Enter current WHMCS Path:/var/www/html/whmcs/
You have entered WHMCS Installation current directory: /var/www/html/whmcs/
Are you sure?[Y/N]y
Xenica Source Found..Extracting it. Wait....

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

make sure that files in


has the same user/permissions like any other whmcs file,

the owner must not be root , because apache needs to handle those 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” Once You click activate, Click the configure button and Assigning roles like “Full Administrator” For this add-ons.

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,kickstarts and graphs folders need to be writable by apache , you may check the parent folder owner to make sure that its apache user (and is not root , that apache can't write to root folders) , after changing the owner user try again with the installer, it must complete 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 kickstarts;chmod 755 kickstarts
 mkdir graphs;chmod 755 graphs

Step 4: Configure the 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
