centerOS 安装kafka

step1、配置java环境，在挂网下载kafka_2.12-2.7.0
step2、

tar -zxvf kafka_2.12-2.7.0.tgz -C /usr/src/
   chown -R root:root /usr/src/kafka_2.12-2.7.0/ #设置属主和属组
   cd /usr/src/kafka_2.12-2.7.0/

step3、修改配置文件

 vim server.properties

 	listeners=PLAINTEXT://127.0.0.1:9092  监听端口
	zookeeper.connect=127.0.0.1:2181  zook的端口
	zookeeper.connection.timeout.ms=60000  ZooKeeper的最大超时时间
vim zookeeper.properties
    clientPort=2181 #监听端口

step4、关闭防火墙

systemctl stop firewalld

step5、启动
5.1、启动zookeeper

[root@localhost config]# cd /usr/kafka
[root@localhost kafka]# ./bin/zookeeper-server-start.sh -daemon ./config/zookeeper.properties
[root@localhost kafka]# netstat -anpt | grep 2181

5.2、启动kafka

[root@localhost kafka]# ./bin/kafka-server-start.sh -daemon ./config/server.properties

5.3、关闭zk

[root@localhost kafka]# ./bin/zookeeper-server-stop.sh ./config/zookeeper.properties 

5.4、关闭kafka

[root@localhost kafka]# ./bin/kafka-server-stop.sh ./config/server.properties 

5.5、创建topic

[root@localhost kafka]# ./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
