• 可能遇到的问题

使用本地Navicat 连接服务器上的Mysql总是报“1130-Host ... is not allowed to connect to this MySQL server”错误。

分析：帐号不允许从远程登陆，只能在localhost。

于是到服务器上查看：

mysql> select Host,User,Password  from user order by user;                                               
+-----------------------+---------+-------------------------------------------+
| Host                  | User    | Password                                  |
+-----------------------+---------+-------------------------------------------+
| localhost             |         |                                           |
| localhost             | zachaway | ***************** |
| localhost             | root    | ***************** |
| 127.0.0.1             | root    | ***************** |
+-----------------------+---------+-------------------------------------------+

解决：

# 客户端连接登陆命令后执行
# 如果想让root使用123456从任何主机连接到mysql服务器的话。
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

# 如果允许用户root从ip为10.0.0.0的主机连接到mysql服务器，并使用123456作为密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'10.0.0.0' IDENTIFIED BY '123456' WITH GRANT OPTION;  

# 如果允许用户root从ip为10.0.0.0的主机连接到mysql服务器的ecas数据库，并使用123456作为密码
GRANT ALL PRIVILEGES ONecas.* TO 'root'@'10.0.0.0' IDENTIFIED BY '123456' WITH GRANT OPTION;

FLUSH   PRIVILEGES;

# 查看用户，密码，访问是否受限
select Host,User,Password  from user order by user;
