Preface: In some special scenarios, we may need our own controllable DNS server. For example, setting up an experimental environment in an intranet requires a custom test domain name. In this case, you only need to point the DNS server of the test machine to the controllable DNS (when there are many test machines, you can't go and change each one...
Preface: Having some free time and feeling that a home data center should at least have an email address with its own domain name suffix, I decided to build a mail server myself. Regarding the choice of software, I investigated a lot. First, I looked into EwoMail, but the official recommendation was CentOS 7/8, so I installed CentOS...
Preface: Currently, fewer and fewer newly installed home broadband connections have public IPv4 addresses, replaced by more and more public IPv6 addresses. However, because IPv6 addresses are difficult to remember and many friends lack solutions for public IPv6 addresses and dynamic domain name binding at home, it leads to...
Preface: Actually, I didn't want to write this article at first. I'm always too lazy to write about things that can be easily found all over the internet. But then I thought, taking this as an opportunity, I would record the process of building an application (mainly including the reuse of the database) from beginning to end, so that in the future when I need it, I can just: ...
Building a home data center involves numerous applications. This article takes my home environment as an example to sort out the applications that need to be used for your reference. Personal Blog: The release of my home data center applications is a cluster of sites with the personal blog as the main body. For building the personal blog, I chose WordP...
1 Preface: When we use Linux systems, a common requirement we often encounter is the need to run commands (or scripts) at startup. This article takes running the Tailscale relay server DERP at startup on Debian 11 as an example to summarize the 3 most common ways to run at startup...
1 Preface: Because Tailscale does not have an official relay server in China (for reasons you know), although it is basically still usable (using foreign relays), the latency display is very high. Moreover, deep down, public relay servers are annoying (sharing underwear with everyone?)...
Preface: In the previous article, I built my own simple COS platform using MinIO in Docker (see: Docker Series: Building a Private COS Platform Based on MinIO). This was originally something I occasionally used to share some large files with friends. However, because...
Preface: When we usually want to share a file with a friend, it generally comes down to the following two ways: 1. Via cloud drive: By uploading to a cloud drive (Baidu Netdisk, Aliyun Drive, etc.) and sharing it as a link, the recipient needs to save it to their own cloud drive or download it directly to play, both sender and recipient...
Preface: In recent years, the concept of NAS has been more and more widely accepted by everyone. There are many brands of NAS, and the prices of different models vary greatly. I believe everyone is also quite hesitant when choosing. Therefore, this article of mine is mainly based on my experience as a heavy NAS user (having bought 8 NAS devices...
