Just for me to record the things that worked for me changing ip addresses, gateways etc.. 😉
* vi /etc/sysconfig/network-scripts/ifcfg-(name of interface) <- get this via ifconfig.
* add METRIC if needed or have multiple interfaces
* service network restart , to restart the network
Gateway:
* ip route show
* ip route replace default via 192.168.91.10 dev eth0 (if needed to change the default gateway)
* add/change gateway=ip.address.gateway. to /etc/sysconfig/network (for permanent changes, or change the ifcfg file in /etc/sysconfig/network-scripts dir)
Example /etc/sysconfig/network-scripts/ifcg file:
