마리아DB셋팅방법

리눅스 설치 후 버전이 계속 달라지면서 기본세팅값이 바뀐다.

아래 내용중에 필요한것만 찾아서 바꿔주면된다.

보통 검은색으로 BOLD처리한 내용위주로 바꿔주면된다.

최신내용의 conf에 없는 설정은 굳이 찾아서 넣어주지 않아도 잘 작동한다.

설정파일 위치: etc/mysql/mariadb.conf.d/50-server.cnf
 
# MariaDB database server configuration file.
#
# You can copy this file to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
 
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
