mysql 설치 후 디렉토리 변경해서 시작하면 에러가 발생 합니다.

centos에서 mysql을 yum으로 설치했습니다.

설치 후에 my.cnf 파일의 mysql 경로를 변경 했구요.

물론 설치후에

mysql_install_db && chown -R mysql:mysql /home/bumworld/program/mysql

이렇게 해줬습니다.

그리고 /etc/rc.d/init.d/mysqld start

위와같이 mysql을 시작했는데 실패를 해서 로그를 보니 아래와 같이 권한 문제가 있는듯 한데요.

분명히 디렉토리 권한을 제대로 주고 확인도 했습니다.

어떤 이유때문에 계속해서 발생하는지 모르겠습니다.
(여러번 지우고 새로 설치도 해봤습니다.)

도움부탁드려요..ㅠ.ㅠ
