이렇게 하면 mysql 의 데이터 디렉토리(data)에 생기는 로그 파일인 mysql-bin.000001 (숫자)파일이 평소에 mysql을 구동하는 계정이 아닌 root 계정 것으로 생긴다. 이런 일을 예방하려면 --user=root 가 아니라 mysql 서버를 구동하는 계정 이름(가령, --user=mysql 등)으로 위 절차를 실행해야 한다.
이미 그런 일을 벌였다면 문제를 일으키고 있는 로그 파일의 소유자를 mysql 을 구동하는 계정으로 만들어 줘야 한다.

when i start mysql with command ''./mysql.server start'' I got this error Manager of pid file quit without updating pid file. I thoroughly search for the solution to fix this error but cannot resolve it yet. The root cause could be a variety of things, for example file permissions problems in your datadir, or the config file contained an invalid line, or dozens of other possible problems.
I copied file to the /etc directory and rename it by also edited this file in the section ''The mysql Server'' and add these lines ''datadir = /exports/disk0/data'' but could fix this problem. When you get the error about the pid file, the first thing you should do is to go read the My SQL error log file.
