有时我们不希望有人可以通过一些工具来返回我们服务器的信息，下面我来介绍在nginx中隐藏nginx响应头,修改nginx返回头信息,隐藏php版本号,隐藏服务器信息，同学可参考。

首先隐藏nginx版本信息，只需编辑 nginx.conf 文件
添加一行

server_tokens off;http { include /etc/nginx/mime.types; default_type application/octet-stream; index index.php index.html index.htm; server_tokens off; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf;}

响应头隐藏PHP版本休息,编辑php.ini文件找到expose_php = On , 修改为 expose_php = Off

;;;;;;;;;;;;;;;;;; Miscellaneous ;;;;;;;;;;;;;;;;;;; Decides whether PHP may expose the fact that it is installed on the server; (e.g. by adding its signature to the Web server header). It is no security; threat in any way, but it makes it possible to determine whether you use PHP; on your server or not.; http://www.php.net/manual/en/ini.core.php#ini.expose-phpexpose_php = Off
