Lesson-35 zookeeper 简单实用

一片不错的博客
这个 zookeeper 会监听 本身的 2181 接口 和 8080 接口 所以在出现问题的时候可以去检查 8080 端口是否已经被占用

单节点的时，Mode会显示为standalone
在多节点的时候 我们可以看到主是leader，从是follower

开启和检测 zkserver 服务

Start ZooKeeper

Go to where you installed ZooKeeper:

$ cd ~/opt/zookeeper

Run without server administration script arguments to see available options:

$ bin/zkServer.sh
JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Usage: bin/zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd}

Start ZooKeeper:

$ bin/zkServer.sh start

Check ZooKeeper is Running Correctly

Telnet to the ZooKeeper port and issue one of ZooKeeper’s four letter words, you should see similar output:

$ telnet localhost 2181

开启 zookeeper 命令行

~ /home/conan/toolkit/zookeeper345/bin/zkCli.sh -server 192.168.1.201:2181
