When working with Ubuntu, it is often necessary to check the status of services running on the system. This can be done using the systemctl command. Systemctl is a command-line tool used to manage system services, and it provides a variety of options for checking service status.
One of the most common ways to check the status of a service is to use the systemctl status command. This command will print a detailed overview of the service’s status, including its current state, whether it is enabled or disabled, and any error messages that may have been generated.
systemctl status [service name]
For example, to check the status of the Apache web server, you would use the following command:
systemctl status apache2
The output of the systemctl status command will look something like this:
apache2.service - The Apache HTTP Server Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2023-03-09 14:35:34 PST; 3 days ago Docs: http://httpd.apache.org/docs/2.4/ Main PID: 4581 (apache2) Status: "Processing requests" Tasks: 3 (limit: 512) Memory: 9.8M CPU: 1% CGroup: /system.slice/apache2.service 4581 /usr/sbin/apache2 -k startMar 09 14:35:34 hostname systemd[1]: Started The Apache HTTP Server.
As you can see, the output of the systemctl status command provides a wealth of information about the service’s status. This information can be used to troubleshoot problems with the service or to simply monitor its status.
In addition to the systemctl status command, there are a number of other commands that can be used to check the status of services on Ubuntu. These commands include:
- systemctl list-units – This command will list all of the services that are currently installed on the system.
- systemctl is-active [service name] – This command will check whether a specific service is currently active.
- systemctl is-enabled [service name] – This command will check whether a specific service is enabled to start automatically when the system boots.
These commands provide a convenient way to check the status of services on Ubuntu. By using these commands, you can quickly and easily determine whether a service is running, enabled, or disabled.
