centos7下采用Nginx+uwsgi来部署django

之前写过采用Apache和mod_wsgi部署django，因为项目需要，并且想比较一下Nginx和Apache的性能，尝试采用Nginx+uwsgi的模式来部署django。

1、安装uwsgi以及Nginx

 pip install uwsgi                          --目前的版本为2.0.15
 yum install epel-release
 yum install nginx*                         --目前的版本为1.10.2

2、测试

 # test.py
 def application(env, start_response):
     start_response('200 OK', [('Content-Type','text/html')])
     return "Hello World"

 uwsgi --http : --wsgi-file test.py

采用浏览器访问主机或者采用postman模拟get操作，如果出现"Hello World"即测试成功

3、测试django工程

 django-admin startproject myself
 uwsgi --http : --chdir /home/myself --module myself.wsgi

并在django工程的settings里边添加主机的ip地址，采用浏览器访问主机或者采用postman模拟get操作，如果出现django的欢迎页面，“It works!”即测试成功

4、写uwsgi.ini配置文件

 #uwsgi.ini file
 [uwsgi]

 # Django-related settings
 # the base directory (full path)
 chdir           = /home/myself
 # Django's wsgi file
 module          = myself.wsgi:application
 # the virtualenv (full path)
 #home            = /path/to/virtualenv

 # process-related settings
 # master
 master          = true
 # maximum number of worker processes
 processes       =
 # the socket (use the full path to be safe)
 #socket          = /home/myself/myself.sock
 socket = 127.0.0.1:
 # ... with appropriate permissions - may be needed
 chmod-socket    =
 chown-socket = nginx:nginx
 # clear environment on exit
 vacuum          = true
 enable-threads = true

5、修改nginx配置文件

 vim /etc/nginx/nginx/conf

 # For more information on configuration, see:
 #   * Official English Documentation: http://nginx.org/en/docs/
 #   * Official Russian Documentation: http://nginx.org/ru/docs/

 user nginx;
 worker_processes auto;
 error_log /var/log/nginx/error.log;
 pid /run/nginx.pid;

 # Load dynamic modules. See /usr/share/nginx/README.dynamic.
 include /usr/share/nginx/modules/*.conf;

 events {
     worker_connections 1024;
 }

 http {
     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for"';

     access_log  /var/log/nginx/access.log  main;

     sendfile            on;
     tcp_nopush          on;
     tcp_nodelay         on;
     keepalive_timeout   65;
     types_hash_max_size 2048;

     include             /etc/nginx/mime.types;
     default_type        application/octet-stream;

     # Load modular configuration files from the /etc/nginx/conf.d directory.
     # See http://nginx.org/en/docs/ngx_core_module.html#include
     # for more information.
     include /etc/nginx/conf.d/*.conf;

     upstream django {
     #server unix:/home/myself/myself.sock; # for a file socket
     server 127.0.0.1:8001; # for a web port socket (we'll use this first)   ---socket
     }

     server {
         listen       80 default_server;
         listen       [::]:80 default_server;
         server_name  _;
         root         /usr/share/nginx/html;

         # Load configuration files for the default server block.
         include /etc/nginx/default.d/*.conf;

         location /static/ {
             root /home/myself;                                  ----project地址
         }

         location / {
             include uwsgi_params;
             uwsgi_pass django;                                  ----上面修改socket的位置
         }

         error_page 404 /404.html;
             location = /40x.html {
         }

         error_page 500 502 503 504 /50x.html;
             location = /50x.html {
         }
     }

 # Settings for a TLS enabled server.
 #
 #    server {
 #        listen       443 ssl http2 default_server;
 #        listen       [::]:443 ssl http2 default_server;
 #        server_name  _;
 #        root         /usr/share/nginx/html;
 #
 #        ssl_certificate "/etc/pki/nginx/server.crt";
 #        ssl_certificate_key "/etc/pki/nginx/private/server.key";
 #        ssl_session_cache shared:SSL:1m;
 #        ssl_session_timeout  10m;
 #        ssl_ciphers HIGH:!aNULL:!MD5;
 #        ssl_prefer_server_ciphers on;
 #
 #        # Load configuration files for the default server block.
 #        include /etc/nginx/default.d/*.conf;
 #
 #        location / {
 #        }
 #
 #        error_page 404 /404.html;
 #            location = /40x.html {
 #        }
 #
 #        error_page 500 502 503 504 /50x.html;
 #            location = /50x.html {
 #        }
 #    }

 }

6、采用Systemd管理uwsgi

 mkdir -p /etc/uwsgi/ini
 mv /home/myself/uwsgi.ini /etc/uwsgi/ini/

 vim /etc/systemd/system/uwsgi.service

 [Unit]
 Description=uWSGI Emperor
 After=syslog.target

 [Service]
 ExecStart=/root/uwsgi/uwsgi --emperor /etc/uwsgi/ini
 Restart=always
 KillSignal=SIGQUIT
 Type=notify
 StandardError=syslog
 NotifyAccess=all

 [Install]
 WantedBy=multi-user.target
