一、zookeeper集群启动

### --- zookeeper集群启动

~~~     # 在三台Linux上启动Zookeeper
[root@hadoop01 ~]# zkServer.sh start
[root@hadoop02 ~]# zkServer.sh start
[root@hadoop03 ~]# zkServer.sh start

~~~     # 在三台Linux上查看Zookeeper的状态

[root@hadoop01 ~]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/yanqi/servers/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: follower
[root@hadoop02 ~]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/yanqi/servers/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: follower
[root@hadoop03 ~]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/yanqi/servers/zookeeper-3.4.14/bin/../conf/zoo.cfg
Mode: leader

二、kafka集群启动

### --- 启动kafka集群：前台启动

[root@hadoop01 ~]# kafka-server-start.sh /opt/yanqi/servers/kafka_2.12/config/server.properties
~~~     # Hadoop01节点的Cluster Id：
INFO Cluster ID = 5CZTD5JMTpuw9mjgpTVimQ (kafka.server.KafkaServer)

~~~     # Hadoop02节点的Cluster Id：
root@hadoop02 ~]# kafka-server-start.sh /opt/yanqi/servers/kafka_2.12/config/server.properties
INFO Cluster ID = 5CZTD5JMTpuw9mjgpTVimQ (kafka.server.KafkaServer)

~~~     # Hadoop03节点的Cluster Id：
root@hadoop03 ~]# kafka-server-start.sh /opt/yanqi/servers/kafka_2.12/config/server.properties
INFO Cluster ID = 5CZTD5JMTpuw9mjgpTVimQ (kafka.server.KafkaServer) 

### --- 启动kafka集群：后台启动

~~~     # 所有节点启动zookeeper和kafka
[root@hadoop01 ~]# zkServer.sh start
[root@hadoop01 ~]# kafka-server-start.sh -daemon /opt/yanqi/servers/kafka_2.12/config/server.properties

### --- 验证kafka集群

[root@hadoop01 ~]# zkCli.sh
[zk: localhost:2181(CONNECTED) 6] get /myKafka/cluster/id
{"version":"1","id":"5CZTD5JMTpuw9mjgpTVimQ"}
[root@hadoop02 ~]# zkCli.sh
[zk: localhost:2181(CONNECTED) 6] get /myKafka/cluster/id
{"version":"1","id":"5CZTD5JMTpuw9mjgpTVimQ"}
[root@hadoop03 ~]# zkCli.sh
[zk: localhost:2181(CONNECTED) 6] get /myKafka/cluster/id
{"version":"1","id":"5CZTD5JMTpuw9mjgpTVimQ"}

~~~     # 登录zookeeper客户端，查看kafka集群信息

[root@hadoop01 ~]# zkCli.sh 
[zk: localhost:2181(CONNECTED) 1] ls /myKafka/brokers/ids
[0, 1, 2]

# 查看每个Broker的信息：Hadoop01节点在Zookeeper上的信息：
[zk: localhost:2181(CONNECTED) 2] get /myKafka/brokers/ids/0
{"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://hadoop01:9092"],"jmx_port":-1,"host":"hadoop01","timestamp":"1632506889514","port":9092,"version":4}
cZxid = 0x100000026

~~~     # 查看每个Broker的信息：Hadoop02节点在Zookeeper上的信息：

[zk: localhost:2181(CONNECTED) 3] get /myKafka/brokers/ids/1 
{"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://hadoop02:9092"],"jmx_port":-1,"host":"hadoop02","timestamp":"1632506894168","port":9092,"version":4}
cZxid = 0x10000002f

~~~     # 查看每个Broker的信息：Hadoop03节点在Zookeeper上的信息：

[zk: localhost:2181(CONNECTED) 4] get /myKafka/brokers/ids/2
{"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://hadoop03:9092"],"jmx_port":-1,"host":"hadoop03","timestamp":"1632506892547","port":9092,"version":4}
cZxid = 0x10000002b

一、KafkaEagle启动

### --- 启动zookeeper和kafka

~~~     # 所有节点启动zookeeper和kafka
[root@hadoop01 ~]# zkServer.sh start
[root@hadoop01 ~]# kafka-server-start.sh -daemon /opt/yanqi/servers/kafka_2.12/config/server.properties

### --- 启动KafkaEagle

~~~     # 启动kafka-eagle
[root@hadoop01 ~]# ke.sh start
~~~     # 提示我们登陆地址和账号密码
