使用Docker搭建SearXNG搜索引擎

1、安装Docker

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

2、安装SearXNG

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

创建目录：

mkdir searxngcd 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  by the SearXNG hostname# * uncomment LETSENCRYPT_EMAIL, and replace  by your email (require to create a Let\'s Encrypt certificate)# SEARXNG_HOSTNAME=# LETSENCRYPT_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=/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\' Caddyfilesed -i \'s/tls {$SEARXNG_TLS}/#tls {$SEARXNG_TLS}/g\' Caddyfilesed -i \'s/Content-Security-Policy/#Content-Security-Policy/g\' Caddyfile

查看searxng/settings.yml文件：

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.ymlsed -i \"s/redis:6379/searxng-redis:6379/g\" searxng/settings.yml

备份docker-compose.yaml文件：

cp docker-compose.yaml docker-compose.yaml-bak

修改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
