linux 安装PYTHON 3

yum -y groupinstall "Development tools"

yum -y install openssl-devel zlib-devel ncurses-devel bzip2-devel readline-devellibtool-

       安装上面这些python内置模块基本上就比较全了，如果后续有其他必要的模块，会继续补充的，接下来可以安装python了，编译过程中会自动包含这些依赖.

下载到一个目录解压

cd Python-3.7.0

继续以下命令

./configure --prefix=/usr/python --enable-shared CFLAGS=-fPIC
make && make install
ln -s /usr/python/bin/python3 /usr/bin/python3
ln -s /usr/python/bin/pip3 /usr/bin/pip3
