Installation and Configuration
This tutorial will show you how to successfully install and configure Proxmox VPS 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. |
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 7.3. 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'. |
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. |
4. Open 'UploadOnProxmoxServer' and upload the 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 VPS For WHMCS for the first time, you have to rename the 'license_RENAME.php' file. The file is located in 'modules/servers/proxmoxVPS/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'. |
6. 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. |

9. Now, we will show you how to configure a new product. Go to 'Setup' → 'Products/Services' → 'Servers' and press the 'Add New Server' button. |
10. Next, enter your server name, IP address, username and password. Choose an authentication type from 'Authentication' and 'Proxmox VPS' from the 'Type' dropdown menus. 'Save Changes'. |
11. After configuring your server correctly, you will see the following screen. In order to check connection with a Proxmox server, simply press 'Test Connection' as shown on the screen below. |
12. It is time to create a server group. To do so, click on 'Create Server Group'. |
13. Enter the name, click on your previously created server, press 'Add' and afterward 'Save Changes'. |
Configuration of Product
14. In order to create and configure a product, go to 'Setup' → 'Products/Services' → 'Products/Services'. Click on 'Create a New Group'. |
15. Enter a product group name and press 'Save Changes'. |
16. When you have a product group, you can assign your product to it. To create a product, click on 'Create a New Product'. |
17. Afterward, choose your product group and its type from dropdown menus, enter your product name and press 'Continue'. 'Product Type' can be set to 'Dedicated/VPS Server' but nameservers will need to be added later. |
18. Now, go to the 'Module Settings' section, choose both 'Proxmox VPS' and your previously created server group from the dropdown menus. Next, 'Save Changes'. |
19. From the dropdown menus choose 'Virtualization Type', 'Default Node' and 'Template & ISO Storage'. Available virtualization types:
You can also specify how often the bandwidth usage should be counted. |
KVM Virtualization Type
20. Setting the KVM virtualization type (skip, if you have chosen the LXC virtualization type). From dropdown menus choose 'KVM OS Type' and 'Default Storage'. |
21. Now, select the desired values in the following fields: 'Storage', 'Disk Type', 'CD/DVD-ROM Type', 'ISO Image', 'Network Mode' and 'Network Model'. Additionally, set up backups in the 'Backups' section by choosing values from the 'Storage' and 'Backups Routing' dropdown menus. |

OpenVZ Virtualization Type
23. Setting the OpenVZ virtualization type (skip, if you have chosen the KVM virtualization type). Please note that OpenVZ virtualization is supported only by Proxmox versions prior to v.2.3.0 From the dropdown menus choose 'Default Storage' and 'OpenVZ OS Template'. |
Finalizing The Configuration
24. Afterward, press 'Generate default' nearby 'Configurable Options' and 'Custom Fields'. |
By doing so, you will add the required custom fields and optional configurable options listed in this table. Note that while generating 'Configurable Options' it is advisable to delete all options which you no longer use, e.g. for the KVM virtualization delete the swap option or IPv6. |
25. At the end of the product configuration you have to add a cron job as shown below (5 minutes intervals are recommended).
php -q /your_whmcs/modules/servers/proxmoxVPS/cron/cron.php Do not forget to replace 'your_whmcs' with your WHMCS root location. The cron can also be run every single minute in order to perform the action more often. |
Congratulations! You have just finished the installation and configuration of the module. |
Configuration of Addon
26. Proceed to 'Addons' → 'Proxmox Addon' → 'Settings' → 'General Settings' and set up cron jobs listed under the 'Cron' section. |
27. Adding a new IP address (if you are not using IP Manager For WHMCS). In order to create a new product, you have to add 'Dedicated IP ' to the 'IP Addresses' list in 'Proxmox' addon module. |
28. Start by typing a desired IP address and mask into 'IP Pool'. Next, choose a server from the 'Server' dropdown menu and define which virtualization it should be applied to through selecting it from the 'Virtualization' dropdown menu. |
29. You are now able to create a new product using the previously added IP address. If you are using the KVM virtualization type, the client area with a successfully created product should look similar to the one on the screen below. |
30.The client area with the LXC virtualization type product looks quite similar. |
Configuration of SSH Keys (KVM)
Important! We highly recommended using the Cloud-Init feature instead of following the instructions described in this section if you are using Proxmox 5.2 or later and the module in the 2.5.0 version or later.
