Codis Dashboard：[error]: dashboard already exists: {“addr”:
有时候，Codis的Dashboard可能起不来，如下：

[root@codis-server1 ~]# cd /data/go_me/src/github.com/CodisLabs/codis/ [root@codis-server1 codis]# bin/codis-config dashboard 2016/08/20 13:45:28 dashboard.go:160: [INFO] dashboard listening on addr: :18087 2016/08/20 13:45:30 dashboard.go:234: [PANIC] create zk node failed [error]: dashboard already exists: {"addr": "10.158.1.94:18087", "pid": 23586} [stack]: 3 /data/go_me/src/github.com/CodisLabs/codis/cmd/cconfig/dashboard.go:234 main.runDashboard 2 /data/go_me/src/github.com/CodisLabs/codis/cmd/cconfig/dashboard.go:54 main.cmdDashboard 1 /data/go_me/src/github.com/CodisLabs/codis/cmd/cconfig/main.go:85 main.runCommand 0 /data/go_me/src/github.com/CodisLabs/codis/cmd/cconfig/main.go:152 main.main ... ...

解决方法：
在之前，Codis Dashboard启动成功的时候，是这样的：
