这个错误通常是由于MySQL服务器的安全设置导致的,它拒绝了来自特定主机的连接请求。解决此问题的方法如下:
1.检查MySQL服务器的防火墙设置,确保允许来自客户端主机的连接请求。
2.检查MySQL服务器的用户权限设置,确保允许来自客户端主机的用户连接请求。
3.检查客户端主机的网络设置,确保它可以与MySQL服务器进行通信。
4.检查MySQL服务器的主机名和IP地址,确保它们正确无误。
5.尝试使用telnet命令测试客户端主机是否可以连接到MySQL服务器。
以下是一个示例,演示如何使用telnet测试MySQL服务器的连接:
```shell
telnet <MySQL服务器IP地址> <MySQL服务器端口号>
```
如果连接成功,则表示客户端主机可以与MySQL服务器进行通信。如果连接失败,则需要检查网络设置和防火墙设置。

1. 主机名或IP地址不正确:请确保使用正确的主机名或IP地址连接到MySQL服务器。
2. 访问权限限制:MySQL服务器可能配置了访问控制列表(ACL),限制了特定主机的连接权限。请检查MySQL服务器的配置文件或联系管理员以获取更多信息。
3. 防火墙阻止连接:防火墙设置可能阻止了来自主机"FZLWOAINI"的连接请求。请检查防火墙设置并确保允许MySQL服务器的连接。
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.
