centos7下通过nginx+gunicorn部署django应用笔记

1.安装基础环境启动gunicorn

新建虚拟环境imooc并切换到imooc
pip install django==2.0 gunicorn
django-admin startproject imooc
cd imooc

命令行启动
gunicorn imooc.wsgi:application -w 2 -b 127.0.0.1:8000
imooc.wsgi:application imooc是你django工程的名称，后面不用改
-w --workers 意思是要启动的进程数量
-b --bind 绑定的IP地址和端口
-k --worker-class 启动的worker类型（gthread,sync,eventlet,gevent,tornado）,默认是同步阻塞方式启动
访问：127.0.0.1:8000

以配置文件启动：
gunicorn imooc.wsgi:application -k gthread -c ~/projects/imooc/conf/gunicorn.conf.py

# gunicorn.conf.py
import multiprocessing
bind = "127.0.0.1:8888"
workers = 2
errorlog = ' ~/projects/imooc/log/error.log'
accesslog = ' ~/projects/imooc/log/access.log'
#loglevel = 'info'
loglevel = 'error'

2.收集静态文件

# imooc settings.py
ALLOWED_HOSTS = ['127.0.0.1', 'localhost', '10.67.9.113',]
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
DEBUG = False

# urls.py
from imooc.settings import STATIC_ROOT
from django.views.static import serve
from django.conf.urls import url

urlpatterns = [
    path('admin/', admin.site.urls),
    url('^static/(?P<path>.*)/$', serve, {"document_root": STATIC_ROOT}),
]

运行 python manage.py collectstatic

运行gunicorn
gunicorn imooc.wsgi:application -k gthread -c ~/projects/imooc/conf/gunicorn.conf.py

3.安装并启动nginx

1.安装nginx和开放http服务与端口
https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-centos-7
systemctl start nginx 访问设备IP出现欢迎界面
systemctl enable nginx 设置nginx自启动

2.新建gunicorn.nginx.conf
vim ~/projects/imooc/conf/gunicorn.nginx.conf

# gunicorn.nginx.conf
server {
    # the port your site will be served on
    listen      8080;
    # the domain name it will serve for
    server_name      设备IP地址; # 设备IP地址或者绑定的域名
    charset     utf-8;

    location / {
        proxy_pass http://127.0.0.1:8000;#gunicorn绑定的地址
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location /static {
        alias ~/projects/imooc/static; # your Django project's static files - amend as required
    }
}
3.建立软连接
touch /etc/nginx/conf.d/(不存在再创建)
ln -s ~/projects/imooc/conf/gunicorn.nginx.conf /etc/nginx/conf.d/
4.修改/etc/nginx/nginx.conf并启动nginx
http{...}添加如下一行：
include /etc/nginx/conf.d/*.conf;
并修改用户为服务器当前登录用户
sudo /usr/sbin/nginx -t
systemctl restart nginx
