MMCache How To on Linux

Turck MMCache is a free open source PHP accelerator, optimizer, encoder and dynamic content cache for PHP. It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated. Also it uses some optimizations to speed up execution of PHP scripts. Turck MMCache typically reduces server load and increases the speed of your PHP code by 1-10 times.

Latest Turck MMcache versions can be downloaded from:
http://sourceforge.net/project/showfiles.php?group_id=69426

Be sure that you have
installed the following packages or recent versions of them:
apache 1.3, mod_php 4.1,
autoconf, automake, libtool, m4

Unpack the file by issuing
the command:
tar xvf
turck-mmcache-2.4.6.tar.bz2 -bzip

Compiling, installing Turck MMCache

export PHP_PREFIX="/usr"
$PHP_PREFIX/bin/phpize
./configure --enable-mmcache=shared
--with-php-config=$PHP_PREFIX/bin/php-config
make
make install

Note: Prefix for cPanel
based servers is /usr

Next, issue the following
commands:

# updatedb
# locate mmcache.so

You will see something
like:

root [/]# locate mmcache.so
/usr/lib/php/extensions/no-debug-non-zts-20020429/mmcache.so
/usr/src/turck-mmcache-2.4.6/modules/mmcache.so
/usr/src/turck-mmcache-2.4.6/.libs/mmcache.so

Then, go to your home
directory and issue the following:

user [/]# vi info.php

Add the following to that
file:
<?php phpinfo(); ?>
and press wq to save and exit

Go to your browser and type
yourdomain.com/info.php
Find the Configuration
File (php.ini) Path and edit that file.
Php.ini can be found under /usr/local/lib/php.ini on
cPanel based servers.

Edit that file (vi /usr/local/lib/php.ini) and search for
zend.
Above the lines:
;zend_optimizer.optimization_level=15
;zend_extension="/usr/local/Zend/lib/ZendOptimizer.so"
add the following:

zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20020429/mmcache.so"
mmcache.shm_size="16"
mmcache.cache_dir="/tmp/mmcache"
mmcache.enable="1"
mmcache.optimizer="1"
mmcache.check_mtime="1"
mmcache.debug="0"
mmcache.filter=""
mmcache.shm_max="0"
mmcache.shm_ttl="0"
mmcache.shm_prune_period="0"
mmcache.shm_only="0"
mmcache.compress="1"

Save the file and exit (wq)
Then issue the following
commands:
mkdir /tmp/mmcache
chmod 0777 /tmp/mmcache
Be sure that your tmp directory has plenty of space.
Restart Apache:
/etc/init.d/httpd restart
Go to your info.php file and search through your browser for mmcach.

NOTICE:
