Bitbucket Server fails to connect to MySQL database either when installing it or migrating databases. The following appears in the atlassian-bitbucket.log:

The schema could not be created.

原因

The issue here is that the MySQL documentation indicates that unquoted identifiers can only contain letters, numbers, $ and _. -'s (hyphens) are not supported in unquoted literals. The schema management tool Bitbucket Server uses (Liquibase) generally does a good job of escaping names for us, but sometimes it misses it. Bitbucket Server internally uses underscores in all of our names for this exact reason.

ソリューション

A name for the database like nbbitbucket or nb_bitbucket should work.

Just change the database name and reconnect.
