1、安装Docker

# 安装Docker
https://docs.docker.com/get-docker/# 安装Docker Compose
https://docs.docker.com/compose/install/# CentOS安装Docker
https://mp.weixin.qq.com/s/nHNPbCmdQs3E5x1QBP-ueA

2、安装SearXNG

详见：
https://docs.searxng.org/admin/installation-docker.html
https://github.com/searxng/searxng-docker

创建目录：

mkdir searxng
cd searxng

下载：

wget https://github.com/searxng/searxng-docker/archive/refs/heads/master.zip

解压：

# 安装zip、unzip
# yum install -y zip unzip# 解压
unzip master.zip

切换目录：

cd searxng-docker-master

查看.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=<host>
# LETSENCRYPT_EMAIL=<email>

备份.env文件：

cp .env .env-bak

修改.env文件：

# 指定域名或ip，
# 假设当前ip为192.168.186.128，端口3000，供外网访问
sed -i 's/# SEARXNG_HOSTNAME=<host>/SEARXNG_HOSTNAME=http:\/\/192.168.186.128:3000/g' .env

查看Caddyfile文件：

备份Caddyfile文件：

cp Caddyfile Caddyfile-bak

修改Caddyfile文件：

sed -i 's/admin off/#admin off\n        http_port 3000\n        auto_https off/g' Caddyfile
sed -i 's/tls {$SEARXNG_TLS}/#tls {$SEARXNG_TLS}/g' Caddyfile
sed -i 's/Content-Security-Policy/#Content-Security-Policy/g' Caddyfile

查看searxng/settings.yml文件：

# 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.ymlsecret_key: "ultrasecretkey"  # change this!limiter: false  # enable this when running the instance for a public usage on the internetimage_proxy: true
redis:url: redis://redis:6379/0

备份searxng/settings.yml文件：

cp searxng/settings.yml searxng/settings.yml-bak

修改searxng/settings.yml文件：

sed -i "s/ultrasecretkey/$(openssl rand -hex 32)/g" searxng/settings.yml
sed -i "s/redis:6379/searxng-redis:6379/g" searxng/settings.yml

查看docker-compose.yaml文件：

说明：使用caddy做反向代理
假设ip为192.168.186.128，caddy默认端口80，searxng默认端口8080
在浏览器访问192.168.186.128:80如果将caddy端口改成3000，那么在浏览器访问192.168.186.128:3000

创建并启动容器：

docker-compose up -d

查看容器列表：

docker ps

查看容器日志：

# Caddy容器: 
docker logs -f searxng-caddy# SearXNG容器: 
docker logs -f searxng# Valkey容器: 
docker logs -f searxng-redis

停止并销毁容器：

docker-compose down

删除目录：

rm -rf ./caddy-data ./caddy-config ./valkey-data2 ./searxng-data

3、浏览器访问

假设当前ip为192.168.186.128
浏览器访问：http://192.168.186.128:8080
