The sysinfo.config File


Last modified: May 22, 2019

Overview

The /var/cpanel/sysinfo.config file stores the server’s system information settings. cPanel & WHM uses this file to determine which RPMs to download during installation and upgrades.

If the detection system fails to correctly identify the distribution or version of Linux, you can manually override those settings.

Warning:

This feature is for advanced users only. Changes that you make to the default configuration may render your server nonfunctional. Exercise caution when you edit this file.

Initial settings

cPanel & WHM runs the /usr/local/cpanel/scripts/gensysinfo script as part of nightly maintenance to automatically generate the sysinfo.config file. The system will not update the file if it is less than a day old.

If the sysinfo.config file does not exist or becomes corrupt, log in to the server via SSH as the root user and run the /usr/local/cpanel/scripts/gensysinfo script to generate a new file.

Keys and default settings

The following table lists the keys that the system stores in the /var/cpanel/sysinfo.config file:
