CentOS and RHEL 7 Restart, Stop, Start Networking Commands

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

OR

sudo systemctl status network

CentOS 7 / RHEL 7 restart network service

sudo systemctl restart network.service

OR

sudo systemctl restart network

CentOS 7 / RHEL 7 start network service

sudo systemctl start network.service

OR

sudo systemctl start network

CentOS 7 / RHEL 7 stop network service

sudo systemctl stop network.service

OR

sudo systemctl stop network

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.
