JEESZ-Zookeeper集群安装

Posted 2021-01-26 qfjavabd

 

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

　　[[email protected] /]# 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

　　[[email protected] software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/

　　[[email protected] software]# scp -r /software/zookeeper-3.4.6.tar.gz [email protected]:/software/

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

　　[[email protected] 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)

　　[[email protected] /]# cd /zookeeper/

　　[[email protected] 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)

　　[[email protected] zookeeper]# mkdir zkdata

　　[[email protected] zookeeper]# mkdir zkdatalog

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

　　[[email protected] zookeeper]# cd /zookeeper/zookeeper-3.4.6/conf/

　　[[email protected] 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)

　　[[email protected] /]# cd /zookeeper/zkdata

　　[[email protected] /]# echo 1 myid

　　10. myid文件写入service2、service3

　　echo 2 myid

　　echo 3 myid

　　11.查看zk命令：

　　[[email protected] ~]# cd /zookeeper/zookeeper-3.4.6/bin/

　　[[email protected] 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：

　　[[email protected] 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

　　[[email protected] bin]# ./zkServer.sh start

　　14. jps查看zk进程

　　[[email protected] 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)

　　[[email protected] bin]# ./zkServer.sh status

　　JMX enabled by default

　　Using config: /zookeeper/zookeeper-3.4.6/bin/../conf/zoo.cfg

　　Mode: follower

　　[[email protected] 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
