刚开始学习Linux，就遇到了问题。

当在RedHat下安装MySQL时提示如下错误，请高手给点指点，谢谢：

rpm -vih  MySQL-server-community-5.0.96-1.rhel5.i386.rpm --nodeps --force

Examine the logs in /var/lib/mysql for more information.
You can try to start the mysqld daemon with:
/usr/sbin/mysqld --skip-grant &
and use the command line tool
/usr/bin/mysql to connect to the mysql
database and look at the grant tables:

shell> /usr/bin/mysql -u root mysql
mysql> show tables

Try ‘mysqld --help‘ if you have problems with paths. Using --log
gives you a log in /var/lib/mysql that may be helpful.

The latest information about MySQL is available on the web at
http://www.mysql.com
Please consult the MySQL manual section: ‘Problems running mysql_install_db‘,
and the manual section that describes problems on your OS.
Another information source is the MySQL email archive.
Please check all of the above before mailing us!
And if you do mail us, you MUST use the /usr/bin/mysqlbug script!
