PhP5 xcache Installation Guide

Xcache is a fast and stable PHP code-level cache that provides an effective buffer layer for servers under high load environments. Buffers similar to eaccelerator and APC are available.

This article describes how to install xcache pai_^ for PHP.

Test Environment setup

I used apache2 + PhP5 in centos5.5 to build a simple test environment. The website root directory is under/var/www/html.

View Current PhP5 Configuration

Before installing xcache, check your PHP configuration, create info. php in the/var/www/html directory, and write the following code:

?

1	touch /var/www/html/info.php

?

123	<?php phpinfo(); ?>

View the phpinfo information in the browser, http: // localhost/info. php

Of course, you still cannot see the xcache installation information.

If you see other caches in the configuration, such as eaccelerator or APC, You need to delete them first:

?

# Deleting an eaccelerator yum remove php-eaccelerator # Delete APCyum remove php-pecl-apc Restart the httpd server/etc/init.d/httpd restart

Start xcache Installation
Because xcache does not have an existing RPM installation package, we need to manually compile this module.

yum install php-devel yum groupinstall 'Development Tools'yum groupinstall 'Development Libraries'# Download the latest xcache and decompress it cd /tmpwget http://xcache.lighttpd.net/pub/Releases/1.3.0/xcache-1.3.0.tar.gz tar xvfz xcache-1.3.0.tar.gz cd xcache-1.3.0 # Use phpize tool to compile xcache phpize ./configure --enable-xcache makemake install# Copy the xcache configuration file to the PHP configuration directory. cp xcache.ini /etc/php.d
