How to Install eAccelerator

This is my first experience on installing eAccelerator and to my surprise the installation process went very smoothly.

FYI, eAccelerator an open source PHP accelerator, optimized and dynamic content cache. By using eAccelerator, it will increase your PHP script performance by caching those scripts in their compiled state resulting the overhead of compiling is almost completely eliminated.

First of all, download the latest version of eAccelerator from http://eaccelerator.net, the newest version at the time I write this article is eAccelerator 0.9.5.2.

After you download the file, uncompress the file

tar xjvf eaccelerator-0.9.5.2.tar.bz2

You will then have a new directory called eaccelerator-0.9.5.2, go to that directory and execute this command:

Run phpize

phpize

Configure eAccelerator

./configure

After that, don’t forget to build the files

make

You might want to run make test to test it first.

Finally, we install eAccelerator

sudo make install

You process will give you and output that might be similar to this line below:

Installing shared extensions: /usr/lib/php5/20060613+lfs/

Copy the above information to a text file, we gonna need this one later. Now that we’ve finally managed to install eAccelerator, we have to add several settings to the php.ini file.

sudo /etc/php5/apache2/php.ini

And then paste this code at the end of php.ini file.


zend_extension="/usr/lib/php5/20060613+lfs/eaccelerator.so"
eaccelerator.shm_size="0"
eaccelerator.cache_dir="/home/cache/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.allowed_admin_path=""


Note that we used the line we previously saved on the zend_extention parameter. You can also change the value of eaccelerator.cache_dir to any directory you want.

To see wether eAccelerator was successfully installed, create phpinfo file in your site directory. You should see a eAccelerator v0.9.5.2 text somewhere in the phpinfo page.
