+# Multi instance version of MariaDB
+#
+# Use this if you run multiple instances of MariaDB on a single server.
+#
+# This systemd service is not suitable for Galera as specialised SST recovery
+# scripts are needed.
+#
+#
+# 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/

+# MULTI INSTANCES
+#
+# When multiple instances of MariaDB are running on a server they need to
+# ensure that they don't conflict with each other. This includes elements
+# like network ports, sockets and data directories listed under CONFLICTING
+# VARIABLES below. The systemd environment variable MYSQLD_MULTI_INSTANCE
+# controls each instance to ensure it is run independently. It is passed to
+# mariadbd and mysql_install
+#
+# By default, a group suffix exists and within the default configuration
+# files, a group [mariadbd.{instancename}] is read for each service. Other
+# default groups, like [server.{instancename}] and [mariadb.{instancename}],
+# are also read. For each instance, one of the groups will need to contain
+# the conflicting variables listed below under CONFLICTING VARIABLES.
+#
+# The MYSQLD_MULTI_INSTANCE environment used is:
+#    Environment='MYSQLD_MULTI_INSTANCE=--defaults-group-suffix=.%I --basedir=@prefix@'
+#
+#
+# APPLYING YOUR MULTI INSTANCE MECHANISM
+#
+# To apply one of the non-default multi-instance mechanisms, create a file
+# "/etc/systemd/system/mariadb@.service.d/multi.conf" containing:
+#
+#   [Service]
+#   Environment=MYSQLD_MULTI_INSTANCE="...."
+#
+# Include any other settings you which to override. Directives like Exec* are
+# lists and adding a directive will append to the list. You can clear the list
+# by starting with "Directive=" and no value. Follow this by the list that you
+# do want. See the systemd.unit(5) manual page for more information.
+#
+# Then run "systemctl daemon-reload".
+#
+#
+# EXAMPLE MYSQLD_MULTI_INSTANCE CONFIGURATIONS
+#
+# Configuration File Based Mechanism:
+#
+# This has a configuration file per instance.
+#
+#   [Unit]
+#   ConditionPathExists=@sysconfdir@/my.%I.cnf
+#
+#   [Service]
+#   Environment=MYSQLD_MULTI_INSTANCE=--defaults-file=@sysconfdir@/my.%I.cnf
+#
+# Here you need to create a configuration file @sysconfdir@/my.%I.cnf for each
+# instance, each containing the conflicting variables to separate instances.
+#
+#
+# Multi User Based Mechanism:
+#
+# Here each user (the instance name) has their own mysql instance.
+#
+# Create instances in users home directory with abstract socket:
+#
+#   [Service]
+#   User=%I
+#   ProtectHome=false
+#   ExecStartPre=
+#   ExecStartPre=@scriptdir@/mysql_install_db $MYSQLD_MULTI_INSTANCE \
+#       --auth-root-authentication-method=socket --auth-root-socket-user=%I
+#   Environment=MYSQLD_MULTI_INSTANCE="--defaults-file=/home/%I/my%I.cnf \
+#       --datadir=/home/%I/mysqldatadir --skip-networking --socket=@mysql-%I"
+#
+#
+# Command Line Mechanism:
+#
+# This is a good way run multiple instance where there is little difference
+# in configuration between instances.
+#
+#   [Service]
+#   Environment=MYSQLD_MULTI_INSTANCE="--socket=/run/mysqld/%I.sock \
+#                        --datadir=/var/lib/mysqld-multi/%I \
+#                        --skip-networking"
+#
+#
+# CONFLICTING VARIABLES
+#
+# A number of MariaDB system variables may conflict. The main ones that need to
+# be set because their default values will conflict are:
+#   * socket
+#   * port
+#   * datadir
+#
+#
+# PRE-10.4
+#
+# Before 10.4 MYSQLD_MULTI_INSTANCE was effectively --defaults-file=@sysconf2dir@/my%I.cnf
+# As @sysconfdir@/my.cnf included these files it was a bad choice as an
+# existing single instance would include all these files. If you want to
+# continue a file based multi-instance mariadbd, recommend the Configuration File
+# Based Mechanism above and moving @sysconf2dir@/my%I.cnf files to @sysconfdir@/my%I.cnf.
+#
+#
+# SELINUX
+#
+# As basic selinux rules are written around a single instance of MariaDB you may need
+# to define labels for the files and network ports of all instances.
+#
+# See: https://mariadb.com/kb/en/library/what-to-do-if-mariadb-doesnt-start/#selinux
+#
+#

+#
+# Start the instance: systemctl start mariadb@{instancename}.service
