jeesz分布式架构-zookeeper集群安装
利用AWS快速构建适用于生产的无服务器应用程序,免费试用12个月>>>   

1. 在根目录创建zookeeper文件夹(service1、service2、service3都创建)

[root@localhost /]# mkdir zookeeper

通过Xshell上传文件到service1服务器:上传zookeeper-3.4.6.tar.gz到/software文件夹


2.远程copy将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 root@192.168.2.212:/software/

[root@localhost software]# scp -r /software/zookeeper-3.4.6.tar.gz root@192.168.2.213:/software/

 

3.copy /software/zookeeper-3.4.6.tar.gz到/zookeeper/目录(service1、service2、service3都执行)

[root@localhost software]# cp /software/zookeeper-3.4.6.tar.gz /zookeeper/

 

4.安装解压zookeeper-3.4.6.tar.gz(service1、service2、service3都执行)

[root@localhost /]# cd /zookeeper/

[root@localhost zookeeper]# tar -zxvf zookeeper-3.4.6.tar.gz

 

5.在/zookeeper创建两个目录:zkdata、zkdatalog(service1、service2、service3都创建)

[root@localhost zookeeper]# mkdir zkdata

[root@localhost zookeeper]# mkdir zkdatalog

 

6.进入/zookeeper/zookeeper-3.4.6/conf/目录

[root@localhost zookeeper]# cd /zookeeper/zookeeper-3.4.6/conf/

[root@localhost conf]# ls

configuration.xsl  log4j.properties  zoo.cfg  zoo_sample.cfg

 

7. 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

 

8. 同步修改service2、service3的zoo.cfg配置

 

9. myid文件写入(进入/zookeeper/zkdata目录下)

[root@localhost /]# cd /zookeeper/zkdata

[root@localhost /]# echo 1 > myid

 

10. myid文件写入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.执行zkServer.sh查看详细命令:

[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}

 

13. 在service1、service2、service3分别启动zk服务

[root@localhost bin]# ./zkServer.sh start

 

14. jps查看zk进程

[root@localhost bin]# jps

31483 QuorumPeerMain

31664 Jps

 

15. 分别在service1、service2、service3查看zk状态(可以看到leader和follower节点)

[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

 

16. 看到leader和follower节点已经安装成功
