zookeeper
1.三节点执行
tar -zxvf zookeeper-3.4.6.tar.gz -C /usr/local/
2.三节点执行
[root@localhost opt]# cd /usr/local/zookeeper-3.4.6/
[root@localhost zookeeper-3.4.6]# mkdir -p zkdata
[root@localhost zookeeper-3.4.6]# mkdir -p zkdatalog
3.修改配置文件，三节点执行
[root@kafka2 conf]# vi zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10

# sending a request and getting an acknowledgement

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just

4.节点1
[root@localhost zookeeper-3.4.6]# echo '1' > zkdata/myid
节点2
[root@localhost zookeeper-3.4.6]# echo '2' > zkdata/myid
节点3
[root@localhost zookeeper-3.4.6]# echo '1' > zkdata/myid
5.起zookeper进程，三节点执行
[root@kafka1 ~]# cd /usr/local/zookeeper-3.4.6/bin/
[root@kafka1 bin]# ./zkServer.sh start
kafka
6.三节点执行
[root@kafka3 opt]# tar -zxvf kafka_2.11-1.0.0.tgz
[root@kafka1 kafka_2.11-1.0.0]# mkdir -p kdata
7.修改配置文件，三节点执行，其他信息一致，根据自己实际环境更改，这里只更改了必要的几个。broker.id三节点不能重复，zookeeper.connect写ip和主机名都可以
[root@kafka2 config]# vi server.properties
broker.id=1 #节点1
broker.id=2 #节点2
broker.id=3 #节点3
listeners=PLAINTEXT://:9092
log.dirs=/opt/kafka_2.11-1.0.0/kdata
zookeeper.connect=kafka1:2181,kafka2:2181,kafka3:2181
8.后台启动启动kafka进程
[root@kafka1 kafka_2.11-1.0.0]# bin/kafka-server-start.sh -daemon config/server.properties &
