Static WebHost

Author: Serein-213

Deploy static files to Caddy or Nginx. Auto-detects which server is available.

⚠️ 安全警告 / Security Warning

此 skill 执行的操作需要 elevated privileges（sudo/root），属于高危操作。

权限需求

• 写入系统目录: /var/www/html/（Web 根目录）
• 修改配置文件: /etc/nginx/ 或 /etc/caddy/Caddyfile
• 系统服务管理: systemctl reload nginx/caddy
• 包管理器操作: pacman -S / apt install（如需要安装 Web 服务器）

使用前必须确认

1. ✅ 用户明确授权 — 不要自动执行，必须先向用户说明并获得确认
2. ✅ 备份现有配置 — 修改 Web 服务器配置前务必备份
3. ✅ 测试环境优先 — 首次使用建议在测试环境验证
4. ✅ 了解回滚方案 — 知道如何恢复配置（备份还原、服务重启）

备份命令（执行任何修改前）

# Nginx 配置备份
sudo cp -r /etc/nginx /etc/nginx.backup.$(date +%Y%m%d_%H%M%S)

# Caddy 配置备份  
sudo cp /etc/caddy/Caddyfile /etc/caddy/Caddyfile.backup.$(date +%Y%m%d_%H%M%S)

# Web 根目录备份（如已有内容）
sudo cp -r /var/www/html /var/www/html.backup.$(date +%Y%m%d_%H%M%S)

替代方案（无需 root）

如果不需要系统级部署，考虑：

• 用户级静态服务器：python3 -m http.server 8080
• Node.js: npx serve ./public
• Docker 容器化部署（隔离环境）

Step 0: Detect Web Server

Before deploying, detect which web server is installed and running:

# Check Caddy
command -v caddy && systemctl is-active caddy 2>/dev/null

# Check Nginx
command -v nginx && systemctl is-active nginx 2>/dev/null

Priority: Caddy (if both are running) > Nginx > Neither (prompt user to install one).

Caddy Deployment

Setup (first time only)

Ensure Caddyfile has a static file block. Add if missing:

:80 {
    handle_path /r/* {
        file_server {
            root /var/www/html
        }
    }
}

Then systemctl reload caddy.

Deploy

mkdir -p /var/www/html/<project-name>
cp -r <source-files> /var/www/html/<project-name>/

URL: http://<ip>/r/<project-name>/index.html

No reload needed — files are served instantly.

Nginx Deployment

Setup (first time only)

Create a location block in the Nginx site config (e.g. /etc/nginx/sites-available/default or /etc/nginx/conf.d/static.conf):

server {
    listen 80;
    # ... existing config ...

    location /r/ {
        alias /var/www/html/;
        autoindex off;
        try_files $uri $uri/ =404;
    }
}

Then nginx -t && systemctl reload nginx.

Deploy

mkdir -p /var/www/html/<project-name>
cp -r <source-files> /var/www/html/<project-name>/

URL: http://<ip>/r/<project-name>/index.html

No reload needed — files are served instantly once placed in web root.

Common Steps (both servers)

Get access URL

# Tailscale
tailscale ip -4 2>/dev/null

# Or local IP
hostname -I | awk '{print $1}'

Verify

curl -s -o /dev/null -w "%{http_code}" http://127.0.0.1:80/r/<project-name>/index.html

Expect 200.

Notes

• Web root: /var/www/html/ (shared convention for both Caddy and Nginx)
• URL pattern: http://<ip>/r/<subdir>/ (consistent across both servers)
• Files are served instantly — no reload needed after placing files
• For subdirectories, ensure index.html exists
• Large files (>50MB) should be considered carefully for disk usage
• If neither Caddy nor Nginx is installed, suggest pacman -S caddy / apt install caddy / apt install nginx
