Hi Fili. You could try it. The username should be the username and password should be those assigned for use of that database (rather than a customer login).

Otherwise, what I outlined above should work for you.

It is also possible to specify a location of your .my.cnf file on the command line:

/usr/bin/mysqldump –defaults-file=/path/to/.my.cnf -u root mydatabase

Put this in the .my.cnf file

[client]
password=mypassword

A good article and reference, although some comments complicates it, just following the tips will aid to create a good cron.
Many thanks!

Koesmanto, I found some references at Google. Specifically, this discussion at the A Small Orange forums might help. Otherwise, you may have to tweak the code a bit, as servers differ from one to the next.

I am having some problem with cron and .my.cnf. maybe you, diane, or james or Mike aka Jy can help.

2 scenarios:

1. i set up ~/.my.cnf file with the user name and password and host. then i set up my cron job. i am 100% sure that the username and password are correct because i manually run the script and it did what it needs to do. i went to the backup folder today and the backup files were created but they were blank. so i proceded with the #2

2. i disabled ~/.my.cnf file and actually have -u -p in my shell mysqldump script and the set the cron job up to run again in 5 minutes. 5 minutes later, i found the backup files with content in the backup folder.

my conclusion: the ~/.my.cnf file wasnt being read. what did i do wrong? any suggestions?

Well, I've set mine up a little differently by moving the individual programs to .sh files, but it would be cronjobs (or wahtever your crontab file is called). In fact, you could put the whole thing in cronjobs:

50 23 * * * /server/path/to/file.sh

where do you specify 50 23 * * * /server/path/to/file.sh, diane?

i have a dedicated server, but thanks for the advice, i am looking into my.cnf file now.

It looks like you're using James' version, as I'm not sure what datetime does. I specify time of file running like this:

50 23 * * * /server/path/to/file.sh

... which means 11:50 PM (23rd hour, 50th minute). The mailto command should be after the bin/bash (mine is different). What you *could* do is to set it to run in five minutes; upload it and reset via the ~cronjobs command, and see if it works. If it doesn't then you tweak. By the way, however inelegantly put by Mike aka Jy (I don't do Digg) above, his suggestion to move the root password elsewhere is good, especially if you're using a shared web host.
