"Host ' ' is not allowed to connect to this MySQL server" 这个错误提示表示主机没有权限连接到MySQL服务器。这通常是由于MySQL的用户权限设置导致的。要解决这个问题,你可以执行以下几个步骤:
1. 确保在MySQL服务器上创建了允许连接的用户账户,并且该账户具有适当的权限。
2. 确认你正在使用正确的主机名或IP地址进行连接。检查你的代码或配置文件中的连接字符串,确保主机名或IP地址是正确的。
3. 检查防火墙设置,确保MySQL服务器端口(默认为3306)未被阻止。
4. 刷新MySQL的权限相关表,以确保更改的权限生效。可以使用以下命令执行刷新操作:FLUSH PRIVILEGES;
完成上述步骤后,你应该能够成功连接到MySQL服务器。

host is not allowed to connect to this mysql server
As an AI language model, I do not have access to your specific server or network settings. However, the error message "host is not allowed to connect to this mysql server" indicates that the MySQL server is not configured to allow connections from the specific host you are trying to connect from.
To resolve this issue, you can try the following steps:
1. Check if the host you are trying to connect from is allowed to access the MySQL server. You can do this by checking the MySQL server's configuration file or by contacting your server administrator.
2. If the host is not allowed, you need to add the host to the list of allowed hosts in the MySQL server's configuration file. This can be done by editing the "my.cnf" file and adding the IP address or hostname of the host.
3. Restart the MySQL server to ensure the changes take effect.
4. Try connecting to the MySQL server again from the host.
If you're still having trouble connecting, you may need to check for firewall issues or other network-related problems. It's best to consult your server administrator or network engineer for further assistance.
host is not allowed to connect to this MYSQL server
这个错误通常表示你的主机没有被授权连接到 MySQL 服务器。这可能是因为你正在使用错误的用户名或密码登录,或者你的 IP 地址没有被授权连接到 MySQL 服务器。
你可以尝试检查你的用户名和密码是否正确,并确保你的 IP 地址已被授权连接到 MySQL 服务器。你可以在 MySQL 服务器上运行以下命令来授权一个 IP 地址连接到 MySQL 服务器:
```
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'IP_ADDRESS' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
```
其中,`USERNAME` 是你的用户名,`IP_ADDRESS` 是你的 IP 地址,`PASSWORD` 是你的密码。如果你想授权所有 IP 地址连接到 MySQL 服务器,可以将 `IP_ADDRESS` 替换为 `%`。
