eAccelerator - PHP accelerator installation 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 at each request, almost entirely. The already pre-compiled code is stored in shared memory and then called directly. In addition, the running time is optimized to accelerate the implementation of the PHP code.

Personal experiences with eAccelerator:

Since we hosted a while ago a little busier side and we had quite a performance problem, a friend of mine gave me the tip to try eAccelerator administrator. At first I was skeptical and was quoted to me the exact loading of the page to search for the installation of eAccelerator have a comparison. The performance increase was in my case, after installing all 89.5%.

For eAccelerator is unfortunately no official packages under the Sources, so we have to download the software to compile by hand. This step, however, is not too difficult:

Prerequisites: Install

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

apt-get install build-essential php5-dev bzip2


eAccelerator download and unzip:

We now get 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 http://bart.eaccelerator.net/source/0.9.6/eaccelerator-0.9.6.tar.bz2

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

tar -xjvf eaccelerator-0.9.6.tar.bz2

eAccelerator and was successfully extracted in / usr / src.

eAccelerator configure and compile:

With the following commands compile / install eAccelerator for our system, we

cd eaccelerator-0.9.6
phpize
./configure
make
make install

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

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

The newly created eaccelerator.ini fill us now with the following standard contents:

extension="eaccelerator.so"
eaccelerator.shm_size="32"
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"

Information about the settings you will Genaure Here

The value "eaccelerator.shm_size defines the maximum amount of memory, which may take eAccelerator and should therefore be carefully adapted.

Thus, the eAccelerator Cache Files may place on our hard drive, we create the folder that we configured in the. Ini file (/ var / cache / eaccelerator) and also awarded the rights to.

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

As a last and final step, we now 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 must control.php only from the directory / usr/src/eaccelerator-0.9.6 be copied to the webserver directory:

cp /usr/src/eaccelerator-0.9.6/control.php /var/www/

Now we edit the file control.php ...

vi /var/www/control.php

... And change the login information that is accessible to those on control.php ("admin" and "eAccelerator" according to replace)

$ User = "admin";
$ Pw = "eAccelerator";

As a concluding step is the control panel nor the necessary permission will be granted in order to read data from eAccelerator and to 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 even restart the Apache and the Control Panel can about http://www.mein-server.org/control.php be called.

And this is the eAccelerator control panel then:
