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;
?>
