Nginx + Gunicorn + Django 部署web网站

1、安装Django
pip isntall django==1.9.5
2、安装Nginx
yum -y install nginx
3、 配置成开机启动，并手动启动nginx服务：
chkconfig nginx on
service nginx start

4、修改etc/nginx/nginx.conf
user root;
5、然后安装gunicorn:
pip install gunicorn
6、在blog_project下新建gunicorn的配置文件gunicorn.conf.py
workers是工作线程数，一般设置成：服务器CPU个数 + 1
import multiprocessing

bind = "127.0.0.1:8080"
workers = 2
errorlog = '/home/shawn/blog_project/gunicorn.error.log'

accesslog = './gunicorn.access.log'

loglevel = 'debug'

proc_name = 'gunicorn_blog_project'

7、配置文件/etc/nginx.conf

For more information on configuration, see:

 }

 location ~ ^/(media|static)/  {
     root    /home/wuwg/huashanjxhfc;
     expires 30d;
 }


 # this prevents hidden files (beginning with a period) from being served
  location ~ /\. { 
    access_log off; log_not_found off; deny all;
 }

}

}
8、设置项目目录settings.py
INSTALLED_APPS = [
‘app’
‘gunicorn’
]
9、可以运行一下gunicorn:
sudo nohup /usr/local/bin/gunicorn blog_project.wsgi:application -c /home/shawn/blog_project/gunicorn.conf.py&

同时，必须把nginx.conf里server_name后面的内容(localhost)加入到 settings.py里的ALLOWED_HOSTS
ALLOWED_HOSTS = ['localhost','example.com']

如果要外部访问，则打开80端口：

sudo /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sudo service iptatbles save

service nginx restart
