==Recovering a system where pre-backup could not be run==
{{Warning box| Only use this procedure where pre-backup cannot be run eg in the event of a corrupt filesystem and/or unbootbale server}}
This addresses the situation where the pre-backup was unable to be run eg a sudden power outage that has caused a corrupt filesystem and unbootable server, it concerns the recovery of your mysql db's . It should not be the general case for this procedure, only if you are in a recovery situation where pre-backup is not an option.
The mysql db's are kept in: /var/lib/mysql
Stop the mysql service:
service mysqld stop
Change directories to the old mysql:
cd /mnt/old/var/lib/
Copy the mysql db's to the new install:
cp -R ./mysql /var/lib/
Change directories to the new mysql:
cd /var/lib/
Change the ownership on the new install mysql directory:
chown -R mysql:mysql ./mysql
Restart the mysqld service:
service mysqld start
