Static IP address setup

[ironarmchad]

So I have been trying to set-up a static IP for a server that I am running CentOS 7 for. I have tried several different set-up guides using and not using Network Manager but all I have managed to do so far is to either nothing (dhcp assigns IP and nothing changes on the system) or removed internet access. Could anyone give me any tips on what might be going wrong. The current set-up is based on this guide: http://ask.xmodulo.com/configure-static ... ntos7.html, using the "Configure Static IP Address without Network Manager". I have tried with Network Manager as well to no avail. I have also attached the configuration file (with some of the computer/network specific things edited out).

Any help is appreciated.

Congratulation, you managed to mask out from your picture all useful information that anyone might have used to help you.

I am not sure why you need the specific values as they are system specific but here they are:
HWADDR=b8:97:5a:87:b3:90
IPADDR=128.143.18.28
NETMASK=255.255.255.0
NAME=enp2s0
UUID=db4372cc-305b-4d08-8c32-b0225330d07d

hi,
..
just do it

# systemctl stop NetworkManager
# systemctl disable NetworkManager

i dont see GATEWAY=something like 192.168.1.1 --in your conf (ip from router)

also in /etc/resolv.conf put

nameserver 8.8.8.8

# systemctl restart network.service

done

Seems to have worked. Thanks. Given the things I have tried and in different combinations the key here was hard disabling NetworkManager (if anyone is following in my footsteps). Thanks igsmigs88.
