首先nginx容器内部的结构：

进入容器：

docker exec -it b511b6049f57 bash

查看容器的结构目录：其实每一个容器就相当于一个独立的系统。

root@b511b6049f57:/# ls

bin dev home lib64 mnt proc run srv tmp var

boot etc lib media opt root sbin sys usr

nginx的结构目录在容器中：

日志位置：/var/log/nginx/

配置文件位置：/etc/nginx/

项目位置：/usr/share/nginx/html

如果你想在本地去添加location 需要把这些容器中的配置挂载到本地：

配置文件相对来说有点麻烦，一般nginx只需要加载nginx.conf就可以了，在dokcer中，是首先加载nginx.conf，然后在nginx.conf有这么一行include /etc/nginx/conf.d/*.conf;，就是加载conf.d目录下的配置文件。所以对于配置只需要挂载到conf.d,覆盖掉即可。

在本地创建对应的文件夹和主配置文件nginx.conf：


mkdir -p /home/test/nginx/{log,conf,html}
touch nginx.conf

nginx.conf包含子配置文件（最后一行）：


user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid    /var/run/nginx.pid;
events {
  worker_connections 1024;
}
http {
  include    /etc/nginx/mime.types;
  default_type application/octet-stream;
  log_format main  '"$remote_addr" "$http_host" "[$time_local]" "$request" "$status" "$body_bytes_sent" '
          '"$bytes_sent" "$gzip_ratio" "$http_referer" "$http_user_agent" "$http_x_forwarded_for" '
          '"$upstream_addr" "$upstream_response_time" "$request_time" "$request_body" "$http_authorization" ';
  access_log /var/log/nginx/access.log main;
  sendfile    on;
  #tcp_nopush   on;
  keepalive_timeout 65;
  #gzip on;
  include /etc/nginx/conf.d/*.conf;
}

在 conf下创建一个默认的default.conf:


server {
  listen    80;
  server_name localhost;
  #charset koi8-r;
  access_log /var/log/nginx/log/host.access.log main;
  location / {
    #root  /data/nginx/html;
    root  /usr/share/nginx/html;
    index index.html index.htm;
    #autoindex on;
  #try_files $uri /index/index/page.html;
    #try_files $uri /index/map/page.html;
  }
  #error_page 404       /404.html;
  # redirect server error pages to the static page /50x.html
  #
  error_page  500 502 503 504 /50x.html;
  location = /50x.html {
    root  /usr/share/nginx/html;
  }
  location ~ /images {
    default_type              application/json;
    return 200 '{"code": "A000000", "message": "ok", "timestamp": "20180307184426", "data": {"isvip": "1", "monthProList": []}}';
  }
  # proxy the PHP scripts to Apache listening on 127.0.0.1:80
  #
  #location ~ \.php$ {
  #  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;
  #}
}
