Memcache 高性能分布式内存对象缓存系统
Memcache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,它能够用来存储各种格式的数据,包括图像、视频、文件以及数据库检索的结果等。简单的说就是将数据调用到内存中,然后从内存中读取,从而大大提高读取速度。
下载:http://www.danga.com/memcached/dist/memcached-1.2.2.tar.gz
另外,memcache用到了libevent这个库用于socket的处理,所以还需要安装libevent,libevent的最新版本是libevent-1.3。(如果你的系统已经安装了libevent,可以不用安装)
官网:http://www.monkey.org/~provos/libevent/
下载:http://www.monkey.org/~provos/libevent-1.3.tar.gz
用wget指令直接下载这两个东西.下载回源文件后。
1.先安装libevent。这个东西在配置时需要指定一个安装路径,即./configure –prefix=/usr;然后make;然后make install;
2.再安装memcached,只是需要在配置时需要指定libevent的安装路径即./configure –with-libevent=/usr;然后make;然后make install;
这样就完成了linux下memcache服务器端的安装。详细的方法如下:
1.分别把memcached和libevent下载回来,放到 /tmp 目录下:
# cd /tmp
# wget http://www.3ppt.com/memcached/dist/memcached-1.2.0.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
2.先安装libevent:
# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure –prefix=/usr
# make
# make install
# ls -al /usr/lib | grep libevent
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3

lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3
# cd /tmp
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure –with-libevent=/usr
# make
# make install
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug
tar vxzf memcache-2.2.1.tgz
cd memcache-2.2.1
/usr/local/php/bin/phpize
./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
make
make install
< ?php
$mem = new memcache;
$mem->connect("192.168.0.200 ", 12000);
$mem->set('key', ‘this is a test!', 0, 60);
$val = $mem->get('key');
echo $val;
