우선 alpine의 패키지 관리자 apk를 사용해서 mysql을 설치했다.
/ # apk update && apk add mysql
여기까지 설치하면 mysql 서버까지만 설치가 완료된다. 잘 동작하는지 확인해보기 위해 클라이언트까지 설치해본다.
/ # apk add mysql-client
아래처럼 mysql 명령어로 클라이언트에 접속해보려하면 에러가 발생한다.
/ # mysql
ERROR 2002 (HY000): Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)
mysql 서버가 실행중이지 않아서 생긴 문제같다. mysqld 명령어로 데몬서버를 실행시켜본다. 그런데 아래와 같이 문제가 발생한다.
/ # mysqld &

디렉토리가 생성되어 있지 않아서 생긴 문제같다. 직접 디렉토리를 생성해주고 다시 데몬서버를 실행시켜본다. 그러면 아래와 같이 문제가 발생한다.

정확한 원인은 잘 모르겠지만, 관련해서 서치해본 결과 mysql_install_db로 초기화가 필요한 문제같다. 아래와 같이 초기화하고 난 후 실행시켜봤다. 그런데 port가 0으로 설정되는 문제가 생겼다.

일단 실행중인 mysqld의 프로세스를 kill해주고 mysql의 설정파일을 수정해서 다시 실행해주니 잘 동작했다. 설정파일을 아래와 같은 방법으로 수정했다.
/ # cat > /etc/my.cnf
# This group is read both both by the client and the server
# use it for options that affect everything
[client-server]
# This group is read by the server
[mysqld]
socket = /run/mysqld/mysqld.sock
datadir = /var/lib/mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# include all files from the config directory

드디어 잘 동작하는 모습이다.
