**1. Unix域套接字是什么？**  
是进程间通信(IPC)的一种方法  
是可靠的一种IPC通信，是POSIX标准的一个组件  
只能用于同一主机间的通信

**2. 网络套接字 VS Unix域套接字**

**3. Unix套接字的使用**  
**3.1 部署Nginx + uWSGI服务**[【基础要求】][Link 1]  
**3.1.1.创建uWSGI启动文件**

[root@node django_deployment]# cat django-uwsgi-sock.ini
    [uwsgi]
    chdir       = /home/hhx/deployment/django_deployment
    module      = django_deployment.wsgi
    # http-socket = :8000
    socket      = /usr/local/nginx/logs/django.sock
    master      = True
    processes   = 1
    threads     = 4
    vacuum      = True
    
    # backend run uwsgi, set log-size 1G
    daemonize   = %(chdir)/log/uwsgi-sock.log
    log-maxsize = 1073741824
    pidfile     = %(chdir)/pid/uwsgi-sock.pid
    [root@node django_deployment]# uwsgi --ini django-uwsgi-sock.ini

**3.1.2.修改Nginx配置文件**

[root@node django_deployment]# pwd
    /home/hhx/deployment/django_deployment
    [root@node django_deployment]# cd /usr/local/nginx/conf/
    [root@node django_deployment]# cat /usr/local/nginx/conf/nginx.conf | grep -v ^$ | egrep -v '#' 
    user  nobody;
    worker_processes  1;
    events { 
        worker_connections  1024;
    }
    http { 
        include       mime.types;
        include       uwsgi_params;
        default_type  application/octet-stream;
        sendfile        on;
        keepalive_timeout  65;
        upstream uwsgi { 
            server unix:///usr/local/nginx/logs/django.sock;
        }
        server { 
            listen 80;
            server_name .python3.com;
            return 301 https://$host$request_uri;
        }
        server { 
            listen       443 ssl;
            server_name  .python3.com;
            charset utf-8;
            ssl_certificate      cert/cert.pem;
            ssl_certificate_key  cert/cert.key;
            ssl_session_cache    shared:SSL:1m;
            ssl_session_timeout  5m;
            ssl_ciphers  HIGH:!aNULL:!MD5;
            ssl_prefer_server_ciphers  on;
            access_log logs/https-uwsgi.log;
            location / { 
                uwsgi_pass uwsgi;
            }
            location /static { 
                alias static;
            }
        }
    }
    [root@node django_deployment]# nginx -s reload

**3.1.3 测试**  
DEBUG终端

[root@node django_deployment]# tail -f /usr/local/nginx/logs/error.log

终端A

[root@node django_deployment]# tail -f /usr/local/nginx/logs/https-uwsgi.log

终端B

[root@node django_deployment]# tail -f /home/hhx/deployment/django_deployment/log/uwsgi-sock.log

Web访问python3.com
