Suppose an external user wants to access the application corresponding to app1 in the home data center through the link https://app1.example.com, what is the specific access process? You can look at the following flowchart (assuming the home broadband has a public IPv4 address and has I...
In the previous article, we introduced which method should be used to deploy reverse proxies for home broadband under different circumstances. In the next article, we will introduce the working principles and key configuration points of reverse proxies. For a reverse proxy to work properly, two problems need to be solved: the binding of applications and domain names, and the passing of parameters...
When the home data center has completed the deployment of hardware, software, and applications, it is necessary to publish the applications externally. Unlike traditional home broadband which has few applications, publishing applications in a home data center involves many applications, which is far from being as simple as mapping a few ports on a router (provided there is a public IP address)...
Preface: As our internal applications become more numerous and complex, a problem that must be solved is how to monitor the running health of all applications in real-time and receive alarms at the first opportunity when an application encounters problems. To solve this problem, we need to build our own real-time application health monitoring...
When we discussed the choice of software environment for the home data center earlier, we mentioned LNMP (LAMP). Although we will mainly use Docker when deploying home data center applications later, LNMP (LAMP) is still the choice for many production environments. Manually...
Preface: After the home data center is set up, how to manage and operate numerous devices and applications becomes a challenge. Overall, in terms of specific management methods, it is divided into CLI (such as SSH, because SSH is the mainstream CLI management method, so SSH will be used instead of CLI later) and W...
In the previous article, we discussed the hardware choices for building a home data center. In this article, we will mainly discuss the choice of software environment. Deployment method choice: Currently, we have two mainstream methods for deploying applications: LNMP (LAMP) or Docker. 1. Using LNMP (L...
The first step in building a conventional new data center is definitely to choose the building method: on the cloud or self-built? For us, there is no need to hesitate, it is self-built; the second step, strong and weak electricity and wiring, also doesn't need to be worried about. After all, it's a home data center, everything is already built, just use what is available (envious of the rich people who can buy new houses and plan from scratch...
Unprivileged LXC: What is an unprivileged Linux container (LXC)? Unprivileged containers are considered safer and more secure than privileged containers. When an unprivileged container runs, the container's root UID is mapped to a non-root UID on the host system. This makes it so that even if an attacker breaches the container, ...
Preface: Actually, writing an article specifically to talk about multi-dialing doesn't seem to make much sense. The main prerequisite for this is that the home broadband supports multi-dialing, which is purely a stroke of luck: it depends on fate. It just so happens that my home data center has utilized multi-dialing to the extreme, and considering that there are still quite a few netizens whose home broadband supports multi-dialing, ...
