how to run different node app on server different domains

Running Different Node Apps on Different Domains

If you want to run different Node apps on different domains, you can accomplish this in several ways. One way is by using virtual hosting on your server. Virtual hosting allows you to host multiple domains on a single server and run different Node apps on each domain.

Step 1: Set up Virtual Hosts

To set up virtual hosts, you need to create a new configuration file for each domain you want to host. You can do this by creating a new file in the /etc/apache2/sites-available/ directory:

sudo nano /etc/apache2/sites-available/mydomain.com.conf

Replace mydomain.com with the actual domain name you want to use. In this file, you need to specify the following:

• The domain name
• The document root (where your Node app is located)
• The Node app to run

Here's an example configuration file:

<VirtualHost *:80>
    ServerName mydomain.com
    DocumentRoot /var/www/mydomain.com
    <Directory /var/www/mydomain.com>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ProxyPass / http://127.0.0.1:3000/
    ProxyPassReverse / http://127.0.0.1:3000/
</VirtualHost>

In this example, we're running a Node app on port 3000. The ProxyPass and ProxyPassReverse directives tell Apache to forward requests to this port when a user visits the domain.

Once you've created this file, you need to enable the virtual host:

sudo a2ensite mydomain.com.conf

This command creates a symbolic link to the /etc/apache2/sites-enabled/ directory, which makes the virtual host active.

Step 2: Start Your Node Apps

Next, you need to start your Node apps. You can do this by running the following command in your app directory:

node app.js

This will start your Node app on the default port (usually 3000).

Step 3: Restart Apache

Finally, you need to restart Apache to apply the changes:

sudo service apache2 restart

Now you should be able to visit your domains and see your Node apps running!
