Answer

WARNING: Do not install WHMCS on the same Plesk server which will be managed by WHMCS, since web services will be restarting upon provisioning and it will cause errors in WHMCS.

Note: WHMCS is tested in Linux based environments running the Apache webserver. Other environments such as Windows-based configurations may experience compatibility issues and are not supported.

Note: WHMCS can be installed on servers with Plesk Obsidian, Plesk Onyx 17.8. WHMCS must be used for managing remote Plesk servers. Management of local server (the same Plesk server where WHMCS is installed) is not supported. WHMCS requires "WHMCS Plesk Provisioning Module" in order to manage remote Plesk servers.

Here are the steps to install WHMCS on a domain whmcs.example.com:

Create a new database at Domains > whmcs.example.com > Databases.
Download whmcs.zip file from vendor's site and unpack it to the httpdocs directory of example.com via Domains > whmcs.example.com > /httpdocs.
Rename the file configuration.php.new to configuration.php and set write permissions to this file.
Set PHP version to 5.6 at Domains > whmcs.example.com > PHP Settings.
Open the link https://whmcs.example.com/install/install.php and go through the installation steps.
Remove the directory /var/www/vhosts/whmcs.example.com/httpdocs/install/.
Access the admin panel at https://whmcs.example.com/admin.

If it is required to install "WHMCS Plesk Provisioning Module"

WHMC has the module pre-installed, however, if it is missing, it can be installed using these steps:

Connect to the server via SSH;
Download module from https://github.com/plesk/whmcs-plugin as zip archive.

# cd /root && wget https://github.com/plesk/whmcs-plugin
On server create folder named "plesk" and copy all module files to it.

# mkdir /root/plesk/
Put this folder to <WHMCS-root-directory>/modules/servers/ on your server . For example, folder is /var/www/vhosts/whmcs.example.com/httpdocs/modules/servers/:

# cp -a /root/plesk /var/www/vhosts/whmcs.example.com/httpdocs/modules/servers/
Log out from WHMCS and log into WHMCS as administrator.
The appropriate type of server ("Plesk") is now added to server types list and product setting "Module Name".
