rpm 으로 설치되어 있던 mysql 을 삭제하고
 mysql-3.23.52.tar.gz 로 다시 설치했습니다.
 다 설치하고 실행을 시키려고
 [root@ns bin]# ./safe_mysqld &
Starting mysqld daemon with databases from /usr/local/mysql/data
021218 15:37:59  mysqld ended
 [root@ns bin]# 
 실행을 했는데.. 실행이 안되더라구요...
 그래서 data 디렉토리를 들어가 보니까
 [root@ns data]# ls
mysql  ns.err  test
[root@ns data]#
 ns.err 이란 파일이 있어 열어봤더니...
 이미 3306 이란 포트가 열어 있다.. 뭐 이런식의 메시지가 나오는 것 같은데..
 이걸 어떻게 해결 해야 할 지 모르겠습니다. 혹시 포트를 다시 막아야 하나요?
 아니면 이전에 rpm 으로 설치한 것을 제대로 지우지 않아서 인가요?
 ns.err
[root@ns data]# cat ns.err
