Kafka启动：(根据自身路径更改)

/usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties

Zookeeper启动：(根据自身路径更改)

/usr/local/zookeeper/bin/zkServer.sh start

进入客户端的命令：{zookeeper目录}/bin/zkCli.sh

/usr/local/zookeeper/bin/zkCli.sh

以下是几个zookeeper客户端用的命令，不只kafka，其他任何注册到zookeeper的服务都可以使用这些命令。

1、ls

ls会显示该节点下的子节点信息

比如：ls /

[zk: localhost:2181(CONNECTED) 1] ls /

[dubbo, log_dir_event_notification, isr_change_notification, zookeeper, admin, consumers, cluster, config, latest_producer_id_block, controller, brokers, controller_epoch]

#显示zookeeper根目录下的子节点，其中kafka的broker在zookeeper根目录注册了brokers节点

比如：ls /brokers/topics/lockcar_loction/partitions

[zk: localhost:2181(CONNECTED) 2] ls /brokers/topics/lockcar_loction/partitions

[1, 0]

#显示lockcar_loction这个topic下的partitions的子节点

2、get

get命令会显示该节点的节点数据内容和属性信息

比如：get /brokers/topics/lockcar_loction

[zk: localhost:2181(CONNECTED) 2] get /brokers/topics/lockcar_loction

{"version":1,"partitions":{"1":[1],"0":[3]}}

cZxid = 0x5000000cf

ctime = Wed Apr 08 09:12:12 CST 2020

mZxid = 0x5000000cf

mtime = Wed Apr 08 09:12:12 CST 2020

pZxid = 0x5000000d2

cversion = 1

dataVersion = 0

aclVersion = 0

ephemeralOwner = 0x0

dataLength = 44

numChildren = 1

#显示lockcar_loction这个topic的节点数据内容和属性信息。

#第一行大括号里面就是节点的数据内容，创建topic时候的定义的topic级别配置会被记录在这里

3、ls2

ls2命令会显示该节点的子节点信息和属性信息

比如：ls2 /brokers/topics/lockcar_loction

[zk: localhost:2181(CONNECTED) 4] ls2 /brokers/topics/lockcar_loction

[partitions]

cZxid = 0x5000000cf

ctime = Wed Apr 08 09:12:12 CST 2020

mZxid = 0x5000000cf

mtime = Wed Apr 08 09:12:12 CST 2020

pZxid = 0x5000000d2

cversion = 1

dataVersion = 0

aclVersion = 0

ephemeralOwner = 0x0

dataLength = 44

numChildren = 1

#显示lockcar_loction这个topic的子节点和属性信息。

#第一行中括号里的是子节点。
