This tutorial will show you how to successfully install and configure Proxmox Cloud For WHMCS.

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

Installation

1. Log in to our client area and download the module.
PXC2 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 PHP version files should look like this.

PX2 2 1.png
4. Open 'UploadOnProxmoxServer' and upload content of the proper version on all Proxmox servers into the '/usr/share/novnc-pve/' folder.
You should upload these files not only during the first installation of the module, but also each time you update it.

Note: If you wish to allow noVNC consoles, you need to configure a product using the PVE realm and set user permissions to 'PVEVMUser.'

5. When you install Proxmox Cloud For WHMCS for the first time, you have to rename the 'license_RENAME.php' file.

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

PXC2 3.png
6. In order to configure your license key, you have to edit a previously renamed 'license.php' file.

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

  • Select 'Private Bridge'
  • Select 'Private Network Model'
  • Enter ranges for VLAN TAG

Note: Configure these three options for the KVM and LXC virtualization.
If you skip this step, clients will not be allowed to add private networks.

PXC2 20 1.png
24. The next step is setting up the configuration of backups.

Define backup settings in the 'Backups' section through selecting values from the 'Storage' and 'Backups Routing' dropdown menus.
Backups routing automatically removes the oldest backup when a new backup is created and the established backup limit is reached.
Additionally, you can limit the time period for storing backups by providing the number of days into the 'Store The Backup For N Days' field.
Furthermore, you can define the limit of firewall rules and the interface to apply the rules to.
Finish the configuration in the 'Module Settings' tab through pressing 'Save Changes'.
Important: Keep in mind that the root password is generated automatically for the KVM virtualization upon its creation and reset.
If you want to be able to set your own password on the KVM virtualization, go check the Configuration of SSH Keys.

PXC2 20.png
25. Set up server limits to control the size of created servers.
PXC2 21 1.png
26. The final step is generating custom fields and deciding whether to set up the product with static or configurable resources.

Static Resources: Fill in the fields in located in the 'Default Configuration' section with desired values.
Configurable Resources: Click on 'Generate Default' next to 'Configurable Options'.
Press 'Save Changes' at the bottom of the page.
Note: While generating 'Configurable Options', it is advisable to delete the ones you do not use, e.g. the swap option or IPv6 for the KVM virtualization.

PXC2 21.png
27. In the end of the product configuration, you have to add a cron job that is shown below (5 minutes interval suggested).
php -q /your_whmcs/modules/servers/proxmoxCloud/cron/cron.php

Do not forget to replace 'your_whmcs' with your WHMCS root location.

Congratulations! You have just finished the installation and configuration of the module.

Configuration of Addon

28. Add a new IP address.

In order to create a new product, you have to add a dedicated IP pool to 'IP Addresses' list in 'Proxmox' addon module.
To do so, go to 'Addons' 'Proxmox Addon' 'IP Management' and press 'New IP Addresses'.
Note: You can add both IPv4 and IPv6 addresses.

PXC2 30.png
29. Type in the desired IP and mask in 'IP Pool' and choose server from 'Server' dropdown menu.

Select 'Private Address' if the added address is of such a kind, clients will be then allowed to add, remove and configure their private network.
Afterwards, press 'Add'.
Note: Automatic IP assignment works only for OpenVZ/LXC machines.
In case of the KVM virtualization, IP addresses have to be manually added to the pool in Proxmox addon or IP Manager to allow their automatic assignment.
Important: Private IP addresses are not downloaded for the IP Manager module.

PXC2 23.png
30. You are now able to create new virtual machines at the product.

If you used the KVM virtualization type, the client area of a successfully created product should look similar to the one presented on the screen below.

PXC2 24 1.png
31. The client area of a product using the LXC virtualization type looks quite similar.
PXC2 25.png
32. This is how an exemplary product details look like in the admin area.

Allowed actions:

  • Create
  • Suspend/Unsuspend
  • Terminate
  • Change Package
  • Change User Role
PXC2 25 1.png

Configuration of SSH Keys (KVM)

Important! Since the 2.5.0 version of the module, if you are using Proxmox VE 5.2 or later, we highly recommended using the Cloud-Init feature instead of following instructions described in this section.


