Updated to Eaccelerator 0.9.3 Final Release

Eaccelerator is a further development from mmcache PHP Accelerator & Encoder. It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated.

The instructions in this How-To is a bit different to the official one, because the directories are a bit different - I couldn't get this to work using the instructions from the official guide itself. I also point to the module file in a different directory in php.ini - the default one in the official instructions didn't work for me.

Follow the instructions to install or to upgrade from mmcache.

Installation:

UPGRADING:

1) To upgrade eaccelerator:

Just download the NEW version of eaccelerator and recompile - same instructions as installating.

NOTE the CHANGES to the directory path in php.ini

2) To upgrade PHP versions:

You need to DELETE the eaccelerator directory that has been compiled, re-untar the eaccelerator gzip file and RE-INSTALL and recompile eaccelerator for every NEW version of PHP.

1) Login as root in SSH

2) Run the following commands in the following order:

cd /

mkdir ea

cd ea

wget http://kent.dl.sourceforge.net/sourc...r-0.9.3.tar.gz


tar xvzf eaccelerator-0.9.3.tar.gz

cd eaccelerator-0.9.3

export PHP_PREFIX="/usr"

$PHP_PREFIX/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config

make

make install

3) Edit php.ini - usually it's /etc/php.ini or /usr/local/lib/php.ini

;Windows Extensions

Above this, comment out or remove the PHPA or mmcache lines if you have them. Replace them with this:

To install as a ZEND extension:

zend_extension="/ea/eaccelerator-0.9.3/modules/eaccelerator.so"
eaccelerator.shm_size="16"
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="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

OR to install as a PHP extension:

extension="/ea/eaccelerator-0.9.3/modules/eaccelerator.so"
eaccelerator.shm_size="16"
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="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

4) Create the cache directory by doing the following at the command line

mkdir /tmp/eaccelerator

chmod 0777 /tmp/eaccelerator


5) Restart Apache

service httpd restart

Done!
