二.检测系统是否感染后门或恶意软件
安装完成后运行rkhunter会出现帮助信息

1.为基本系统程序建立校对样本，建议系统安装完成后就建立。

 执行命令：

 rkhunter --propupd

 ls /var/lib/rkhunter/db/rkhunter.dat #样本文件位置

2.查杀后门执行命令：
 rkhunter --check
只显示报警信息可以运行
rkhunter -c --rwo （report-warnings-only，只显示报警信息）
扫描完成后会生成一份日志存放在/var/log/rkhunter.log
3.在线升级rkhunter

 rkhunter是通过一个含有rootkit名字的数据库来检测系统的rootkits漏洞, 所以经常更新该数据库非常重要, 你可以通过下面命令来更新该数据库:

 执行命令：

 rkhunter --update

4.检测最新版本

让 rkhunter 保持在最新的版本；

执行命令：

rkhunter --versioncheck
