nginx 对django项目的部署
Django部署方式有很多种，之前写过一篇部署在Apache上的博文：https://www.cnblogs.com/shenh/p/7552722.html 。下文介绍的是通过Nginx来部署。
Nginx是一个高性能的HTTP和反向代理服务，运用非常广泛。Django应用可以通过Nginx+uwsgi的方式进行部署。Nginx放置在服务器的最前端来接收所有web请求，统一管理，首先分离出静态请求，自己做处理。然后，Nginx将非静态请求通过uwsgi转发给Django，由Django处理。
一、安装Nginx
安装Nginx命令
apt-get install Nginx
Nginx的默认端口为80，很容易被其他服务占用，因此需要修改成其他端口。打开文件 vi /etc/nginx/nginx.conf ，如果能找到监听的端口，直接修改 。找不到的也没关系 ，找到如下配置 ，说明是引用了其他目录的文件
...
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
...打开 /etc/nginx/sites-enabled/ ，找到并编辑 default ，将80修改成8088
# Default server configuration
#
server {
listen 8088 default_server;
listen [::]:8088 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don‘t use them in a production server!
#
# include snippets/snakeoil.conf;Nginx启动命令
service nginx start service nginx restart service nginx stop
测试下，访问 http://10.1.35.51:8088/
二、配置uwsgi
1.安装
pip 安装 uwsgi 命令：
pip install uwsgi
2.配置 uwsgi 和 Django 的连接
Django 项目路径位于 /home/project/web/ ，在 Django 项目根目录（manage.py 同级目录）新建文件 uwsgi.ini （也支持 xml 文件格式）。在文件中添加如下内容：
# uwsgi.ini file [uwsgi] # Django-related settings socket = :8000 # the base directory (full path) chdir = /home/project/web # Django s wsgi file module = web.wsgi # process-related settings master = true # maximum number of worker processes processes = 5#maximum number of worker threadsthreads = 5
# try to remove all of the generated file/sockets vacuum = true
3. 配置 uwsgi 和 Nginx 的连接
修改Nginx配置文件：vi /etc/nginx/sites-available/default ，增加一段配置。然后重启Nginx
server {
listen 8099;
server_name 127.0.0.1
charset UTF-8;
access_log /var/log/nginx/web_access.log;
error_log /var/log/nginx/web_error.log;
client_max_body_size 75M;
location / {
include uwsgi_params; # 通过uwsgi转发请求
uwsgi_pass 127.0.0.1:8000; # 和上文配置的socket端口保持一致
uwsgi_read_timeout 15; # 设置请求超时时间
}
location /static { # 访问静态资源
expires 30d;
autoindex on;
add_header Cache-Control private;
alias /var/web/;
}
}4.配置 Django 静态资源
在setting里增加配置，静态资源 路径 和 Nginx 里的访问路径一致
STATIC_ROOT = os.path.join(BASE_DIR,‘/var/web‘)
执行命令
Python manage.py collectstatic
5.最后启动项目
cd /home/project/web uwsgi --ini uwsgi.ini
运行成功：
