1 Preface In the previous article (see: Home Data Center Series: Transforming a Retired Mini PC with X-WRT: An Alternative Choice for Main Router), I used an idle J2900 x86 mini PC to tinker with a software router. It ran fine, with performance to spare and a stable system...

1 Preface The main router of my home data center has always been iKuai. Its main advantage is supporting multi-dialing (for the detailed concept of multi-dialing, see the article: ). Since my home Telecom broadband supports up to 3 dials, I can obtain 3 public IPv4 addresses simultaneously, which for someone like me with multi-line access...

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

1 Preface I have always wanted to build a synchronously updated static copy for my WordPress-based dynamic blog. On one hand, it is out of the pursuit of "full-site caching" and "always online" capabilities—after all, in the early days, the blog had not implemented disaster recovery and active-active deployment, and WordPress itself...

1 Preface Previously, 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: utilizing Racknerd...

1 Introduction My previous blog architecture was a home data center (master node + hot standby node) + Tencent Cloud (disaster recovery node), which is a typical "single-node read/write" scheme. Since only the master node handles database read and write requests on a daily basis, real-time synchronization between databases is not required: whenever...

1 Introduction Since purchasing Racknerd's VPS and completing the major project of migrating the disaster recovery node from Tencent Cloud Lighthouse to Racknerd Chicago VPS (see article: Home Data Center Series - The Second Reconstruction of Blog Architecture: Services Triggered by VPS Migration...

1 Introduction Actually, I have always wanted to build a stable, pollution-free DNS service in the local network, specifically to solve the DNS pollution problem, for use by some applications that only need to solve DNS pollution, such as Emby's TMDB plugin, which cannot scrape movie and TV information normally, simply because its A...

1 Introduction As the expiration date of my Tencent Cloud Lighthouse server gets closer and closer, I have been hesitating whether to renew it. The first year was 99 RMB/year, and the second year I remember was 300 RMB/year (I don't remember exactly, around that), but what is the price for the third year? I took a look, and boy: I already felt that the backup...

1 Introduction This article can be considered as me fulfilling a goal I set for myself many years ago. The reason was that when testing the company's anti-DDoS products at that time, I needed to write a user manual for common traffic simulation tools (used to simulate various network attack traffic). I thought: why don't I just write one myself? As a result, it was delayed...
