Comment 5 for bug 1708376

hello, Yiu-Chung Lee I tried a new solution. I have observed that the write requirepass before the restart. So we need to ensure that, from this instance to start to change the configuration to close the database before the use of a client. (For example, when we write this parameter for the first time, we should ensure that the client is shutting down the database when the restart, the client is without requirepass, otherwise it will be error.) But we also have to do before the restart, Let client require require so that client can ping. I put the generic restart method to get the redis guestagent to rewrite, beaten for this purpose. Please see my changes.
