Zookeeper+Kafka集群安装

Zookeeper+Kafka集群安装

详细记录下Zookeeper+Kafka集群安装过程。准备3台虚拟机, 系统是RHEL64服务版。

1) 每台机器配置如下:

$ cat /etc/hosts

...
# zookeeper hostnames:
192.168.8.182      zk1
192.168.8.183      zk2
192.168.8.184      zk3

2) 每台机器上安装jdk, zookeeper, kafka, 配置如下:

$ vi /etc/profile

...

# jdk, zookeeper, kafka
export KAFKA_HOME=/usr/local/lib/kafka/kafka_2.9.2-0.8.11
export ZK_HOME=/usr/local/lib/zookeeper/zookeeper-3.4.6
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$KAFKA_HOME/bin:$ZK_HOME/bin:$PATH

3) 每台机器上运行:

$ source /etc/profile

$ mkdir -p /var/lib/zookeeper

$ cd $ZK_HOME/conf

$ cp zoo_sample.cfg zoo.cfg

$ vi zoo.cfg

...

dataDir=/var/lib/zookeeper

# the port at which the clients will connect
clientPort=2181

# zookeeper cluster
server.1=zk1:2888:3888
server.2=zk2:2888:3888
server.3=zk3:2888:3888

4) 每台机器上生成myid:

zk1:

$ echo "1" > /var/lib/zookeeper/myid

zk2:

$ echo "2" > /var/lib/zookeeper/myid

zk3:

$ echo "3" > /var/lib/zookeeper/myid

5) 每台机器上运行setup关闭防火墙

Firewall:

[  ] enabled

6) 每台机器上启动zookeeper:

$ zkServer.sh start

查看状态:

$ zkServer.sh status
