A one-click shell script to set up a CDN node for your websites.

• Build Traffic Server from source.
• Add website to CDN
• Install SSL certificates
• One-click free SSL certificates from Let's Encrypt
• Manage websites, view stats, purge caches...
• Backup configurations (including SSL certificates) and restore on other nodes to quickly deploy multiple CDN nodes
• If you ever used Cloudflare, the CDN nodes created using this script will behave just like Cloudflare servers. They will sit between clients and your origin server, caching content from the origin server, and serving your clients with content. You can set up multiple CDN nodes by running this script on each node, and then use GeoDNS with round robin/failover to build a CDN cluster.

• A freshly installed server, with Ubuntu 20.04 LTS 64 bit, Debian 10/11 64 bit, or CentOS 7/8 64 bit system (see notes for limitations on CentOS 7)
• Do NOT install any web server programs (e.g., Apache, Nginx, LiteSpeed, Caddy). Do NOT install LAMP or LEMP stack. Do NOT install any admin panels (e.g., cPanel, DirectAdmin, BTcn, VestaCP). They are NOT compatible with this script.
• 1 IPv4
• At least 512 MB RAM for running CDN instance
• For the very first time, building the program from source requires about 1.5 GB RAM. You may add SWAP to your VPS for this step.
• Root access, or sudo user

• Firstly, you need to find a spare VPS with at least 1 IPv4, and install Ubuntu 20.04 LTS 64 bit (recommended), Debian 10 64 bit, or CentOS 7/8 64 bit OS.
• Then, please run the following command as a sudo user in SSH.

wget https://raw.githubusercontent.com/Har-Kuun/OneClickCDN/master/OneClickCDN.sh && sudo bash OneClickCDN.sh

• The script will guide you through the installation and configuration process. You will also be prompted to add websites.
• In this process, you will be asked to set up SSL certificate. You can choose to provide paths to your own SSL files (including private key, certificate, and CA chain certificate if applicable), or generate a free Let's Encrypt SSL certificate (not recommended, because if you have more than 1 CDN node, this will not work). If you do choose to use the Let's Encrypt function, make sure to point your domain name to your CDN node IP BEFORE setting up the SSL. You can always set up SSL later by selecting from the main menu.
• You can run the same script again in SSH in order to bring up the menu. It will detect your current installation and will skip the installation process.

sudo bash OneClickCDN.sh

• If you make any changes, please make sure to exit the script by selecting the "0 - Save and quit script" option in the menu. Changes will NOT be effective if you press Ctrl+C to quit the script.
• To uninstall the script and the Traffic Server, please run the following command in SSH.

wget https://raw.githubusercontent.com/Har-Kuun/OneClickCDN/master/uninstall.sh && sudo bash uninstall.sh

Thank you!

Current version: v0.1.0

• TLS 1.3 will NOT work on CentOS 7 because of old OpenSSL version. You can of course compile OpenSSL v1.1.1 manually, but that will potentially break a lot of other things, and is not recommended. If TLS 1.3 is required, please consider using CentOS 8, Ubuntu 20, or Debian 10.
