Question

mysqldump managed database through cron

From https://docs.digitalocean.com/products/databases/mysql/how-to/import-databases/#export-with-mysqldump

I got below: mysqldump -u doadmin -p -h mysql-test-do-user-4915853-0.db.ondigitalocean.com -P 25060 --single-transaction --set-gtid-purged=OFF your_database_name \

/path/to/database_file.sql

Trying to use this in a cronjob without success (adding password to above). Is it not doable to mnysqldump a digitalocean managed database through cronjob?

I noticed “The application prompts you for your MySQL doadmin user password.” from above URL. Does that mean you cant authenticate through cron command?

Thanks

Hello,

What I could suggest is following the steps from this tutorial here on how to how to create an export script to backup your database:

https://devdojo.com/bobbyiliev/how-to-exportbackup-a-mysqlmariadb-database-with-mysqldump

It suggests the following:

In order to do that you need to make sure that you have the following content in your .my.cnf file. The file should be stored at:

/home/your_user/.my.cnf

You should make sure that it has secure permissions:

chmod 600 /home/your_user/.my.cnf

And you should add the following content:

[client]
user=your_mysql_user
password=your_mysql_password

Once you have your .my.cnf file configured, you set up a cronjob to trigger the mysqldump export of your database.

Let me know how it goes!

Best,

Bobby
