Setting up a PHP/MySQL/Apache2 environment on Debian is really easy. I’ll walk through a quick setup and optimization process. I’ve optimized it for a 1.5Gb to 2GB RAM machine with reasonable load. apt-get install apache2 php5 mysql-server-5.0 mysql-client-5.0 libapache2-mod-php5 php5-mysql php5-curl php5-cli php5-dev make gcc libc6-dev automake

Now download eaccelerator from http://eaccelerator.net tar -xjf eaccelerator.tar.bz2 phpize ./configure make sudo make install

Edit /etc/php5/apache2/php.ini and add the following at the bottom: extension=”eaccelerator.so” eaccelerator.shm_size=”64″ eaccelerator.cache_dir=”/tmp/eaccellerator” eaccelerator.enable=”1″ eaccelerator.optimizer=”1″ eaccelerator.check_mtime=”1″ eaccelerator.debug=”0″ eaccelerator.filter=”” eaccelerator.shm_max=”0″ eaccelerator.shm_ttl=”0″ eaccelerator.shm_prune_period=”0″ eaccelerator.shm_only=”0″ eaccelerator.compress=”1″ eaccelerator.compress_level=”9″

1. * Fine Tuning # key_buffer = 64M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 8 #max_connections = 100 #table_cache = 64 #thread_concurrency = 10 #
2. * Query Cache Configuration # query_cache_limit = 4M query_cache_size = 64M

Restart services: /etc/init.d/apache2 restart /etc/init.d/mysql restart
