当我尝试使用cpanel运行节点应用程序时出现错误500，但这是在cpanel的终端上运行

Question

我将发送一些代码片段，因为我认为它可以帮助谁将帮助我。当我在Cpanel中通过node.js启动应用程序并通过url域访问时，它陷入错误500，但当我通过Cpanel终端启动应用程序并通过IP: port访问时，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");
});

我有更多的代码，但这是一样的事情，我检查了文件，他们都在工作。我转到错误屏幕，发现如果它重复几次，就会有100多行这样的错误行，在我看来，这是程序没有权限保存日志的原因

Answer 1

总是注意你在应用程序中运行的端口，通常浏览器使用80或443，但这些都很忙，我使用的是50000，所以当我插入链接时，链接是错误的。

Answer 2

这里的问题在第一行。

您正在连接到localhost上的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，请考虑使用免费版本的Mongo Cloud：
