無法將 Azure 上的 Web 應用程序連接到遠程數據庫

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

我在應用程序中的數據庫連接是：

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

不知道為什么它試圖連接到127.0.0.1:3306

我試圖打開與數據庫端點的混合連接之類的東西，但這沒有用。

Answer 1

故障排除

1. 檢查您使用的是哪個db.js

2. 正確使用混合連接。

創建一個新的混合連接並將端點主機名設置為安裝混合連接管理器的實際名稱/IP 地址。
