How to use systemctl to manage Linux services

Suppose you're making configuration changes to a Linux server. Perhaps you just fired up Vim and made edits to the /etc/ssh/sshd_config file, and it's time to test your new settings. Now what?

Services such as SSH pull their settings from configuration files during the startup process. To let the service know about changes to the file, you need to restart the service so that it rereads the file. You can use the systemctl command to manage services and control when they start.

Creating A Linux Service

This tutorial is for creating a custom Linux service that will automatically run on system startup.

This service will automatically run python server on system boot. To be used in development services. Please take note that this method is not suitable for production as it uses Python’s simple http server.

STEP 1: In your computer, create a file with a .service extension. Please be sure to hide the .service file. In my case, I saved the .service extension at etc/systemd/system

ex. sample.service

The content of the sample.service file looks like this

[Unit]

Description=Sample Service description goes here

After=network.target

[Service]

Type=simple

User=root

ExecStart= -/usr/bin/bash -c ‘cd /home/Documents/pythonproject; source env/bin/activate; python manage.py runserver’

TimeoutStart=0

[Install]

WantedBy=default.target

NOTES:

-/usr/bin/bash

this access the terminal

-c

shortcut for command

‘cd /home/Documents/pythonproject; source env/bin/activate; python manage.py runserver’

The sample command in running python project in terminal

;

equivalent to ‘Enter’ key in terminal

STEP 2: Enable the systemctl service unit

In your terminal type the following

systemctl daemon-reload

systemctl enable sample.service

systemctl start sample.service

systemctl reboot -i

The last command will reboot your computer

NOTES:

sample.service

denotes the name of the service file that we created in step1

STEP 3: Check the status of the created service

To check if the created script was running as expected. type the following in your terminal

systemctl status sample.service

A message will show if the service was properly loaded and will show errors as well

NOTE: Check your firewall

Check if the port you are hosting is available on firewall

firewall-cmd --zone=public --add-port=8000/tcp --permanent

Then remember to reload the firewall for changes to take effect.

firewall-cmd --reload

Increasingly, Linux distributions are adopting or planning to adopt the systemd init system. This powerful suite of software can manage many aspects of your server, from services to mounted devices and system states. In systemd, a unit refers to any r

Systemd is an init system and system manager that is widely becoming the new standard for Linux machines. While there is considerable controversy as to whether systemd is an improvement over the init systems it is replacing, the majority of distributi
