What does it do?
It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated.

How to install eaccelerator?

  • Download the eaccelerator-0.9.5.3 at http://www.eaccelerator.net/
  • unzip the file under temporary directory, unzipped/ , for example.
  • You need php5-dev pack first in order to use "phpize"

    apt-get install php5-dev

  • Once it is done, phpize will be installed in /usr/bin/phpize .
  • execute the below commands at the command prompt unzipped/ .
      # export PHP_PREFIX="/usr"
      # $PHP_PREFIX/bin/phpize
      # ./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
      # make
    

  • This will generate "eaccelerator.so" under ./unzipped/modules directory.
  • run

    make install

  • This will copy eaccelerator.so under the /usr/lib/php5 directory. Im my case, it was installed under 20060613+lfs.

    /usr/lib/php5/20060613+lfs/eaccelerator.so

  • Then, copy unzipped/eaccelerator.ini file to /etc/php5/conf.d directory.

    cp unzipped/eaccerlerator.ini /etc/php5/conf.d/eaccelorator.ini

  • Caution : /etc/php5/conf.d directory was available since php was configured with --with-config-file-scan-dir=/etc/php5/conf.d option. If you don't have the directory /etc/php5/conf.d, then copy the below (the content of eaccelerator.ini) in your php.ini file.
      zend_extension="/usr/lib/php5/20060613+lfs/eaccelerator.so" // You need to change this according to your seeting
      eaccelerator.shm_size="64"
      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="3600"
      eaccelerator.shm_prune_period="0"
      eaccelerator.shm_only="0"
      eaccelerator.compress="1"
      eaccelerator.compress_level="9
      eaccelerator.admin.name="yourusername"
      eaccelerator.admin.password="yourpassword"
    

  • in php.ini file, put the below line around the extension config lines.

    extension=eaccelerator.so

  • Create cache directory under /tmp directory.
     
     mkdir /tmp/eaccelerator
     chown www(or whatever) /tmp/eaccelerator
     chmod 0700 /tmp/eaccelerator
    

  • restart apache

    /etc/init.d/apache2 restart

  • Make it sure that the module (.so) was properly installed by looking at phpinfo(); with an web page. The below or similar message will appear in phpinfo(); page.
      This program makes use of the Zend Scripting Language Engine:

  • phpinfo()?
    make a file phpinfo.php under htdocs (or html) directory (something like /var/www), then put the below lines;
      <?php
        phpinfo
    ();
      
    ?>

  • Then, view this page with a web browser with http://localhost/phpinfo.php URL.
