Before we dive into the nitty-gritty details, let us first understand the meaning of Apache server cache. In layman’s terms, it is a temporary storage area that stores frequently accessed web pages, images, and other files to provide quicker access to the users. However, over time, this cache can accumulate and slow down the website’s performance. Hence, it is essential to clear the cache regularly.

This will stop the Apache server.

Step 4: Clear the cache

Now, you can clear the cache by typing the following command:

$ sudo rm -rf /var/cache/httpd/*

This will remove all the files from the Apache server cache.

Step 5: Restart the Apache server
