How To Ufw Allow Nginx Http Digital Ocean
Introduction
There are many ways to setup your web hosting on Digital Ocean and one of the recommended ways is to use the Uncomplicated Firewall (UFW) to allow the Nginx web server to access Digital Ocean directly. UFW is a very versatile firewall that can be installed and setup easily, allowing you to securely access your Digital Ocean servers from other locations on the web. In this article we will cover the steps necessary to setup UFW to allow access for Nginx HTTP on Digital Ocean.
Prerequisites
Before we begin, there are a few prerequisites that must be met in order to successfully configure UFW. First, you need to have a system running Ubuntu 16.04 installed on Digital Ocean. It is also recommended that you have a sufficiently sized Digital Ocean droplet to accommodate the size of the web server that you are running. Additionally, you will need to have root access to your Digital Ocean server.
Installing UFW
The first step in configuring UFW is to install the package. This can be done by running the following command:
$ sudo apt-get install ufw
This will install the UFW package, along with all of its dependencies. Once the installation has completed, you can now proceed with configuring UFW.
Enabling UFW
Now that UFW is installed, you can enable it on your system. It is important to note that the default configuration of UFW is to deny all incoming connections. To enable UFW, use the following command:
$ sudo ufw enable
This will enable UFW on your system and start the daemon. You can now proceed with configuring UFW to allow access to Nginx HTTP.
Configuring UFW To Allow Access To Nginx HTTP
Now that UFW is enabled, you can configure it to allow access to the Nginx http server. To do this, we will need to create an “allow” rule that allows incoming traffic from Digital Ocean on port 80 (HTTP) to be routed to the Nginx web server. To do this, you can use the following command:
$ sudo ufw allow from Digital Ocean to any port 80
You should now see that UFW allows incoming connections on port 80 from Digital Ocean. You can also add additional rules to the UFW to allow additional ports, such as port 443 for SSL connections. To verify that UFW is configured correctly, you can run the following command to view your UFW rules:
$ sudo ufw status
You should now see a list of rules that are enabled and applied to your system. You can use this command to check the current status of UFW at any time, and make changes as necessary.
Reloading UFW to Apply Changes
Once you have made the changes to UFW and verified that they are applied correctly, you can reload UFW in order to apply the changes. To do this, use the following command:
$ sudo ufw reload
This will reload UFW and apply the changes. You can now proceed with testing to ensure that Nginx is allowing requests from the Digital Ocean server.
Testing UFW
In order to test that UFW is allowing access to the Nginx web server, you can use a web browser or a tool such as cURL to send a request to the Digital Ocean server. If you receive a valid response, then UFW is correctly allowing access to the Nginx web server.
Conclusion
In this article we covered the steps to configure UFW on Digital Ocean to allow access for Nginx HTTP. We also showed how to verify that your UFW configuration is correct. It is important to remember that UFW is a very versatile firewall and can be used to secure your system from a variety of threats. By understanding the basics of UFW configuration, you can ensure that your system is properly secured and that your Digital Ocean server is as secure as possible.
FAQ
Q: What is Uncomplicated Firewall (UFW)?
A: Uncomplicated Firewall (UFW) is a user-friendly front-end for iptables that is included in many Linux distributions. It allows administrators to more easily configure iptables to allow access to services from specific IPs or provide other security measures.
Q: What ports do I need to open for Nginx HTTP?
A: By default, Nginx HTTP listens on port 80, so you will need to open this port in order for access to be granted from Digital Ocean.
Q: How can I verify that UFW is correctly allowing access?
A: The best way to verify that UFW is correctly allowing access is to send a request to the Digital Ocean server and ensure that a valid response is received.
