Checking Service Standing After Restart
Upon getting restarted a service utilizing sudo, it is very important confirm that the service has been efficiently restarted and is operating as anticipated. Listed here are the steps on easy methods to test the standing of a service after restarting it:
Utilizing the systemctl Command
The systemctl command is a flexible software that can be utilized to handle systemd providers. To test the standing of a service utilizing systemctl, run the next command:
“`
sudo systemctl standing [service name]
“`
For instance, to test the standing of the Apache internet server, you’d run the next command:
“`
sudo systemctl standing apache2
“`
Utilizing the service Command
The service command is another choice for checking the standing of a service. To make use of the service command, run the next command:
“`
sudo service [service name] standing
“`
For instance, to test the standing of the Apache internet server utilizing the service command, you’d run the next command:
“`
sudo service apache2 standing
“`
Utilizing the ps Command
The ps command can be utilized to show details about operating processes. To test if a service is operating utilizing the ps command, run the next command:
“`
sudo ps -ef | grep [service name]
“`
For instance, to test if the Apache internet server is operating utilizing the ps command, you’d run the next command:
“`
sudo ps -ef | grep apache2
“`
If the service is operating, you will note a line just like the next within the output of the ps command:
“`
[user] [pid] [cpu] [mem] [command]
www-data 1234 0.0 0.1 /usr/sbin/apache2 -k begin
“`
Utilizing the netstat Command
The netstat command can be utilized to show details about community connections. To test if a service is listening on a particular port, you should utilize the netstat command. For instance, to test if the Apache internet server is listening on port 80, you’d run the next command:
“`
sudo netstat -lnp | grep 80
“`
If the service is listening on the port, you will note a line just like the next within the output of the netstat command:
“`
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1234/apache2
“`
Utilizing Service Unit Names with Systemd
With systemd, every service is recognized by a novel unit identify. To restart a service utilizing its unit identify, use the next syntax:
sudo systemctl restart unit-name
For instance, to restart the Apache internet server, you’d use the next command:
sudo systemctl restart apache2
You may as well use the standing command to test the standing of a service. The next command will present you the standing of the Apache internet server:
sudo systemctl standing apache2
The output of the standing command will present you whether or not the service is operating, stopped, or in a failed state. It should additionally present you any error messages which will have been generated.
If the service isn’t operating, you should utilize the begin command to start out it. The next command will begin the Apache internet server:
sudo systemctl begin apache2
If the service is already operating, the begin command can have no impact.
You may as well use the cease command to cease a service. The next command will cease the Apache internet server:
sudo systemctl cease apache2
If the service is already stopped, the cease command can have no impact.
Here’s a desk summarizing the systemctl instructions that can be utilized to handle providers:
| Command | Description |
|---|---|
systemctl begin unit-name |
