Where can i find the MySQL database file in Linux Filesystem
I'm an MS Access user for several years, then I switch to MySQL. I know how to backup and restore the database in MySQL in a Linux environment, but it only works when the MySQL daemon is running. One time, our server (SuSE Linux 9.3 Prof) crashes, and I can't run all the services, and one of them is MySQL, so I have trouble making backup of our School's Forum.
I tried to search the entire filesystem to find the exact file where my tables are located but I'm not sure what i'm doing. I noticed, in Windows, MySQL tables are saved as .frm files, ex. msgboard.frm.
So here are my questions:
1. What directory the MySQL database is stored (in Linux of course)?
2. If ever i find those files, is there any commands to restore those database file to another system? In windows, I copied and paste it, but it doesn't work of course. is there a way on restoring those files? (not mysqldump files)
Another: I have some trouble in restoring my backups. When I make backup, i used this command.
mysqldump db_name -u root -p > our_db_backup.sql
And when i need to restore the database, i need to append the name of the database to all tables of the entire SQL script like this:
create table 'table_name' ...
create table 'db_name'.'table_name' ....
so that this restoration works:
mysql -u root -p < our_db_backup.sql
Is there any way so that I don't have to edit the SQL script evertime i need to restore the database? I think there's a switch lacking.
I really appreciate your help. Thank you.
to restore the database, create it first then
mysql yourDATABASENAME < yourSQL.sql -u root -p
Your data reside in a directory that you may find reading
look for data directory entry. Could be somewhere in /var/lib/mysql but depending on how you installed mysql it can be anywhere.
Why dont you start the server and make a dump?
Making automatic backup
Ok, i have now learned how to restore from my dump file. thank you very much dude.
I want to make an automatic backup of my database, that is i want to make backup weekly.
I know how to make script, but i want to know what is the name of the program that run applications scheduled, even if the user is not logged in. is it "cron" ???
tnx in advance.
maybe there are directories for cron jobs on your box already. If so you can place your script there and have it executed automatically.
