What is the Linux service restart command?

Linux service restart and reload

In Linux operating system service management, restart and reload are often encountered.

What is the difference between these two parameters? Now I will briefly talk to you.

In the learning environment, we often use the restart parameter to restart the service, but it may not be reasonable in the production environment.

restart: It means restarting. As the name suggests, you need to stop first and then start.

reload: The meaning is not reloaded, as the name implies, it is reloading (configuration).

Let’s briefly talk about the sshd service:

We have modified the configuration file of the sshd service, and now we need to reload the configuration or restart

service sshd restart:

If the changed configuration is wrong and you execute this command, stop will definitely succeed; but start will not start; if the device is in a far away computer room, this will undoubtedly cause problems for the operator. Maintenance work increases the burden; even if there is no problem with the configuration, starting and stopping the service will cause the service to stop temporarily.

service sshd reload:

Reload means reloading the configuration. First, reload will not affect the session that has been established by the current service, but will directly load the new configuration. When a new session is generated, the configuration of the new information will be used; even if the configuration file is incorrect, the result will only be a failure to load the configuration and has nothing to do with the services provided.
