# Multi instance version of mariadb. For if you run multiple versions at once. # # create config file /etc/my.cnf.d/my{instancename}.cnf to be used as the # configuration file for this service. # # start as systemctl start mariadb@{instancename}.server # # It's not recommended to modify this file in-place, because it will be # overwritten during package upgrades. If you want to customize, the # best way is to create a file "/etc/systemd/system/mariadb@.service", # containing # .include /usr/lib/systemd/system/mariadb@.service # ...make your changes here... # or create a file "/etc/systemd/system/mariadb@.service.d/foo.conf", # which doesn't need to include ".include" call and which will be parsed # after the file mariadb@.service itself is parsed. # # For more info about custom unit files, see systemd.unit(5) or # https://mariadb.com/kb/en/mariadb/systemd/ # # Copyright notice: # # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or # (at your option) any later version.
