Good evening,

I am attempting to install cPanel and the installer asked me to disable NetworkManager. I have went ahead and did the instructions that was listed here. The cPanel installation goes through and installs. I went ahead and logged into the WHM interface to setup and was finished and was told to reboot to finish updating kernels. I went ahead and rebooted through WHM and the server rebooted successfully (via KVM) but was unable to connect to the internet. I am unable to ping the server from my side. I can access the server fine through KVM but not through WHM and/or SSH.

I saw the warning on the How to Disable Network Manager article were it explicitly says:
  • Exercise extreme caution when you disable the Network Manager. Your server may lose its network services if you do not disable Network Manager correctly.
What did I do wrong? I am running CentOS 7 latest version minimal install. I have tried looking through Google and couldn't find anything besides the cPanel article on How to Disable Network Manager.

Thanks,
apt

Hi @aptechnologies

It's hard to know what specifically went wrong here. If you're able to access the server through KVM can you show me the changes you made to ifcfg-eth0 and ifcfg-lo?

Can you also ensure you restarted the network services?

Code:
systemctl enable network.service
systemctl start network.service
