title: php-fpm refuses to start (missing path /usr/var)
body: <p>In the default php-fpm.conf file that comes with OS X, it says "the default prefix is /usr/var". However, this path does not exist on OS X, so php-fpm refuses to start.</p>
  
  <p>I was able to remedy the situation by setting the <code>error_log = syslog</code>, but what is the best way to handle this situation? Simply create the missing directory?</p>
  
  <p>All these UNIX path conventions are a bit of a blur to me.</p>
  
  <pre><code>; Error log file
  ; If it's set to "syslog", log is sent to syslogd instead of being written
  ; in a local file.
  ; Note: the default prefix is /usr/var
  ; Default Value: log/php-fpm.log
  ;error_log = log/php-fpm.log
  </code></pre>
