官網：

1、建立目錄

cd /usr/local


mkdir zookeeper-cluster


cd zookeeper-cluster


mkdir server1


cd server1
將解壓的zookeeper資料夾複製到當前目錄，並在當前目錄下建立：

mkdir data


mkdir datalog


cd data


touch myid


echo 1 > myid
2、配置

cd /usr/local/zookeeper-cluster/server1/zookeeper/conf


touch zoo.cfg
內容如下

ticktime=2000 


initlimit=5


synclimit=2


datadir=/usr/local/zookeeper-cluster/server1/data


datalogdir=/usr/local/zookeeper-cluster/server1/datalog


clientport=2181


server.1=127.0


.0.1:2888:3888


server.2=127.0


.0.1:2889:3889


server.3=127.0


.0.1:2890:3890
3、複製server1為server2和server3，並修改其中的zoo.cfg和myid

3個zoo.cfg內容：

# server1


ticktime=2000


initlimit=5


synclimit=2


datadir=/usr/local/zookeeper-cluster/server1/zookeeper/data


datalogdir=/usr/local/zookeeper-cluster/server1/zookeeper/datalog


clientport=2181


server.1=127.0


.0.1:2888:3888


server.2=127.0


.0.1:2889:3889


server.3=127.0


.0.1:2890:3890


# server2


ticktime=2000


initlimit=5


synclimit=2


datadir=/usr/local/zookeeper-cluster/server2/zookeeper/data


datalogdir=/usr/local/zookeeper-cluster/server2/zookeeper/datalog


clientport=2182


server.1=127.0


.0.1:2888:3888


server.2=127.0


.0.1:2889:3889


server.3=127.0


.0.1:2890:3890


# server3


ticktime=2000


initlimit=5


synclimit=2


datadir=/usr/local/zookeeper-cluster/server3/zookeeper/data


datalogdir=/usr/local/zookeeper-cluster/server3/zookeeper/datalog


clientport=2183


server.1=127.0


.0.1:2888:3888


server.2=127.0


.0.1:2889:3889


server.3=127.0


.0.1:2890:3890
myid的內容分別為 1、2、3

分別進入三個伺服器資料夾的解壓目錄的/bin目錄下，啟動服務

cd /usr/local/zookeeper-cluster/server1/zookeeper/bin


./zkserver.sh start


cd /usr/local/zookeeper-cluster/server2/zookeeper/bin


./zkserver.sh start


cd /usr/local/zookeeper-cluster/server3/zookeeper/bin


./zkserver.sh start
4、接入客戶端

隨意進去一台server的/bin目錄下，並連線其他任一台伺服器(此處進去server3連線server1)
