保存

把zoo.cfg拷贝到其他主机

scp zoo.cfg root@192.168.111.112:/opt/zookeeper/conf

进入配置文件dataDir设置的文件夹里

创建 myid 的文件 并把server.id填写进去 例如 server.1=192.168.111.111:2888:3888 id是1

vim myid

内容为1

启动zookeeper

进入/opt/zookeeper/bin目录 执行

./zkserver.sh start

(我apt安装的启动方式是/usr/share/zookeeper/bin/zkServer.sh start)

验证是否启动

telnet 192.168.111.111 2181 (mac安装:brew install telnet)

echo stat | nc 192.168.111.111 2181

输入stat显示信息

root@xiaokang4:/usr/share/zookeeper/bin# telnet 192.168.111.113 2181

Trying 192.168.111.113...
