当我尝试运行使用 cpanel 的节点应用程序时出现错误 500 但那是运行在 cpanel 中的终端上工作

Question

我将发送一些代码片段，因为我认为它可以帮助那些愿意帮助我的人。当我在 Cpanel 中通过 node.js 启动应用程序并通过 url 域获得访问权限时，它陷入错误 500 但是当我通过 Cpanel 终端启动应用程序并通过 IP 访问时：端口应用程序工作。

mongoose.connect("mongodb://127.0.0.1:27017/transparenciaBarrinha", { useNewUrlParser: true });
app.get("/receitas",(req,res)=>{
    Receitas.find({},(err,receitas)=>{
        if(err){
            console.log(err);
        }else{
            res.render("receitas", { receitas: receitas })
        }
    })
});
app.listen(50000,()=>{
    console.log("Running on port: 50000");
});

我有更多代码，但都是一样的，我检查了文件，它们可以正常工作。我去报错界面发现了这个，如果重复几次，就有100多个这样的报错行，我觉得是程序没有权限保存日志的问题

Answer 1

这里的问题就在第一行。

您正在 localhost 上连接到 mongodb，而不是连接到远程数据库。

只有在 vps 上正确设置自己的 mongodb 实例才有可能，这有点棘手，请考虑 Mongo Cloud 的免费版本：

https://www.mongodb.com/

Answer 2

始终注意您在应用程序中使用的端口运行，浏览器通常使用 80 或 443，但这些端口很忙，我使用的是 50000，所以当我插入 link错了。
