我从这个位置下载 的mysql ，解压后，用 ./configure 的时候，他提示我不用任何配置，就可以用了。。。为什么不用编译就可以用呢，并且他用的数据目录是 /var/lib/mysql 如下：

[root@localhost mysql-standard-5.0.27-linux-i686]# ./configure --prefix=/usr/local/mysql
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.

Installing all prepared tables
Fill help tables

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.

NOTE:  If you are upgrading from a MySQL <= 3.22.10 you should run
the ./bin/mysql_fix_privilege_tables. Otherwise you will not be
able to use the new GRANT command!

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!

Starting the mysqld server.  You can test that it is up and running
with the command:
./bin/mysqladmin version
