How to Install XCache for PHP

[Vinil]

XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduces serverload.

To install download the latest Stable xcache Release

Code: [Select]

cd /usr/local/src/
wget http://xcache.lighttpd.net/pub/Releases/3.0.3/xcache-3.0.3.tar.gz
tar -zxvf xcache-3.0.3.tar.gz
cd xcache-3.0.3

Use phpize command to prepare xcache as a PHP extension for compiling,

phpize

Configure, compile and install xcache

./configure –enable-xcache
make
make install

After successful installation open php.ini and add xcache.so entries.

Code: [Select]

vi /usr/local/lib/php.ini
extension=”xcache.so”

restart Apache webserver.

/etc/init.d/httpd restart

Now verify the xcache by checking the php version from CLI or use an info page

root@server [/]# php -v
