1、安装libevent

memcached基于livevent的事件处理，所以首先安装libevent，用yum安装的话版本较低，所以编译安装

#tar zxvf libevent-1.4.13-stable.tar.gz

#cd libevent-1.4.13-stable

#./configure&& make&& make install

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2、安装memcached

#tarzxvf memcached-1.4.5.tar.gz

#./configure

#make && make install

安装完成后，memcached的默认目录为/usr/local/bin/memcached

添加链接库到ld.so.conf

#echo “/usr/local/lib”>>/etc/ld.so.conf

#ldconfig

启动memcached：

/usr/local/bin/memcached –m128 –p 11211 –d –u root –P /var/run/memcached.pid –vv

测试：telnet localhost 11211

关闭memcached： #kill` cat /var/run/memcached.pid`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3、安装memcache的php扩展

首先，打开phpize

#/usr/local/php5/bin/phpize

#tar zxvf memcache-2.2.5.tar.gz

#./configure –eanble-memcache–with-php-config=/usr/local/php5/bin/php-config

#make && makeinstall

然后根据提示，把生成的.so文件加入到php.ini里面
