默认情况下，MySQL服务或者客户端都会读取/etc/my.cnf作为配置文件，除非指定default-file
[mysqld]
port=3306
innodb_file_format=barracuda
innodb_large_prefix=on
lower_case_table_names=1
sql_mode=STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
ma
#
# include all files from the config directory

!includedir /etc/my.cnf.d
[client]
