We all know that in a small company, we not only need code development, but also need some operation and maintenance ability. Because small companies often do not have special operation and maintenance personnel, and everything needs to be done by ourselves.

Below I will learn in the process of normal operation and maintenance of some Ubuntu operation and maintenance experience to share.
