网站经常被人攻击怎么办！
还是万网云主机，简直防御不了，我也没有得罪过谁，只是网站，流量极速增加！
我有更好的答案
1，流量攻击，就是我们常说的DDOS和DOS等攻击，这种攻击属于最常见的流量攻击中的带宽攻击，一般是使用大量数据包淹没一个或多个路由器、服务器和防火墙，使你的网站处于瘫痪状态无法正常打开。但是这种攻击成本都会很高.2， CC攻击，也是流量攻击的一种，CC就是模拟多个用户（多少线程就是多少用户）不停地进行访问那些需要大量数据操作（就是需要大量CPU时间）的页面，造成服务器资源的浪费，CPU长时间处于100%，永远都有处理不完的连接直至就网络拥塞，正常的访问被中止。而CC攻击基本上都是针对端口的攻击，以上这两种攻击基本上都属于硬性流量的攻击.如果服务器（网站）被入侵了,一般都是服务器或者网站存在漏洞，被黑客利用并提权入侵的，导致服务器中木马，网站被挂黑链，被篡改，被挂马。解决办法：如果程序不是很大，可以自己比对以前程序的备份文件，然后就是修复，或者换个服务器，最好是独立服务器。也可以通过安全公司来解决，国内也就Sinesafe和绿盟等安全公司 比较专业.我是从事IDC行业的.以上这些也是平时工作中经常遇到的问题.希望我的回答对你有所帮助.

出门在外也不愁linux云服务器 CPU跑满99% 根据日志排查原因 | AnFay
查看linux日志
查看最近更新时间来判断查看哪个日志
根据日志排查原因
tail -f /var/log/maillog
ctrl+c 或者 ctrl+z
此次CPU跑满99%，是因为
maillog日志文件中每10分钟出现一条错误日志
