# Momentry 系統服務安裝與管理指南

## 概述

本文檔記錄 momentry 系統所需的所有服務，包括安裝步驟、健康檢查和管理命令。

**重要**: 請勿使用 `brew services` 命令管理服務，否則可能導致 .plist 檔案還原為預設狀態，造成系統異常。請使用 `launchctl` 命令進行管理。

## 必要服務 (Momentry 核心)

### 1. PostgreSQL

#### 安裝
```bash
# 檢查是否已安裝
brew list postgresql@18 2>/dev/null || echo "Not installed"

# 安裝 PostgreSQL 18
brew install postgresql@18

```bash
# 初始化資料庫 (如尚未初始化)
initdb /usr/local/var/postgresql@18

# 建立 momentry 資料庫
createdb -U accusys momentry
```

#### 開機自動啟動
```bash
# 建立 plist 檔案
sudo tee /Library/LaunchDaemons/com.momentry.postgresql.plist > /dev/null <<'EOF'
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

</dict>
</plist>
EOF

# 載入服務
sudo launchctl load /Library/LaunchDaemons/com.momentry.postgresql.plist
```

#### 管理命令
```bash
# 啟動
sudo launchctl load /Library/LaunchDaemons/com.momentry.postgresql.plist

# 停止
sudo launchctl unload /Library/LaunchDaemons/com.momentry.postgresql.plist

# 重新載入
sudo launchctl unload /Library/LaunchDaemons/com.momentry.postgresql.plist
sudo launchctl load /Library/LaunchDaemons/com.momentry.postgresql.plist
```

#### 健康檢查
```bash
# 方法 1: 使用 pg_isready
pg_isready -h localhost -p 5432 -U accusys

# 方法 2: 連線測試
psql -U accusys -h localhost -d momentry -c "SELECT 1;"

# 方法 3: 檢查程序
pgrep -f "postgres.*postgresql@18"
```

requirepass accusys

# 或使用環境變數方式啟動
```

#### 開機自動啟動
```bash
# 建立 plist 檔案
sudo tee /Library/LaunchDaemons/com.momentry.redis.plist > /dev/null <<'EOF'
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

sudo launchctl load /Library/LaunchDaemons/com.momentry.postgresql.plist

# Redis, Ollama (需要 root 權限)
sudo launchctl load /Library/LaunchDaemons/com.momentry.redis.plist
sudo launchctl load /Library/LaunchDaemons/com.momentry.ollama.plist

# n8n (需要 root 權限)
sudo launchctl load /Library/LaunchDaemons/com.momentry.n8n.main.plist
sudo launchctl load /Library/LaunchDaemons/com.momentry.n8n.worker.plist
```

### 停止服務
```bash
# PostgreSQL
sudo launchctl unload /Library/LaunchDaemons/com.momentry.postgresql.plist

# Redis, Ollama
sudo launchctl unload /Library/LaunchDaemons/com.momentry.redis.plist
sudo launchctl unload /Library/LaunchDaemons/com.momentry.ollama.plist

# n8n
sudo launchctl unload /Library/LaunchDaemons/com.momentry.n8n.main.plist
sudo launchctl unload /Library/LaunchDaemons/com.momentry.n8n.worker.plist
```

### 查詢服務狀態
```bash
# 查看所有服務
launchctl list | grep -E "(postgres|redis|ollama|n8n|grafana|prometheus)"

# 查看特定服務
launchctl list | grep com.momentry
```

---

## 故障排除

### PostgreSQL 問題

```bash
# 查看日誌
tail -f /opt/homebrew/var/postgresql@18/logfile

# 重新初始化
pg_ctl -D /opt/homebrew/var/postgresql@18 stop
rm -rf /opt/homebrew/var/postgresql@18
initdb -D /opt/homebrew/var/postgresql@18

# 重建資料庫
dropdb momentry
createdb -U accusys momentry
```

### Redis 問題

```bash
# 查看日誌
tail -f /opt/homebrew/var/log/redis.log

# 測試連線
redis-cli -a accusys DEBUG SLEEP 1

# 重新整理 ACL
redis-cli -a accusys FLUSHALL
```

### Ollama 問題

```bash
# 查看日誌
tail -f ~/.ollama/logs/server.log

# 重新下載模型
ollama pull mistral:latest
ollama pull nomic-embed-text:latest

# 檢查 GPU 使用情況
ollama list
```