SSH keys are required to enable the automatic resizing of a partition upon the disk upgrade as well as the change of passwords for the KVM virtualization type.
Note - 'Resize Partition', and 'Change Root Password' will only work for newly created VMs with ISC DHCP and Internet access configuration.
We recommend using this option only for new products.

PXC2 65.png
33. First, create a new VM Template that you will use for the KVM image.

Then, generate SSH keys and add the public key to the root account on the newly created VM image. Moreover, upload both ( public and private ) keys on your WHMCS server in a secure location.

PXC2 66.png
34. Next, while in your WHMCS, go to the 'Proxmox Addon' 'Settings' 'SSH Keys' and press 'Add' button.
PXC2 67.png
35. Enter the name and location to the key pairs located on your WHMCS server.

Optionally, you can add a passphrase to increase security.

PX2 64.png
36. Next, go back to the product configuration and, in ' KVM Configuration' 'VM SSH Root Key' , select the pair of keys you want to use.
Enter the SSH communication port and select the preferred features.
Make sure they match the 'KVM OS Template' that will be used.
PXC2 69.png
37. Now, the 'Resize Partition' , 'Change Root Password' and 'Delete VM SSH Root Key' options should be available.
  • Resize Partition - if a customer upgrades a VM by changing the disk size to a larger one, the size of the last partition in that disk will be automatically increased by the newly added value.
    The feature deletes a current partition table, then creates a new one, according to a new disk size, and reboots the VM.
    These partition types have to be standard, e.g. 'Linux Extended' (Ext2/Ext3/Ext4...), 'Linux SWAP' , 'Solaris' or 'LVM' .
    Important - in case of any failure, all data available on the resized partition might be lost!
  • Change Root Password - this option is responsible for the automatic reset of the password after the VM creation. It also allows users to generate a new root password while using the VM.
  • Delete VM SSH Root Key - it will automatically remove the default SSH key after the VM creation. Use this component to increase security or leave unchecked for resizing partition feature.
    Important - if a customer decides to remove the public key from the VM on their own or the 'Delete VM SSH Root Key' is enabled, it will make the 'Resize Partition' and 'Change Root Password' options no longer working!


From now on, clients will be able to set their own password for newly created VMs.

PXC2 70.png
The partition will be also automatically resized during the VM upgrade if a disk size is different than the one set as default in the template.
PXC2 71.png

Cloud-Init (KVM)

Use Cloud-Init to configure the system during installation, first-boot and package change.
Cloud-Init was initially developed to provide early initialization of cloud instances.
Click here to learn more about Cloud-Init configuration.

Note: Cloud-Init functionality is supported for the KVM virtualization only.

Configuration Of Product

To to allow you clients to use cloud-init you need to enable it in the Proxmox product configuration.

Before you start we recommend to learn the details about cloud-init configuration on your Proxmox server - click here for more details.
Once you get familiar with Proxmox cloud-init proceed to Cloud-Init group of your KVM configuration where you can enable it and set the following:

  • Allow To Set Username - if enabled the client can set its own username during VM creation. Otherwise it will remain unchanged and be set by default as in the template or set from the 'Default User' field if provided.
  • Allow To Set Password - if enabled the client can set its own password during VM creation Otherwise it will remain unchanged and be set by default as in the template.
  • Allow To Set SSH Public Key - if enabled the client can upload its own public SSH key in OpenSSH format during VM creation. This will then allow client to log in to VM using their private key instead of password.
  • Default User - provide the username that wille be used for VM instead of using the 'Service Username' field or image's configured default user. Othewise leave empty.
  • Allow To Set DNS Domain - if enabled the client can provide its own DNS domain for a container. During VM creation, the provided setting will be automatically used if neither a search domain nor a nameserver is set.
  • Allow To Set Nameservers - if enabled the client can set its own nameservers for the VM. Otherwise they will remain unchanged and be set by default as in the template.
PXC2 51 new.png
This is how the above settings will look like in the client area during VM creation.
PXC2 55.png

Configuration Of Proxmox Server

The process of setting up Cloud-Init on the Proxmox server is described here.

Additionally you can use the following commands that can be useful for debugging.

