前提：准备3台linux虚机  
下面是实操命令步骤

## 一、下载zk ##

\[app@zknode01 ~\]$ mkdir zookeeper  
\[app@zknode01 ~\]$ cd zookeeper  
\[app@zknode01 zookeeper\]$ mkdir zkdata  
\[app@zknode01 zookeeper\]$ mkdir zkdatalog  
\[app@zknode01 zookeeper\]$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz

## 二、解压zk ##

\[app@zknode01 zookeeper\]$ tar -xzvf zookeeper-3.4.13.tar.gz  
\[app@zknode01 zookeeper\]$ cd zookeeper-3.4.13/  
\[app@zknode01 zookeeper-3.4.13\]$ cd conf  
\[app@zknode01 conf\]$ cp zoo\_sample.cfg zoo.cfg

## 三、配置zoo.cfg ##

\[app@zknode01 conf\]$ vim zoo.cfg  
dataDir=/home/app/zookeeper/zkdata  
dataLogDir=/home/app/zookeeper/zkdatalog  
server.1=10.10.30.238:12888:13888  
server.2=10.10.30.239:12888:13888  
server.3=10.10.30.240:12888:13888  
*以上ip需配置实际地址*  
*node2和node3重复以上步骤*

## 四、配置myid ##

\[app@zknode01 ~\]$ echo “1” > /home/app/zookeeper/zkdata/myid  
\[app@zknode02 ~\]$ echo “2” > /home/app/zookeeper/zkdata/myid  
\[app@zknode03 ~\]$ echo “3” > /home/app/zookeeper/zkdata/myid

## 五、编辑zookeeper.out输出路径 ##

在zkEnv.sh  
修改ZOO\_LOG\_DIR="$ZOOKEEPER\_PREFIX/logs"

## 六、启动zk ##

**启动node01**  
\[app@zknode01 ~\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Starting zookeeper … STARTED  
\[app@zknode01 ~\]$

**启动node02**  
\[app@zknode02 conf\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Starting zookeeper … STARTED

**启动node03**  
\[app@zknode03 conf\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh start  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Starting zookeeper … STARTED

**查看node1状态**  
\[app@zknode01 ~\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Mode: follower  
\[app@zknode01 ~\]$

**查看node2状态**  
\[app@zknode02 conf\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Mode: leader  
\[app@zknode02 conf\]$

**查看node3状态**  
\[app@zknode03 conf\]$ /home/app/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status  
ZooKeeper JMX enabled by default  
Using config: /home/app/zookeeper/zookeeper-3.4.13/bin/…/conf/zoo.cfg  
Mode: follower  
\[app@zknode03 conf\]$

zk集群搭建完毕。