|
31. 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. |
32. Next, while in your WHMCS, go to 'Proxmox Addon' → 'Settings' → 'SSH Keys' and press the 'Add' button. |
33. Enter a name and location to the key pairs located on your WHMCS server. Optionally, you can add a passphrase to increase security. |
34. Then, 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 features you want to use. Make sure they match the 'KVM OS Template' that will be used. |
35. Now, the 'Resize Partition' , 'Change Root Password' and 'Delete VM SSH Root Key' options should be available.
|
The features above mentioned can be also executed in the client area using the options below. |
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 use cloud-init, you need to enable it in the configuration of the Proxmox product. Before you start, we recommend that you learn the details of cloud-init configuration on your Proxmox server first. Click here for more information.
|
In addition, you can allow clients to enter their own public keys for the VM during order so that they can log in to it using their private key instead of a password. To enable this function, go to the 'Custom Fields' tab and add a new 'sshkeys|SSH Public Key' field, select the 'Text Area' type and the 'Show on Order Form' checkbox. Note: This custom field is also auto-generated from the module settings, but with the 'Admin Only' option enabled. Remember to uncheck it to make this field visible to clients. |
Now, when the client places a new order, they will be able to enter the public key here in the OpenSSH format. |
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:
rm -rf /var/lib/cloud/sem/* /var/lib/cloud/instance /var/lib/cloud/instances/* && cloud-init init && cloud-init modules -m final
cat /var/log/cloud-init.log cat /var/log/cloud-init-output.log |
Management
Proxmox VPS allows your customers to manage their PVE accounts via client area in your WHMCS system. You can monitor and manage each product from your WHMCS admin area. |
Admin Area
In the admin area you are able to view details and manage your client's VMs, access VMs consoles and even migrate VMs between nodes. You are also able to add an IP address to a product. To do so, press 'Add New IP' as shown on the following screen. |
Afterward, enter IP address in a textbox and confirm through pressing 'Save Changes'. |
Additionally, until the VM has been provisioned, you can manually assign to it the desired IP addresses from the pool by typing them in the 'Assigned IPs' field (available for 'Dedicated/VPS Server' product type). This will override the automatic IP address assignment and the VM will use only the IP addresses you have entered to that field. Note: The IP addresses you enter must be already existing in the IP Management pool and cannot be assigned to any other VM. This feature will also not work if you already use the IP Manager For WHMCS module. |
Management of Addon
Servers Management
Server List
In 'Addons' → 'Proxmox Addon' → 'Servers' → 'Servers List' you can find the configured Proxmox servers. RAM details:
Suspended - number of suspended accounts per size in MB |
Define ID range and save changes. |
Through pressing 'Edit' you will be moved to the server edit page. |
VMs List
In 'Addons' → 'Proxmox Addon' → 'Servers' → 'VMs List' you can find details of any Proxmox product. |
Use the 'Toggle Filters' button to find entries you are most interested in. |
Recovery VM Lists
In 'Addons' → 'Proxmox Addon' → 'Servers' → 'recovery VM List' you can find the configured Proxmox servers. Run 'recovery cron job' to create and store full backups of VMs configuration. |
IP Management
In the 'IP Management' tab you can add, edit and remove IP addresses of Proxmox products. |
Automatic IP Address Assignment
It is highly recommended to use Cloud-Init to assign IP addresses automatically as DHCP will not be supported since the upcoming releases of the module. For detailed information on how to setup Cloud-Init please follow to the Proxmox official documentation here and here. |
Automatic IP address assignment can be easily applied to your Proxmox module. All you need to do is install 'DHCP' (Dynamic Host Configuration Protocol) and IP addresses will be automatically requested from a DHCP server. As a result, the need to manually configure them will be reduced to the absolute minimum. Important! This option is available only for the 'KVM' virtualization type. When there are no IP addresses assigned to the module, then it will create a VM without any IP address. In that case, you should verify the configuration of your IP Manager. After that you are allowed to run the 'Change Package' command in order to assign IP addresses. Read the section below to learn how to properly install and configure DHCP. |
1. First of all, you must install the SSH2 package on your WHMCS server. Find the precise instructions on how to do that here.
