    遇见了一个低级的报错，记下来：

[root@ZHANGLIN bin]# ./mysql -root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 87506
Server version: 5.6.19 Source distribution

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

mysql> show databases;
Ignoring query to other database
mysql> use mysql;
Database changed
mysql> show tables;
Ignoring query to other database
mysql>

出现这个是因为登录MySQL的时候，没有加上 'u'  也就是  -uroot 。
