Write in the front: In the following steps, you need to enter commands in the terminal. Friends who view blogs on the computer side can copy and paste them directly to the terminal. Friends who view blogs on the mobile phone side please note that the spaces in the commands are required, otherwise there will be errors.

1. Set initial password for root
