title: No temporary password in mysqld.log
body: <p>I used mysql 5.7.16 community and centos 7.</p>
  
  <p>I'm following a video <a href="http://www.youtube.com/watch?v=L2m3BM28Mz0" rel="noreferrer">tutorial</a> to install mysql: </p>
  
  <ol>
  <li>wget <a href="http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm" rel="noreferrer">http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm</a></li>
  <li>yum localinstall dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm</li>
  <li>yum repolist enabled | grep "mysql.<em>-community.</em>"</li>
  <li>yum install mysql-community-server</li>
  <li>service mysqld start</li>
  </ol>
  
  <p>After starting mysql, I can see status is alive (running) with <code>service mysqld status</code>.</p>
  
  <p>But I can' get anything by: <code>grep 'temporary password' /var/log/mysqld.log</code></p>
  
  <p>msyqld.log (ignore normal logs):</p>
