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 `%`。
