Configuring to use the RHEL Repository on CentOS 8 is very simple, and during installation, REMI, which includes the PHP package to be used on the web server, is also installed.

Practical Apache Notes

For current production servers, treat this article as a conceptual reference rather than a copy-and-paste deployment recipe. Confirm the Linux distribution, Apache version, virtual-host layout, firewall rules, TLS certificate path, and backup policy before changing a live server. If the server hosts multiple sites, test configuration changes with a syntax check and reload the service only after verifying that the new configuration does not break existing domains.

Verification Checklist

After editing Apache configuration, run a syntax check, confirm that the expected virtual host answers on the correct domain, and review the error log before assuming the change is complete. If HTTPS is involved, also verify the certificate chain, renewal schedule, and redirect behavior from HTTP to HTTPS. These checks reduce downtime and make the older setup notes safer to apply in a modern hosting environment.
