问题描述
为什么哦为什么我连不上mysql?
Why oh why can I not connect to mysql?
mysql -u root -ptest101 -h xxx.xxx.xxx.xxx
ERROR 1130 (HY000): Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MySQL server
在 my.cnf 中有以下内容
In my.cnf I have the below
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 0.0.0.0
我还运行了以下...
'UPDATE mysql.user SET Password = PASSWORD('test101') WHERE User = 'root';
FLUSH PRIVILEGES;
我可以使用 mysql -u root -ptest101 在主机上访问，但不能使用 mysql -u root -ptest101 -h xxx.xxx.xxx.xxx
I can access on the host machine using mysql -u root -ptest101 but not using mysql -u root -ptest101 -h xxx.xxx.xxx.xxx
哇……为什么会这样?我是 ubuntj 12.04
Wow...why is this happening? I am n ubuntj 12.04

推荐答案
您的 root 帐户，此声明适用于任何帐户，可能只添加了 localhost 访问权限(推荐).
Your root account, and this statement applies to any account, may only have been added with localhost access (which is recommended).
您可以通过以下方式检查:
You can check this with:
SELECT host FROM mysql.user WHERE User = 'root';
如果您只看到 localhost 和 127.0.0.1 的结果，则无法从外部源进行连接.如果您看到其他 IP 地址，但不是您所连接的 IP 地址 - 这也是一种指示.
If you only see results with localhost and 127.0.0.1, you cannot connect from an external source. If you see other IP addresses, but not the one you're connecting from - that's also an indication.
您需要添加要授予访问权限的每个系统的 IP 地址，然后授予权限:
You will need to add the IP address of each system that you want to grant access to, and then grant privileges:
CREATE USER 'root'@'ip_address' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'ip_address';
如果您看到 %，那么，还有另一个问题，因为它是任何远程源".但是，如果您确实希望通过 root 连接任何/所有系统，请使用 % 通配符授予访问权限:
If you see %, well then, there's another problem altogether as that is "any remote source". If however you do want any/all systems to connect via root, use the % wildcard to grant access:
CREATE USER 'root'@'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
最后，重新加载权限，您应该可以进行远程访问了:
Finally, reload the permissions, and you should be able to have remote access:
FLUSH PRIVILEGES;
