一、安装依赖
yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel (3.7以上需要libffi-devel)
二、获取安装包 编译安装
cd Python-3.6.4
./configure --prefix=/usr/local/python3
make && make install
三、创建软连接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
