PHP Accelerator

If you have running a webserver with many PHP pages I recommend to use a PHP accelerator like eaccelerator. Installation is really easy:

• Download the source
• Unpack the source and change to the unpacked directory
• run “phpize”
• run “./configure”
• run “make”
• run “make install”
• run ‘”mkdir /tmp/eaccelerator”
• run “chmod 0777 /tmp/eaccelerator”
• edit “/etc/php5/apache2/php.ini” (e.g. on Debian Etch)

[eAccelerator]
extension="eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/tmp/eaccelerator/"
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"

• restart apache “/etc/init.d/apache2 restart”

In my example the shm_size has been set to 128 MByte because the server hosts serveral domains with PHP pages.
