1.下載上傳文件到centos中

2.解壓文件夾

3.cd conf 文件下，cp zoo_sample.cfg zoo.cfg

4.vim zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/zookeeper
# the port at which the clients will connect

# the maximum number of client connections.
# increase this if you need to handle more clients

server.1=192.168.121.131:2888:3888
server.2=192.168.121.129:2888:3888

設置文件如上所示：

ip地址也可以用主機名代替

5.創建myid文件，在/opt/zookeeper 文件夾下 創建myid 運行命令 touch myid , 然後寫入數字 echo 1 >myid

6.在192.168.121.129 中也如192.168.121.131相關的操作

7.關掉防火墻，或者打開相應的端口

8.cd 到 bin 目錄下

9.啟動server.1 然後啟動 server.2 ，./zkServer.sh start

10.過一段時間運行./zkServer.sh status 查看狀態如果顯示下面的信息則表示成功

[[email protected] bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/fuyuanming/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: leader

或者：

[[email protected] bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/fuyuanming/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: follower

表示成功
