求助，linux下安装mysql的问题

我将mysql安装文件解压到www/mysql下，
运行./configure配置的时候报错误如下
NOTE: This is a MySQL binary distribution. It's ready to run, you don't
need to configure it!

To help you a bit, I am now going to create the needed MySQL databases
and start the MySQL server for you.  If you run into any trouble, please
consult the MySQL manual, that you can find in the Docs directory.

To start mysqld at boot time you have to copy support-files/mysql.server
to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
See the manual for more instructions.

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:
cd sql-bench ; perl run-all-tests

Please report any problems with the ./bin/mysqlbug script!

with the command:

mysql服务启动不了，请问该怎么解决，谢谢了　　　　　　

It's ready to run!
（MySQL）已经运行了。也就是说，你的系统中已经有一个MySQL正在运行，我想是那个系统默认安装的MySQL正在运行，并且占用了/var/lib/mysql下的库。
方法一，卸载系统内的MySQL和var/lib/mysql。
方法二，将你源码安装的MySQL的库另外放置，怎么放看安装目录下的INSTALL。　　　　　　

较新的mysql版本(mysql 4 或5 版)已经不用运行./configure
按照目录下的INSTALL-BANIRY文件说明进行安装
