title: MongoDB "Unrecognized option: net.ssl.PEMKeyFile"
body: <p>I'm using MongoDB v3.0.0 with the following configuration file: </p>
  
  <pre><code>storage:
     dbPath: "/home/vagrant/backend/mongodata"
     engine: wiredTiger
  
  systemLog:
     destination: file
     path: "/home/vagrant/backend/log/mongo.log"
     logAppend: true
  
  net:
     port: 27017
     # Enable the HTTP interface (Defaults to port 28017).
     http:
        enabled: false
     ssl:
        mode: requireSSL
        PEMKeyFile: /home/vagrant/backend/keys/privKeys.pem
  
  security:
     authorization: 'enabled'
  </code></pre>
  
  <p>But when I start it up, I get the following error:</p>
  
  <p><code>Unrecognized option: net.ssl.PEMKeyFile
  try '/home/vagrant/backend/mongo/bin/mongod --help' for more information</code></p>
  
  <p>It looks like I have it set up pretty much exactly like they recommend in the docs: <a href="https://docs.mongodb.com/manual/tutorial/configure-ssl/" rel="nofollow noreferrer">https://docs.mongodb.com/manual/tutorial/configure-ssl/</a> . The docs say this is new in mongo 3.0, so it should support this option. It does say certain distributions still don't support it (bizarrely), so I should include that I installed mongo via this: <a href="https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.0.tgz" rel="nofollow noreferrer">https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.0.tgz</a> . The closest info I could find is the MongoDB Download Center saying version 3.0.14 for linux "has been compiled with SSL enabled and dynamically linked. This requires that SSL libraries be installed seperately. See here for more information on installing OpenSSL."</p>
  
  <p>Any idea what might be going wrong here? </p>
