Assuming you are a superuser, create a new database:
[code]mysqladmin -p create db_name[/code]
[code]mysql -p db_name < db_name.sql[/code]
Dump the db:
[code]mysqldump -p –opt db_name > db_name.sql[/code]
Here’s a script called db_backup (make the file executable with chmod a+x filename):
# dumb the dbs
mysqldump -u$db_user -p$db_pass –opt asterisk > $path/asterisk.sql
mysqldump -u$db_user -p$db_pass –opt gallery2 > $path/gallery2.sql
mysqldump -u$db_user -p$db_pass –opt wordpress > $path/wordpress.sql
# create an archive, cleanup
tar -P -zcf $path/$filename $path/*.sql
rm -f $path/*.sql
Edit the crontab with crontab -e and add the following line (which runs every day at 11 pm and logs to the file specified):
0 23 * * * /backup/db_backup.sh >> /var/log/db_backup.log
Alternately you can backup all databases with one command:
mysqldump –all-databases -p > mysqlbackup.sql
Or backup the database files directly from /var/lib/mysql/. You don’t have to be a guru to administer your databases (though some knowledge of relational databases & SQL definitely helps). PHPMyAdmin is a handy tool that you should setup if you haven’t already.
