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 :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

django-admin startproject myself
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

#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       = 3
# the socket (use the full path to be safe)
#socket          = /home/myself/myself.sock
socket = 127.0.0.1:8001
# ... with appropriate permissions - may be needed
chmod-socket    = 666
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
