先看下用戶列表

①select user,host from mysql.user;?

+------------------+-----------+
| user ? ? ? ? ? ? | host ? ? ?|
+------------------+-----------+
| appleyuchi ? ? ? | localhost |
| debian-sys-maint | localhost |
| mysql.session ? ?| localhost |
| mysql.sys ? ? ? ?| localhost |
| root ? ? ? ? ? ? | localhost |

# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host ? ? = localhost
user ? ? = debian-sys-maint
password = Dk4mVgDGDZFf7rRI
socket ? = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host ? ? = localhost
user ? ? = debian-sys-maint
password = Dk4mVgDGDZFf7rRI
socket ? = /var/run/mysqld/mysqld.sock
?

登錄：

mysql -u debian-sys-maint Dk4mVgDGDZFf7rRI password:Dk4mVgDGDZFf7rRI

③授予權限(下面不要照抄，根據①中的列表中的用戶名和IP來修改)
