Getting started
There are 2 common methods used when we discuss how to offset, stop, and restart services on Linux. These ii methods are systemd and init. Both init and systemd are daemon processes designed to manage services on a Linux system and are launched when the organisation is booted upward.

The service command is role of the init daemon. It was used commonly in earlier distributions of Linux based systems to manage services on a system. Allow united states have a look at how to start, end and restart services using the service command.
1. Listing all the services
Before we larn how to kickoff, stop and restart services on Linux using the service command, we need to know how to list all the services using the init daemon. To do then, nosotros employ the following command.
Using this command in the command line will requite an output like to the one seen beneath. Discover that we go a list of all the services on our organisation. In this listing, services preceded by a [+] sign are enabled while the ones preceded past a [-] sign are disabled.
This command can be used to find out the current condition of a service on our system. Else, you can use it to verify that your signal to the system to start, stop or restart a service took effect.
2. Starting a service
Now we will hash out how to start a service. To practice and then, we use the start option of the service command. This option is preceded by the proper name of the service which we wish to start. We type the following command to stop a service on a Linux system.
service <ServiceName> beginning 3. Stopping a service
To end a service using the service command, we apply the stop option. This option is preceded by the name of the service which nosotros wish to cease. Typing the following command volition stop the specified service on your Linux organisation.
service <ServiceName> stop iv. Restarting a service

service <ServiceName> restart Using the systemctl command
The systemctl command is function of the systemd daemon. It is used commonly in newer distributions of Linux based systems to manage services on a system. The systemd daemon was designed to replace the init daemon by offer ameliorate service management efficiency. Let united states have a look at how to start, cease and restart services using the systemctl command.
ane. Listing all the services
Before we have a await at how to start, finish and restart services on Linux using the systemctl command, we need to know how to list all the services using the systemd daemon. To do so, we blazon the following command in our terminal.
systemctl list-unit-files --type service -all 
Using the systemctl command will give an output similar to the one seen below. Notice that nosotros get a list of all the services on our system. In this listing, different the symbolic representation seen in instance of the services command, we get a new cavalcade that holds the status of the services on our arrangement.

systemctl cease <ServiceName> 4. Restarting a service
To restart a service using the systemctl command, we utilise the reoutset option. Like previous examples, this selection is followed by the name of the service which we wish to get-go. The following control helps us restart a service on Linux.
systemctl restart <ServiceName> Conclusion

This is because new services often need to be manually started, while old services need to be restarted in example of configuration changes. We hope this tutorial was able to help you empathize the procedure to start, end, and restart services on a Linux system.
