Memcached用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提供动态、数据库驱动网站的速度。部署步骤见下：  
1.先安装libevent：

tar zxvf libevent-2.0.15-stable.tar.gz 
    cd libevent-2.0.15-stable
    ./configure --prefix=/usr/local/webserver/libevent-2.0.15
    make && make install

2.安装memcached，同时需要在安装中指定libevent的安装位置

zxvf memcached-1.4.13.tar.gz 
    cd memcached-1.4.13
    ./configure --prefix=/usr/local/webserver/memcached-1.4.13 --with-libevent=/usr/local/webserver/libevent-2.0.15/
    make && make install

启动Memcache的服务器端：

/usr/local/webserver/memcached-1.4.13/bin/memcached -d -m 64 -u root -l 192.168.0.200 -p 11211 -c 256 –P /tmp/memcached.pid

3.附：php的memcached扩展的安装：php有两个memcached扩展，一个是memcache，一个是memcached  
1)安装libmemcached库

tar zxvf libmemcached-0.50.tar.tar 
    cd libmemcached-0.50
    ./configure --prefix=/usr/local/webserver/libmemcached --with-memcached
    make
    make install

2)安装php memcached扩展

zxvf memcached-1.0.2.tgz 
    cd memcached-1.0.2
    /usr/local/webserver/php/bin/phpize 
    ./configure --enable-memcached --with-php-config=/usr/local/webserver/php/bin/php-config --with-libmemcached-dir=/usr/local/webserver/libmemcached
    make
    make install

3)在php.ini里添加

vi /usr/local/webserver/php/etc/php.ini 
    extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
    extension = "memcache.so"
    extension = "memcached.so"

再把服务重启一下

vi /etc/ld.so.conf
    /usr/local/webserver/libevent-2.0.15/bin
    /usr/local/webserver/libmemcached/bin
