复制代码

添加执行权限：

sudochmod +x /usr/local/bin/nuc-remote-management.sh

复制代码

配置定时任务：

crontab -e
# 添加每 10 分钟执行一次管理
*/10 * * * * /usr/local/bin/nuc-remote-management.sh

复制代码

九、故障排查

9.1 网络连接问题

# 检查网络接口ip addr show
# 检查网络连接ping8.8.8.8
# 检查 DNS 解析nslookup google.com
# 重启网络服务sudo systemctl restart networking
# 检查路由表ip route show

复制代码

9.2 SSH 连接问题

# 检查 SSH 服务状态sudo systemctl status ssh# 查看 SSH 日志sudo journalctl -u ssh -n 50# 重启 SSH 服务sudo systemctl restart ssh# 检查 SSH 配置sudo sshd -t
# 检查防火墙sudo ufw status

复制代码

9.3 Docker 服务问题

# 检查 Docker 服务状态sudo systemctl status docker# 查看 Docker 日志sudo journalctl -u docker -n 50# 重启 Docker 服务sudo systemctl restart docker# 检查 Docker 版本docker --version
# 测试 Dockerdocker run hello-world

复制代码

9.4 OpenClaw 服务问题

# 检查 OpenClaw 服务状态cd /opt/openclaw/openclaw
docker-composeps# 查看 OpenClaw 日志docker-compose logs -f
# 重启 OpenClaw 服务docker-compose restart
# 重新构建 OpenClawdocker-compose up -d --build
# 检查容器资源使用docker stats

复制代码
