Managing Virtual Hosts with Nginx in Ubuntu 14.04

In the world of web development, managing multiple websites or applications on a single server is a common requirement. This is where Nginx, a powerful and high-performance web server, comes into play. In Ubuntu 14.04, Nginx is included as the default web server, making it a convenient choice for managing virtual hosts.

Virtual hosts allow you to host multiple websites or applications on a single server, each with its own domain name and configuration. With Nginx, setting up and managing virtual hosts is a straightforward process.

To start, you need to navigate to the Nginx configuration directory, which is located at ‘/etc/nginx/‘. Here, you will find the main configuration file ‘nginx.conf‘, as well as a directory called ‘sites-available‘. Inside the ‘sites-available’ directory, you can create separate configuration files for each virtual host.

To create a new virtual host, simply create a new configuration file in the ‘sites-available’ directory. You can name the file according to your domain name, for example, ‘example.com.conf‘. Inside the file, you will need to define the server block for your virtual host, specifying the listen port, server name, and root directory.

Once you have created the configuration file, you need to enable the virtual host by creating a symbolic link to it in the ‘sites-enabled’ directory. You can do this by running the command ‘sudo ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/‘.

After enabling the virtual host, you can test the Nginx configuration for any syntax errors by running the command ‘sudo nginx -t‘. If there are no errors, you can restart Nginx to apply the changes by running ‘sudo service nginx restart‘.

With the virtual host enabled, you can now access your website or application by entering the domain name in your web browser. Nginx will serve the appropriate content based on the configuration of the virtual host.

Managing virtual hosts with Nginx in Ubuntu 14.04 provides a flexible and efficient solution for hosting multiple websites or applications on a single server. By following the steps outlined above, you can easily set up and manage virtual hosts to meet your specific requirements.
