network interface does not come up automatically after reboot

 


Some times it happens server network interface doesn't come up automatically after remote or hard reboot.

In this case you need to check few things on the server whether all these things are configured properly.

1) Check firewall rules if you are managing any firewall rules manually otherwise it should be inactive mode.

2) Check LAN port it should be set on automatically connection mode.

3) Enable network manager- systemctl enable NetworkManager

3) Network-Scripts (Check ONBOOT-Please set  YES if it is not set already )


GOTO- /etc/sysconfig/network-scripts/
