How to restart cpanel service via SSH

This document show how to restart cPanel sevicese from SSH command line

The first is to use the service command to issue commands to the service you wish to work with. For example: service httpd restart This will issue a restart command to Apache.
The second would be to directly interact with the init script on the server. An example of this would be, /etc/init.d/httpd restart This will issue a restart command to Apache.

Below are some examples of various common services and their usage flags:

Apache

One of the primary reasons Apache may need to be restarted would be after changes have been made to the configuration file in order to optimize performance.

srv6# /etc/init.d/httpd usage: /etc/init.d/httpd (start|stop|restart|fullstatus|status|graceful|configtest|help) start - start httpd startssl - start httpd with SSL enabled stop - stop httpd restart - restart httpd if running by sending a SIGHUP or start if not running fullstatus - dump a full status screen; requires lynx and mod_status enabled status - dump a short status screen; requires lynx and mod_status enabled graceful - do a graceful restart by sending a SIGUSR1 or start if not running configtest - do a configuration syntax test help - this screen

Mail

On cPanel servers the default mail service is exim. Any configuration changes to exim will require a restart to take effect.

srv6# /etc/init.d/exim Usage: exim {start|stop|restart|status}

On Plesk servers the default mail service is qmail. Any configuration changes to qmail will require a restart to take effect.

srv6# /etc/init.d/qmail Usage: /etc/init.d/qmail {start|stop|status|reload|condrestart|restart}

SSH

Any change to the ssh configuration file(such as changing the SSH port) require a restart to take effect.

srv6# /etc/init.d/sshd Usage: /etc/init.d/sshd {start|stop|restart|reload|condrestart|status}

FTP

On cPanel servers the default FTP program is pure-ftp. Any configuration changes to pure-ftp will require a restart to take effect.

srv6# /etc/init.d/pure-ftpd Usage: pure-config.pl {start|stop|restart|condrestart|status}

MySql

srv6# /etc/init.d/mysql Usage: /etc/init.d/mysql start|stop|restart|reload

Firewall

On managed Liquidweb servers the firewall of choice is APF. The APF firewall interacts with the iptablesservice. If any configuration changes are made to APF the service must be restarted in order for the changes to take effect.

srv6# /etc/init.d/iptables Usage: /etc/init.d/iptables {start|stop|restart|condrestart|status|panic|save}

srv6# /etc/init.d/apf usage: /etc/init.d/apf [start|stop|restart]
