Preface

With the official completion of the ten-part series of cloudflare tutorials (these ten parts are equivalent to the main series, if there are more in the future, they can only be regarded as extra-partners, and it does not affect the fact that there are only ten parts in the main series~), I think I should open a separate summary post for cloudflare: including the series of tutorials and previous practical articles on various cloudflare functions into a learning map, so that everyone can see the cloudflare-related content more clearly (cloudflare tags can also be quickly classified, but the logic cannot be intuitively reflected). This is also my blog, in addition to the site map, the first learning map sorted out for a certain knowledge system that I think is important.

Cloudflare Tutorial Series

The cloudflare series of tutorials are based on my daily usage experience and are written for the cloudflare overall solution and the important functional modules in the solution. They are tutorials in the form of theory + practice. They are divided into the "Foundation Building" trilogy (mainly introducing the cloudflare overall solution and many important and basic concepts involved), the "Golden Elixir" trilogy (mainly introducing the three functions of WAF, DDoS protection and Cache Rules, which are the three most commonly used basic sets for website building), the "Nascent Soul" trilogy (mainly introducing the three functions of worker, R2 and Zero Trust, which are considered to be cloudflare's more advanced skills) and the final chapter (mainly introducing the various redirections supported by cloudflare).

• Home Data Center Series: From the "core concept and practice" of Cloudflare CDN to accelerate website access, we talk about the "self-selected IP", "preferred IP", and "preferred domain name" that everyone is accustomed to. Although this article does not belong to the series of tutorials, it can be regarded as a summary of the series of tutorials from a higher perspective.

Cloudflare practical summary

The following section is a practical application using one or more functions of Cloudflare, which can also serve as a practical supplement to some functions in the Cloudflare series of tutorials.

• Home data center series uses cloudflare's Origin Rules to solve the problem of having a public IP but no legal ports 80 and 443 when building a website
  In order to solve the problem that when using cloudflare to build a website in China and using the default public IP back to the source, the domain name is not registered, although there is a public IP, there are no 80 and 443 ports. However, this method is no longer recommended. Whether it is domestic home broadband or cloud hosting, it is too dangerous to use cloudflare public IP back to the source: if you still need to use public IP back to the source in China, you should honestly use the registered domain name and use domestic CDN.
• The home data center series uses tunnel technology to allow home broadband without public IP to use cloudflare for free to quickly build a website (recommended)
  This is the recommended way to build a website using domestic equipment (whether it is home broadband or cloud hosting). As long as the tunnel can be established stably, it is the safest way at present, and it does not require the source station to have a public IP.
• Home data center series uses domestic cloud hosting to get free cloudflare to achieve fast access to domestic sites from abroad
  This article was written earlier. In fact, it uses Tencent Cloud host as the origin of Cloudflare (using the public IP back to the source). It is no longer meaningful in China (using foreign cloud hosts is still valid), but it contains detailed steps to migrate the domain name hosted by Tencent Cloud to Cloudflare. Friends in need can refer to it.
• Home Data Center Series Use Cloudflare to create a small mailbox with your own domain suffix
  Very useful. You can use a domain name hosted on cloudlfare to create an email address with your own domain name suffix. It is really a great tool for showing off, but you can only receive messages.
• Home data center series uses cloudflare+resend+gmail to create a free personal business mailbox
  The previous problem that the email with your own domain name suffix can only receive emails has been solved. Now you can also send emails. However, if it is a domestic email provider, there will be a reminder for sending on behalf of others, but there is no problem with entering the inbox.
• Home Data Center Series Reasonable use of cloudflare WARP to improve the speed of accessing websites (desktop version)
  It is no longer suitable for domestic home broadband users, but it still works well abroad.
• Deploy cloudflare warp on the home data center series cloud host to improve network access speed (Linux cli version)
  It is no longer suitable for domestic cloud hosts, but it still works well abroad.
• Home data center series uses github+cloudflare pages to build a new home for www navigation page
  The most basic one is based on github and cloudflare pages, using html templates to host the most basic static pages for free.
• Home data center series uses hexo to build a static blog and deploy it to cloudflare pages
  The advanced version uses hexo to build and host a static blog for free based on github and cloudflare pages.
• Home Data Center Series Use rclone and cloudflare R2 to build Chevereto's remote disaster recovery image bed
  For those who originally used chevereto to build their own image hosting, R2 can be used as the main image hosting that is truly online 24 hours a day, and chevereto can be used as a backup image hosting (part-time watermark tool).
• Home data center series uses cloudflare tunnel to realize automatic takeover of disaster recovery site when WordPress main site fails
  Advanced techniques based on cloudflare tunnel can solve the weaknesses of "home data center": power outages and network disconnection, but this requires the cooperation of the cloud host.
• Home Data Center Series was tragically broken! Recording the first time a blogger was attacked by DDOS, Second attack on home data center series! Optimization of internal blog access process under the new situation, The home data center series stress test was successfully completed! Thanks to my brother for your help, it's now OK!
  The DDoS attack trilogy can be regarded as a practical exercise of Cloudflare's DDoS protection function. However, in addition to Cloudflare's own protection function, it also requires the cooperation of relevant security solutions within the home data center. I will discuss this in a special article in the future.
