理解Nginx错误日志

我有如下 Nginx 错误日志文件：

2016/12/16 14:24:45 [error] 2758#0: *506 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 109.61.223.87, server: www.mydomain.fr, request: "GET /download/50/MSMxOz0jM3owLS4rZnJxLAcYExcdCQkdBRMHRQIMGhoCEB4fDQUaEhkKDwkZUwwKr+Xj9+Xa4eL81vrq/uzj/K/3+/x5qulrqiorq+prquWB2bz5A/kbz_ii_v41.exe?sign=global-rus_treid_2?static?cr=60c1ec2384?signtool=osslsigncode-2?rnd=trnt HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "dlc.certainlesson.ru"

是什么意思host: "dlc.certainlesson.ru"？

或者错误日志如下：

2016/12/16 15:50:45 [error] 2743#0: *85931 FastCGI sent in stderr: "PHP message: PHP Warning: require(/home/ubuntu/myapp/releases/20161216145901/vendor/composer/../guzzle/guzzle/src/Guzzle/Common/Exception/InvalidArgumentException.php): failed to open stream: No such file or directory in /home/ubuntu/myapp/releases/20161216145901/app/bootstrap.php.cache on line 2850

是否有人能在我不知情的情况下在我的服务器上运行代码？

提前感谢您的解释。

答案1

这HTTP GET是对指定资源的数据请求，在您的情况下，此资源是dlc.certainlesson.ru。

在 15:50:45 日志中，文件一体式检查器_破解_v3_8.exe正在HTTP GET使用请求

https://dlc.magic-terrify.ru/download/ad/zNzM2NjE1pndwsPIg5WUz97Yz6eoramnvavpvaejv6mpqaqkoKe6saG6rvarr/S4vKq+v4aHl7uVh5WJhJnUioSCioPMwMXFx8PHzMrLzQdmkBM/all-in-one_checker_crack_v3_8.exe

返回没有这样的文件或目录

希望这会有所帮助。
