Error: Package: 32:bind-libs-9.9.4-50.el7.x86_64 (163-epel)
           Requires: bind-license = 32:9.9.4-50.el7

               bind-license = 32:9.9.4-50.el7
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

分析原因：

系统安装bind这类的rpm包冲突引起，查找安装的是那些包，卸载：

#rpm -qa | grep bind
bind-license-9.9.4-50.el7_3.1.noarch
bind-libs-lite-9.9.4-50.el7_3.1.x86_64

yum remove bind-libs-lite bind-license-9.9.4

重新安装bind-utils

#yum install bind-utils -y
