CentOS / RHEL 7 Restart / Stop / Start Networking Command

I recently installed CentOS Linux version 7 or Red Hat Enterprise Linux version 7. How can I restart networking service using command line options? How can I start / stop and restart networking service on a CentOS/RHEL 7 based system?

CentOS 7 / RHEL 7 / Fedora Linux (many other modern distor) uses Systemd. It is a system and service manager for Linux operating systems. In newer distro such as CentOS7/RHEL7 systemd replaces Upstart as the default init system.

In older versions of CentOS or Red Hat Enterprise Linux, you used init scripts located in the /etc/rc.d/init.d/ directory. These init scripts were typically written in Bash, and allowed the system administrator to control the state of services and daemons in their system. In CentOS/RHEL 7, these init scripts have been replaced with service units.

CentOS 7 / RHEL 7 networking service name

To bring up/down networking service you need to use the network.service.

Say hello to systemctl command

Use this command to control the systemd system and act as a service manager.

CentOS 7 / RHEL 7 get status of network service

sudo systemctl status network.service


sudo systemctl status network

Sample outputs:

CentOS 7 / RHEL 7 restart network service

sudo systemctl restart network.service


sudo systemctl restart network

CentOS 7 / RHEL 7 start network service

sudo systemctl start network.service


sudo systemctl start network

CentOS 7 / RHEL 7 stop network service

sudo systemctl stop network.service


sudo systemctl stop network

Sample outputs:

A note about old service and chkconfig command

The service and chkconfig commands are still available in the system and work as expected, but are only included for compatibility reasons and should be avoided as may be dropped in future release.

Hi there,

Before anything else good article and thanks for it ;) just a quick add to it, Firewall in CentOS 7 works a bit differently than previous ones has I noticed, so if anybody is having difficulty accessing the Nagios web GUI at the end, try adding this firewall rules for ports 80 (http) and 443 (https):

[root@nagios-server /]# firewall-cmd –permanent –zone=public –add-service=http
[root@nagios-server /]# firewall-cmd –permanent –zone=public –add-service=https
[root@nagios-server /]# firewall-cmd –reload

And after that you should now be able to access the web GUI with no problems ;)

Best ragards

Just in case anyone is wondering what is the equivalent of the chkconfig servicename on/off is:

systemctl enable servicename
systemctl disable servicename

The Fedora people put a nice cheatsheet over here https://fedoraproject.org/wiki/SysVinit_to_Systemd_Cheatsheet

I like Centos 7 so far but Systemd can die in a fire. I want my SysV init scripts back.

Your firewall commands didn’t work with my fresh CentOS 7 install.
I had to do the follwoing to access my webserver/httpd remotely:

[code]firewall-cmd --permanent --zone=public --add-port=80/tcp
systemctl restart firewalld.service[/code]

A lot of new things in CentOS 7. I think, it isn’t easy for IT people to change the configurations from CentOS 6.X to 7.0 (short but big change!?), not easy to follow in this time.
