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。。。
