Network Manager

Hi all, if we disable Network Manager in Centos 7 as per CyberPanel guides, how can we add a second IP address to Centos 7 so that we can assign it to the relevent listener in OLS Webadmin? The reason I need to do this is to assign a website a dedicated IP address. Thanks in advance for any help.

I have got as far as adding the IP address in Centos 7 by: -
Editing /etc/sysconfig/network-scripts/ifcfg-eth0 by adding:
Then restarting Network Service:
systemctl restart network.service

I ran ip addr which shows that the second IP is there, but when I go into OLS webadmin I cannot see the ip address in the Listeners > Add > IP Address dropdown. This is the list: ANY,,, [ANY] IPv6, [::1], []

Note: I have put the main internal IP address of the server as

Can anyone please tell me if I setup the second IP wrong in Centos or if I need to do something else in OLS webadmin?

if you run “ip a”

you see the new IP in result ?

I got it working. I needed to make a copy of the ifcfg-eth0 file called ifcfg-eth0:1. The copied file should include the new IP. Then restart the server.
