• remove useless requires+after to the same named socket. a .socket will automatically trigger a service if something want to talk to it. you will only ever need to enable the .socket and don't have to explicitly enable the .service in such a scenario. stichwort: triggering units
• add after=mysql.service to not get any silly database errors anymore during boot because the database isn't accessible in the first try. the alias mysql.service was chosen to have a broader compatibility for anyone who isn't using mariadb.

triggering units?

After=mysql is mostly useless. It has no effect if the mysql db used by aapi runs on a remote host, and even for local processes, there is no guarantee that mysql.service is "quick enough" to create its socket before AAPI tries to use it.
