if and never experienced a problem like this, which adds a dedicated IP hosting server, but we can not meet IP UP, and when we try to restart the service IP aliases test, encountered the following error:
Bringing up eth0:cp1 Cannot find device "eth0"
Routing 192.168.0.123 Cannot find device "eth0:cp1"
then the solution is as follows:
just set on WHM > Basic cPanel/WHM Setup > Alternate Main Ethernet Device > to the main NIC device
Problem solved! :b