|
2. Now, you may move to ISC DHCP installation and configuration. Follow the steps below:
sudo apt-get install isc-dhcp-server
sudo nano /etc/dhcp/dhcpd.conf
sudo nano /etc/dhcp/dhcpd6.conf Below there is an exampple of how a properly created file should look like: /etc/dhcp/dhcpd.conf. # 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;} }
|
3. Turn on ISC DHCP.
To use the automatic IP addresses assignment feature, select 'ISC DHCP Server' option in 'Module Settings' under the 'KVM Configuration' section. |
IP Manager Integration
Owing to the integration with IP Manager For WHMCS, you are able to easily create subnets with IP addresses and assign them to the desired products. By activating the IP Manager submodule, settings concerning IP addresses such as 'Configurable Options' and 'Default Options' will be ignored by Proxmox VPS. |
3. Afterward, create a new configuration and assign the previously created subnet to it. Note: Multiple IP addresses subnets can be assigned to a single configuration. |
5. Now, enable the integration by proceeding to the '3rd Party Integration' tab. Press 'Activate' next to the 'proxmoxVPS' module type as shown on the following screen. |
6. Next, assign the previously created configuration to the submodule. Press 'Configure' , choose a configuration and press 'Save Changes'. |
If you encounter an error like the one on the below screen while integrating the two products, probably the function 'mb_strlen' is not enabled by default. Please read the manual here for installation instructions. |
Clusters
The 'Clusters' tab contains the list of clusters. To view information about a cluster, simply press its name. |
Here you can find various information about a cluster, from available resource to usage graphs. |
Templates List
Under this page you can view the list of templates. You may also delete unused templates here. |
Create Templates
You can easily convert any KVM VM on your server to a template. In order to convert a VM, go to 'Proxmox Addon' → 'Templates' → 'Create Template'. |
Next, choose a node and VM to convert. Fill out 'Template Friendly Name' and press 'Save Changes'. |
General Settings
'Minimum VMID' allows you to define a minimal ID of a VM created on the server, which does not have any VMID range defined. Cron job user synchronization - if you change a user role in the product settings, this cron job changes the roles of existing users. |
VM Cleaner
VM Cleaner allows you to track VMs existing only on your Proxmox server and that are not visible in your WHMCS. Consequently, you are allowed to sort and delete only those VMs that cannot be managed from your WHMCS. |
SSH Keys
SSH Keys section allows you to manage your SSH key pairs that will be used for your KVM virtualization. These keys will be next used to enable the automatic resizing of a partition upon the disk upgrade as well as the change of a root password on the VM. |
Client Area
Client area interface of Proxmox VPS For WHMCS should look like the one on the screen below. As you can see, control panel contains options useful for managing a VM. |
On the main product page in the client area, under the 'Details' headline your clients can find information about current usage of CPU, memory, disk (LXC only) and SWAP (LXC only). Customers can also view 'DNS' (LXC only) and 'IP Addresses'. |
Client Area - VM Management
VNC Console
VNC console enables your clients to remotely manage their servers. To access it, simply press the 'VNC Console' button. The console requires Java software. You need to accept security risk to run it. |
noVNC Console
noVNC console allows your clients to connect to their server in the easiest possible way. |
SPICE Console
SPICE console enables you to connect to virtual machine using SPICE. Note: Your client needs to download and install client side SPICE application in order to connect with a VM. |
Client Area - Additional Tools
Reinstall
Reinstall feature can be used to reinstall a new OS on the VM by the clients on their own. You can allow your clients to either select a new OS from the provided KVM templates to automatically replace the system, or let them choose the ISO image for manual system installation.
|
You can configure the available 'KVM OS Templates' for clients in the 'KVM Configuration' . |
Similarly, you can choose the available 'ISO Images' from 'CD/DVD-ROM Drive' . |
Remember to also give your clients access to the selected reinstallation types in the 'User's Options' . |
Backups
To create a single backup, press the 'Backups' button and click on 'New Backup' as shown on the following screen. |
Now, choose 'Compress Dump File' and 'Backup Mode' from dropdown menus. Afterward, press 'Add'. |
To restore a VM from backup, press 'Restore' and then click the 'OK' button in a popup window to confirm. |
Backup Jobs
By pressing 'Backup Jobs' in the client area, you will be forwarded to the backup jobs management page. There you can easily edit/delete and preview details of existing backup jobs. |

Press the 'Take Snapshot' button and fill out the form to take a snapshot. Name it (use alphabetical characters only), choose whether to include RAM and add a description. |
Firewall
Owing to the 'Firewall' page, your clients can set up firewall rules and enable a security group for their servers from the WHMCS client area. As you can see, you can easily modify and remove the previously added rules and security groups. |
You can add a firewall rule in two ways. Both of them require choosing a direction, action, interface, source and a destination. The first way (red) is to choose macro from the 'Macro' dropdown field. |
Choose a security group and an interface on which the group will be used. Additionally, you can enable a security group and add a comment to it. |
Disks (KVM only)
View available disks and add new ones. |
