Memcache是一个开源项目,它是一个高性能的分布式的内存对象缓存系统,通过在内存里维护一个统一的巨大的Hash表,能够用来存储各种格式的数据。
1: 还是下载
Memcache是用C编写的,要用到C的libevent来处理接口
点击下载memcached-1.4.0.tar.gz
下载libevent-2.0.13-stable.tar.gz
下载memcache-3.0.6.tgz
我下载到了/root/Downloads
2:解压编译
a:先安装libevent
- #cd /Downloads
- #tar zvxf libevent-2.0.13-stable.tar.gz
- #cd libevent-2.0.13-stable
- #./configure –prefix=/usr
- #make
- #make install
查看下安装是否成功
- # ls -al /usr/lib | grep libevent

- #cd ..
- #tar zxvf memcached-1.4.0.tar.gz
- #cd memcached-1.4.0
- # ./configure –with-libevent=/usr
- # make
- # make install
c. 安装memcache
- #cd ..
- #tar vxzf memcache-3.0.6.tgz
- #cd memcache-3.0.6
- #/usr/local/php/bin/phpize
- #./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
- #make
- #make install
- #gvim /etc/php5/apache2/php.ini
修改php.ini中的extension_dir = “./”
- extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/”
- extension=memcache.so
3: 启动和关闭
#/usr/local/bin/memcached -d -m 128 -u root -l 127.0.0.1 -p 11211 -c 256 -P /var/temp/memcached.pid
#kill `cat /var/temp/memcached.pid` 或者#killall memcached
重启apache
sudo /etc/init.d/apche2 restart
4:测试
< ?php
$mem = new Memcache;
$mem->connect(“127.0.0.1″, 11211);
$mem->set(‘key’, ‘This is a test!’, 0, 60);
$val = $mem->get(‘key’);
echo $val;
?>
5: Ubuntu/debian 。
直接sudo
sudo apt-get install memcached
启动
memcached -d -m 128 -p 11211 -u root -l 127.0.0.1
太轻松了。。。
