2.宿主机nginx

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        root   html;
        index  index.html index.htm;
        # deny  xxx.xxx.xxx.xxx;
        # allow  192.168.1.0/24;
    }

    #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   html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
    location /test {
        proxy_pass  http://127.0.0.1:6666/; #最后如果没有反斜杠，那么转发请求是http://127.0.0.1:6666/test, 如果最后有反斜杠，那么转发请求就是http://127.0.0.1:6666/
    }
}

3. docker开启

docker container run \
  -d \
  -p 6666:80 \
  --rm \
  --name mynginx \
  nginx:1.14

4.测试

浏览器中输入http://主机IP/        ------>  访问的是宿主主机的nginx

浏览器中输入http://主机IP/test  ------>  访问的是宿主主机转发给docker中的nginx

5.备注：

需要注意nginx中root(相对路径，路径的拼接)和alias（绝对路径）的区别，同时需要注意配置文件中代理的反斜杠有无的区别
