I have the suspiction that my MySQL installation and all databases are somehow borked. For a fresh start, I would like to create dumps from all the databases, uninstall MySQL, delete the data in /var/lib/mysql, reinstall MySQL, and then import all the dumps.

I know I could figure out the individual commands for each step.

But is there a more convenient, automated way to do this all at once, where I can leave the computer alone for a while, come back and it is finished?

$ mysql --version
mysql  Ver 14.14 Distrib 5.6.19, for debian-linux-gnu (x86_64) using  EditLine wrapper

    Dump the data for security, but simply reinstall on top of the existing install. Why do you think it is borked?

  • "Why do you think it is borked?" - Some slow queries. I could be wrong. But I think if we start to discuss this here it will hopelessly derail from the actual question. So let's just not :)

  • "Dump the data for security, but simply reinstall on top of the existing install." - well this won't really "rebuild" the storage structure, so it would be kind of pointless.

  • Also, from last time I read up on this, I remember that the files in /var/lib/mysql are not really self-sufficient and replaceable, but depend on some kind of global identifiers. This seems like a fragile system to me. I already did this with the data, and who knows what went wrong.
