@zookeeper

1 下载 ZK

wget  http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.7/zookeeper-3.4.7.tar.gz

2 解压

tar -zxvf zookeeper-3.4.7.tar.gz

3 修改配置文件 

cp zoo_sample.cfg zoo.cfg  

mv zookeeper-3.4.6/conf/zoo_sample.cfg zookeeper-3.4.6/conf/zoo.cfg

vi zoo.cfg

tickTime=2000
dataDir=/usr/local/opt/zookeeper/data
clientPort=2181
initLimit=10
syncLimit=5
server.1=s1:2888:3888
server.2=s2:2888:3888
server.3=s3:2888:3888

4 创建 myid

在 zoo.cfg 中的 dataDir  文件夹中创建 myid

mkdir -p /home/hadoop/zookeeper/data

三台机分别

echo "1"> /home/hadoop/zookeeper/data/myid

echo "2"> /home/hadoop/zookeeper/data/myid

echo "3"> /home/hadoop/zookeeper/data/myid

5 三机启动

./zookeeper-3.4.6/bin/zkServer.sh start

./bin/zkServer.sh start

6 验证

./zookeeper-3.4.6/

./bin/zkServer.sh status

或

进入 ./zookeeper-3.4.6/bin/zkCli.sh -server s1:2181
