If we have a cloud server with a medium or high specification, we can host multiple web apps in it with different domain names for each app. If we need to host a web app backend on any cloud server, it does require an HTTP web server. The most popular HTTP servers available are Apache and NGINX.
The Apache HTTP Server, colloquially called Apache, is a free and open-source cross-platform web server, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. Now, Apache2 is used mostly.
NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. NGINX is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.
You can select either Apache2 or NGINX. Anyways I am covering both the technologies in this tutorial.
Let’s come to the topic.
APACHE2
Let us first take a look at the Apache2 configuration for hosting multiple websites.
Configure virtual host in Apache2
We need to configure the virtual host in Apache2 to handle multiple domain requests coming to the Apache server.
The configuration file can be found in the destination
/etc/httpd/conf/httpd.conf
Here I am configuring my Apache2 virtual host for two domains syamlal.com and techomoro.com as I show below. You have to change the value for ServerAdmin, DocumentRoot, ServerName, ErrorLog, CustomLog based on your requirement.
<VirtualHost *:80> ServerAdmin contact@techomoro.com DocumentRoot /var/www/html/techomoro ServerName techomoro.com ErrorLog logs/techomoro.com-error_log CustomLog logs/techomoro.com-access_log common </VirtualHost> <VirtualHost *:80> ServerAdmin hi@syamlal.com DocumentRoot /var/www/html/syam ServerName syamlal.com ErrorLog logs/syamlal.com-error_log CustomLog logs/syamlal.com-access_log common </VirtualHost>
Now we need to restart the Apach2 server.
sudo service apache2 restart
NGINX
Now we can try this with NGINX configuration.
Configure virtual host in NGINX
We need to configure the virtual host in NGINX to handle multiple domain requests coming to the NGINX server.
The configuration file can be found in the destination
/etc/nginx/conf.d/virtual.conf
Here I am configuring my NGINX virtual host for two domains syamlal.com and techomoro.com as I show below. You need to change the value for root and server_name based on your requirement.
server {
listen 80;
root /var/www/html/techomoro;
index index.html index.htm;
server_name techomoro.com;
location / {
try_files $uri $uri/ =404;
}
}
server {
listen 80;
root /var/www/html/syam;
index index.html index.htm;
server_name syamlal.com;
location / {
try_files $uri $uri/ =404;
}
}
Now we need to restart the NGINX server.
sudo service nginx restart
Summary
Here in this article, we discussed the steps to host multiple websites on a single cloud server with Apache2 or NGINX.
