What should I do if the restore genie restored mysql? I recently attended practical training courses in the school data center, so I had to frequently communicate with the data center. The recovery wizard installed on the computer room restores my mysql every day. It's a headache. Fortunately, the restore wizard only restores the Registry file and does not restore the hard disk. Therefore, we still have hope. 1. If the backup registry does not back up the registry, uninstall it and reinstall it again. At present, I have no solution... The backup process is as follows: the principle is that mysql has traces of user and local_machine in the registry, so we need to back up the data. 1. run regedit to enter the Registry 2. export the local machine-> software-> mysql registry 3. to export the user-> software-> mysql registry, save the settings. restore the registry and double-click the backup registry to import it. III. install mysql Services 1. enter the mysql/bin folder (for example, this folder is in E: \ Program Files \ MySQL Server 5.5 \ bin-> e: (enter the E disk)-> cd E: \ Program Files \ MySQL Server 5.5 \ bin (enter this directory) 2. -mysqld-install (install the service) 3. -net start mysql, # set basedir to your installation path set the mysql installation directory basedir = E: \ Program Files \ MySQL Server 5.5 # set datadir to the location of you R data directory set database directory datadir = E: \ Program Files \ MySQL Server 5.5 \ data [WinMySQLAdmin] Server = G: /mysql/bin/mysqld-nt.exe 4. -net start mysql service is finally started.
