In my previous article, I talked about how to build a high-availability system: Two Raspberry Pi deploy the GlusterFS cluster file system, and it becomes a fault-tolerant file server. In this article, we will build another Fault-Tolerant Service Based on this high-availability system: Build a simple Web server cluster. Maybe you have not read my previous article, so here I will briefly review the previous

the selection of external USB devices. One major improvement of Raspberry Pi 2 is that it supports up to 1.2A USB power output when using 2A power input. However, even so, multiple USB mobile hard disks cannot work simultaneously

This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun. Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good. Okay, let's start OpenCV and Python installation.Step
