This is for CentOS\/RHEL based servers.<\/p>\n

Steps in WHM: Log into WHM and go to Basic cPanel & WHM Setup.<\/p>\n

Change the Primary IP here with the option that says “The IP address (only one address) that will be used for setting up shared IP virtual hosts”<\/p>\n

Log in to SSH, and do the following:<\/p>\n

Edit \/etc\/sysconfig\/network-scripts\/ifcfg-eth0
\nChange the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip<\/p>\n

Edit \/etc\/sysconfig\/network
\nChange the GATEWAY line here if it does not exist in the ifcfg-* file.<\/p>\n

Edit \/etc\/ips
\nRemove the new primary IP from this file if it is present
\nAdd the old primary IP to this file with the format <\/p>\n

\n\n <IP address>:<Net Mask>:<Gateway>\n\n<\/pre>\n
Edit \/var\/cpanel\/mainip
\nReplace the old primary IP with the new primary IP<\/p>\n
Edit \/etc\/hosts
\nReplace the old primary IP with the new one if needed. The hostname’s dns will need to be updated too<\/p>\n
Restart the network service to make the new IP the primary<\/p>\n
\n# service network restart\n\n<\/pre>\n
Note: You’re probably going to be disconnected at this point, and have to log in to ssh using the new primary ip.<\/p>\n
Restart the ipaliases script to bring up the additional IPs<\/p>\n
\n# service ipaliases restart\n\n<\/pre>\n
Run ifconfig and make sure all IPs show up correctly<\/p>\n
Update the cpanel license to the new primary IP<\/p>\n
Verify you can still log in to WHM and there is no license warning<\/p>\n","protected":false},"excerpt":{"rendered":"
