How to Kill Processes on a Fedora 16 Server

In this short guide, we will delve into the process of terminating processes on a Fedora 16 server.

This tutorial is designed for those who have already installed Fedora 16 and are attempting to install MySQL using the yum command. However, if you’ve accidentally canceled it without using the proper command, you’ll need to terminate the process.

This guide will walk you through the steps to accomplish this, providing you with valuable insights into managing processes on your Fedora server. For a deeper understanding of various web servers, you can explore our guide on web servers.

Identifying the Process ID

The first step in terminating a process is to identify the process ID. This can be done using the following command:

ps -ef | grep yum

The output of this command will look something like this:

root 1715 1167 2 17:21 pts/0 00:00:01 /usr/bin/python /usr/bin/yum install mysql
root 1723 1167 0 17:21 pts/0 00:00:00 grep --color=auto yum

Understanding the Kill Command

Before proceeding to terminate the process, it’s important to understand the kill command. You can access the manual for the kill command using the following command:

man kill

The manual provides a detailed explanation of the kill command:

NAME
 kill - terminate a process
SYNOPSIS
 kill [-s signal|-p] [-q sigval] [-a] [--] pid...
 kill -l [signal]

Terminating the Process

Now that you have identified the process ID and understood the kill command, you can proceed to terminate the process. For example, to kill the process with ID 1715, you would use the following command:

kill -9 1715

Verifying the Process Termination

After terminating the process, it’s important to verify whether the process has been successfully terminated or is still running. This can be done using the same command used to identify the process ID:

ps -ef | grep yum

The output should now look something like this:

root 1726 1167 0 17:22 pts/0 00:00:00 grep --color=auto yum
[4]- Killed yum install mysql

This indicates that the process has been successfully terminated.
