登入MySQL的时候，你是可以选择交互式或者将密码指定出来从而直接登录两种方式的：
1.交互式：

[root@rhel71 ~]# mysql -uroot -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
[root@rhel71 ~]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 17
Server version: 5.7.7-rc-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

[root@rhel71 ~]# mysql -uroot -p

Enter password:

[root@rhel71 ~]# mysql -uroot -p

Enter password:

2.非交互：

非交互的方式下，密码会明文的显示在终端上。
这样子带来的安全隐患是显而易见的。
但是为了防止用户忽视，MySQL依旧还是指出来了：
mysql: [Warning] Using a password on the command line interface can be insecure.
