移动站点流量异常排查官方文档

移动站点流量异常排查官方文档： 1. 检查服务器负载情况： CPU、内存、磁盘的使用率是否高，如果高，可能是服务器存在性能问题导致网站响应缓慢，或者需要升级服务器配置。 2. 检查网络带宽：如果服务器带宽和流量限制过低，会导致访问速度慢，建议升级网络带宽和流量限制。 3. 网站文件冗余：检查站点文件是否存在重复或者删除不完全的文件，删除冗余文件可以减少服务器负担。 4. DNS解析：如果DNS解析失败或者解析速度过慢，可能导致用户无法正常访问网站，建议更换可靠的DNS服务器。 5. 网络攻击：可能会面临大规模DDoS攻击，影响站点访问速度，安装防火墙或CDN可以缓解网络攻击带来的影响。 6. CDN加速：建议使用CDN加速技术，将静态文件和大文件发布到CDN节点，减少对服务器负载的影响，并提高访问速度。 7. 程序性能：仔细检查程序，是否存在死循环、资源占用等性能问题，尽可能地优化程序性能。 8. 数据库优化：检查站点数据库是否需要优化，如数据索引、查询语句等，数据库启用缓存机制也可以提高站点性能。 9. 预防SQL注入攻击：对于具有提交表单功能的站点，特别注意输入内容的合法性，防范SQL注入攻击。 10. 监控系统：配置网站监控系统，定期检查站点性能和流量情况，及时发现并解决潜在问题。
