eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution.
eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times." - eaccelerator.net eAccelerator Homepage
Step-By-Step Command Line Installation
Change directory to home/user directory
Make sure you are in your own user directory, to do this use something like the following:
cd /usr/home/username
Download and extract file
Download and extract version 0.9.5.3 (this is the version that supports php commands required by Moodle and w3 Total Cache)....
wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.tar.bz2 tar xvf eaccelerator-0.9.5.3.tar.bz2 cd eaccelerator-0.9.5.3/
Build and install
sudo phpize
- The following step will work on servers that have a single PHP install. For those with more than one version of PHP see notes on http://eaccelerator.net/wiki/InstallFromSource regarding having php in path, export path if required - This could affect the "--with-php-config" line below)
sudo ./configure --with-php-config=/usr/bin/php-config --with-eaccelerator-shared-memory --enable-eaccelerator=shared sudo make clean sudo make sudo make test sudo make install
Check install location
Check the install area by changing directories:
cd / cd usr/lib/php5/
In this directory you should see a folder named like a date string - eg... "20060613". Remember the folder name, you may need to use this to point to the eaccelerator.so file in the configuration options below.
Add configuration options for eAccelerator to php.ini
cd / cd etc/php5/apache2 sudo nano php.ini
Add to end of php.ini file
Add the following to end of php.ini file (changing folder name appropriately):
; eAccelerator configuration ; Note that eAccelerator may also be installed as a PHP extension or as a zend_extension ; If you are using a thread safe build of PHP you must use ; zend_extension_ts instead of zend_extension ;extension = "/usr/lib/php5/20060613+lfs/eaccelerator.so" zend_extension = "/usr/lib/php5/20060613/eaccelerator.so" eaccelerator.shm_size = "16" eaccelerator.cache_dir = "/var/cache/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" eaccelerator.allowed_admin_path = "/var/www/eaccelerator"
Create cache directory
The next very important step is creating the cache directory that you configured in the previous step. The default value is /tmp/eaccelerator It's easy because it's writable to everyone, but it isn't very smart because on a lot of systems this directory is cleaned on reboot. A better place would be /var/cache/eaccelerator. Create the directory and make sure it's writable for the user eAccelerator runs under (usually the user which you webserver runs as).
A safe bet is making it world writable. A safer and cleaner way would be to change the owner of the directory to the same user PHP runs as (most of the time the same user as Apache or Lighttpd) and set 0644 permissions.
mkdir /tmp/eaccelerator chmod 0777 /tmp/eaccelerator
Restart Apache
Restart Apache by:
sudo /etc/init.d/apache2 restart
