ubuntu配置django环境

1、申请云主机，部署ubuntu主机，开放22端口

2、系统Ubuntu16.04，系统自带2个版本的python，一个是python2.7，一个是python3.5

安装pip工具

sudo apt-get install python3-pip

安装本地虚拟环境管理工具

sudo apt-get install python3-virtualenv

python2 --version #查看python2安装版本

python3 --version #查看python3安装版本

echo alias python=python3 >> ~/.bashrc

source ~/.bashrc

python --version  变成python3了

ubuntu查看 python安装路径

s@s-pc:~/mypython$ which python
/usr/bin/python

pip install virtualenv
root@ecs-a20c:/tmp/my_project_output# cd venv
root@ecs-a20c:/tmp/my_project_output/venv# source ./bin/activate

python3 manage.py runserver
#virtualenv 虚拟环境名称
#virtualenv --python=/usr/bin/python3.6 虚拟环境名称
pip list
#source activate
#deactivate
virtualenv --python=/usr/bin/python3.6 虚拟环境名称
virtualenv -p /usr/bin/python3 venv

apt install python-pip
pip install --upgrade pip
pip3 install django
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple django
