Linux-查看zookeeper的kafka节点信息

1、第1步：连接
[root@lucky logs]$ cd /home/data/zookeeper-3.4.14/cmd/
[root@lucky cmd]$ ll

-rw-r--r--. 1 test root  115 3月   1 17:35 nohup.out
-rwxrwxrwx. 1 test root  238 2月  20 2014 README.txt
-rwxrwxrwx. 1 test root   46 7月  15 2015 restart.sh
-rwxrwxrwx. 1 test root   85 7月  15 2015 start.sh
-rwxrwxrwx. 1 test root   18 7月  15 2015 stop.sh
-rwxrwxrwx. 1 test root 1937 2月  20 2014 zkCleanup.sh
-rwxrwxrwx. 1 test root 1049 2月  20 2014 zkCli.cmd
-rwxrwxrwx. 1 test root 1534 2月  20 2014 zkCli.sh

-rwxrwxrwx. 1 test root 5755 1月   6 2017 zkServer.sh
-rwxrwxrwx. 1 test root 4534 5月  11 2015 zookeeper.out
[root@lucky cmd]$ ./zkCli.sh -server  localhost:2181
log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender.
Connecting to localhost:2181
Welcome to ZooKeeper!
JLine support is enabled

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]

2、第2步：查看全部
[zk: localhost:2181(CONNECTED) 1] ls /
[isr_change_notification, test, zookeeper, admin, consumers, config, controller, test_safe, brokers, controller_epoch]

3、第3步：查看brokers
[zk: localhost:2181(CONNECTED) 2] ls /brokers
[seqid, topics, ids]

4、第4步：查看ids,#kafka 的broker.id 示例为三个kafka节点的broker.id
[zk: localhost:2181(CONNECTED) 3] ls /brokers/ids
[3, 2, 0]  

5、第5步：查看所有的kafka节点信息是否已经注册到zookeeper上面,#这个0表示第0个节点，看其它kafka节点，要改成1,2，3等
[zk: localhost:2181(CONNECTED) 4] get /brokers/ids/0

[zk: localhost:2181(CONNECTED) 7]

6、第6步：退出
[zk: localhost:2181(CONNECTED) 7] quit
