kafka集群搭建

● zk集群事先已准备好
● 上传kafaka压缩包至Linux解压

[[email protected] ~]# tar -zxvf kafka_2.11-0.8.2.2.tgz -C /root/
[[email protected] ~]# cp kafka_2.11-0.8.2.2 ./apps/

● 修改kafka配置

[[email protected] ~]# cd ./apps/kafka_2.11-0.8.2.2/config/
[[email protected] config]# vi server.properties 

broker.id=0  #每台机器必须唯一
host.name=hadoop-01 #可不写
log.dirs=/data/kafka    #注意：这不是日志路径，这是kafka数据保存路径
zookeeper.connect=hadoop-01:2181,hadoop-02:2181,hadoop-03:2181  # zk集群

● 拷贝至每个机器

[[email protected] apps]# scp -r kafka_2.11-0.8.2.2/ hadoop-02:$PWD
[[email protected] apps]# scp -r kafka_2.11-0.8.2.2/ hadoop-03:$PWD

修改这2个属性即可，比如
hadoop-02改为broker.id=1 ，host.name=hadoop-02
hadoop-03改为broker.id=2 ，host.name=hadoop-03

● 启动

#这是以后台的形式启动，如果不需要后台启动，去掉-daemon即可
[[email protected] apps]# ./kafka_2.11-0.8.2.2/bin/kafka-server-start.sh -daemon ./kafka_2.11-0.8.2.2/config/server.properties
