* First, make sure MySQL is *not* running. :-) * There are 4 important data files in /var/lib/mysql that MySQL uses to keep things running properly. These are 'ib_arch_log_0000000000', 'ib_logfile0', 'ib_logfile1' and 'ibdata1'. If you do not see these files present, you will need to reinstall MySQL before trying to restore the DBs. * Copy each <db_name> directory into /var/lib/mysql from your backup(s) * Run 'myisamchk /var/lib/mysql/<db_name>/*.MYI' for each db * Start MySQL and watch your logfiles for any errors or other problems If everything went well, your db should be restored and everything working again. (Note: the 'mysql' db is where MySQL stores usernames and logins. If you have a program/script/webpage that is not able to login to mysql, you probably need to restore your 'mysql' db as well.)
