Thank you for your attention.
But the mentioned problem associated with CentOS.
Network configuration, running CentOS 4.9 and 5.7 versions:

For eth0 :

Code:
DEVICE=eth0 
BOOTPROTO=none 
BROADCAST=XXX.XXX.XXX.XXX 
HWADDR=00:0C:29:EA:F0:xx 
IPADDR=XXX.XXX.XXX.XXX 
NETMASK=XXX.XXX.XXX.XXX 
NETWORK=XXX.XXX.XXX.XXX 
ONBOOT=yes 
TYPE=Ethernet
For eth0:1

Code:
DEVICE="eth0:1" 
ONBOOT="yes" 
IPADDR=XXX.XXX.XXX.XXX 
BOOTPRO=static 
NETMASK=XXX.XXX.XXX.XXX
For eth0:2

Code:
DEVICE="eth0:2" 
ONBOOT="yes" 
IPADDR=XXX.XXX.XXX.XXX 
BOOTPRO=static 
NETMASK=XXX.XXX.XXX.XXX
For eth0:3

Code:
DEVICE="eth0:3" 
ONBOOT="yes" 
IPADDR=XXX.XXX.XXX.XXX 
BOOTPRO=static 
NETMASK=XXX.XXX.XXX.XXX
...

The same settings does not work on CentOS 6.2.

I added ip with CentOS 6.2 network manager. IP addresses are added to the running. But does not recognize the cPanel. Old as in the version I need to add. separate adapter for each rope in cPanel logic. For example, eth0, eth0: 1, eth0: 2, eth0: 3, eth0: 4, as I need to add ip.

Current CentOS 6.2 eth0 configuration :

Code:
DEVICE=eth0:1 
TYPE=Ethernet 
BOOTPROTO=none 

IPADDR=XXX.XXX.XXX.XXX
IPADDR1=XXX.XXX.XXX.XXX
IPADDR2=XXX.XXX.XXX.XXX
IPADDR3=XXX.XXX.XXX.XXX
PREFIX=27 

NETMASK=XXX.XXX.XXX.XXX
GATEWAY=XXX.XXX.XXX.XXX 

DNS1=XXX.XXX.XXX.XXX
DNS2=XXX.XXX.XXX.XXX 
DNS3=XXX.XXX.XXX.XXX 
DEFROUTE=yes 
IPV4_FAILURE_FATAL=yes 
IPV6INIT=no NAME=eth0 
ONBOOT=yes 
BRIDGE=br0 
MTU=9000 
DOMAIN=google.com
HWADDR=00:0C:29:49:C8:xx

Add to doing this.
But you get the error at system startup:
Biridging up eth0:cp1 error (Device not found)
Skipping the load eth0:cp1
Bridging up eth0:cp2 error (Device not found)
Skipping the load eth0:cp2

Ongoing in the form I get an error. I added the strings do not seem to cPanel.
I want to add again after error : Ip address already exists this system. I get the error again.

My CentOS 4.9 network config not work in CentOS 6.2. I use add ip via cPanel worked on CentOS 4.9. But not work this section CentOS 6.2.

I have just come up across this too.

Adding the IP into cPanel seems to add it into cPanel but there is no reference to the IP anywhere in /etc

Oddly the interface exists in ifconfig but does not pass any traffic and if I restart networking the interface disappears. I'll raise a ticket because I need to be able to add a different subnet mask too!

Ticket 2409927 raised as I have noticed a couple of extra bugs. Namely that running "service network restart" apparently removes the eth0:cp1 interface and I haven't figured out a way to bring it back without removing and re-adding it. That would be a fairly big problem once services are active on the IP!

The advice that came back from cPanel is to only add IP addresses through WHM if WHM is all you use for managing the server. If you are familiar with the console then just add the IP in the traditional manner for your OS. I'm up and running that way nowand don't have to worry about which command I run to restart.

Hello all.

My problem is resolved.

Resolving section is :

Need download netinstall iso files and via network setup.
HDD format after select minimal and click costumize checkbox click next button.
See packages and select only Base and Server Platform.
Setup and reboot your machine after install cPanel worked perfectly.

Thank for all your support. Good works.