  • Re-run cloud init scripts
rm -rf /var/lib/cloud/sem/* /var/lib/cloud/instance /var/lib/cloud/instances/* &&
cloud-init init  &&
cloud-init modules -m final
  • Logs
cat /var/log/cloud-init.log
cat /var/log/cloud-init-output.log

Management

Proxmox Cloud For WHMCS allows your customers to manage their PVE servers in the WHMCS client area.

At the same time, you can monitor and handle each product from your WHMCS admin area.
To view VM details(1), migrate VM(2), update VMs node(3) or delete VM(4), press a specific button.
To view details of a virtual server created by your client, simply press the 'Load Status' button.

PXC2 26.png
On the following screen, you can see loaded details of the VM as well as opened migration popup.

Migration is useful when you want to request migration from the WHMCS admin area, while editing node is practical for updating details after migrating the virtual machine from the Proxmox panel.

Automatic IP Address Assignment

Automatic IP address assignment can be applied to your Proxmox module, all you need to do is to install 'DHCP' (Dynamic Host Configuration Protocol).
IP addresses will be then automatically requested from a DHCP server. Consequently, the need to manually configure them will be reduced to a minimum.

Important! This option is available only for 'KVM' virtualization type.
Read the below section to learn how to properly install and configure DHCP.

1. First of all, you need to install SSH2 package. You will find precise instructions on how to do that here.
2. Now, you may move to ISC DHCP installation and configuration. Follow the steps below:
  • Install DHCP server package on your Proxmox Node, execute the below command to do so:
sudo apt-get install isc-dhcp-server
  • When ready, configure DHCP server in /etc/dhcp/dhcpd.conf file, run below command to create the file:
sudo nano  /etc/dhcp/dhcpd.conf

Below there is an exemplary content of properly created file: /etc/dhcp/dhcpd.conf.
Take a look at it to see what data should be inside of it:


# Sample /etc/dhcpd.conf
# (add your comments here) 
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.example";
subnet 192.168.1.0 netmask 255.255.255.0 {
#ProxmoxIPv4
host 1 {hardware ethernet 32:62:39:64:33:33;fixed-address 192.168.1.2;}
host 2 {hardware ethernet 32:39:61:31:33:66;fixed-address 192.168.1.3;}
}


  • Key words: #ProxmoxIPv6 #ProxmoxIPv4 suggesting the usage of a specific type of IP address, must be located in the above mentioned file.
Note: Only key word corresponding to a used IP type is required. If you do not use IPv6 then #ProxmoxIPv6 key word is not obligatory.
  • More info about configuring DHCP server can be found here.
3. Turn on ISC DHCP.

To use automatic IP addresses assignment feature, select 'ISC DHCP Server' option in 'Module Settings' under 'KVM Configuration' section.

IP Manager Integration

Owing to integration with IP Manager For WHMCS you are able to easily create IP addresses subnets and assign them to desired products.

Note: This integration works for LXC and KVM virtualization type. OpenVZ is no logner supported.

1. Proceed to IP Manager For WHMCS → Subnets tab in order to prepare IP addresses subnet for Proxmox Cloud For WHMCS.
2. Edit a previously created IP addresses subnet and create custom field 'MAC Address' with desired MAC address at each IP address in the subnet.
More about creating custom fields can be found here.

PX 49.png
3. Afterwards, create a new configuration and assign a previously created subnet to it.

Note: Multiple IP addresses subnets can be assigned to a single configuration.
4. Now, link the configuration with Proxmox Cloud product via product, server or configurable option.
On the following screen we have linked them via a configurable option assigned to the Proxmox Cloud product.

PX 50.png
5. Now, enable integration by proceeding to '3rd Party Integration' tab.

Press 'Activate' next to 'proxmoxCloud' module type as shown on the following screen.

Custom Hooks

Our module allows you to use custom hooks, all you need is knowledge of PHP programming language.

