What to do if there are suspicious entries in nginx error log
<p>I'm very very new with server stuff and I have just setup a server with nginx 1.11 and php7.</p>

<p>While I was still configuring my project paths, I often check with the nginx error logs. I noticed there are from suspicious host listed there. For sure I don't own any <strong>7ammart.com</strong></p>

<p>What should I do?? How do I stop it?
How will I know where it was running from?</p>

<p>Here is the error log:</p>
