Preface
Because I have been very interested in linux, I started an experiment with Raspberry Pi and set up a simple php server to run typecho.
However, the process is extraordinary, and almost every step is stuck. in addition, compared with WordPress, typecho has less data, which makes the process of solving the problem a little difficult.
The first is the Raspberry
