eAccelerator - PHP accelerator installed in Debian 5 (Lenny) and Ubuntu

eAccelerator - small program with great effect.

eAccelerator is a tool that accelerates the execution of PHP code under Apache. The code is already stored in a compiled state, so the compilation is eliminated almost entirely on each page request. The pre-compiled code is stored in shared memory and then called directly. Furthermore, the runtime is optimized to speed up the execution of PHP code.

Personal experiences with eAccelerator:

There we some time ago a slightly more affluent side hosts and we had quite a performance problem, the administrator gave me a friendly tip eAccelerator try. I was skeptical at first, and wrote down the exact loading of the page to after the installation of eAccelerator to have a comparison. The performance increase was in my case, after installing all 89.5%.

For eAccelerator Unfortunately there are no official packages under the Sources, so we have to download the software manually and compile it. This step, however, is not too difficult:

Prerequisites: Install

So that we can compile eAccelerator for the system, are needed for some packages that are included in "build-essential", we also need the php5-dev package. This we will install the following command:

apt-get install build-essential php5-dev

eAccelerator download and unzip:

Now we grab the latest version of eAccelerator with the manufacturer's site and save it to / usr / src. Currently, the latest version 0.9.5.3.

cd /usr/src
wget get http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.zip

The eAccelerator is now packed in our / usr / src directory. This we will now unpack.

unzip eaccelerator-0.9.5.3.zip

eAccelerator has been successfully extracted in / usr / src.

eAccelerator compile and configure:

Compile with the following commands / we install eAccelerator for our system

cd eaccelerator-0.9.5.3
phpize
./configure
make
make install

Once these steps are completed, we share with our PHP, we would like to use eAccelerator. For this we create a new ini file in our default PHP directory

vi /etc/php5/conf.d/eaccelerator.ini

The eaccelerator.ini we just created is now filled with the following standard contents:

extension="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"

Genaure information about the settings you here is

Thus, the eAccelerator cache files can sit on our hard drive, we create the folder that we configured in the. Ini file (/ var / cache / eaccelerator) and also assign the appropriate rights.

mkdir /var/cache/eaccelerator
chmod 777 /var/cache/eaccelerator

As a last and final step we will start our Apache:

apache2ctl restart

or

/etc/init.d/apache2 restart

eAccelerator control panel to activate

Thanks to Peter for the tip and the description of the Control Panel

The file only needs control.php from the directory / usr/src/eaccelerator-0.9.5.3 be copied to the webserver directory:

cp /usr/src/eaccelerator-0.9.5.3/control.php /var/www/

Now we edit the file control.php ...

vi /var/www/control.php

... And change the login information can be accessed by those on control.php ( "admin" and substitute "eAccelerator" as appropriate)

$ user = "admin";
$ pw = "eAccelerator";

As a concluding step must be granted to the Control Panel or the necessary authorization to read data from eAccelerator and send commands. For this we edit the file eaccelerator.ini ...

vi /etc/php5/conf.d/eaccelerator.ini

... And add to this the following entry

eaccelerator.allowed_admin_path="/var/www/control.php"

Now start Apache, and even the Control Panel can be accessed via http://www.mein-server.org/control.php.
