For some reason my /var/run/ dir on debian6 had it's chown and chmod changed. Problem is from what? Outcome is that mysql fails. I'm guessing the easiest way to fix is to reinstall MySQL. (Previously this LAMP was running fine.)
However, I have established databases and tables and don't want to lose them. Since mysql is not running I can't backup (correct?).
I just want to confirm that:
1). if I reinstall, I won't loose my databases.
apt-get install mysql-server mysql-client is the correct command to use.
