一、memcached 的编译安装

准备:

Memcached下载地址：http://www.danga.com/memcached/

libevent下载地址: http://monkey.org/~provos/libevent/

安装步骤:

1. 下载libevent & memcached 源码包

libevent-1.3.tar.gz

memcached-1.2.2.tar.gz

2. 解压缩 libevent-1.3.tar.gz ，编译安装

# tar zxvf libevent-1.3.tar.gz

# cd libevent-1.3

# ./configure --prefix=/usr/local/libevent

# make ; make install

3. 解压缩 memcached-1.2.2.tar.gz, 编译安装

# tar zxvf memcached-1.2.2.tar.gz

# cd memcached-1.2.2

# ./configure --prefix=/usr/local/memchached --with-libevent=/usr/local/libevent

# make;make install

4. 作软连接，否则运行memcached的时候将找不到libevent模块

# ln -s /usr/local/libevent/lib/libevent-1.3.so.1 /usr/lib

5.启动memcached

# /usr/local/memcached/bin/memcached -d -m 256 -p 11211 -u root

OK ！！！ 搞定！ ^^

二、php的memcached模块

# tar vxzf memcache-1.5.tgz

# cd memcache-1.5

# /usr/local/php/bin/phpize

# ./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir

# make

# make install

安装完后会有类似这样的提示：

Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/

把这个记住，然后修改php.ini，把

extension_dir = "./"

修改为

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20050922/"

并添加一行

extension=memcache.so

3、测试脚本

自己写一个PHP程序测试一下吧

<?php

$memcache = new Memcache; //创建一个memcache对象

$memcache->connect('localhost', 11211) or die ("Could not connect"); //连接Memcached服务器

$memcache->set('key', 'test'); //设置一个变量到内存中，名称是key 值是test

$get_value = $memcache->get('key'); //从内存中取出key的值

echo $get_value;

?>
