1 Introduction In the previous article (see: Home Data Center Series: Using X-WRT to Transform Retired Small Hosts: An Alternative Choice for Main Routers), I used an idle J2900 x86 small host to tinker with the soft router. It worked fine, the performance was more than adequate, and the system was stable...

1 Introduction I have always used iQuick as the main router in my home data center. Its main advantage is that it supports multi-dial function (for the detailed concept of multi-dial, please refer to the article:). Because my home telecom broadband supports up to 3 dials, I can obtain 3 public network IPv4 addresses at the same time, which is very useful for people like me who have multiple line access...

1 Introduction When deploying a WordPress multi-active node solution, a crucial technical point is read-write separation: that is, all operations involving "writing to the database" (such as publishing articles, modifying content, modifying plugin configuration, submitting comments, etc.) are uniformly routed to the primary write node for completion, while other nodes...

1 Introduction I have always wanted to build a synchronously updated static copy for a dynamic blog based on WordPress. On the one hand, it is out of the pursuit of "full site cache" and "always online" capabilities - after all, early blogs have not yet achieved disaster recovery and dual-active deployment, and WordPress itself...

1 Preface Before, I wrote an article about dnscrypt-proxy deployment (see: dnscrypt-proxy (v2.1.8) multi-scenario configuration guide: from upstream deployment to downstream integration). The architecture at that time was: using Racknerd…

1 Introduction My previous blog architecture is a home data center (master node + hot standby node) + Tencent Cloud (disaster recovery node), which is a typical "single node read and write" solution. Since only the master node is responsible for processing database read and write requests on a daily basis, there is no need for real-time synchronization between databases: every time...

1 Introduction Since I purchased Racknerd's VPS and completed the big project of moving the disaster recovery node from Tencent Cloud's lightweight server to Racknerd's Chicago VPS (see article: The second reconstruction of the home data center series blog architecture: service issues caused by VPS relocation...

1 Introduction Actually, I have always wanted to build a stable and pollution-free DNS service in the intranet, specifically to solve the DNS pollution problem, for some applications that only need to solve DNS pollution, such as emby's tmdb plug-in, which cannot scrape film and television information normally, just because its A...

1 Introduction As the expiration date of Tencent Cloud Lightweight Server is approaching, I have been hesitating whether to renew it. The first year was 99 yuan/year, and the second year I remember was 300 yuan/year (I don’t remember clearly, about that), and what is the price for the third year? I took a look and saw that: I thought the backup…

1 Introduction This article is the fulfillment of a goal I set for myself many years ago. The reason is that when I was testing the company's anti-D product, I needed to write a manual for a common traffic simulation tool (used to simulate various network attack traffic), so I thought: I might as well write one. As a result, I delayed it...
