安装完mysql后用root不能su成mysql
现象：debian的机器用aptitude install mysql-server-5.1 后，用id
mysql 可看出已经建了mysql用户，但是用root来su mysql 不成功，/var/log/auth.log显示：Mar 2 22:23:15
mhxy-db08 su[26669]: pam_unix(su:session): session opened for user mysql by
andrew(uid=0) Mar 2 22:23:15 mhxy-db08 su[26669]: pam_unix(su:session): session
