- 在根目錄創建zookeeper文件夾（service1、service2、service3都創建）
[root@localhost /]# mkdir zookeeper
通過Xshell上傳文件到service1服務器：上傳zookeeper-3.4.6.tar.gz到/software文件夾
2.遠程copy將service1下的/software/zookeeper-3.4.6.tar.gz到service2、service3
[root@localhost software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/
[root@localhost software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/
3.copy /software/zookeeper-3.4.6.tar.gz到/zookeeper/目錄（service1、service2、service3都執行）
[root@localhost software]# cp /software/zookeeper-3.4.6.tar.gz /zookeeper/
4.安裝解壓zookeeper-3.4.6.tar.gz（service1、service2、service3都執行）
[root@localhost /]# cd /zookeeper/
[root@localhost zookeeper]# tar -zxvf zookeeper-3.4.6.tar.gz
5.在/zookeeper創建兩個目錄：zkdata、zkdatalog（service1、service2、service3都創建）
[root@localhost zookeeper]# mkdir zkdata
[root@localhost zookeeper]# mkdir zkdatalog
6.進入/zookeeper/zookeeper-3.4.6/conf/目錄
[root@localhost zookeeper]# cd /zookeeper/zookeeper-3.4.6/conf/
[root@localhost conf]# ls
configuration.xsl log4j.properties zoo.cfg zoo_sample.cfg
- 修改zoo.cfg文件
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
syncLimit=5
the directory where the snapshot is stored.
do not use /tmp for storage, /tmp here is just
example sakes.
dataDir=/zookeeper/zkdata
dataLogDir=/zookeeper/zkdatalog
the port at which the clients will connect
clientPort=2181
the maximum number of client connections.
increase this if you need to handle more clients
#maxClientCnxns=60
Be sure to read the maintenance section of the
administrator guide before turning on autopurge.
The number of snapshots to retain in dataDir
autopurge.snapRetainCount=3
Purge task interval in hours
Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.2.211:12888:13888
server.2=192.168.2.212:12888:13888
server.3=192.168.2.213:12888:13888
-
同步修改service2、service3的zoo.cfg配置
- myid文件寫入（進入/zookeeper/zkdata目錄下）
[root@localhost /]# cd /zookeeper/zkdata
[root@localhost /]# echo 1 > myid
- myid文件寫入service2、service3
echo 2 > myid
echo 3 > myid
11.查看zk命令：
[root@localhost ~]# cd /zookeeper/zookeeper-3.4.6/bin/
[root@localhost bin]# ls
README.txt zkCleanup.sh zkCli.cmd zkCli.sh zkEnv.cmd zkEnv.sh zkServer.cmd zkServer.sh zookeeper.out
12.執行zkServer.sh查看詳細命令：
[root@localhost bin]# ./zkServer.sh
JMX enabled by default
Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Usage: ./zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd}
- 在service1、service2、service3分別啓動zk服務
[root@localhost bin]# ./zkServer.sh start
- jps查看zk進程
[root@localhost bin]# jps
31483 QuorumPeerMain
31664 Jps
- 分別在service1、service2、service3查看zk狀態（可以看到leader和follower節點）
[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: follower
[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: leader
- 看到leader和follower節點已經安裝成功
