centos7 yum安装python3.6

sudo yum -y update

sudo yum -y install epel-release

sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm

sudo yum -y install python36

sudo yum -y install python36-pip

查看版本：

python3.6 -V
pip3.6 -V

创建软连接：

ln -s /usr/bin/python3.6 /usr/bin/python3

python3 -V

如果在使用过程中程序报错找不到Python.h，那就把python36卸载了装python36-devel吧
