When dealing with database, sometime we want to make backup database. I usually use mysqldump to store all database in sql file. The problem is when running, mysqldump ask us to provide password. If you must enter password everytime you run the command, you cannot make it run automatically with crontab script
So, how to solve it???
Well, mysqldump allow us can run automaticall with an configuration file was located at ~/.my.cnf. Format of this file is
[mysqldump]
host=<your_host_name>
username=<your_user_name>
password=<your_password>And the file need to set in mod 600
