The cpanel.config File

server whmadvanced

Valid for version 116

Version:

Overview

The /var/cpanel/cpanel.config file stores settings for WHM’s Tweak Settings interface (WHM » Home » Server Configuration » Tweak Settings).

Note:

You can preconfigure settings before you install cPanel & WHM. For more information, read our Customize Your Installation documentation.

Cached values

To improve performance, the system caches the /var/cpanel/cpanel.config file’s settings in the /var/cpanel/cpanel.config.cache file. This file updates each time that the /var/cpanel/cpanel.config file updates, to keep the cached settings up-to-date.

Configuration setting validation

The settings in the /var/cpanel/cpanel.config file use the key=value format. The system validates each key=value pair whenever you edit these settings. If the system encounters problems during validation, it takes other actions.

Absent cpanel.config file

If the entire /var/cpanel/cpanel.config file does not exist:

The server copies the default /usr/local/cpanel/etc/cpanel.config file and saves it as the /var/cpanel/cpanel.config file.
The server copies the /var/cpanel/cpanel.config.cache file. If the system cannot find the /var/cpanel/cpanel.config.cache file, it will regenerate both the /var/cpanel/cpanel.config.cache and /var/cpanel/cpanel.config files.
For any unset dynamic values, the server attempts to guess the correct value. For example, to set the mailserver value, the server checks whether your system uses the dovecot package.
The server logs the changes to the /usr/local/cpanel/logs/error_log file.

Absent values

If a key doesn’t exist in the /var/cpanel/cpanel.config file, the server attempts to generate a value from the following sources in the following order:

The server copies the key=value pair from the /var/cpanel/cpanel.config.cache file, if it exists.
If the key’s value is static and it doesn’t exist in the /var/cpanel/cpanel.config.cache file, the system copies the key=value pair from the /usr/local/cpanel/etc/cpanel.config file.
If the key’s value is dynamic and it doesn’t exist in the /var/cpanel/cpanel.config.cache file, the server calculates a value.
The server logs the changes to the /usr/local/cpanel/logs/error_log file.

Invalid values

If one or more of the following values are invalid, the server tries to replace them with valid values:

local_nameserver_type
mailserver
ftpserver
