Linux is quite stable, but there are times that you may have to restart an application or a service after a configuration change. For the change to take effect, a restart of a service is required. The good news is starting and stopping services in Linux are quite easy.
The old way.
# Starting and stopping MySQL $ sudo /etc/init.d/mysql start $ sudo /etc/init.d/mysql stop $ sudo /etc/init.d/mysql restart # Starting and stopping Apache $ sudo /etc/init.d/apache2 start $ sudo /etc/init.d/apache2 stop $ sudo /etc/init.d/apache2 restart # Starting and stopping the network $ sudo /etc/init.d/networking start $ sudo /etc/init.d/networking stop $ sudo /etc/init.d/networking restart |
Via service for Debian|Ubuntu distros
# Starting and stopping MySQL $ sudo service mysql start $ sudo service mysql stop $ sudo service mysql restart # Starting and stopping Apache $ sudo service apache2 start $ sudo service apache2 stop $ sudo service apache2 restart # Starting and stopping the network $ sudo service networking start $ sudo service networking stop $ sudo service networking restart |
Via Systemctl for CentOS|Redhat distros
# Starting and stopping MySQL $ sudo systemctl start mysqld $ sudo systemctl stop mysqld $ sudo systemctl restart mysqld # Starting and stopping Apache $ sudo systemctl start httpd $ sudo systemctl stop httpd $ sudo systemctl restart httpd # Starting and stopping the network $ sudo systemctl start network $ sudo systemctl stop network $ sudo systemctl restart network |
