body: <p>I want to restart httpd aws ec2 linux. I write following command in terminal.</p>
  
  <pre><code>  sudo service httpd restart 
  </code></pre>
  
  <p>But it gives me following error.</p>

  <p>If i comment the line then it will show below error.</p>

  <p>I dont think so that each time i have to comment the lines.
  Currently, i dont need ssl.conf. 
  So i dont want to call it when i am going to restart httpd.
  how can i do it?</p>
  
  <p>Thanks</p>
