title: Gitlab-CI with Gitlab setup, self-hosted
body: <p>I have setup Gitlab in ubuntu server, it's working fine. I access Gitlab by url <code>http://123.456.789.100</code> and Gitlab login details</p>
  
  <pre><code> username:admin@local.host 
   password:123456
  </code></pre>
  
  <p>Then I wanted to set Gitlab CI for test the code before it merge. I have done with setting Gitlab CI by using the link. I have done setting up every thing except Runners. While set <code>ssh git@&lt;your gitlab url&gt;</code> in Runner I face error</p>
  
  <pre><code> ssh git@123.456.789.100
   it prompts me for password
  </code></pre>
  
  <p>git@123.456.789.100's password:
  I entered password(123456) of gitlab's that I used to enter into gitlab server, then I have this error</p>
  
  <pre><code>Permission denied please try again
  </code></pre>
  
  <p>But I got Gitlab CI web interface by <code>http://123.456.789.100:8081</code>(I did set Gitlab-ci to listen on 8081 port). Then I entered Gitlab server's username and password as admin@local.host and 123456, I got Invalid credentials.</p>
  
  <p>What would be the wrong I made?</p>
