## 先在hadoop001上部署
[hadoop@hadoop001 ~]$ tar -xzvf /home/hadoop/software/zookeeper-3.4.5-cdh5.16.2.tar.gz -C /home/hadoop/app/
[hadoop@hadoop001 ~]$ cd ~/app/
## 創(chuàng)建軟連接
[hadoop@hadoop001 app]$ ln -s zookeeper-3.4.5-cdh5.16.2/ zookeeper
[hadoop@hadoop001 app]$ cd zookeeper/conf/
## 配置conf文件
[hadoop@hadoop001 conf]$ cp zoo_sample.cfg zoo.cfg
[hadoop@hadoop001 conf]$ vim zoo.cfg
# 修改數(shù)據(jù)目錄
dataDir=/home/hadoop/data/zookeeper
# 添加zookeeper的通信端口和選舉端口
server.1=hadoop001:2888:3888
server.2=hadoop002:2888:3888
server.3=hadoop003:2888:3888
# 添加并配置myid文件
[hadoop@hadoop001 conf]$ mkdir? /home/hadoop/data/zookeeper
[hadoop@hadoop001 conf]$ echo 1 > /home/hadoop/data/zookeeper/myid
[hadoop@hadoop001 conf]$ cat /home/hadoop/data/zookeeper/myid
1
## 在hadoop002和hadoop003上配置
[hadoop@hadoop002 ~]$ mkdir? /home/hadoop/data/zookeeper
[hadoop@hadoop002 ~]$ echo 2 > /home/hadoop/data/zookeeper/myid
[hadoop@hadoop002 ~]$ cat /home/hadoop/data/zookeeper/myid
2
[hadoop@hadoop003 ~]$ mkdir? /home/hadoop/data/zookeeper
[hadoop@hadoop003 ~]$ echo 3 > /home/hadoop/data/zookeeper/myid
[hadoop@hadoop003 ~]$ cat /home/hadoop/data/zookeeper/myid
3
## 拷貝hadoop001上的 ~/app/zookeeper-3.4.5-cdh5.16.2/ 到hadoop002和hadoop003上，同時(shí)修改所屬用戶和組，創(chuàng)建軟連接
[hadoop@hadoop001 conf]$ scp -r ~/app/zookeeper-3.4.5-cdh5.16.2/ hadoop002:/home/hadoop/app/
[hadoop@hadoop001 conf]$ scp -r ~/app/zookeeper-3.4.5-cdh5.16.2/ hadoop003:/home/hadoop/app/
## 創(chuàng)建軟連接
[hadoop@hadoop002 ~]$ cd ~/app/
[hadoop@hadoop002 app]$ ln -s zookeeper-3.4.5-cdh5.16.2/ zookeeper
[hadoop@hadoop003 ~]$ cd ~/app/
[hadoop@hadoop003 app]$ ln -s zookeeper-3.4.5-cdh5.16.2/ zookeeper
## 啟動(dòng)
[hadoop@hadoop001 app]$ cd ~/app/zookeeper
[hadoop@hadoop002 app]$ cd ~/app/zookeeper
[hadoop@hadoop003 app]$ cd ~/app/zookeeper
[hadoop@hadoop001 zookeeper]$ bin/zkServer.sh start

## 配置環(huán)境變量
[hadoop@hadoop001 ~]$ echo -e '# ZOOKEEPER ENV\nexport ZOOKEEPER_HOME=/home/hadoop/app/zookeeper\nexport PATH=$ZOOKEEPER_HOME/bin:$PATH' >> ~/.bashrc
