JEESZ-Zookeeper集群安装

阳光

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
