从源代码模式安装mysql的问题

1.执行了
configure --prefix=/usr/mysql
make
make install
2.useradd -r mysql
以上步骤，一切正常。
3.但是在执行
/usr/mysql/bin/mysql_install_db时出现提示，不知道应该如何处理？


提示内容：

Installing privilege 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 !
This is done with:
/usr/mysql/bin/mysqladmin -u root password 'new-password'
/usr/mysql/bin/mysqladmin -u root -h www.rhlinux.com password 'new-password'
See the manual for more instructions.

NOTE: If you are upgrading from a MySQL <= 3.22.10 you should run
the /usr/mysql/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 /usr/mysql ; /usr/mysql/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 /usr/mysql/bin/mysqlbug script!

但是在安装目录(/usr/mysql)里没有support-files/mysql.server文件，不知道应该如何处理？


然后执行
mysqld_safe &
提示：
Starting mysqld deamon with databases from /usr/mysql/var

我顶　　　　　　

没有‘mysql’这个用户，用root登陆，作如下工作。

$useradd -M -o -r -d /usr/mysql -s /bin/bash -c "MySQL Server" -u 27 mysql

$chown -R mysql:mysql /usr/mysql　　　　　　

u0u0的答案正确,但是要提醒一下,在第一次启动MYSQL前首先应该进行建库操作:

$mysql_install_db (如果没记错,就是这个命令)
然后再:
$safe_mysql &
