간략한 소개
- mysql을 포크 따서 만든 데이터베이스
- 높은 성능과 안정성을 자랑하며, 오픈소스로 제공됨
1. test : 순수 데비안
- 순수한 데비안을 도커 위에 올린다.
- mariadb를 깐다. (하단 명령어 실행 시 자동실행)
- 도커 안으로 들어간다. (하단 명령어 실행 시 자동접속)
- 설정파일을 찾아본다.
bash
docker run -it debian:buster
-----
cd etc/mysql
cat my.cnf
bash
# The MariaDB/MySQL tools read configuration files in the following order:
# 1. "/etc/mysql/mariadb.cnf" (this file) to set global defaults,
# 2. "/etc/mysql/conf.d/*.cnf" to set global options.
# 3. "/etc/mysql/mariadb.conf.d/*.cnf" to set MariaDB-only options.
# 4. "~/.my.cnf" to set user-specific options.
bash
mysql --help
# Default options are read from the following files in the given order:
# /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
# The following groups are read: mysql client client-server client-mariadb
# The following options may be given as the first argument:
설정파일의 종류 : .cnf 파일
어디로 복사해야 하는가? /etc/mysql/mariadb.conf.d/50-server.cnf
2. 느낌 잡아보기
- 도커에 깐다
- 쉘 스크립트를 설정
- 설치되어 있는지 판단
- 되어있지 않으면, SQL 구문을 입력
- DB의 기반을 제작
- 이걸 복사한다
- 쉘 스크립트를 실행
3. 실제 쉘 스크립트

# When running under systemd, error logging goes via stdout/stderr to journald

# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
# Most important is to give InnoDB 80 % of the system RAM for buffer use:

# this is only for embedded server
[embedded]
# This group is only read by MariaDB servers, not by MySQL.
# If you use the same .cnf file for MySQL and MariaDB,
# you can put MariaDB-only options here
[mariadb]
# This group is only read by MariaDB-10.5 servers.
# If you use the same .cnf file for MariaDB of different versions,
# use this group for options that older servers don't understand
