Linux系统Codis集群搭建常见异常

• create zk node failed

• [root@localhost codis]# bin/codis-config dashboard
  2016/04/27 18:26:08 dashboard.go:160: [INFO] dashboard listening on addr: :18087
  2016/04/27 18:26:08 dashboard.go:234: [PANIC] create zk node failed
  [error]: dashboard already exists: {"addr": "192.168.75.141:18087", "pid": 59257}
  [stack]: 
      3   /home/listen/go/go/src/github.com/CodisLabs/codis/cmd/cconfig/dashboard.go:234
              main.runDashboard
      2   /home/listen/go/go/src/github.com/CodisLabs/codis/cmd/cconfig/dashboard.go:54
              main.cmdDashboard
      1   /home/listen/go/go/src/github.com/CodisLabs/codis/cmd/cconfig/main.go:85
              main.runCommand
      0   /home/listen/go/go/src/github.com/CodisLabs/codis/cmd/cconfig/main.go:152
              main.main
          ... ...
  

  解决方案：初步kill掉dashboard，不能加-9参数，再启动，如果不成功则登陆zookeeper，删除dashboard，重启即可。最彻底的办法还是删除dashboard。

  连接上其中的一台zookeeper，找到dashboard，删除

  解决方案：codis集群第一次启动时需要执行，后续再启动不需要执行

未完待续。。。
