环境准备
环境资源包：
jdk-8u341-linux-x64.tar.gz
kafka_2.12-2.2.0.tgz
zookeeper-3.4.14.tar.gz
| server-id | ip | 状态 |
|---|---|---|
| server1 | 10.206.120.10 | leader |
| server2 | 10.206.120.2 | follower |
| server3 | 10.206.120.3 | follower |
一、安装jdk
因为kafka需要Java环境，所以优先配置jdk环境，若已经配置了java环境，此步骤可以忽略
bash
[root@VM-120-2-centos ~]# tar -xvf jdk-8u341-linux-x64.tar.gz
[root@VM-120-2-centos ~]# mv jdk1.8.0_341/ /usr/local/
#在文件末尾加入以下语句
[root@VM-120-2-centos ~]# vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_341
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib
[root@VM-120-2-centos ~]# source /etc/profile
[root@VM-120-2-centos ~]# java -version
java version "1.8.0_341"
Java(TM) SE Runtime Environment (build 1.8.0_341-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.341-b10, mixed mode)
至此jdk环境配置完成二、zookeeper集群安装
bash
[root@VM-120-2-centos ~]# cd
[root@VM-120-2-centos ~]# tar -xvf zookeeper-3.4.14.tar.gz
[root@VM-120-2-centos ~]# mv zookeeper-3.4.14 /usr/local/zookeeper
[root@VM-120-2-centos ~]# cd /usr/local/zookeeper/conf/
[root@VM-120-2-centos ~]# cp zoo_sample.cfg zoo.cfg
[root@VM-120-2-centos ~]# vim zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataLogDir=/usr/local/zookeeper/logs

server.1= 10.206.120.10:2888:3888
server.2= 10.206.120.2:2888:3888
server.3= 10.206.120.2:2888:3888
[root@VM-120-2-centos ~]# mkdir /usr/local/zookeeper/data
#10.206.120.10服务器上执行
[root@VM-120-2-centos ~]# echo "1" > /usr/local/zookeeper/data/myid
#10.206.120.2服务器上执行
[root@VM-120-2-centos ~]# echo "2" > /usr/local/zookeeper/data/myid
#10.206.120.3服务器上执行
[root@VM-120-2-centos ~]# echo "3" > /usr/local/zookeeper/data/myid
[root@VM-120-2-centos ~]# cd ../bin/
[root@VM-120-2-centos ~]# ./zkServer.sh start
[root@VM-120-2-centos ~]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: leader
[root@VM-120-2-centos ~]# netstat -ntlp
看看端口是否正常启动二、kafka集群安装
bash
[root@VM-120-2-centos ~]# cd
[root@VM-120-2-centos ~]# tar -xvf kafka_2.12-2.2.0.tgz
[root@VM-120-2-centos ~]# mv kafka_2.12-2.2.0 /usr/local/kafka

#查看9092端口是否启动，启动即为正常
[root@VM-120-10-centos bin]# netstat -ntlp
bash
#下面所有命令在kafka的bin目录下执行（笔者是/usr/local/kafka/bin）
#创建topic话题
./kafka-topics.sh --create --bootstrap-server 10.206.120.10:2181,10.206.120.2:2181,10.206.120.3:2181 --replication-factor 3 --topic test --partitions 3
#开启一个生产者
./kafka-console-producer.sh --broker-list 10.206.120.10:2181,10.206.120.2:2181,10.206.120.3:2181 --topic test
#开启一个消费者
./kafka-console-consumer.sh --bootstrap-server 10.206.120.10:2181,10.206.120.2:2181,10.206.120.3:2181 --topic test --from-beginning
#列出所有topic
./kafka-topics.sh --zookeeper 10.206.120.10:2181,10.206.120.2:2181,10.206.120.3:2181 -list
#输出某个topic
./kafka-topics.sh --zookeeper 10.206.120.10:2181,10.206.120.2:2181,10.206.120.3:2181 --delete --topic test

至此集群搭建成功，可以正常使用了
