Let us learn how to do the cloudflare argo tunnel setup with the support of our Server management support services at Bobcares.

How to Configure CloudFlare Argo Tunnel on Linux?

Cloudflare’s lightweight Argo Tunnel daemon establishes an encrypted tunnel between the origin web server and the nearest Cloudflare data center, all without opening any public incoming ports.

After the firewall has blocked all origin server ports and protocols, any HTTP/S requests, including volumetric DDoS attacks, are dropped.

Data breach efforts, such as data spying in transit or brute force login assaults, are completely prohibited.

Argo Tunnel secures and encrypts application traffic to any sort of infrastructure rapidly, allowing us to focus on delivering outstanding apps.

We can now encrypt origin traffic and mask the web server IP addresses, preventing direct assaults.

Cloudflare Argo Tunnel Setup

Follow the steps given below to setup the Argo Tunnel:

1. Firstly, get the Cloudflare package here.

   

   Note this is on CnetOS

   On Ubuntu

   
2. Download and install the cloudflared __package.

   On CentOS do the following:

   

   For Ubuntu do the following:

   
3. After installing, check the version to ensure that cloudflared was correctly installed.

   

   On port 7844/TCP, the cloudflared daemon connects to the cloudflare network. As a result, open 7844/TCP Outbound in the Firewall.
4. The first step is to sign in to the Cloudflare account using cloudflared. When we run the following command, a login page should appear in the browser.

   If the browser does not open automatically, copy and paste the URL into the address bar of the browser and press enter.

   /usr/local/bin/cloudflared tunnel login
5. We will see a list of domains linked with the account after we log in. Find the domain to which we want to connect a tunnel and click its name in the table row.

   When we choose a domain, Cloudflare will install a certificate to authenticate the system to the Cloudflare network.

   We’ll get a Success message in the browser once cloudflared has installed the certificate, and we’ll be able to use cloudflared and Argo Tunnel!

Configure Argo Tunnel​

• Argo Tunnel creates a virtual, encrypted tunnel between a local web server and the Cloudflare network.

  Tunnel produces DNS records for us automatically; we may select a subdomain that does not yet have anything running or configured.

  
• Argo Tunnel may be installed as a system service on Linux. Create the cloudflared directory and copy the already-fetched certificate file.

  
• Add the following text to the cloudflared configuration file /etc/cloudflared/config.yml.
• Direct traffic to the Web Server.

  
•  Within Cloudflare, we may establish a Load Balancer that will send traffic to Argo Tunnels that have been created on several servers or even continents.

  This is the preferred method for deploying high-availability tunnels in production, allowing us to take advantage of all of the strong capabilities offered by Cloudflare Load Balancing.

  
• Finally, we have to check whether if the Argo tunnel is running or not by typing in the following line:

  sudo ps -aux | grep tunnel
