title: Where can I find the centos firewall log file?
body: <p>I have some ports block by firewall when i set my centos server, such as gerrit can't send email by timeout error when I stop firewalld service, it works. And same as shadowsocks, when I start firewalld service, I can't get anything by my server. I have already opened server port 8388 &amp; 8389 &amp; 465 &amp; 25, but it just didn't work.</p>
  <p>I want to cat some firewall log file to find which port wouldn't be aborted. And I cat the file /usr/sbin/firewalld author is you, and firewall import config,config set the log file location. So, how to locate the log file's location?</p>
