First install rsync
# Server ConfigurationThe server uses 'xinetd' to act as the 'rsync' daemon. If not, install> Xinetd listens to a specified port, fork the service program corresponding to the configured port, and then continues to listen.
#1. Configure the xinetd configuration file for rsync:

Like XML, it's lighter, faster, and simpler than XML. If you need to serialize and protocol your data, it is recommended that you use the nano Protobufs. For more details, please refer to the "

After creating a USB flash drive, restart the machine and start it from the USB flash drive. Go to the installation page. You can select a graph or text. Personally, the text is faster.
