title: Can't open the mysql.plugin table. Please run mysql_upgrade to create it
body: <p>I have downloaded mysql ZIP from here <a href="https://dev.mysql.com/downloads/file/?id=467269" rel="noreferrer">https://dev.mysql.com/downloads/file/?id=467269</a></p>
  
  <p>Then extracted it, renamed <code>my-default.ini</code> to <code>my.ini</code>, set </p>
  
  <pre><code>basedir = D:\Apps\MySQL\mysql-5.7.17-winx64
  datadir = D:\Apps\MySQL\data5717
  </code></pre>
  
  <p>then started </p>
  
  <pre><code>mysqld --console
  </code></pre>
  
  <p>under admin privileges. All was described here: <a href="http://dev.mysql.com/doc/refman/5.7/en/windows-install-archive.html" rel="noreferrer">http://dev.mysql.com/doc/refman/5.7/en/windows-install-archive.html</a></p>
  
  <p>Unfortunately it prints the following in console:</p>
  
  <blockquote>
    <p>[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to
    create it.</p>
  </blockquote>
  
  <p>and doesn't work.</p>
