5. Set User/permissions for the newly copied files :

make sure that files in


has the same user/permissions like any other whmcs file,
mostly the owner must be the apache default user, because it needs to write on some files,
lets assume that your normal whmcs files owner is 'apache' and your WHMCS path is /var/www/html/whmcs/:

cd /var/www/html/whmcs
chown -R apache:apache modules/servers/Xenica
chown -R apache:apache modules/addons/xenica

6. Go to WHMCS and Activate xenica addon module :

Navigate to WHMCS , Setup ⇒ Addon Modules |⇒ Xenica ⇒ Click on “Activate”

7. Visit Xenica addon (WHMCS > Addons =⇒ xenica )

You will be redirected to the Installation Wizard then complete the installation wizard from there.


8. There are 6 steps to complete the wizard

Fig 12 : WebInstall

Step 1. In Step 1 you need to enter your License Key (By clearing the current example value). You can take your code from your client area in servarica.com. —-

Fig 13 : License

Step 2: Installed PHP Versions and extensions will be verified.

Step 3: Directories and Permissions will be verified.

If the directories and permissions are not created correctly , you'll be seeing the below errors.

'rrds' and 'graphs' folders need to be writable by whmcs, so please check folders owner and mod for that,
you may also check the parent Xenica folder owner to make sure all files/libraries have same permissions like other whmcs files,
after changing the owner user try again with the installer, it must complete successfully now.

in special cases if you still get errors, and need to fix this later, you can manually create the directories as described below, but its better to find the problem cause first, because even if you create directories manually you may face related issues later :

 cd /your whmcs directory/modules/servers/Xenica 
 mkdir rrds;chmod 755 rrds 
 mkdir graphs;chmod 755 graphs

Step 4: Configure Xenica module

Step 5: MySQL database and tables will be configured

Step 6: In this Step you can, add your Xenservers to the list of servers in WHMCS

You can ignore this, and add the Servers from WHMCS Menu later (Setup →Products/Services → Servers

Add a cronjob by following the below command

You can use crontab –e and add an every hour cronjob to your WHMCS server

  10 * * * * /usr/bin/php -q /var/www/html/whmcs/modules/servers/Xenica/cron/cron.php

Finally delete temporary install directory by clicking on the Delete Install Directory
if PHP can't delete files you can do that manually :
rm -R whmcs/modules/servers/Xenica/install

Installation Completed :-)
