centos8.0.1 升级python3.6到python3.11.0

特别注意： yum的镜像要切到阿里云，如果yum install/update一直调用/etc/yum.repos.d/docker-ce.repo，可以先改名， 再改回来。如下信息：

Trying other mirror.

1、查看当前的python是否安装 whereis python

2、安装依赖：yum groupinstall "Development tools" -y

　　　　　　  yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel -y

3、下载11到任意目录: wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz

ls

7、ln -s /usr/local/bin/python3.11 /usr/local/bin/python3

ln -s /usr/local/bin/pip3.11 /usr/local/bin/pip3
