Recently I used Raspberry Pi to create a Git private server for all my Git repositories. I spent some time to make everything work correctly, but now it can run.
Install Git
First, install Git on Raspberry Pi.Sudo apt-get install wget git-core
This will install the Git server and necessary client software.

I am using the SSH logon interface because I do not know the default password of the bananapi account, I couldn't find it on the official website, so I had to enter the sudo passwd bananapi command on the keyboard to change the password. Fortunately, I could change the password, and then I could use SSH [email pr

Sometimes it is not convenient to directly operate Raspberry Pi. You may want to use other computers to remotely control Raspberry Pi.
VNC is a graphical interface shared by the system. It allows you to remotely control the desktop interfaces of another computer. It sends keyboard and mouse events from the computer and

The initial step is to format the hard disk on the desktop. This is for convenience. If something goes wrong, we can remove the hard disk from the NAS and read the data on a PC.
It can be formatted on Raspberry Pi, but it will take several hours to format it much faster from the desktop. Do it now.
