三台虚拟机集群失败

Question

zoo.cfg配置

三台都配置了myid，互相能ping通，三台zookeeper服务都启动后，启动客户端报错如下：

对了，你这个是启动一台报的错吗？？如果是，那就启动三台，集群状态下，启动一台，再用zkCli.sh 的话zk会报错，你必须三台全部启动才能连接客户端

• 提问者 callme激流 #1

  三个zoo.cfg，集群配置都配置了，也三台都启动了。可奇怪了就是不行

• 风间影月 回复 提问者 callme激流 #2

  三台启动就可以用zkCli连接了，不行的话建议你再跟着视频走一下吧~~

集群配置 server.1 2 3分别在三台机子配置了吗？

Answer 3

另外三台虚拟机要注意，使用桥接，不要使用宿主

• 提问者 callme激流 #1

  老师，我记得创建虚拟机时候用的是桥接，配置静态ip时候
  修改了/etc/sysconfig/network-scripts下的文件
  BOOTPROTO="static"
  BROADCAST=192.168.1.255
  IPADDR=192.168.1.111
  NETMASK=255.255.255.0
  GATEWAY=192.168.1.1
  DNS1=8.8.8.8

• 风间影月 回复 提问者 callme激流 #2

  每台机子的IP都是独立的，都是同网段的

• 提问者 callme激流 回复 风间影月 #3

  我配置的111,112,113
