1. Installation instructions

The built-in Python of Centos8 is version 3.6.8. Here are the installation steps based on the built-in Python3.6.8. As the installation of multiple versions of Python will cause the underlying libraries of the system to download source code and recompile, it is not recommended to install the Chinese version of Redash in multi-version Python environments.
