fbsd的mysql问题

ppboy

fbsd 4.10
ports安装mysql 4.0.23a
安装好后
simon# cd /usr/local/bin
simon# ./mysqld_safe &
[1] 254
simon# Starting mysqld daemon with databases from /usr/local/mysql
STOPPING server from pid file /usr/local/mysql/simon.localdomain.pid
050225 20:32:30  mysqld ended
[1]    Done                          ./mysqld_safe

mysql启动不了,于是

simon# cd /usr/local/etc/rc.d
simon# ./mysql-server.sh start
Starting mysql.
simon#

这样就可以启动!查看前面的出错记录

simon# ee /usr/local/mysql/simon.localdomain.err

050225 20:32:27  mysqld started
050225 20:32:28  InnoDB: Started

050225 20:32:28 Fatal error: Can't open privilege tables: Can't find file: './mysql/host.frm' (errno: 13)

050225 20:32:30  InnoDB: Shutdown completed
050225 20:32:30 /usr/local/libexec/mysqld: Shutdown Complete

050225 20:32:30  mysqld ended

不知道为什么有这样的错误,哪个地方设置错了吗?
