .
Repeat this as many times as you need and do not forget to set 'Option Type' to 'Dropdown' .

Remember that you cannot type the application version number as a variable! Only the latest version available will be installed.

PE57.png
As you can see on the following screen, we decided to offer our customers 5 applications.

When you finish adding the applications, press 'Save Changes' and 'Close Window'.

PE58.png
From the module's 3.1.0 version you can also create a new configurable option - Auto Backup On Update with the 'Yes/No' option type.

This option is used to enable the creation of auto update backups for a first chosen application after the initial order in WHMCS.
Please note that this option works only with the Installatron plugin and Auto Update Backup Enabled By Default On Order setting in the module addon features has to be disabled to make this configurable option work properly.

PE58 2.png
Afterward, come back to 'Plesk Extended Features' 'Configuration' 'Applications' , activate 'Use Configurable Options' and choose 'Apps / Configurable Options' from the dropdown menu.

Please note that you can have more configurable options groups. Press 'Save' . You have just successfully assigned configurable options to the application autoinstall.

PE3 59.png
Let us find out what your customers are going to see in your client area while placing the order.

As you can notice, a dropdown menu with the previously configured applications has appeared.

PE3 60.png

Assignment of Custom Fields To Application Autoinstall

Now that you know how to allow your customers to choose which application they would like to install on their account, we can proceed one step further.

Until this moment applications have been installed with the use of default details like e.g. directory names or database name.
Those details are sent to each customer's email.
Allowing your customers to choose their own installation paths, usernames and others is a safer and recommended solution. Let us see how to do that.
In the beginning, go to 'Product/Services' , find your product using 'Plesk Extended' module and enter the 'Custom Fields' category.
You will need to add 12 custom fields, the first 8 being:

  • Directory
  • Database Name
  • Database Username
  • Database Password
  • Table Prefix
  • Site Name
  • Site Description
  • Language

Remember to set each field type as 'Text Box' , tick 'Required Field ' and 'Show on Order Form'.
Everything is shown on the screen below.

PE61.png
The next 3 fields are:
  • Admin Username
  • Admin Password
  • Admin Email

Set them as 'Text Box' and tick 'Show on Order Form'.

PE61 1.png
The last field is:
  • Auto Update

Set it as 'Drop Down' , enter 'Yes, No' into 'Select Options' , tick 'Required Field ' and 'Show on Order Form'.

PE61 2.png
Once you add all the custom fields, they will appear while placing an order.

Voila! Now your customers can personalize each application without the necessity of installing it later.

PE3 62.png

Custom Installatron Application Language

We will show you how to quickly set a custom language for Installatron web applications.

For this purpose, you need to add a new custom field for your product. The field should be called 'Language' .

PE63.png
Afterward, go to your 'Products/Services' and check whether the 'Language' field has appeared.

In order to change the default application language for a certain account, enter the appropriate value here.

PE64.png
From now on the new field will be visible to your customers as well. While installing a new application, they will be able to choose a desired language by entering its value into the field.

Here you will find a complete list of language codes.

Management of Existing Products

You can easily use Plesk Extended module with your already configured Plesk products.

To do so, change the type of servers and module names of products from 'Plesk' to 'PleskExtended'.
Additional information about how to correctly configure your servers and products can be found at points 8-16 of the 'Installation and Configuration' section.

Billing Management

When you combine Plesk Extended For WHMCS with Advanced Billing For WHMCS, you will be able to set up additional billing options.
PE40.png
The module allows you to charge your customers basing on the server resources used by them.
PE41.png
With Advanced Billing module, you can also display to your customers the current server resource usage and their cost.
PE3 42.png

Tips

1. To set up an account for an existing customer in your Plesk Extended, create a new WHMCS order with the exact same username, password and email address.

Then, set the account status to active.

2. As this module supports templates system, any changes made in the module's templates files will be saved after the upgrade process.

Update Instructions

Essential guidance through the process of updating the module is offered here.

Important: If you are upgrading from Plesk Extended 2.X to 3.X version of the module, you have to delete the old /modules/servers/pleskExtended/ folder (started with a lower case letter) before you start using a new version.
You also need to set recursively writable permissions for storage directories in these two locations:

  1. your_whmcs/modules/addons/PleskExtended/
  2. your_whmcs/modules/servers/PleskExtended/

Then, after activation of the new addon version, all data from the old version of the addon and the product configurations will be automatically migrated to the new version.
In addition, remember to reissue your license due to changes in the folder names.

Note: from 3.0.0 version of the module the cron execution is also no longer required.

Keep in mind there is a quick and easy option in our client area that will let you upgrade the license of your module to an open source version at any time - and at a lower price!
To take advantage of it, simply use the License Upgrade button located on the product's page and a discounted invoice will be generated automatically.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. If you see an error as shown on the screen below, it means that you haven't provided your service plan name or reseller plan name in the product's 'Module Settings'.

Once you enter the name, the problem will disappear.

PE39.png
3. If you are unable to connect with your Plesk server or client area functionalities do not work properly, then make sure that you are connecting with your server on port 8443.

Here you can find more information on how to change the default port in Linux and Windows

4. CURL Error: [6] Could not resolve host.

Try entering your Plesk IP address into the Hostname field in the server configuration.

5. Unable to get the version number from the server. CURL Error: 7 - couldn't connect to host. Check server connection details.

Check connection details and the connection itself between WHMCS and server.

6. Unable to get the version number from the server. Permission denied. You have to set admin account access details.

You need admin account access to use PPPE module. Reseller account API is not supported.

7. Blank page at 'Applications'.

Reason: Some libraries may be missing.
Solution: Make sure you have installed php-xml library.

8. If you have problems with your license, please make sure that the content of the file is correct.

Please note that for Plesk Extended For WHMCS V2.0.0 and later, the license key begins with:

$plesk_extended_licensekey="ModulesGarden_PleskEX_LicenseKey";

Not as it was for the previous versions:

$parallels_plesk_panel_extended_licensekey="ModulesGarden_PleskEX_LicenseKey";
9. In case you see an error: 'Request Is Invalid: Error In Line 5: Element 'owner-id' is not a valid value of the atomic type 'int'.' while creating a product, please verify your product type.
Most probably it is set to 'Dedicated/VPS Server' or 'Other' which are not supported. See point 17 of the installation for more info.
10. If you see an error similar to: 'Unable to find appropriate manager for this version of Panel. Plesk should be at least 8.0 version.' while creating a product, please verify your server configuration.
Make sure that you have SSL 'Secure' ticked in your server configuration, depending on your Plesk settings.
11. Plesk Extended For WHMCS functions only on the administrator account.
12. For a large backup files we recommend to increase the 'max_execution_time' setting in your server's 'php.ini' configuration.
Otherwise, fatal errors like 'Allowed memory size of 134217728 bytes exhausted (tried to allocate 100401152 bytes)' may occur when trying to download local backups.
13. Due to removed support for 'XML API' by Plesk, Plesk Onyx from version 17.8 is only partly supported.

This means the following functionalities:

  • Backups
