报错原因：nagios.tar.gz是32位程序，需要的32位包nss-softokn-freebl-3.14.3-9.el6.i686安装不上，因为已经安装了nss-softokn-freebl-3.14.3-10.el6_5.x86_64，而实际上需要的是nss-softokn-freebl-3.14.3-10.el6.x86_64

i686的版本必须要和64位的版本一致才能安装（比如nss-softokn-freebl的3.14.3-9.el6 要等于 3.14.3-10.el6，后面的次版本号可以不一样，-9和-10可以不一样），需要将 nss-softokn-freebl-3.14.3-10.el6_5.x86_64的版本升级，并且不带el6_5,解决方法，在网上下载nss-softokn-freebl-3.14.3-17.el6.i686.rpm nss-softokn-freebl-3.14.3-17.el6.x86_64.rpm
