Configuring Static Networking and IPv6 on CentOS 7

VULTR has recently made changes on their end, and everything should now work fine ‘out of the box’ with NetworkManager enabled. Should you wish to disable NetworkManager, you can follow these steps.

Pasted below is an example /etc/sysconfig/network-scripts/ifcfg-eth0 file. This template configures IPv4/IPv6 statically. Substitute DNS/HWADDR/IPADDR/GATEWAY/IPV6ADDR from your existing configuration.

DNS1=123.123.123.123ONBOOT=yesBOOTPROTO=staticDEVICE=eth0IPADDR=123.123.123.123PREFIX=23GATEWAY=123.123.123.123DEFROUTE=yesNM_CONTROLLED=noIPV6INIT=yesIPV6ADDR="2001:1234:1234:1234::64/64"IPV6_AUTOCONF=yes

Then, disable NetworkManager and restart networking:

systemctl stop NetworkManagersystemctl disable NetworkManagersystemctl restart network

Don’t forget, should you lose access to your box you can use the VNC console from the control panel.
