zookeeper安装二:集群安装

    xiaoxiao2021-04-16  220

    实验环境:

    1. centos7.6最小化安装 2. jdk1.8 3. zookeeper-3.4.14

    安装步骤

    大致类似上一篇文章:zookeeper安装一:单机安装 区别:

    1. 在上一个单机安装装的技术上增加两台机器

    分别是192.168.255.130,192.168.255.131,192.168.255.132

    2. 它们的配置文件zoo.cfg在最末尾都加上

    server.1=192.168.255.130:2888:3888 server.2=192.168.255.131:2888:3888 server.3=192.168.255.132:2888:3888

    3. 在各自机器的dataDir目录下新建文件myid

    192.168.22.130的myid文件内容为1 192.168.22.131的myid文件内容为2 192.168.22.132的myid文件内容为3

    4. 依次启动130,131,132

    [root@localhost bin]# ./zkServer.sh start ZooKeeper JMX enabled by default Using config: /soft/zookeeper-3.4.14/bin/…/conf/zoo.cfg Starting zookeeper … STARTED 每个机器启动后的输出文件都是这样的

    5. 在任意台机器上去连这个集群

    [root@localhost bin]# ./zkCli.sh -server 192.168.255.130:2181,192.168.255.131:2181,192.168.255.132:2181 可以看到以下输出: … Welcome to ZooKeeper!

    关闭的时候可以依次关闭单个机器,这个没有试验。
