Here is a small, incomprehensive list of tips and tricks to configure your LEMP system (Linux, nginx, MySQL, PHP-FPM) for maximum performance. These tricks work for me, but your mileage may vary. Do not implement them all at once, but one by one and check what effect the modification has on your system's performance. falko Sun, 23 Sep 2012 09:25:26 GMT http://www.howtoforge.com/dns_cache_with_djbdns Building a local DNS cache will speed up your internet connection since the time for the translation job (converting domain names into IP addresses) will become negligible with the assumption that the DNS cache gets the information from the parent DNS. falko Mon, 07 May 2007 09:12:19 GMT http://www.howtoforge.com/how-to-patch-bind-to-avoid-cache-poisoning-debian-etch Dan Kaminsky earlier this month announced a massive, multi-vendor issue with DNS that could allow attackers to compromise any name server - clients, too. These two articles explain how you can fix a BIND9 nameserver on Debian Etch and Fedora/CentOS so that it is not vulnerable anymore to DNS cache poisoning. falko Tue, 29 Jul 2008 09:55:44 GMT http://www.howtoforge.com/how-to-set-up-a-caching-reverse-proxy-with-squid-2.6-on-debian-etch This article explains how you can set up a caching reverse proxy with Squid 2.6 in front of your web server on Debian Etch. If you have a high-traffic dynamic web site that generates lots of database queries on each request, you can decrease the server load dramatically by caching your content for a few minutes or more (that depends on how often you update your content). falko Sun, 28 Dec 2008 10:57:37 GMT http://www.howtoforge.com/how-to-speed-up-drupal-7.7-with-boost-and-nginx-debian-squeeze This tutorial shows how you can speed up your Drupal 7.7 installation on a LAMP stack (Debian Squeeze) with the help of Boost and nginx. Boost provides static page caching for Drupal enabling a very significant performance and scalability boost for sites that receive mostly anonymous traffic. Boost makes sure that your logged-in users always get fresh content by not caching pages for logged-in users. In a first step I will show how to make your site faster by enabling Boost on a normal LAMP stack (Apache2, PHP, MySQL), and in a second step I explain how to make your site even faster by using nginx as a reverse proxy sitting in front of Apache and delivering the static HTML pages cached by Boost. nginx delivers static files a lot of faster than Apache and us falko Sun, 21 Aug 2011 18:28:51 GMT http://www.howtoforge.com/installing-memcached-and-the-php5-memcache-module-on-debian-etch-apache2 This guide explains how to install memcached and the PHP5 memcache module on a Debian Etch system with Apache2. memcached is a daemon that can store objects in the system's memory (e.g. results of database queries) which can speed up your web site tremendously. You can use memcached over a network (i.e., install your web application on one server and memcached on another server), but usually you install both on one server to avoid the networking overhead. falko Thu, 11 Sep 2008 11:11:06 GMT http://www.howtoforge.com/make-browsers-cache-static-files-with-mod_expires-on-apache2-debian-squeeze This tutorial explains how you can configure Apache2 to set the Expires HTTP header and the max-age directive of the Cache-Control HTTP header of static files (such as images, CSS and Javascript files) to a date in the future so that these files will be cached by your visitors' browsers. This saves bandwidth and makes your web site appear faster (if a user visits your site for a second time, static files will be fetched from the browser cache). This tutorial was written for Debian Squeeze. falko Thu, 10 Mar 2011 11:52:33 GMT http://www.howtoforge.com/running-wordpress-on-nginx-lemp-on-debian-squeeze-ubuntu-11.04 This tutorial shows how you can install and run a WordPress blog on a Debian Squeeze or Ubuntu 11.04 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). In addition to that I will also show you how you can use the WordPress plugins WP Super Cache and W3 Total Cache with nginx. nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files. falko Thu, 01 Sep 2011 08:16:52 GMT http://www.howtoforge.com/zentyal-as-a-gateway-the-perfect-setup Zentyal is a Linux Small Business Server, it lets you manage all your network services through one single platform. It's a Network Gateway, as well as an Infrastructure, UTM (Unified Threat Manager), Office and Communications Server. All these features are fully integrated and easy to configure, it truly helps to save system administrators time. In this tutorial you will see how to set up a Zentyal Server to act as a gateway in a very common scenario. Zentyal will provide basic network infrastructure, load balancing between two Internet providers, firewall and HTTP proxy caching and content filtering. falko Thu, 26 May 2011 10:47:43 GMT
