codsi错误 启动dashboard失败:store: acquire lock of codis-tes

背景：春季前由于要停电，所以直接使用关闭命名shutdown,没有手动关闭codis，导致启动codis dashboard失败。

需要删除zookeeper的节点

具体代码示例：

1、确认codis-dashboard进程已经退出（很重要）

codis-admin?--dashboard=192.168.3.190:18080?--shutdown

2、然后运行codis-admin删除LOCK：

codis-admin?--remove-lock?--product=codis_demo?--zookeeper=127.0.0.1:2181

####?结果
2019/07/25?10:51:11?zkclient.go:23:?[INFO]?zookeeper?-?zkclient?setup?new?connection?to?127.0.0.1:2181
2019/07/25?10:51:11?zkclient.go:23:?[INFO]?zookeeper?-?Connected?to?127.0.0.1:2181

codis_demo是codis的项目名字

127.0.0.1:2181对应的zookeeper的ip地址

最后：

重启codis-dashboard
