openclaw config set db.host localhost
# 其他必要配置…

# 重启服务
systemctl restart openclaw
“`

## 预防措施

### 1. 定期备份

“`bash
# 创建配置备份
openclaw backup config

# 创建数据备份
openclaw backup data
“`

### 2. 监控设置

“`yaml
# /etc/openclaw/monitoring.yaml
monitoring:
enabled: true
interval: 60s
alerts:
service_down:
enabled: true
threshold: 3
high_cpu:
enabled: true
threshold: 80
high_memory:
enabled: true
threshold: 85
“`

### 3. 自动恢复机制

“`bash
# 创建自动恢复脚本
cat > /usr/local/bin/openclaw_recovery.sh << 'EOF' #!/bin/bash # 检查服务状态 if ! systemctl is-active --quiet openclaw; then echo "$(date): OpenClaw service is down, attempting to restart..." systemctl restart openclaw # 检查重启是否成功 sleep 5 if systemctl is-active --quiet openclaw; then echo "$(date): OpenClaw service restarted successfully" else echo "$(date): OpenClaw service failed to restart" # 发送告警 curl -X POST -H "Content-Type: application/json" \ -d '{"message": "OpenClaw service failed to restart"}' \ https://your-alert-system.com/webhook fi fi EOF # 设置执行权限 chmod +x /usr/local/bin/openclaw_recovery.sh # 添加到 cron 任务 (crontab -l 2>/dev/null; echo “*/5 * * * * /usr/local/bin/openclaw_recovery.sh >> /var/log/openclaw_recovery.log 2>&1”) | crontab –
“`

## 故障排查流程

1. **检查服务状态**:`systemctl status openclaw`
2. **查看日志**:`journalctl -u openclaw`
3. **测试 API 可用性**:`curl -X GET http://localhost:8080/api/health`
4. **检查资源使用**:`top` 或 `htop`
5. **验证配置**:`openclaw config validate`
6. **尝试重启**:`systemctl restart openclaw`
7. **恢复备份**:如果问题严重,使用 `openclaw restore`

## 最佳实践

– **定期更新**:保持 openclaw 版本最新
– **监控到位**:设置完善的监控和告警机制
– **备份策略**:定期备份配置和数据
– **灾备方案**:制定详细的灾难恢复计划
– **文档记录**:记录故障处理过程和解决方案

通过以上措施,可以有效提高 openclaw 的可靠性和稳定性,确保在遇到故障时能够快速恢复,减少服务中断时间。
