linux 配置memcached以及php的memcache扩展

1、安装libevent（libevent-2.0.22-stable.tar.gz）​

memcached依赖libevent包

libevent 是一个用C语言编写的、轻量级的开源高性能网络库​

tar zxvf libevent-2.0.22-stable.tar.gz

cd libevent-2.0.22

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

make​

make install

2、安装memcached（memcached-1.4.29.tar.gz）​

tar zxvf memcached-1.4.29.tar.gz

cd memcached-1.4.29

./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent/

make​ 

make install

启动memcached：memcached -d -u root -m 64 -p 11211 -l 10.251.244.32

表示占用64M内存，端口11211，ip为10.251.244.32

3、安装php的memcache扩展（memcache-2.2.7.tgz）

tar zxvf memcache-2.2.7.tgz

cd memcache-2.2.7

/usr/local/php/bin/phpize​

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

make

make install

安装完显示：Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/

则修改php配置文件：

vim /usr/local/php/etc/php.ini

添加如下：

​extension = /usr/local/php/lib/php/extensions/no-debug-zts-20131226/memcache.so

重启apache​

/usr/local/apache/bin/apachectl restart
