# Install Homebrew (if not already installed)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Ollama
brew install ollama

# Start as background service (auto-starts on reboot)
brew services start ollama

# Verify it's running
curl http://localhost:11434/api/version

# Allow Ollama to listen on all interfaces (not just localhost)
echo 'export OLLAMA_HOST=0.0.0.0:11434' >> ~/.zshrc
echo 'export OLLAMA_MAX_LOADED_MODELS=3' >> ~/.zshrc
echo 'export OLLAMA_KEEP_ALIVE=1h' >> ~/.zshrc
source ~/.zshrc

# Restart Ollama with new settings
brew services restart ollama

# Verify listening on all interfaces
lsof -i :11434

# General-purpose LLM
ollama pull llama3.1:8b

# Alternative: faster, similar quality
ollama pull mistral:7b

# For coding tasks
ollama pull deepseek-coder-v2:16b

# Embedding model for RAG
ollama pull nomic-embed-text

# Find current local IP
ipconfig getifaddr en0

# Or use Bonjour - access at hostname.local
scutil --get LocalHostName
# 示例：macmini → 通过 http://macmini.local:11434 访问

sudo pmset -a sleep 0
sudo pmset -a displaysleep 1
sudo pmset -a powernap 0
sudo pmset -a hibernatemode 0

# Verify settings
pmset -g

# 从同一网络的笔记本/手机/平板：
curl http://macmini.local:11434/api/chat -d '{
  "model": "llama3.1:8b",
  "messages": [{"role": "user", "content": "来自手机的问候！"}]
}'

# 方案1：Tailscale（推荐）— 安装在Mac Mini上
brew install --cask tailscale
# 通过Tailscale应用登录 — Mac Mini获得私有IP
# 从任何安装了Tailscale的地方访问：
curl http://macmini.tailnet.ts.net:11434/api/chat -d '{...}'

# 方案2：Cloudflare Tunnel（Web访问）
brew install cloudflared
cloudflared tunnel create ai-server
cloudflared tunnel route dns ai-server ai.yourdomain.com
# 从任何地方通过 https://ai.yourdomain.com 访问

# 通过Docker安装ChromaDB
brew install --cask docker
docker run -d -p 8000:8000 -v ~/chromadb:/data chromadb/chroma

# 索引文档（Python）
