virtualenv

virtualenvIt is a great tool that can help us manage different Python environment.
virtualenvIs a different and may interfere with each other to create multiple virtual environments in the system.

The following steps will create two independent virtual environments, and are installed running django1.11.11, djagno2.0.

# 我们先升级pip
pip3.6 install --upgrade pip

# 指定清华源下载virtualenv
pip3.6 install -i https://pypi.tuna.tsinghua.edu.cn/simple virtualenv

# 下载后，准备一个目录
mkdir all_env

# 进入目录，创建两个独立的运行环境，分别为venv01、venv02
virtualenv --no-site-packages --python=python3.6 venv01
virtualenv --no-site-packages --python=python3.6 venv02

# 创建完成后，打开两个终端，分别先进入venv01、venv02虚拟环境。进入后，终端提示符会有虚拟环境标示
. venv01/bin/activate  # 进入venv01
source venv02/bin/activate  # 进入venv02

# 分别安装django1.11.1、django2.0
pip3.6 install django==1.11.11  # venv01
pip3.6 install django==2.0  # venv02

# 分别创建django项目
django-admin startproject blog01  # venv01
django-admin startproject blog02  # venv02

# 分别修改setting.py配置文件内定义的允许访问的网段，修改后启动俩项目
python3.6 manage.py runserver 0.0.0.0:8001  # venv01
python3.6 manage.py runserver 0.0.0.0:8002  # venv02

# 所有配置就绪
# 在访问前，请确保防火墙允许通行
