mod_remoteip replaces the original client IP address for the connection with the UserAgent IP address. It is very useful if Apache is running behind a proxy. Please check out the steps to Install mod_remoteip on cPanel below.

If your cPanel server using EasyApache 3, please follow the steps below:

 
cd /var/cpanel/easy/apache/custom_opt_mods
wget https://documentation.cpanel.net/download/attachments/2326651/custom_opt_mod-remoteip.tgz
tar -xvf custom_opt_mod-remoteip.tgz
rm -f custom_opt_mod-remoteip.tgz

Rebuild Apache using EasyApache. You can find the mod_remoteip module is listed on the “Exhaustive Options List“. Also, please note that Apache 2.4 is needed to install mod_remoteip

 
/scripts/easyapache

install mod_remoteip

 

If your cPanel server using EasyApache 4, please follow the step below:

 
yum install ea-apache24-mod_remoteip

Common steps to follow after installing mod_remoteip:

Once the EasyApache Build is completed, you can verify the installation using the following command.

 
httpd -M | grep remoteip
