无法将 Azure 上的 Web 应用程序连接到远程数据库

Question

I deployed a next js web application on to Azure Web App Service , and want to use it to connect to existing remote database, however I am keep getting such error in the log stream:

2021-04-23T18:09:17.315942065Z Error: connect ECONNREFUSED 127.0.0.1:3306

我在应用程序中的数据库连接是：

export const db = mysql.createPool({
    host: 'abcd.efghosting.com',
    port: 3306,
    database: 'pwpush',
    user: 'pwpush_user',
    password: ....,
    multipleStatements: true,
});

不知道为什么它试图连接到127.0.0.1:3306

我试图打开与数据库端点的混合连接之类的东西，但这没有用。

Answer 1

故障排除

1. 检查您使用的是哪个db.js

2. 正确使用混合连接。

创建一个新的混合连接并将端点主机名设置为安装混合连接管理器的实际名称/IP 地址。
