Solved: Bamboo doesn't support MySQL version 5.5.5-10.1.26-MariaDB-0+deb9u1

Question

Got this error while trying to install latest Bamboo:

2018-03-10 11:37:04,456 FATAL [performSetupDatabaseConnectionBackgroundThread] [DefaultBootstrapManager] Validation tests failed: [Task 51111 failed with exception: Bamboo doesn't support MySQL version 5.5.5-10.1.26-MariaDB-0+deb9u1.

Is there any workaround for this issue? I have jira, crowd, bitbucket and confluence on the same server - all works fine but bamboo...

There is indeed a workaround but keep in mind MariaDB is unsupported. This means that while the MariaDB fork aims to maintain high compatibility with MySQL APIs, we don't test against it and compatibility isn't guaranteed. If it turns out MariaDB doesn't work in some scenarios, a bug fix isn't guaranteed.

Here's a list of supported platforms for the latest version of Bamboo:

* Supported Platforms

MariaDB 5.5 is also based on MySQL 5.5 which we dropped support for in Bamboo 5.12+. It'll probably be fine, but it's a risk -- take precautionary backups just to be safe.

The validation check for MySQL can be disabled with the below JVM argument:

-Dbamboo.upgrade.fail.if.mysql.unsupported=false

I've included the documentation that explains configuring system properties / JVM arguments in Bamboo below:

Hope this helps. :)
