changing my.ini file bind address to 0.0.0.0 将my.ini文件绑定地址更改为0.0.0.0
creating user and granting permission by GRANT ALL PRIVILEGES ON DATABASE.* TO user@'%' IDENTIFIED BY 'password'; 通过授予GRANT ALL PRIVILEGES ON DATABASE.* TO user@'%' IDENTIFIED BY 'password';创建用户并授予许可GRANT ALL PRIVILEGES ON DATABASE.* TO user@'%' IDENTIFIED BY 'password';
from command line to windows MySQL server mysql -h windows server ip -u user -p 从命令行到Windows MySQL服务器mysql -h windows server ip -u user -p

it works fine and from MySQL workbench i am able to connect for windows MySQL server from my machine. 它工作正常，并且可以从MySQL工作台从我的机器连接Windows MySQL服务器。 BUT when in Linux virtual machine i have done the same thing 但是在Linux虚拟机中我做过同样的事情

1 个解决方案

First, try to connect to the database on the VM hosting the database. 首先，尝试连接到托管数据库的VM上的数据库。 If the connection is successful, then the configuration of the database is correct. 如果连接成功，则数据库的配置正确。 Otherwise, please check the configuration of your database. 否则，请检查数据库的配置。

Second, if you are able to connect to database on the VM, then the most possible cause of this issue is firewall. 其次，如果您能够连接到VM上的数据库，则此问题的最可能原因是防火墙。 Please check if the local firewall (iptables) allows inbound connection on port 3306. For test purpose, you may disable the firewall temporarily. 请检查本地防火墙（iptables）是否允许端口3306上的入站连接。出于测试目的，您可以暂时禁用防火墙。 Also, please check if the NSG has been configured properly to allow the inbound traffic on port 3306. 另外，请检查NSG是否已正确配置为允许端口3306上的入站流量。

Besides, if the VNET has been associated with a NSG, then we need to allow the inbound traffic in the NSG too. 此外，如果VNET已与NSG关联，那么我们也需要允许NSG中的入站流量。
