普通的安装与配置可参考这篇文章：Docker nginx安装与配置挂载
docker安装nginx并配置通过https访问

根据自己的配置实践，强调一点：
启动时，要正确挂载配置中所指向的目录，否则无法找到相关的文件会造成启动的失败，特意mark一下，以供以后参考

下面的配置即为我为了实现小程序mqtt通信而配置的mqtt服务代理内容：

server{
    listen   80;
    listen  443 ssl;
    server_name  ***.******.com;

    ssl_certificate /ssl/cert.pem;
    ssl_certificate_key /ssl/key.pem;
    ssl_session_timeout 5m;
    ssl_session_cache shared:SSL:1m;

    ssl_protocols SSLv2 SSLv3 TLSv1.2; #按照这个协议配置
    ssl_ciphers HIGH:!aNULL:!MD5:!RC4:!DHE;#按照这个套件配置
    ssl_prefer_server_ciphers on;
    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index 2.html;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }


    location = /mqtt {
           proxy_pass https://***.******.com:8084/mqtt;
           proxy_read_timeout 60s;
           proxy_set_header Host $host;
           proxy_set_header X-Real_IP $remote_addr;
           proxy_set_header X-Forwarded-for $remote_addr;
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection 'Upgrade';
        }

}
