yum groupinstall “Network Infrastructure Server”

So when I recently tried to install the Network Infrastructure Server on CentOS 6.5, yum replied with a rather unhelpful error message.

[root@localhost ~]# yum groupinstall "Network Infrastructure Server"
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: ftp.osuosl.org
 * extras: mirrordenver.fdcservers.net
 * updates: mirrordenver.fdcservers.net
Setting up Group Process
Checking for new repos for mirrors
Warning: Group network-server does not have any packages.
No packages in any requested group available to install or update

Well that was useful right? When you run a yum groupinfo “Network Infrastructure Server” you will notice there are not mandatory packages, just optional packages.

[root@localhost ~]# yum groupinfo "Network Infrastructure Server"
Loaded plugins: fastestmirror

Group: Network Infrastructure Server
 Description: Servers for core network protocols and services, such as DHCP or DNS.
 Optional Packages:
   bind
   bind-chroot
   bind-dyndb-ldap
   dhcp
   dnsmasq
   freeradius
   quagga
   radvd
   rsyslog-gnutls
   rsyslog-gssapi
   rsyslog-mysql
   rsyslog-pgsql
   rsyslog-relp
   syslinux
   tftp-server
I did some Google searches on this and came up with a few unhelpful answers. In short, my final solution was a simple one-liner: **yum groupinfo “Network Infrastructure Server” egrep “\s{3}” xargs yum install -y** 
[root@localhost ~]# yum groupinfo "Network Infrastructure Server"|egrep "\s{3}"|xargs yum install -y
