如果Nginx错误日志中有可疑条目，该怎么办

Question

I'm very very new with server stuff and I have just setup a server with nginx 1.11 and php7.

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 7ammart.com

What should I do?? How do I stop it? How will I know where it was running from?

Here is the error log:

2016/09/11 10:19:19 [error] 3315#3315: *1 open() "/usr/share/nginx/html/robots.txt" failed (2: No such file or directory), client: 162.210.196.130, server: localhost, request: "GET /robots.txt HTTP/1.0", host: "7ammart.com"

I can't believe I have just set this up today and there is already a suspicious activty

Answer 1

7ammart.com is the hostname of a server which is running a web crawler . Trying to crawl your website.

Looks like you don't have a robots.txt , please add one. There is a guide here , which explains how to do that.

You can make rules to deny or allow bots.

Place the file at the root from where your html is served.
