两个域名可以绑定一个空间

<VirtualHost *:80>
    ServerName domain1.com
    DocumentRoot /var/www/domain1
</VirtualHost>

<VirtualHost *:80>
    ServerName domain2.com
    DocumentRoot /var/www/domain2
</VirtualHost>

server {
    listen 443 ssl;
    server_name domain1.com;

    ssl_certificate /path/to/domain1.crt;
    ssl_certificate_key /path/to/domain1.key;

    location / {
        root /var/www/domain1;
    }
}

server {
    listen 443 ssl;
    server_name domain2.com;

    ssl_certificate /path/to/domain2.crt;
    ssl_certificate_key /path/to/domain2.key;

    location / {
        root /var/www/domain2;
    }
}

const express = require('express');
const app = express();

app.use((req, res, next) => {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
    next();
});

app.get('/', (req, res) => {
    res.send('Hello World!');
});

app.listen(3000, () => {
    console.log('Server running on port 3000');
});
