一、编译环境的准备
yum install gcc
yum install gcc-c++ libstdc++-devel
yum install zlib-devel
二、源码包准备
wget http://monkey.org/~provos/libevent-1.4.14b-stable.tar.gz
wget http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
三、安装与配置
1、安装libevent
tar zxvf libevent-1.4.14b-stable.tar.gz cd libevent-1.4.14b-stable ./configure --prefix=/usr/local/libevent/ make && make install ln -s /usr/local/libevent/lib/libevent-1.4.so.2 /lib/libevent-1.4.so.22、安装Memcached
tar zxvf memcached-1.4.15.tar.gz cd memcached-1.4.15 ./configure --prefix=/usr/local/memcached/ --with-libevent=/usr/local/libevent/ make && make install
/usr/local/memcached/bin/memcached -d -m 64 -u root -l 127.0.0.100 -p 11211 -c 128 -P /tmp/memcached.pid4、为了方便管理，写个SHELL脚本。

vi /etc/rc.d/init.d/memcached

# memcached: MemCached Daemon

start()
{
echo -n $"Starting memcached: "
daemon $MEMCACHED -u daemon -d -m 64 -l 127.0.0.100 -p 11211 -c 128 -P /tmp/memcached.pid
echo
}
stop()
{
echo -n $"Shutting down memcached: "
killproc memcached
echo
}
MEMCACHED="/usr/local/memcached/bin/memcached"
[ -f $MEMCACHED ] || exit 1
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 3
start
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac
exit 05、添加Memcached开机启动cd /etc/rc.d/init.d/ chmod 777 memcached chkconfig --add memcached chkconfig --level 235 memcached on chkconfig --list | grep memcached6、Memcached使用
service memcached start service memcached stop service memcached restart四、PHP安装Memcache扩展(memcache与memcached扩展二选一即可，建议安装下面的memcached)
[root~] wget -c http://pecl.php.net/get/memcache-3.0.8.tgz [root~] tar -zxvf memcache-3.0.8.tgz [root~] cd memcache-3.0.8 [root~] /usr/local/php/bin/phpize [root~] ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache --with-zlib-dir [root~] make && make install /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/memcache.so [root~] vim /usr/local/php/etc/php.ini extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/memcache.so session.save_handler = memcache session.save_path = "tcp://127.0.0.100:11211" [root~] service php-fpm reload
php5.5+版本的memcache扩展安装方法：
因为php5.5+版本内置了memcache扩展 所以无需下载第三方插件直接 执行如下操作即可 cd /usr/local/php/bin ./pecl install memcache 安装时会提示是否开启session支持，根据需要输入no 或者 yes，安装后路径如下： /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/memcache.so 需要手动配置到php.ini中，增加如下内容，即表示启用memcache扩展： extension=memcache.so补充：PHP的Memcache扩展的安装后发现一个问题，SESSION会出现丢失，这可能是安装Memcached服务端的时候，防火墙没有添加11211端口，修改防火墙规则后，一切正常。
五、PHP memcached 扩展的安装（注意这里是memcached非memcache）
wget https://launchpad.net/libmemcached/1.0/1.0.16/+download/libmemcached-1.0.16.tar.gz tar -zxvf libmemcached-1.0.16.tar.gz cd libmemcached-1.0.16 ./configure --prefix=/usr/local/libmemcached --with-memcached make && make install wget http://pecl.php.net/get/memcached-2.2.0.tgz tar zxvf memcached-2.2.0.tgz cd memcached-2.2.0 /usr/local/php/bin/phpize ./configure --with-php-config=/usr/local/php/bin/php-config make && make install vi /usr/local/php/etc/php.ini 加上extension=memcached.so重起一下服务就可以了。
1、直接修改php.ini配置文件
session.save_handler = memcache session.save_path = "tcp://127.0.0.100:11211"2、利用目录下的 .htaccess 文件
php_value session.save_handler "memcache" php_value session.save_path "tcp://127.0.0.1:11211"3、项目中修改配置
ini_set("session.save_handler", "memcache");
ini_set("session.save_path", "tcp://127.0.0.100:11211");上面只是一些简单的说明，一般来说做分布式是有服务器权限的，所以推荐第一种linux-CentOS6.4安装Memcached+memcached扩展+安装memcache扩展+Memcache同步SESSION的几种方法,布布扣,bubuko.com
