title: can't install using yum in RHEL 7.1
body: <p>I got a RHEL 7.1 instance on amazon aws, now i am trying to install softwares using yum, but even very common softwares aren't available.</p>
  
  <p>For example,</p>
  
  <p><code>$ sudo yum install lynx</code></p>
  
  <pre><code>Loaded plugins: amazon-id, rhui-lb
  No package lynx available.
  Error: Nothing to do
  </code></pre>
  
  <p>I am new to linux and <code>yum</code>. What's to be done so I can install softwares easily using <code>yum</code>.</p>
  
  <p>Should I be adding repos?</p>
  
  <p>Here, I tried doing what's said here -> <a href="http://tecadmin.net/top-5-yum-repositories-for-centos-rhel-systems/" rel="nofollow">Top 5 Yum Repositories for CentOS/RHEL 7/6/5 and Fedora</a>, and here -> <a href="http://www.unixmen.com/install-repoforge-rpmforge-repository-rhel-centos-scientific-linux-76-x5-x4-x/" rel="nofollow">Install RepoForge (RPMForge) Repository On RHEL, CentOS, Scientific Linux 7/6.x/5.x/4.x</a> but to no use.</p>
  
  <p>Appreciate any help.</p>
