CentOS 7 /RHEL 7: How To Restart/Stop/Start Network Service

I want to restart the network service on my centos 7 system, How to restart/start/stop network service using systemctl command under centos 7 operating system? If the system V init script still can be used to restart/start/stop network service in centos 7 or rhel7? this post will guide you how to restart/stop/start network service using “systemctl” command in centos 7.

CentOS 7 restart network service

In centos 7 or RHEL7, the network service name is changed to “network.service“, issue the following systemctl command to restart network service on your current system:

systemctl restart network.service

or

systemctl restart network

To check the status of network service, run the following command:

systemctl status network.service

Outputs:

[root@devops /]# systemctl status network.service

network.service - LSB: Bring up/down networking

Loaded: loaded (/etc/rc.d/init.d/network)

Active: active (exited) since Tue 2014-12-16 08:02:27 CET; 17s ago

Process: 9491 ExecStop=/etc/rc.d/init.d/network stop (code=exited, status=0/SUCCESS)

Process: 9649 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=0/SUCCESS)

Try to use “service” command to restart network service, type:

service network restart

outputs:

[root@devops Desktop]# service network restart

Restarting network (via systemctl):                        [  OK  ]

From the above output, you will see that service command will redirect to “systemctl“. so I advised that you’d better to use “systemctl” command to restart system service.

CentOS 7 start network service

To start network service on centos 7 system, issue the following command:

systemctl start network.service

or

systemctl start network

CentOS 7 stop Network service

To stop network service on your system, issue the following command:

systemctl stop network.service

or

systemctl stop network

Issue the following command to check the network status, type:

systemctl status network

Outputs:

[root@devops /]# systemctl status network

network.service - LSB: Bring up/down networking

Loaded: loaded (/etc/rc.d/init.d/network)

Active: inactive (dead) since Tue 2014-12-16 08:09:43 CET; 12s ago

Searching the Active line to check the status if it is “inactive(dead)”.

CentOS 7 reload network service

If you just want to reload your netowrk configuration file, just need to reload the network service, issue the following command, type:

or

systemctl reload network

done…
