Introduction
There are two main reasons for introducing the concepts of users and groups:1. When providing bioinformatics servers (Why use servers for bioinformatics analysis?), some students ask: Is my data stored on the server secure? Will someone be able to view and steal my data? This question can be answered as follows: Linux has a strict user system that ensures the permissions and privacy of each user. Therefore, the data you store on the server cannot be read or written by other users; access to other users’ data will be denied by the system:
2. Another factor is that our brand new 3.0 system has been launched after long-term debugging (3.0 system launched for internal testing, free upgrade + three months of free usage), which means that even if you use a shared server in the future, you will have an independent environment and root privileges, making the experience similar to using a dedicated physical machine. Therefore, we can later guide you through the installation of Rstudio, deployment of shiny, nginx, and other software that requires administrator privileges for installation. Thus, we need to establish the concept of users and groups as a foundation for subsequent tutorials.
