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 ip is not allowed to connect to this mysql server
根据提供的引用内容,出现"Host 'IP' is not allowed to connect to this MySQL server"错误的原因是没有授权远程访问MySQL。解决方法如下:
1. 在Linux下运行Spring Boot项目的JAR包时提示IP不允许访问MySQL服务的解决方法:
- 确保MySQL在Windows上配置并且处于启动状态。
- 打开MySQL的配置文件(my.cnf或my.ini)。
- 找到bind-address选项并将其注释掉或更改为0.0.0.0,以允许所有IP地址访问MySQL服务器。
- 保存并关闭配置文件。
- 重启MySQL服务器以使更改生效。
2. 出现"Host 主机名 is not allowed to connect the MySQL server"错误的解决方法:
- 确保MySQL已在Windows上配置并且处于启动状态。
- 在命令提示符(cmd)中运行以下命令:mysql -u root -p
- 如果提示"mysql 不是内部或外部命令",请找到安装MySQL对应的bin文件夹,并在该文件夹中运行mysql.exe。
- 输入MySQL的root用户密码。
- 运行以下命令以授权远程访问MySQL:
```sql
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
```
其中,'password'是你的MySQL root用户密码。
- 退出MySQL命令行界面。
