Overview:
In some rare cases, Apache (also known as httpd) may not be properly installed or may be missing after a fresh cPanel/WHM installation. Without Apache, hosted websites on the server will be inaccessible. This article provides a command to reinstall the Apache web server and all necessary modules to ensure proper functionality.

Symptoms:

• Websites show "Connection Refused" or "Service Unavailable"

• Apache service (httpd) is missing or fails to start

• No Apache-related packages are found on the server

Environment:

• cPanel/WHM Server

• AlmaLinux, Rocky Linux, CentOS (with yum package manager)

• EasyApache 4

Solution:

To reinstall Apache and its required modules, run the following command as the root user:

yum install ea-apache24 ea-apache24-mod_mpm_prefork ea-apache24-mod_cgi ea-apache24-mod_ssl ea-apache24-config-runtime ea-apache24-tools -y --allowerasing

Explanation of Packages:

• ea-apache24: Main Apache 2.4 package provided by EasyApache 4

• ea-apache24-mod_mpm_prefork: Required MPM module for compatibility with some PHP handlers

• ea-apache24-mod_cgi: Enables CGI support

• ea-apache24-mod_ssl: Enables SSL (HTTPS) support

• ea-apache24-config-runtime: Base runtime configuration for Apache

• ea-apache24-tools: Utility tools for Apache management

After Installation:

Once installed:

1. Restart Apache using:

   systemctl restart httpd
   

2. Check Apache Status:

   systemctl status httpd
   

3. Verify Website Accessibility:

   • Open a browser and visit your hosted domains.

   • They should now load properly if DNS and virtual host configs are set correctly.

Additional Notes:

• This solution applies to cPanel servers using EasyApache 4.

• Ensure your server has network access to the cPanel package mirrors.

• If you're using a custom Apache configuration or 3rd-party modules, consider backing up your configuration before reinstalling.
