Nginx vs Apache vs OpenLiteSpeed for WordPress on a VPS
A practical comparison of Nginx, Apache and OpenLiteSpeed for WordPress on a VPS, covering.htaccess support, caching, memory use and ease of setup, with a clear pick for each situation.
Node.js WebSockets behind Nginx, Apache, LiteSpeed or cPanel
Make Socket.IO or ws WebSockets work behind a reverse proxy: upgrade headers for Nginx, Apache and LiteSpeed, timeouts, wss:// over SSL and cPanel limits.
Put a Node.js app behind Nginx, Apache or LiteSpeed (reverse proxy)
Serve a Node.js app on port 80/443 by proxying a domain to it with Nginx, Apache or OpenLiteSpeed, including headers, WebSocket support and testing.
Run PHP-FPM with Apache using proxy_fcgi and mpm_event
Move Apache from mod_php and the prefork MPM to PHP-FPM with mpm_event and proxy_fcgi. Use less memory, serve more visitors and pick a PHP version per virtual host.
Secure Apache with a free Let's Encrypt certificate
Install certbot with its Apache plugin, issue free Let's Encrypt certificates for each virtual host, redirect HTTP to HTTPS and confirm that automatic renewal works.
Set browser caching in Apache with mod_expires and headers
Tell browsers how long to keep your files. Use mod_expires and Cache-Control headers in Apache to cache versioned assets for a year and keep HTML fresh.
Set up Apache virtual hosts for multiple websites
Host several websites on one Apache server with name-based virtual hosts. One config file per domain, its own document root and its own logs, on Ubuntu, Debian, AlmaLinux and Rocky Linux.
Switch Apache MPM to event in cPanel
Compare prefork, worker and event, switch Apache to the event MPM in EasyApache 4, move sites to PHP-FPM first and tune MaxRequestWorkers for your VPS.
Troubleshooting Apache MPM switching: worker vs event vs prefork
Apache loads only one MPM at a time, and switching between prefork, worker and event fails when mod_php, duplicate LoadModule lines or panel rules get in the way. This guide shows how to check, switch and fix it.
Tune Apache MPM settings to stop memory exhaustion
Size Apache's MaxRequestWorkers to the RAM you really have, choose between prefork and event, set ServerLimit and KeepAlive sensibly and spot the MaxRequestWorkers warning in your logs.
Tune Apache settings in WHM Global Configuration
Adjust KeepAlive, Timeout, ServerLimit and MaxRequestWorkers in WHM, and add custom Apache directives with the Include Editor so they survive rebuilds.
Upgrade PHP to a newer version on your VPS
Upgrade a site from PHP 8.1 to 8.3 or 8.4 safely. Install the new PHP-FPM and matching extensions, carry over php.ini changes, switch Nginx or Apache, test, and remove the old version.
Use Apache as a reverse proxy with mod_proxy
Put Apache in front of a Node.js, Python or Docker app with mod_proxy. Set ProxyPass and ProxyPassReverse, keep the original host, proxy WebSockets and serve the app over HTTPS.
