Azure Database for MySQL server的“Allow access to Azure services” 参数设置20210430

Allow access to Azure services 

这个参数会控制VNET访问这个mysql。如果是YES, vnet的VM可以访问mysql

如果是NO， 如果VM访问会有提示报错：

ERROR 9009 (28000): Client from Azure Virtual Networks is not allowed to access the server. Please make sure your Virtual Network is correctly configured.

解决的方式是配置vnet service endpoint
