Python route-Jobs: Class Farbic host hypervisor (for reference only)

First, the operation needs

1. Run the program to list host groups or hosts
2. Select the specified host or group
3. Choose to have the host or host group execute commands or transfer files to them (upload/download)
4. Make full use of multi-threaded or multi-process
5. Different host user name password, port can be different

Second, realize the function

1. Create a host
2. Running the program lists the host list
3. Select a designated host or group
4. Choose to have the master or host group execute commands or transfer files
5. Full use of multithreading Note: The new user to use this program 1, the creation of the host-------> to be based on their own now open host to create a host, the host information in the form of files saved;

                      2, connecting the host-------> According to the user-created host, read the DB directory using the host information, return the form of the list, and try to connect, the connection success status is set to 1, the connection is not successful status is set to 0;
                      3, running the host-------> According to the previous step identified can be connected to the host, the Output class connection host list, according to the user's Choice and command input to control the host
                            Put upload file method------> upload the local file under LocalHost, and only the input file name can be
                                                    The path of the file is saved only with the directory and file name "/downloads/aaa", and the program automatically adds the "/username" prefix path
                            Get upload file method------> The path of the files downloaded from the remote host only with the input directory and file name "/DOWNLOADS/AAA", the program will automatically add "/username" prefix path
                                                    Downloaded files are saved by default under localhost
