title: Install GitLab on Subdomain
body: <p>I am trying to install GitLab on a subdomain. I am not very familiar with web servers and stuff, only very little knowledge. I am currently connected to the subdomain via <code>ssh admin@mysite.com</code> on the Mac's Terminal. Then I <code>ls</code> to the subdomain's folder. Question is if I execute:</p>
  
  <pre><code>curl -O https://downloads-packages.s3.amazonaws.com/centos-6.5/gitlab-7.4.3_omnibus.5.1.0.ci-1.el6.x86_64.rpm
  sudo yum install openssh-server
  sudo yum install postfix
  sudo yum install cronie
  sudo service postfix start
  sudo chkconfig postfix on
  sudo rpm -i gitlab-7.4.3_omnibus.5.1.0.ci-1.el6.x86_64.rpm
  </code></pre>
  
  <p>on the current folder. Will GitLab be installed or downloaded only in the current folder or will other subdomains and folders of the site be affected?</p>
  
  <p>Is there a way to test <code>yum install</code> first on the current directory?</p>
