有了这些变化，CPU的使用应该会稳定下来。请在几天内告诉我们您的进度。好的，所以我最终能够找到问题所在
一些流行SEO工具的爬虫以很高的频率请求不存在的URL，导致一些进程在Pimcore中被触发。这就是导致CPU和RAM消耗增加的原因
在通过.htaccess阻止这些爬虫程序后，一切都恢复正常。为您的操作系统创建并启用4GB交换空间。最好慢一段时间运行，而不是“断开”。您知道为什么文件会丢失吗？您能让它们重新联机吗？每个孩子的最大连接数可能在30而不是3000。来自MySQL command提示，显示全局状态，如“max_used_connections”；将结果乘以3，用于Apache max客户端。其他信息请求。MySQL主机服务器上的任何SSD或NVME设备？在pastebin.com上发布并共享链接。从SSH登录根目录，文本结果为：B）显示全局状态；在至少24小时正常运行后C）显示全局变量；D）显示完整的PROCESSLIST；E）完整的MySQLTuner报告和可选的非常有用的信息，如果可用，包括-htop或top用于大多数活动应用程序，ulimit-a用于Linux/Unix限制列表，iostat-xm 5 3用于按设备和核心/cpu计数计算的IOPS，用于服务器工作负载优化分析以提供建议。Have您已通过SHOW CREATE TABLE tbl_name验证；您的索引在新服务器上的表上，就像在旧服务器上一样？您好，威尔逊，谢谢您的帮助！以下是请求的文本结果：B）C）D）e）谢谢，建议已在5月2日20日16:30左右的回答中发布。@nik isschick您有机会实现这些建议吗他建议：当时间允许时，请考虑投票或接受。评论正面或负面对社区是有益的。最后，没有一个建议能奏效。问题是一些爬虫经常请求不存在的URL。不知怎么的，这导致CMS反应过度，导致CPU和RAM消耗。n感谢您的输入！太好了。有了建议，您的查询完成时间应该会更快。
