求助，CentOS7的SELinux有几个Alert
大家好，我刚刚重装的centos7(CentOS-7.0-1406-x86_64-DVD.iso)
用yum update之后的版本是：
Linux localhost.localdomain 3.10.0-327.3.1.el7.x86_64 #1 SMP Wed Dec 9 14:09:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
在yum update过程中,SELinux有几个Alert，然后光驱就弹出了. 不知道是不是被攻击？该怎么办？谢谢
我系统的/var/log/audit/audit.log贴在这里了

回复 1# yaoyansi
注意看每个alert 的这几行.比如
allow this access for now by executing:
# grep abrt-handle-eve /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
然后复制红字部分到终端,以root身份运行就可以了.
