, just in case the main library fails, from the library after taking over the account information, it is difficult to recover, and if the main library account more, there is a great risk. This is possible if the data is backed up from the point of view and the number of accounts is not many (or if the MySQL database on the main library is backed up).4) Add read-only parameters from the library before startingThis approach is close to perfect, but not without risk, first of all, read-only can not
