How To Configure Nginx With Varnish

Introduction

Nginx and Varnish are powerful web server tools used to configure and optimize the delivery of web content. Nginx serves requests while Varnish caches and serves requests. This walk-through will help you understand the value of combining the two and how you can configure Nginx with Varnish on Ubuntu.

What is Nginx?

NGINX is a cross-platform web server software developed by a Russian software company called Nginx. It is used for websites, web apps, streaming media, and load balancing. Nginx is widely used to deliver large amounts of data quickly and consistently. In comparison to other web servers, Nginx is more secure and faster.

What is Varnish?

Varnish is a caching web accelerator that improves the performance of web applications by caching static content from web servers. It stores frequently accessed content in memory, reducing the need to fetch data from a web server or database each time a page is loaded. This dramatically increases the speed of web applications.

Nginx and Varnish Configuration

Once installed, Nginx and Varnish can be configured together according to your specific needs. Here are the steps you need to follow to configure Nginx with Varnish.

1. Install Nginx

The first step is to install Nginx. To do this, you will need to use the command line interface (CLI). Enter the command “sudo apt-get install nginx”. This command will install Nginx on your system.

2. Configure Nginx

Once Nginx is installed, you will need to configure it. To do this, you will need to edit the Nginx configuration file. This file is located at “/etc/nginx/nginx.conf”. To edit this file, use the command “sudo nano / etc/nginx/nginx.conf”. Make any necessary change you need to make in the configuration file and save it.

3. Install Varnish

The next step is to install Varnish. To do this, enter the command “sudo apt-get install varnish”. This will install Varnish on your machine. Once installed, you will need to configure Varnish. To do this, edit the Varnish configuration file. This file is located at “/etc/varnish/default.vcl”.

4. Configure Varnish

To configure Varnish, you will need to edit the Varnish configuration file. Use the command “sudo nano /etc/varnish/default.vcl”. This command will open the Varnish configuration file. Make any necessary change you need to make in the configuration file and save it. Once you have saved the file, you will need to restart Varnish. To do this, use the command “sudo service varnish restart”.

5. Configure Nginx and Varnish

The final step is to configure Nginx and Varnish to work together. To do this, you will need to edit the Nginx configuration file. Use the command “sudo nano /etc/nginx/nginx.conf”. This command will open the Nginx configuration file. In this file, you will need to add a line that tells Nginx to forward requests to Varnish. The line should look like this: “proxy_pass http://localhost:8080”. Make sure to save the file when you are done.

6. Testing the Configuration

Once you have configured Nginx and Varnish, you can test the configuration by making a request to your web server. To do this, you can use the command “curl [your_web_server]”. This command will make a request to your web server and you should see the response from Varnish.

Conclusion

By following the steps above, you can easily configure Nginx and Varnish on an Ubuntu system. This combination of web server tools will help you improve the speed and performance of your web applications. Additionally, these tools can be configured to match your specific needs.
