以上是日志内容，请大咖帮忙看看到底怎么解决

尝试
>./scripts/mysql_install_db --user=mysql --datadir=/www/server/data
运行结果：
Installing MySQL system tables...

Installation of system tables failed!  Examine the logs in
/www/server/data for more information.

You can try to start the mysqld daemon with:

    shell> /www/server/mysql/bin/mysqld --skip-grant &

and use the command line tool /www/server/mysql/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /www/server/mysql/bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /www/server/data that may be helpful.

Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
describes problems on your OS.  Another information source are the
MySQL email archives available at http://lists.mysql.com/.
