What is eAccelerator ?

is a free open-source PHP accelerator, optimizer, and dynamic content cache. 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.

When i heard that then in my mind why didn’t try to install it on my blog server, i feel that my blog performance was not fast enough and i think eaccelerator maybe the solution for it.

I assume you have already installed php on your server and checked your php version

root@monitor-ubuntu:~# php -v

PHP 5.2.4-2ubuntu5.5 with Suhosin-Patch 0.9.6.2 (cli) (built: Feb 11 2009 20:09:52)

or you can checked it on your phpinfo, just create a file named test.php then add this

<? phpinfo(); ?>

then checked it on your browser http://localhost/test.php

Prerequisites

The installation of eAccelerator on Ubuntu 8.04 will require that several program packages be installed on your system.  php5-dev is required to get the program phpize.  make is required for the program make

 # install php5-dev
 # install make

Installation

get the latest eaccelarator source code on http://eaccelerator.net/
# wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.tar.bz2
# tar xvjf eaccelerator-0.9.5.3.tar.bz2
# cd eaccelerator-0.9.5.3
# phpize
# ./configure --enable-eaccelerator=shared
# make
# make install
Installing shared extensions:     /usr/lib/php5/20060613+lfs/
Now  you need to edit /etc/php5/apache2/php.ini and add the following line 
at the beginning of the file after the [PHP] tag:
[PHP]

; 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+lfs/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/control.php"
NOTE: If you install Zend Optimizer and/or ionCube Loader you should be sure that 
ionCube loads before Zend Optimizer and eAccelerator installs before both for proper operation 
of all three extensions.

Create and change permissions of the eAccelerator cache directory

# mkdir -p /var/cache/eaccelerator
# chmod 0777 /var/cache/eaccelerator

Control panel

eAccelerator provides a "control panel" of sorts that is useful to see what pages are being cached and usage of shared memory. To install the control panel, first copy file control.php into the web server document root:
# cd /root/eaccelerator-0.9.5.3
# cp control.php /var/www/eaccelerator/

Edit control.php to change the $user and $pw settings to a user name and password of your choosing. 

Don’t leave them as the default or attackers will be able to disrupt the cache.

View the control panel at http://your-server-url/control.php

Note: if you rename or move control.php you must update the eaccelerator.allowed_admin_path setting in php.ini

Restart Apache

# /etc/init.d/apache2 restart

But strange thing happen to my server, when i try to checked the php version. 

eaccelerator hasn't installed yet

# php -v

then i restart the apache
# /etc/init.d/apache2 restart

okay it is changes then i try to checked the phpinfo on my web but eAccelerator hasn't 
been added yet
eaccel11
Hmm, strange it is because the phpmyadmin are using Loaded 
Configuration File = /etc/php5/apache2/php.ini.
I try to create soft symlink on /etc/php5/, i changes the /etc/php5/apache 
to different name let say 
/etc/php5/apache_old,
then i create sysmlink for /etc/php5/cli
# ln -s /etc/php5/cli apache
# ls -al

total 20 

drwxr-xr-x 5 root root 4096 2009-04-01 17:55 . 

drwxr-xr-x 21 root root 4096 2008-12-22 12:24 .. 

lrwxrwxrwx 1 root root 13 2009-04-01 17:55 apache -> /etc/php5/cli 

drwxr-xr-x 2 root root 4096 2009-04-01 15:32 apache_old 

drwxr-xr-x 2 root root 4096 2009-04-01 15:35 cli 

drwxr-xr-x 2 root root 4096 2009-03-12 15:27 conf.d

Then i restart the apache
# /etc/init.d/apache2 restart
checked the phpinfo files on the web, it is changes
eaccel2
Okay is it is strange, i am curious what happen if i delete yhe symlink and changes back 
the /etc/php5/apache_old to /etc/php5/apache
# rm /etc/php5/apache
# mv /etc/php5/apache_old /etc/php5/apache
# ls -al
total 20
drwxr-xr-x   5 root root 4096 2009-04-01 16:42 .

drwxr-xr-x   2 root root 4096 2009-03-12 15:27 conf.d
Then i restart the apache
# /etc/init.d/apache2 restart
 Both phpinfo and php -v show the eAccelerator

Okay i don't know it is because of cache or something but it is installed in the end 🙂
