开发依赖包需要依赖于python3.11环境，但是目前python环境为3.6，于是需要修改python环境为3.11版本
Python 3.11 在 CentOS 7 中没有。我们将从源代码安装它
安装依赖包
yum -y update
systemctl reboot
yum -y install epel-release
yum install wget make cmake gcc bzip2-devel libffi-devel zlib-devel
#使用以下命令从包组安装所有开发工具
yum -y groupinstall "Development Tools"
#查看gcc版本
[root@master1 ~]#gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)
