title: MySQL slow queries aren't logged
body: <p>In my CentOS machine I use MySQL 5.5.30. (I rented server two days ago and I'm newbie in Linux commands)</p>
  
  <p>I'm trying to check for slow MySQL queries. So I made this from phpMyAdmin</p>
  
  <pre><code>SET GLOBAL log_slow_queries = ON;
  SET GLOBAL slow_launch_time = 1;
  FLUSH LOGS;
  </code></pre>
  
  <p>And in default configuration <code>slow query log file</code> variable is <code>/var/lib/mysql/srv1-slow.log</code></p>
  
  <p>But when I check <code>/var/</code> folder with FTP, there exists only <code>/var/tmp/</code> folder. which is empty. What should I do more to see slow queries log?</p>
  
  <p>Note: I tried to create <code>/var/lib</code> folder but system didn't let me.</p>
