centos7.2下安装独立环境的python3.5.2

1.安装centos下python3.5.2的依赖包

yum groupinstall "Development tools"

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2.下载安装python3.5.2

wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz

tar -zxvf Python-3.5.2.tgz

cd Python-3.5.2

./configure prefix=/usr/local/python3.5
进入/usr/local/python3.5/bin
./pip3 install virtualenv
./virtuanenv /home/venv

至此，我们得到了一个独立的py3环境。
