CentOS下安装zookeeper

Posted 2020-06-09

Linux下安装Zookeeper集群步骤

(1) 下载zookeeper安装包

　　地址：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

(2) 解压安装包并放置在对应的路径下

　　解压对应文件到对应的路径下，本文将zookeeper解压到/soft/zk路径下，并在zk路径下建立 dataDir与dataLogDir路径

　　cd /soft/zk

　　tar -xvf zookeeper-xxx.tar.gz

　　mkdir dataDir

　　mkdir dataLogDir

 

(3) 配置zookeeper的配置文件

　　对zookeeper进行配置

　　cd /soft/zk/zookeeper-xxx/conf

　　cp zoo-sample.cfg zoo.cfg

　　vim zoo.cfg

　　

# 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=/soft/zk/dataDir
dataLogDir=/soft/zk/dataLogDir
# the port at which the clients will connect
clientPort=2181
server.1=192.168.1.111:2888:3888
server.2=192.168.1.112:2888:3888
server.3=192.168.1.113:2888:3888

这里对zookeeper服务器进行配置，这里需要将myid与对应的服务器编号对应

 

(4) 设置zookeeper对应的myid文件

　　cd /soft/zk/dataDir

　　vim myid

　　将服务器编号放入

 

(5) 启动zookeeper服务

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh start

　　启动服务，注意查看zookeeper.out这个日志输出，可以看到问题点

 

(6) 验证zookeeper是否正常启动

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh status

　　sh zkCli.sh -server 192.168.1.111:2181

 

(7) 查询zookeeper服务器对应的主从关系状态

　　cd /soft/zk/zookeeper-xxx/bin

　　sh zkServer.sh status
