Zookeeper集群安装

标签：conf   you   enabled   snapshot   leader   which   文件   cleanup   写入   

[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/

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/

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

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

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

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
