起飞前的准备
# 首先在Ubuntu的当前用户zhang下新建data文件夹，然后在data文件夹下新建你的项目目录
root@zhang-virtual-machine:/home/zhang/data# mkdir my_web_project root@zhang-virtual-machine:/home/zhang/data# ls my_web_project root@zhang-virtual-machine:/home/zhang/data# cd my_web_project/
# virtualenv --no-site-paceages env 创建虚拟环境，--no-site-packages 表示一个干净的目录，不会安装没必要的包 root@zhang-virtual-machine:/home/zhang/data/my_web_project# virtualenv --no-site-packages env Using base prefix '/usr' New python executable in /home/zhang/data/my_web_project/env/bin/python3 Also creating executable in /home/zhang/data/my_web_project/env/bin/python Installing setuptools, pip, wheel...done. root@zhang-virtual-machine:/home/zhang/data/my_web_project# ls env root@zhang-virtual-machine:/home/zhang/data/my_web_project# cd env/ root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# ls bin include lib pip-selfcheck.json
# 激活虚拟环境 root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# source bin/activate
#查看版本，查看到当前的环境下没有太多的包 (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip -V pip 10.0.0 from /home/zhang/data/my_web_project/env/lib/python3.5/site-packages/pip (python 3.5) (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip list Package Version ---------- ------- pip 10.0.0 setuptools 39.0.1 wheel 0.31.0
# 退出虚拟环境 (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# deactivate root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# source bin/activate
# 安装1.10.4版本的Django
(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip install django==1.10.4 Collecting django==1.10.4
# 安装uwsgi
(env) root@zhang-virtual-machine:/home/zhang/data/my_web_project/env# pip install uwsgi Collecting uwsgi
第一步：uwsgi
首先测试uwsgi，并用uwsgi启动服务
def application(env, start_response): start_response('200 OK', [('Content-Type','text/html')]) return [b"Hello uwsgi!"]
刚开始按照网上说的用这个方法启动老是报错 (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# python app.py (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# uwsgi --http :8008 --wsfi-file app.py uwsgi: unrecognized option '--wsfi-file' getopt_long() error 最后发现启动的方式默认是socket的方式 (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# uwsgi --http-socket :8008 --wsgi-file app.py *** Starting uWSGI 2.0.17 (64bit) on [Tue Apr 17 19:05:22 2018] *** compiled with version: 5.4.0 20160609 on 18 April 2018 01:30:18 os: Linux-4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017
第二步：nginx
# 直接在命令行下运行 apt-get install nginx (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# apt-get install nginx Reading package lists... Done Building dependency tree Reading state information... Done
nginx的启动与关闭 (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# service nginx stop (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# ps aux | grep nginx (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# service nginx start (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project# ps aux | grep nginx root 55075 0.0 0.0 124968 1420 ? Ss 19:24 0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on; www-data 55076 0.0 0.1 125332 3072 ? S 19:24 0:00 nginx: worker process www-data 55077 0.0 0.1 125332 3072 ? S 19:24 0:00 nginx: worker process www-data 55078 0.0 0.1 125332 3072 ? S 19:24 0:00 nginx: worker process www-data 55079 0.0 0.1 125332 3072 ? S 19:24 0:00 nginx: worker process root 55082 0.0 0.0 14220 988 pts/20 S+ 19:24 0:00 grep --color=auto nginx (env) root@zhang-virtual-machine:/home/zhang/data/my_web_project#
nginx的配置文件都在
# /etc/nginx/... (env) root@zhang-virtual-machine:/etc/nginx# ls conf.d fastcgi_params koi-win nginx.conf scgi_params sites-enabled uwsgi_params fastcgi.conf koi-utf mime.types proxy_params sites-available snippets win-utf
此时访问浏览器可以看到如下：
第三步：Django+uwsgi+nginx
nginx的配置文件所在路径： /etc/nginx/nginx.conf
uwsgi 所在路径：项目更目录
启动项目： uwsgi --ini demo.ini & #利用配置文件启动，默认不在终端显示 /etc/init.d/nginx start #启动nginx
附加：
supervisor是一个对进程管理的软件，可以帮助我们启动uwsgi并维护（uwsgi进程关闭时，自动将其启动起来）。
安装：apt-get install supervisor
配置 vim /etc/supervisor/supervisor.conf

启动： supervisord /etc/supervisor.conf #这个总是报错，不知道什么原因 或 /etc/init.d/supervisor start #这个比较好用
