What is the optimal server software for WordPress, XenForo (Forum), Moodle, and MediaWiki?
Hi, I'm just learning how to optimize my droplet. Please feel free to provide advice, links, etc. My droplet operates but varnishstat shows a hitrate average of zero. Cloudflare is showing over 6K+ unique visitors in the past four days. Top shows up to 50% or greater CPU usage every 1/2 hour. My reverse proxy is not working; that is, it shows 127.0.0.1 in XenForo ... but I can use the WordPress plugin login attempts and click reverse proxy and get the correct IP. When the droplet is booting there is an red fail - but I don't know how to read what is failing. After optimizing mysql using mysqltuner.pl then the site pages load very quickly BUT after some time then the pages served are blank. A restart of apache2 fixes this temporarily. These are installed. Apache APC memcached mysql Nginx PHPMyAdmin Varnish How do I check if varnish is even installed properly since varnishstat is showing zero? Should varnish be removed? Do you believe this is the culprit of the blank pages?
