这里使用三台机器搭建zookeeper集群环境。

ip	hostname
10.0.20.14	node1
10.0.20.15	node2
10.0.20.16	node3

下载

zookeeper下载页面

1	https://www.apache.org/dyn/closer.cgi/zookeeper/

下载对应的binary包

1	wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

解压包

1
2
3

tar zxf zookeeper-3.4.14.tar.gz
mv zookeeper-3.4.14 /opt/zookeeper
cd /opt/zookeeper/conf

配置Zookeeper

将zoo_sample.cfg文件复制为zoo.cfg文件

1	cp zoo_sample.cfg zoo.cfg

配置如下

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/logs
clientPort=2181
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

1	mkdir /opt/zookeeper/{data,logs}

配置myid

进入data目录，写入myid文件

1 2	cd data echo 1 > myid

每台机器中的myid不能重复，会导致zookeeper无法启动

分发配置

将zookeeper目录cp到其他机器

1 2	scp -r zookeeper/ 10.0.20.15:/opt/ scp -r zookeeper/ 10.0.20.16:/opt/

注意需要修改myid文件

配置环境变量

$ vim /etc/profile
export ZOOKEEPER_HOME=/opt/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin
$ source /etc/profile

启动Zookeeper

1	zkServer.sh start

查看Zookeeper状态

$ zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: follower
