AI小龙虾OpenClaw数据库集成指南-第1张图片-OpenClaw 中文版 - 真正能做事的 AI

# 安装PostgreSQL
sudo apt update
sudo apt install postgresql postgresql-contrib
# 启动服务
sudo systemctl start postgresql
sudo systemctl enable postgresql
# 创建OpenClaw数据库和用户
sudo -u postgres psql

PostgreSQL SQL命令:

-- 创建数据库
CREATE DATABASE openclaw_db;
-- 创建用户
CREATE USER openclaw_user WITH PASSWORD 'your_secure_password';
-- 授予权限
GRANT ALL PRIVILEGES ON DATABASE openclaw_db TO openclaw_user;
-- 设置扩展（用于向量搜索）
\c openclaw_db
CREATE EXTENSION IF NOT EXISTS vector;
CREATE EXTENSION IF NOT EXISTS pg_trgm;

2 MySQL安装与设置

Ubuntu/Debian:

# 安装MySQL
sudo apt update
sudo apt install mysql-server
# 安全配置
sudo mysql_secure_installation
# 启动服务
sudo systemctl start mysql
sudo systemctl enable mysql

MySQL SQL命令:

-- 创建数据库
CREATE DATABASE openclaw_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
-- 创建用户
CREATE USER 'openclaw_user'@'localhost' IDENTIFIED BY 'your_secure_password';
-- 授予权限
GRANT ALL PRIVILEGES ON openclaw_db.* TO 'openclaw_user'@'localhost';
FLUSH PRIVILEGES;

3 Redis安装

# 安装Redis
sudo apt update
sudo apt install redis-server
# 配置Redis
sudo nano /etc/redis/redis.conf
# 修改以下配置：
# maxmemory 256mb
# maxmemory-policy allkeys-lru
# 重启服务
sudo systemctl restart redis
sudo systemctl enable redis

OpenClaw数据库配置

1 配置文件设置

编辑 config/database.yml (或 .env 文件):

# PostgreSQL配置示例
production:
  adapter: postgresql
  encoding: unicode
  database: openclaw_db
  pool: 5
  username: openclaw_user
  password: <%= ENV['OPENCLAW_DATABASE_PASSWORD'] %>
  host: localhost
  port: 5432
# 或MySQL配置
production:
  adapter: mysql2
  encoding: utf8mb4
  database: openclaw_db
  username: openclaw_user
  password: <%= ENV['OPENCLAW_DATABASE_PASSWORD'] %>
  host: localhost
  port: 3306

2 环境变量配置

创建 .env 文件：

# 数据库配置
DB_HOST=localhost
DB_PORT=5432
DB_NAME=openclaw_db
DB_USER=openclaw_user
DB_PASSWORD=your_secure_password
# Redis配置
REDIS_URL=redis://localhost:6379/0
REDIS_CACHE_URL=redis://localhost:6379/1
# 可选：向量数据库
PINECONE_API_KEY=your_pinecone_key
PINECONE_ENVIRONMENT=us-west1-gcp

数据库迁移与初始化

1 运行数据库迁移

# 进入OpenClaw安装目录
cd /path/to/openclaw
# 安装依赖
pip install -r requirements.txt
# 或使用poetry
poetry install
# 运行迁移
python manage.py migrate
# 或使用alembic（如果使用SQLAlchemy）
alembic upgrade head
# 创建超级用户
python manage.py createsuperuser

2 初始化数据

# 加载初始数据
python manage.py loaddata initial_data.json
# 或运行初始化脚本
python scripts/init_database.py

数据库优化配置

1 PostgreSQL优化

编辑 /etc/postgresql/版本/main/postgresql.conf：

# 内存设置
shared_buffers = 256MB
work_mem = 16MB
maintenance_work_mem = 64MB
# 并行设置
max_worker_processes = 8
max_parallel_workers_per_gather = 4
# WAL设置
wal_buffers = 16MB
min_wal_size = 1GB
max_wal_size = 4GB
# 连接设置
max_connections = 100

2 MySQL优化

编辑 /etc/mysql/my.cnf：

[mysqld]
# 内存设置
innodb_buffer_pool_size = 256M
innodb_log_file_size = 64M
key_buffer_size = 128M
# 连接设置
max_connections = 100
thread_cache_size = 8
# 查询缓存
query_cache_type = 1
query_cache_size = 32M

