title: nginx fails to load ssl certificate
body: <p>I have to add ssl (https) for a website, I was given a SSL.CSR and a SSL.KEY file.  I 'dos2unix'ed them (because they have trailing ^M) and copied them to the server(CSR -> mywebsite.crt, KEY -> mywebsite.key).  I did the following modification to nginx.conf:</p>

  <p>Error happens when I restart nginx:</p>
  
  <pre><code>nginx: [emerg] PEM_read_bio_X509_AUX("/etc/nginx/mywebsite.crt") failed (SSL: error:0906D06C:PEM routines:PEM_read_bio:no start line:Expecting: TRUSTED CERTIFICATE)
  </code></pre>
  
  <p>I figure it's because the first line of mywebsite.crt file contains 'REQUEST', so I remove 'REQUEST' from the first and last of the lines, and restart nginx again, and hit another error:</p>

  <p>Any idea?</p>
