22.项目部署-nginx

什么是nginx

nginx是轻量级的高性能web服务器，提供了注入HTTP代理和反向代理、负载均衡等功能

路由过程

客户端请求nginx，再由nginx将请求转发uwsgi运行的django

安装

tar -zxvf nginx-1.13.7.tar.gz 
cd nginx-1.13.7/
[root@zaishu nginx-1.13.7]# ./configure 
.....
  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx modules path: "/usr/local/nginx/modules"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

make
install

配置

[root@zaishu www]#vi /usr/local/nginx/conf/nginx.conf

    server {
        listen 8996; #暴露给外部访问的端口
        server_name localhost;
        charset utf-8;
        location / {
                include uwsgi_params;
                uwsgi_pass 0.0.0.0:8000; #外部访问8996就转发到内部8997
        }
     }

nginx -t 检查配置文件语法

启动模式变更为uwsig 协议

[root@zaishu www]# cat uwsgi.ini 
[uwsgi]
scoket=0.0.0.0:8000
chdir=/root/www
wsgi-file=www/wsgi.py
process=4
threads=2
pidfile=uwsgi.pid
daemonize=uwsgi.log
master=True

[root@zaishu www]# uwsgi --ini uwsgi.ini

[uWSGI] getting INI configuration from uwsgi.ini

[root@zaishu www]# cd /usr/local/nginx

[root@zaishu nginx]# cd sbin/

[root@zaishu sbin]# ./nginx

访问80

用uwsgi 启动django之后，它就不管静态文件了。此时可以用nginx来加载静态文件。之前在将静态文件的时候，是让告诉那个runserver的。

再次访问，这些静态文件nginx 来处理了
