centos7下采用Nginx+uwsgi来部署django

Posted 2020-09-28 苏陌宁

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

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

2、测试

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

1 uwsgi --http :80 --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

1 django-admin startproject myself
2 uwsgi --http :80 --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

 1 #uwsgi.ini file
 2 [uwsgi]
 3 
 4 # Django-related settings
 5 # the base directory (full path)
 6 chdir           = /home/myself
 7 # Django‘s wsgi file
 8 module          = myself.wsgi:application
 9 # the virtualenv (full path)
10 #home            = /path/to/virtualenv
11  
12 # process-related settings
13 # master
14 master          = true
15 # maximum number of worker processes
16 processes       = 3
17 # the socket (use the full path to be safe)
18 #socket          = /home/myself/myself.sock
19 socket = 127.0.0.1:8001
20 # ... with appropriate permissions - may be needed
21 chmod-socket    = 666
22 chown-socket = nginx:nginx
23 # clear environment on exit
24 vacuum          = true
25 enable-threads = true

5、修改nginx配置文件

1 vim /etc/nginx/nginx/conf

  1 # For more information on configuration, see:
  2 #   * Official English Documentation: http://nginx.org/en/docs/
  3 #   * Official Russian Documentation: http://nginx.org/ru/docs/
  4 
  5 user nginx;
  6 worker_processes auto;
  7 error_log /var/log/nginx/error.log;
  8 pid /run/nginx.pid;
  9 
 10 # Load dynamic modules. See /usr/share/nginx/README.dynamic.
 11 include /usr/share/nginx/modules/*.conf;
 12 
 13 events {
 14     worker_connections 1024;
 15 }
 16 
 17 http {
 18     log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
 19                       ‘$status $body_bytes_sent "$http_referer" ‘
 20                       ‘"$http_user_agent" "$http_x_forwarded_for"‘;
 21 
 22     access_log  /var/log/nginx/access.log  main;
 23 
 24     sendfile            on;
 25     tcp_nopush          on;
 26     tcp_nodelay         on;
 27     keepalive_timeout   65;
 28     types_hash_max_size 2048;
 29 
 30     include             /etc/nginx/mime.types;
 31     default_type        application/octet-stream;
 32 
 33     # Load modular configuration files from the /etc/nginx/conf.d directory.
 34     # See http://nginx.org/en/docs/ngx_core_module.html#include
 35     # for more information.
 36     include /etc/nginx/conf.d/*.conf;
 37 
 38     upstream django {
 39     #server unix:/home/myself/myself.sock; # for a file socket
 40     server 127.0.0.1:8001; # for a web port socket (we‘ll use this first)   ---socket
 41     }
 42 
 43     server {
 44         listen       80 default_server;
 45         listen       [::]:80 default_server;
 46         server_name  _;
 47         root         /usr/share/nginx/html;
 48 
 49         # Load configuration files for the default server block.
 50         include /etc/nginx/default.d/*.conf;
 51 
 52         location /static/ {
 53             root /home/myself;                                  ----project地址
 54         }
 55         
 56         location / {
 57             include uwsgi_params;
 58             uwsgi_pass django;                                  ----上面修改socket的位置
 59         }
 60 
 61         error_page 404 /404.html;
 62             location = /40x.html {
 63         }
 64 
 65         error_page 500 502 503 504 /50x.html;
 66             location = /50x.html {
 67         }
 68     }
 69 
 70 # Settings for a TLS enabled server.
 71 #
 72 #    server {
 73 #        listen       443 ssl http2 default_server;
 74 #        listen       [::]:443 ssl http2 default_server;
 75 #        server_name  _;
 76 #        root         /usr/share/nginx/html;
 77 #
 78 #        ssl_certificate "/etc/pki/nginx/server.crt";
 79 #        ssl_certificate_key "/etc/pki/nginx/private/server.key";
 80 #        ssl_session_cache shared:SSL:1m;
 81 #        ssl_session_timeout  10m;
 82 #        ssl_ciphers HIGH:!aNULL:!MD5;
 83 #        ssl_prefer_server_ciphers on;
 84 #
 85 #        # Load configuration files for the default server block.
 86 #        include /etc/nginx/default.d/*.conf;
 87 #
 88 #        location / {
 89 #        }
 90 #
 91 #        error_page 404 /404.html;
 92 #            location = /40x.html {
 93 #        }
 94 #
 95 #        error_page 500 502 503 504 /50x.html;
 96 #            location = /50x.html {
 97 #        }
 98 #    }
 99 
100 }

6、采用Systemd管理uwsgi

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

 1 vim /etc/systemd/system/uwsgi.service
 2 
 3 
 4 [Unit]
 5 Description=uWSGI Emperor
 6 After=syslog.target
 7 
 8 [Service]
 9 ExecStart=/root/uwsgi/uwsgi --emperor /etc/uwsgi/ini
10 Restart=always
11 KillSignal=SIGQUIT
12 Type=notify
13 StandardError=syslog
14 NotifyAccess=all
15 
16 [Install]
17 WantedBy=multi-user.target
