Does Shutdown Erase Data


I have a wordpress site running on a server, and I unfortunately need to reset the root password because I forgot it. To do that I need to shutdown.

Does a shutdown erase data, such as the files and database for my wordpress site? I am inclined to believe data is just stored on the machine’s hard drive and will persist. However, I have made the mistake of shutting down a server in AWS with some data on its physical disk, and I know that in that case that data is gone forever. I just want to make sure.

Thanks EDIT: I am aware of the risk of losing/corrupting some data that is being processed/accessed in some way at the time of shutdown. I don’t believe this would really apply to a closed development Wordpress site, so my question is about whether most static data that is just sitting there will be fine.

Accepted Answer

If you’re worried about possibly losing data, I’d shut down the MySQL service then shut down the entire server.

Any data written to disk should be preserved so long as the server is shutdown gracefully through the command prompt.
