memcached简单使用

• memcached连接， 若linux未安装telnet，需先安装telnet
  • yum -y install telnet.* #安装客户端
  • yum -y install telnet-server # 安装服务器端
  • telnet 127.0.0.1 11211
• stats 命令来输出 Memcached 服务信息。
• Memcached stats items 命令用于显示各个 slab 中 item 的数目和存储时长
  • stats items
  • get age 0 # 显示所有key为age的值

stats items
STAT items:1:number 1
STAT items:1:age 7
STAT items:1:expired_unfetched 0
STAT items:1:evicted_unfetched 0
END
