服务器安全与病毒 kdevtmpfsi病毒（redis开启远程访问后，又是弱口令导致中redis勒索挖矿病毒）现象：cpu一直100%飙满解决：top命令或FinalShell软件查cpu和内存情况kdevtmpfsi 病毒 和他的守护进程kinsing和恶意程序red2.so全局查找删干净，包括定时任务 crontab 会恢复病毒程序，一起删了病毒导致内存吃满卡机，服务器瘫痪现象：ssh连接上去后，几秒钟程序就内存吃满后卡死，无法输入命令，一直断线，重启无果，导致服务器瘫痪，无法做任何操作，只有刚连接进去后的5秒的有效操作时间（病毒未吃满内存前），5秒钟以后内容爆满系统卡死断开连接，并且top命令和系统监控工具全被删除，无法使用，无法找到占内存的进程解决：ps aux --sort -rss | head 命令查找前几秒一瞬间的运行程序，发现几百个top.original进程在大量吃内存，发现恶意程序，删除以后内存恢复，但是被删top无法恢复，只能装 htop等类似软件使用完成后最好安装阿里云骑士，安全中心全局扫描隐藏病毒，否则会恢复（第一次就是没删干净有隐藏恢复程序导致第二次服务器瘫痪）总结经验：1.数据库，redis，ftp等能不开远程连接就不开，开了也得密码强度要高默认端口也得改，并且SSH默认默认端口也得改，防止暴力破解2.定期备份数据库和服务器系统
