wipefs进程是啥,占用了百分之90多的cpu
wipefs是linux自带的程序,用来擦除文件系统数据,也就是下面那个人回答的。正常的wipefs,路径在/usr/bin/wipefs,如果你没有做设置,不会自启动,也不会大量占用cpu。你可以看一下是否是 /bin/wipefs 进程,如果是,应该是你的机器被黑了,这是别人在你机器上放了挖矿程序。此程序会:1.进行挖矿计算,大量占用cpu。2.复制自己到/bin/wipefs,创建服务/etc/init.d/wipefs,在 /etc/rc.d 和 /etc/rc.d/rc.d 中创建链接以实现开机启动。3.释放子程序到 /bin/ddus-uidgen,创建服务/etc/init.d/acpidtd,并在 /etc/rc.d 和 /etc/rc.d/rc.d 中创建链接以实现开机启动。4.修改/etc/resolv.conf, 可能是为其连接矿机服务的域名做服务。5.修改/etc/crontab, 为自己创建定时任务,每天12点与0点开始执行。(所以你会发现第二天又启动了)你需要做的:1.删除 /etc/crontab 中的定时任务。2.删除以下文件:/bin/wipefs/etc/init.d/wipefs/bin/ddus-uidgen/etc/init.d/acpidtd/etc/rc0.d/S01wipefs/etc/rc1.d/S01wipefs/etc/rc2.d/S01wipefs/etc/rc3.d/S01wipefs/etc/rc4.d/S01wipefs/etc/rc5.d/S01wipefs/etc/rc6.d/S01wipefs/etc/rc.d/rc0.d/S01wipefs/etc/rc.d/rc1.d/S01wipefs/etc/rc.d/rc2.d/S01wipefs/etc/rc.d/rc3.d/S01wipefs/etc/rc.d/rc4.d/S01wipefs/etc/rc.d/rc5.d/S01wipefs/etc/rc.d/rc6.d/S01wipefs/etc/rc0.d/acpidtd/etc/rc1.d/acpidtd/etc/rc2.d/acpidtd/etc/rc3.d/acpidtd/etc/rc4.d/acpidtd/etc/rc5.d/acpidtd/etc/rc6.d/acpidtd/etc/rc.d/rc0.d/acpidtd/etc/rc.d/rc1.d/acpidtd/etc/rc.d/rc2.d/acpidtd/etc/rc.d/rc3.d/acpidtd/etc/rc.d/rc4.d/acpidtd/etc/rc.d/rc5.d/acpidtd/etc/rc.d/rc6.d/acpidtd检查机器漏洞,ssh权限,防火墙等,避免机器再次被攻击。
