RHCE Study Notes (8) service Management

RHEL7 Service Management is also a relatively simple content, mainly through the SYSTEMCTL command on the service to start, close, query and other operations.

It is worth mentioning that before the RHEL6 version, is the service XXX start/stop/status command to perform the operation of services, which still works in RHEL7, but only the most basic functions can be performed

For example, stop the SSHD service, view the status, open the SSHD service

Similar commands can be implemented with SYSTEMCTL.

View status

Stop Service

Status indicates dead, service has stopped

Can also disable service, disable the automatic operation of the boot

Boot auto-load and start the service

The service can be disabled through mask so that once the service is terminated, it cannot be restarted and must be de-disabled by unmask to run the service using SYSTEMCTL start sshd

In addition to the basic functionality mentioned above, SYSTEMCTL can also query the currently loaded module unit, noting that the suffix service is the one we need to manage

You can filter out other types of cells by type

If we make changes to the relevant service configuration, we must restart the service to take effect, such as to restart the Network service after modifying the IP address
