001_下线zk集群

一、查看都谁用着zookeeper

目前一共两种方式

(1)netstat的TCP/IP的State查看zk连接

sudo netstat -an|egrep "10.0.138.135:2181"|grep "ESTABLISHED"
tcp        0      0 10.0.138.135:2181       10.0.134.180:58119      ESTABLISHED

sudo netstat -an|egrep "10.0.138.135:2181"|grep "TIME_WAIT"
tcp        0      0 10.0.138.135:2181       10.0.134.146:59087      TIME_WAIT

(2)用stat命令查看

echo stat|nc localhost 2181

Zookeeper version: 3.4.9-1757313, built on 08/23/2016 06:50 GMT
Clients:    #这里的Clients连接正好等于"ESTABLISHED"状态的ip
/10.0.136.110:24589[1](queued=0,recved=284422,sent=284479)
/10.0.130.130:21403[1](queued=0,recved=284414,sent=284471)

/10.0.135.125:26141[1](queued=0,recved=284455,sent=284512)

/10.0.134.146:55371[1](queued=0,recved=284476,sent=284533)
/10.0.134.180:58097[1](queued=0,recved=284495,sent=284552)
/10.0.134.146:55413[1](queued=0,recved=284497,sent=284554)

(3)从zookeeper的supervisorctl的日志输出/data/log/zookeeper路径文件running.log可以看出没有session建立进行数据传输了,虽然还有连接在(执行上边的两个步骤看到还有连接)
