anythingLLM结合searXNG实现联网搜索

1、docker-compose 部署searXNG

GitHub - searxng/searxng-docker: The docker-compose files for setting up a SearXNG instance with docker.

cd /usr/local
git clone https://github.com/searxng/searxng-docker.git
cd searxng-docker

2、修改 .env文件

# By default listen on https://localhost
# To change this:
# * uncomment SEARXNG_HOSTNAME, and replace <host> by the SearXNG hostname
# * uncomment LETSENCRYPT_EMAIL, and replace <email> by your email (require to create a Let's Encrypt certificate)

SEARXNG_HOSTNAME=172.16.50.25
LETSENCRYPT_EMAIL=381599113@qq.com

# Optional:
# If you run a very small or a very large instance, you might want to change the amount of used uwsgi workers and threads per worker
# More workers (= processes) means that more search requests can be handled at the same time, but it also causes more resource usage

# SEARXNG_UWSGI_WORKERS=4
# SEARXNG_UWSGI_THREADS=4

3、执行下面命令，生成  secret key 

sed -i "s|ultrasecretkey|$(openssl rand -hex 32)|g" searxng/settings.yml

4、修改 Caddyfile，防止 caddy 默认配置的 80端口冲突

{
	admin off
    http_port 8880
	log {
		output stderr
		format filter {
			# Preserves first 8 bits from IPv4 and 32 bits from IPv6
			request>remote_ip ip_mask 8 32
			request>client_ip ip_mask 8 32

			# Remove identificable information
			request>remote_port delete
			request>headers delete
			request>uri query {
				delete url
				delete h
				delete q
			}
		}
	}
}

5、docker-compose配置文件

version: "3.7"

services:
  caddy:
    container_name: caddy
    image: docker.io/library/caddy:2-alpine
    network_mode: host
    restart: always
    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: "10m"
        max-file: "1"

  redis:
    container_name: redis
    image: docker.io/valkey/valkey:8-alpine
    command: valkey-server --save 30 1 --loglevel warning
    restart: always
    networks:
      - searxng
    volumes:

    cap_drop:

    cap_add:

      - 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: always
    networks:
      - searxng
    ports:
      - "8080:8080"
    volumes:
      - ./searxng:/etc/searxng:rw
    environment:
      - SEARXNG_BASE_URL=https://${SEARXNG_HOSTNAME:-localhost}/
      - UWSGI_WORKERS=${SEARXNG_UWSGI_WORKERS:-4}

如果不需要反向代理，其中的caddy配置可以删除，

还有SEARXNG_BASE_URL 是 SearXNG 服务的基础 URL 配置参数，主要用于定义实例对外访问的协议、域名和端口信息‌。该参数直接影响搜索结果链接生成、静态资源加载路径以及反向代理的配置适配性，是部署时确保内外网访问一致性的关键配置项。

本地调试场景‌
若仅本地访问且未启用 HTTPS，可设置为：

  - SEARXNG_BASE_URL=http://172.16.50.25:8080/

On the first run, you must remove cap_drop: - ALL from the docker-compose.yaml file for the searxng service to successfully create /etc/searxng/uwsgi.ini. This is necessary because the cap_drop: - ALL directive removes all capabilities, including those required for the creation of the uwsgi.ini file. After the first run, you should re-add cap_drop: - ALL to the docker-compose.yaml file for security reasons.

6、配置  settings.yml

项目默认的搜索返回的格式为 html 格式，在使用网络爬虫或其它形式的分析器调用 API 时，希望返回 json 格式，这时就需要修改返回格式。

添加以下内容

search:
  formats:
  - html
  - csv
  - json
  - rss

整体内容如下

# see https://docs.searxng.org/admin/settings/settings.html#settings-use-default-settings
use_default_settings: true
server:
  # base_url is defined in the SEARXNG_BASE_URL environment variable, see .env and docker-compose.yml
  secret_key: "58e0507b6a5428c2f87e26fc83509028f53a12daa1800448dcd7c47c19c7bb6e"  # change this!
  limiter: false  # can be disabled for a private instance
  image_proxy: true
ui:
  static_use_hash: true
redis:
  url: redis://redis:6379/0
  
search:
  formats:
  - html
  - csv
  - json
  - rss