备份与恢复

1 备份脚本

创建 scripts/backup.sh：

#!/bin/bash
BACKUP_DIR="/var/backups/openclaw"
DATE=$(date +%Y%m%d_%H%M%S)
# PostgreSQL备份
pg_dump -U openclaw_user -h localhost openclaw_db > \
  $BACKUP_DIR/openclaw_db_$DATE.sql
# 压缩备份
gzip $BACKUP_DIR/openclaw_db_$DATE.sql
# 保留最近7天备份
find $BACKUP_DIR -name "*.gz" -mtime +7 -delete

2 恢复数据库

# 解压备份文件
gunzip openclaw_db_20240101_120000.sql.gz
# 恢复PostgreSQL
psql -U openclaw_user -h localhost openclaw_db < openclaw_db_20240101_120000.sql
# MySQL恢复
mysql -u openclaw_user -p openclaw_db < backup_file.sql

监控与维护

1 监控命令

# 检查数据库连接
python manage.py check --database default
# 查看数据库状态
# PostgreSQL
psql -U openclaw_user -h localhost -c "SELECT version();"
psql -U openclaw_user -h localhost -c "\l"
psql -U openclaw_user -h localhost -c "\dt"
# MySQL
mysql -u openclaw_user -p -e "SHOW DATABASES;"
mysql -u openclaw_user -p -e "SHOW TABLES FROM openclaw_db;"
# Redis
redis-cli ping
redis-cli info

2 定期维护任务

创建 scripts/maintenance.py：

#!/usr/bin/env python
import subprocess
import schedule
import time
def vacuum_database():
    """定期清理数据库"""
    # PostgreSQL VACUUM
    subprocess.run([
        'psql', '-U', 'openclaw_user',
        '-h', 'localhost',
        '-d', 'openclaw_db',
        '-c', 'VACUUM ANALYZE;'
    ])
def clear_redis_cache():
    """清理Redis缓存"""
    subprocess.run([
        'redis-cli', 'FLUSHDB'
    ])
if __name__ == "__main__":
    # 每天凌晨3点执行
    schedule.every().day.at("03:00").do(vacuum_database)
    schedule.every().sunday.at("04:00").do(clear_redis_cache)
    while True:
        schedule.run_pending()
        time.sleep(60)

故障排除

常见问题及解决方案

连接失败

# 检查服务状态
sudo systemctl status postgresql
sudo systemctl status mysql
sudo systemctl status redis
# 检查端口
netstat -tulpn | grep -E '5432|3306|6379'
# 检查防火墙
sudo ufw status

权限问题

-- PostgreSQL权限检查
\du openclaw_user
-- 重新授权
GRANT ALL PRIVILEGES ON DATABASE openclaw_db TO openclaw_user;

性能问题

-- 查看慢查询
-- PostgreSQL
SELECT * FROM pg_stat_activity WHERE state = 'active';
-- MySQL
SHOW PROCESSLIST;
SET GLOBAL slow_query_log = 'ON';

高级配置（可选）

1 配置读写分离

# config/database.yml
production:
  primary:
    adapter: postgresql
    host: primary-db.example.com
    username: openclaw_user
    password: <%= ENV['DB_PASSWORD'] %>
    database: openclaw_db
  replica:
    adapter: postgresql
    host: replica-db.example.com
    username: openclaw_user
    password: <%= ENV['DB_PASSWORD'] %>
    database: openclaw_db
    replica: true

2 配置连接池

# 数据库连接池配置
DATABASE_POOL = {
    'max_overflow': 10,
    'pool_size': 5,
    'pool_recycle': 3600,
    'pool_timeout': 30
}

安全建议

使用强密码：至少16位，包含大小写字母、数字和特殊字符
定期更新密码：每90天更换一次数据库密码
限制访问IP：仅允许应用服务器访问数据库
启用SSL连接：加密数据库连接
定期审计：检查数据库日志和访问记录

重要提示：生产环境部署前，请务必进行完整备份并在测试环境验证所有配置，建议咨询数据库管理员进行生产环境优化。
