# NOTE: This file is read only by the traditional SysV init script, not systemd. # MariaDB systemd does _not_ utilize mysqld_safe nor read this file. # # For similar behaviour, systemd users should create the following file: # /etc/systemd/system/mariadb.service.d/migrated-from-my.cnf-settings.conf # # To achieve the same result as the default 50-mysqld_safe.cnf, please create # /etc/systemd/system/mariadb.service.d/migrated-from-my.cnf-settings.conf # with the following contents: # # [Service] # User=mysql # StandardOutput=syslog # StandardError=syslog # SyslogFacility=daemon # SyslogLevel=err # SyslogIdentifier=mysqld # # For more information, please read https://mariadb.com/kb/en/mariadb/systemd/ # [mysqld_safe] # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # especially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location. socket = /var/run/mysqld/mysqld.sock nice = 0 skip_log_error syslog
