Operating instructions

1) The line in the document that starts with "$" followed by the Linux command.
2) It is recommended that all Linux commands in the document be manually input to the Linux host for execution (copy and paste directly to the Linux host for execution, and execution may fail).
3) The Linux execution command in the document. If the next character after the space is "-" (such as: sudo apt-get -y install and the like), please manually enter the Linux host to execute (copy and paste directly to Linux On the host, it usually fails).
4) Please enter the Linux commands that have not been written on all lines in the document manually and execute them on the Linux host (because the copy and paste commands cannot contain special characters like "newline characters").
5) When entering and executing Linux commands according to the document, observe whether the execution result of the command is consistent with that in the picture of the document to confirm whether the command is entered incorrectly and whether the execution fails.
6) Please compile the first pass strictly according to the documentation, otherwise inexplicable errors may occur.
