Memcached是一个高性能的分布式内存对象缓存系统，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，从而提高动态数据库驱动网站的访问速度。Memcached基于一个存储键/值对的hashmap。其守护进程（daemon ）是用C写的，但是客户端可以用任何语言来编写，并通过memcached协议与守护进程通信。我们这个架构案例使用Memcached来存储用户的session。
我们经常会在负载均衡的环境下遇到Session问题，一般的解决办法有三种：
PHP可以很容易在php.ini配置中将Session存储在Memcached中，来实现Session共享，这样后端服务器有节点down机，用户的访问请求被调度到集群中的其他节点时，用户的会话也不会丢失。
Memcached的安装比较简单。首先Memcached依赖于libevent，所以需要先编译安装libevent，然后编译安装Memcached。后面我们在PHP配置管理中编写php-memcached的模块。同时还需要创建一个管理用户的配置，Memcached包括后面要配置的Nginx和PHP，都要使用www用户进行管理。
首先创建目录结构如下：
[root@SaltMaster1(10.182.88.136)]$~:>mkdir -pv /srv/salt/prod/libevent/files [root@SaltMaster1(10.182.88.136)]$~:>mkdir -pv /srv/salt/prod/memcached/files [root@SaltMaster1(10.182.88.136)]$~:>mkdir -pv /srv/salt/prod/user
启动Memcached需要使用www用户，包括后面我们不熟Nginx和PHP都需要使用到www用户。所以我们把www用户的配置单独放置在user目录下：
[root@SaltMaster1(10.182.88.136)]$~:>more /srv/salt/prod/user/www.sls www-user-group: group.present: - name: www - gid: 1000 user.present: - name: www - fullname: www - shell: /sbin/nologin - uid: 1000 - gid: 1000
后期在需要使用到www用户的地方，将www.sls包含进去即可。
