title: Mysql 5.7 - CentOS Init error : initialize specified but the data directory has files in it. Aborting
body: <p>I'm having an issue with my MySQL 5.7 install on CentOS 7.</p>
  <p>When I'm trying to start the service:</p>
  <blockquote>
  <p>initialize specified but the data directory has files in it. Aborting</p>
  </blockquote>
  <p>Which is weird because it's empty:</p>
  <p>my.cnf:</p>
  <pre><code>tmpdir                         = /home5/mysql/MYP015RANB/tmp
  datadir                        = /home4/mysql/MYP015RANB/data
  </code></pre>
  <p>/home4 is empty.</p>
  <p>I already tried to delete my instance / remove MySQL / reinstall everything.</p>
  <p>Any ideas?</p>
