使用Docker实现客户化本地部署集成搜索引擎SearXNG

使用前提：已安装Docker软件，用于Dify等第三方调用，需增加son输出格式。

安装Searxng

1、到Searxng公司开发的Docker在GitHub的网站（https://github.com/searxng/searxng-docker）下载zip包，并解压到指定文件夹。

2、打开该文件夹，修改docker-compose.yaml，重点修改Caddy和端口两处，不使用反向代理注释或删除caddy相关内容，包括 #volumes中caddy相关的内容，端口按需修改。

完整 docker-compose.yaml 代码：

version: "3.7"
 
services: 
  # 不使用反向代理注释掉或删除caddy相关内容，包括 下面volumes中caddy:相关的内容
  #caddy: 
  #  container_name: caddy
  #  image: docker.io/library/caddy:2-alpine
  #  network_mode: host
  #  restart: unless-stopped
  #  volumes:
  #    - ./Caddyfile:/etc/caddy/Caddyfile:ro
  #    - caddy-data:/data:rw
  #    - caddy-config:/config:rw
  #  environment:
  #    - SEARXNG_HOSTNAME=${SEARXNG_HOSTNAME:-http://localhost}
  #    - SEARXNG_TLS=${LETSENCRYPT_EMAIL:-internal}
  #  cap_drop:
  #    - ALL
  #  cap_add:
  #    - NET_BIND_SERVICE
  #  logging:
  #   driver: "json-file"
  #    options:
  #     max-size: "1m"
  #     max-file: "1"
 
  redis:
    container_name: redis
    image: docker.io/valkey/valkey:8-alpine
    command: valkey-server --save 30 1 --loglevel warning
    restart: unless-stopped
    networks:
      - searxng
    volumes:
      - valkey-data2:/data
    cap_drop:
      - ALL
    cap_add:
      - SETGID
      - SETUID
      - DAC_OVERRIDE
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "1"
 
  searxng:
    container_name: searxng
    image: docker.io/searxng/searxng:latest
    restart: unless-stopped
    networks:
      - searxng
    ports:
      - "8081:8080" # 去掉127.0.0.1,还有冒号前端口为对外提供服务口，如不冲突可以不该
    volumes:
      - ./searxng:/etc/searxng:rw
    environment:
      - SEARXNG_BASE_URL=https://${SEARXNG_HOSTNAME:-localhost}/
      - UWSGI_WORKERS=${SEARXNG_UWSGI_WORKERS:-4}
      - UWSGI_THREADS=${SEARXNG_UWSGI_THREADS:-4}
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - SETGID
      - SETUID
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "1"
 
networks:
  searxng:
 
volumes:
#  caddy-data:
#  caddy-config:
  valkey-data2:

3、修改searxng子文件夹下 settings.yml 文件：general：选项，修改调试模式为: false，客户化网页标题名称 instance_name: “MySou” #网页标题名称；server：修改 secret_key：为自己的密码，将图片代理设置为：ture；search选项：将自动完成输入改成百度（baidu），默认搜索语言 default_lang设置为中文 “zh-CN”，格式增加json，方便Dify等第三方软件调用；ui选项：将自动完成输入改成百度（baidu），将UI页面默认改为中文（”zh-Hans-CN” ），将页面风格 simple_style：选为自己的，有亮light、暗 dark、自动auto可选。

接着请搜索引擎选择方面，将百度、360搜索设置为启用，并按需禁用无效的搜索引擎

最后按需设置搜索分类，如图只保留了综合、图片、视频、新闻四类。

特别提醒，文件对其格式必须严格，类别标签必须顶头靠左，避免出现内部错误。详细设置建议查看 https://docs.searxng.org/admin/settings/settings.html 文档

4、设置完成后在 saerxng-docker 文件夹点击在终端打开，在终端窗口下输入命令：docker-compose up -d，等待拉取镜像，直至拉取完毕并启动镜像。
