Linux network auto boot and restart
Centos 7 network is disabled by default after installation and initialization, which causes network connection can not be made until you manually turn on it
That is such annoying when you usually use SSH tool remote connect to centos workstation or server, so it’s quite necessary to turn on the network automatically every time reboot machine or VM. To accomplish that, we need to modify the network configuration file.
Auto Boot Network
VIM open config file: /etc/sysconfig/network-scripts/ifcfg-ens33
1 | vim /etc/sysconfig/network-scripts/ifcfg-ens33 |
Revise the ONBOOT value to be “yes”
Save and quit config file by :wq vim command
Restart Network
To be able to make that change taking effect, network needs to be restarted by below command
1 | systemctl restart network.service |
something trick here is some blog articles mention that part is only systemctl restart, which won’t work if there is no network.service, I confuse and spend many time to figure out that, thanks to CodeSheep whose video shed the light on it and help me to solve that problem.