Configurable Options
When you successfully set up a product, your client can order it by choosing from the default configurable options. |
In case those options do not suit your needs, you can edit them. Go to 'Setup' → 'Products/Services' → 'Configurable Option' and press the edit button next to the configurable option used by your product. |
Here you can view all the products this configurable option group is assigned to. Now, we will show you how to edit options. Let's say you want to add an option to order a VPS with 4 cores per socket. |
You will see a popup window, so make sure your browser does not block it. To add a new option, enter it in the textbox below all other options. If you want to replace the option you currently have, simply edit the textbox. |

Management of Billing
When you combine Proxmox VPS For WHMCS with Advanced Billing For WHMCS, you will be able to set up additional billing options. The module allows you to charge your customers basing on the server resources used by them. |
With Advanced Billing For WHMCS module, you can also display the current resource usage of your customer's server and its total cost. |
Management of Existing Accounts
You can easily use Proxmox VPS module with your existing Proxmox accounts. To do so, follow the instructions below: 1. Create and configure a Proxmox VPS server and a server group. |
Servers Location Management
Important: Server Allocator For WHMCS is required to allow locations management. In order to allow defining locations for Proxmox VPS, follow the below steps:
Keep in mind that all locations must have exactly the same configuration. |
Now, a client may order a VPS and select 'Location'. Server Allocator For WHMCS will change the server assigned to the product. Create action is triggered on the assigned server due to the 'Server-Node' option enabled. |
Tips
1. Operations performed on the virtual servers are not executed immediately. Give your Proxmox Virtual Environment some time to process the request and execute the 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 just one.
|
3. If you set the product type as 'Hosting Account' when adding a new product, you will not need to fill out nameservers as they will be automatically set up. |
4. 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 they are generated. |
5. OS Templates are loaded from the Storage. Make sure the module can access its content by selecting appropriate permissions for the chosen Storage. |
6. KVM virtualization supports only graphs concerning 'Bandwidth'. Other virtualizations support all graphs. This is due to API limitations. |
7. 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. |
8. As this module supports templates system, any changes made in the module's templates files will be saved after the upgrade process. |
9. If you are currently using 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. |
10. OS Templates serve only as operating systems for a VM, while VM Templates contain complete configuration of a VM, the amount of resources included. |
11. You can use the {$service_assigned_ips} tag in your welcome email template to display automatically assigned IP addresses for created VM (either KVM or LXC virtualization type). |
12. 'One User Per VPS' option allows you to either create a new username for each new client's VM, or create only one that will be then used for every new VM owned by your client. |
13. You can use the 'IPSet IP Filter' option for firewall to prevent IP spoofing. Click here to read more about IP Sets. In the product details view in admin area you can preview the current IP Sets on VM: |
14. You can enable 'Admin Notifications' on product configuration to be informed via email about certain actions. These are:
|
15. 'Minimum Network Rate Limit' option allows you to change the previously entered 'Network Rate Limit' value to a new one if the current 'Bandwidth Limit' is already reached. Note that the 'Bandwidth Limit' can also be used for WHMCS overage billing calculation as described here. |
16. 'Default Username Prefix' - when filling in this field you may use the {$serviceid} parameter to avoid problems with creating usernames that already exist. |
Update Instructions
Essential guidance through the process of updating the module is offered here. Please note that each time you update the module, you have to also update the files on the Proxmox server described in the step 4 of the installation guide.
|
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 the noVNC console. Reason: User account does not have permission to access the noVNC console. To change user role for all clients please use the 'Cron job users synchronization (run only once)' cron command. |
3. Error 'This connection is untrusted' during connecting via the noVNC console. Reason: Your certificate is not valid. |
4. Blank page during connecting via noVNC console. Reason: You have not uploaded the additional files on the Proxmox server. |
5. Error 'Change password failed: user 'xxx' does not exist' Reason: You have not created a client yet. |
6. Error 'Function "ssh2_connect" does not exist. Please Install SSH2 PECL before you start using the script.' Reason: You have not updated the php.ini file |
7. Once you have updated your Proxmox VPS For WHMCS to Proxmox VPS For WHMCS V2.0.0, it is always required to save your product configuration in module settings again. |
8. The current disk usage for the KVM virtualization type is not properly displayed. This is due to API limitations which currently do not return the correct value, which is always set to '0' . |
9. Proxmox VPS For WHMCS does not provide a direct support for HA clusters. |
10. If you want to use cloud-init on Debian, we recommend using the cloud-init's version 18.2 or later to avoid assorted problems occurring in previous versions. |