Custom hooks are placed in 'your_whmcs/modules/servers/proxmoxCloud/customhooks.php' .
You can find there all custom hooks and basic information about them.
A full list of available custom hooks:

proxmoxCloud_beforeCreateVM 
proxmoxCloud_afterCreateVM
proxmoxCloud_beforeTerminateVM
proxmoxCloud_afterTerminateVM
proxmoxCloud_beforeCreate
proxmoxCloud_afterCreate
proxmoxCloud_beforeTerminate
proxmoxCloud_afterTerminate
proxmoxCloud_afterSuspend
proxmoxCloud_afterUnsuspend
proxmoxCloud_afterIPAdditionByAdmin
proxmoxCloud_afterIPDeletionByAdmin
proxmoxCloud_afterIPAdditionByUpgrade

Configurable Options

When you successfully set up a product, your clients can order it by choosing from the default configurable options.

Note! If automatically generated configurable options do not seem to fulfill your clients needs, you can edit them using this guide.

Products Autoscaling

If you want to meet the needs of your clients then give them the possibility to scale provisioned servers according to their current load automatically.

To achieve that you need our Proxmox Cloud Autoscaling extension with Advanced Billing For WHMCS product.
Only then, when you have such a combination of products your offer will be full.

PXC52.png
With the combination of these three items, you will be able to formulate a set of rules basing on which specified servers will be modified at the right time.

Advanced Billing For WHMCS will bill your clients for the currently used servers and its extension, Proxmox Cloud Autoscaling, will adjust the size of Cloud product to the current needs.

Tips

1. Operations performed on the virtual servers are not executed immediately. Give your Proxmox Virtual Environment some time for processing the request and execution of operation.
2. Multiple physical Proxmox servers can be joined into one cluster.

When they are joined into one cluster, you can access all of them by connecting to any of them.
While auto-node creates new VM on the server(node) with the most free resources, server-node creates VM on the server(node) which IP address it has (WHMCS's server configuration).

3. OS Templates are not automatically downloaded while configuring a product.
For each virtualization type, templates are downloaded from the Proxmox server depending on which one of them they are generated for.
4. To name the location accordingly to your needs, within the module change the lang into:
$_LANG['node_X']='Your friendly name for node_X';
5. When PAM authentication is used it is necessary to create a client first in order to change the password correctly. Read more about it here.
6. As this module supports templates system, any changes made in the module's templates files will be saved after the upgrade process.
7. If you currently use the module in the 2.3.2 version or previous, and would like to migrate to Proxmox VE V5.X, you need to update the files on your Proxmox server to the new version from the 'UploadOnProxmoxServer' folder.
8. You can use the 'IPSet IP Filter' option for firewall to prevent IP spoofing. Click here to read more about IP Sets.
9. 'Minimum Network Rate Limit' option allows you to change the previously entered 'Default Network Rate Limit' value to a new one if the current 'Bandwidth Limit' is already exhausted.
Note that the 'Bandwidth Limit' can also be used for WHMCS overage billing calculation as described here.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. Error 'Could not create PVE2_API object' during connecting via noVNC console.

Reason: User account does not have permission to access noVNC console.
Solution: Proceed to product's 'Module Settings' tab and check whether selected user permission grant right for noVNC console.
Afterwards, proceed to client's hosting and run 'Change User Role' on it.

3. Error 'This connection is untrusted' during connecting via noVNC console.

Reason: Your certificate is not valid.
Quick Solution: Your client needs to add Proxmox address to certificate exception list.
Best Solution: Configure valid certificate.

4. Blank page during connecting via noVNC console.

Reason: You have not uploaded the additional files on the Proxmox server.
Solution: Open 'UploadOnProxmoxServer' and upload content of proper version on all Proxmox servers into the '/usr/share/novnc-pve/' folder.

5. Error 'Function "ssh2_connect" does not exist. Please Install SSH2 PECL before you start using the script.'

Reason: You have not updated php.ini file
Solution: After SSH2 PECL installation be sure that you have updated php.ini files for CLI and webserver.

6. After you have updated your Proxmox Cloud For WHMCS to Proxmox Cloud For WHMCS V2.0.0, it is always required to save your product configuration in module settings again.
7. If you see an error: 'Invalid VLAN TAG Range' configuration or other when trying to add a new private network, please make sure you have completed all required options in Module Settings.
These are: 'Network Device' → 'Private Bridge', 'VLAN TAG Range From' and 'VLAN TAG Range To'.
8. 'OS Architecture Type ' option for LXC virtualization type is currently not supported as it not implemented in Proxmox itself.
