CentOS is a popular open-source operating system that is widely used in the IT industry. One of the most important tasks when managing a CentOS server is to monitor and manage the services running on it. In this article, we will discuss how to list services in CentOS and provide examples that illustrate the process.
What are Services in CentOS?
Services are programs or processes that run in the background of a CentOS server. They are responsible for managing various tasks, such as network connectivity, file sharing, and software updates. Services can be started, stopped, or restarted, depending on the needs of the system administrator.
How to List Services in CentOS?
CentOS provides several methods to list services running on a server. Here are the most common methods:
Method 1: Using Systemctl
Systemctl is a command-line tool that is used to manage services in CentOS. To list all the services running on a CentOS server, use the following command:
systemctl list-unit-files --type=serviceThis command will display a list of all the services installed on the server, along with their current status (enabled or disabled).
To list only the active services, use the following command:
systemctl list-units --type=service --state=runningThis command will display a list of all the services that are currently running on the server.
Method 2: Using Service Command
The Service command is another tool that can be used to manage services in CentOS. To list all the services running on a CentOS server, use the following command:
service --status-allThis command will display a list of all the services installed on the server, along with their current status (running or stopped).
Conclusion
In this article, we discussed how to list services in CentOS. We provided examples that illustrate the process using two different methods: Systemctl and Service command. By using these methods, system administrators can easily monitor and manage the services running on their CentOS servers.
It is essential to keep track of the services running on a CentOS server to ensure that they are performing their intended functions and not causing any issues. Proper management of services can help to prevent downtime and ensure that the server is running optimally.
