CentOS 7 – No Network Connection

KB ID 0001047 Dtd 01/04/15

Problem

A while ago I spun up a CentOS server in VMware Workstation, and I could not get it connected to the network, I was in a bit of a hurry, so I blew it away and just built a new server with CentOS 6. This week I've been using VirtualBox and spun up a new CentOS 7 server and had the same problem.

Solution

1. Quite why CentOS 7 does this I'm not sure, My NIC is called enp0s3 (run 'ip addr' to find yours). Then take a look at;

cat/etc/sysconf/network-scripts/{interface name}

CentOS7 ONBOOT

As you can see (above), the ONBOOT section is set to 'no'.

2. Use the VI editor (because you wont have Nano installed yet) to edit the file (Press I to insert > Edit the file > Escape > :wq {Enter}).

3. Reboot the server, and now we have comms!
