1. centos7.6最小化安装 2. jdk1.8 3. zookeeper-3.4.14
大致类似上一篇文章:zookeeper安装一:单机安装 区别:
分别是192.168.255.130,192.168.255.131,192.168.255.132
server.1=192.168.255.130:2888:3888 server.2=192.168.255.131:2888:3888 server.3=192.168.255.132:2888:3888
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
[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

关闭的时候可以依次关闭单个机器,这个没有试验。
