How do I enable Cloudflare on my Linode?
In order to enable Cloudflare, follow these steps:
1) Sign up for a Cloudflare account here and add your site's domain name to get started.
2) Wait for Cloudflare to detect current DNS records, and then configure them using Cloudflare's interactive tool.
3) Change the domain's nameservers from Linode's (ns1.linode.com, ns2.linode.com) to the nameservers provided by Cloudflare, and remove any other nameservers specified by Cloudflare. This step needs to be completed with the domain name's registrant (e.g. NameCheap, GoDaddy).
4) Wait for the DNS changes to propagate. This step can take up to 24 hours to complete.
