Centos – Setting static IP on CentOS without system-config-network

centosipstatic-ip

Background information:
I have a problem installing system-config-network. It appears it cannot find an update to sqlite (checks every mirror and comes back empty handed.) I have tried the skipping broken option and package cleanups from yum-utils.

Since I cannot get it installed, I decided to set an ip manually from console. A quick Google search comes back empty handed as for an easy how-to guide that works. What do I need to do for a currently configured DHCP ip to change it to a Static IP from console.

Thanks,
Josh

Edit the /etc/sysconfig/network-scripts/ifcfg-eth[num] file like this:

DEVICE=eth0
BOOTPROTO=none
HWADDR=<your MAC>
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=<ip>
GATEWAY=<gateway>

When you are done run /etc/init.d/network restart.

Centos – Managing network interfaces on RHEL/CentOS with GUI + scripting (system-config-network)

A question: why would the IT manager want to change network configuration, when he is not even comfortable with a shell? I'd tell him to stay away from production servers if he expects me to do my job right. He does his job (paying me), I do mine (work servers).

Anyway, maybe the 'setup' command can help you out. And how about making /etc/sysconfig/network-scripts a svn or git repository. Than you at least can go back to a previous version. I haven't run into a problem like yours myself, because I tend to script network configuration during deployment, and leave it at that. What you describe sounds like a bug though, so you might want to file a bugreport about inconsequent behavior of that tool.

Setting up puppet for a trivial task like this is not a lot of work by the way, so that might constitute a good solution.

Centos – Problem Assigning Static IP to CentOS Server

The IP Address and gateway are in 2 totally different networks. So change your gateway or IP address to an address within the same network.

NETMASK=255.255.255.0
IPADDR=173.*.*.161    <--
GATEWAY=10.1.10.1     <--
