Nginx pre-compilation optimization [root@linuxprobe ~] # wget http://nginx.org/download/nginx-1.10.1.tar.gz[root@linuxprobe ~] # tar xvf nginx-1.10.1.tar.gz-C / usr/local/src/ [root@linuxprobe ~] # cd / usr/local/src/nginx-1.10.1/ pre-compilation optimization is mainly used to modify program names, etc. For example: [root@linuxprobe nginx-1.10.1] # curl-I http://www.baidu.com. Server: bfe/1.0.8.14... [root@linuxprobe nginx-1.10.1] # curl-I http://www.sina.com.cn. Server: nginx... [root@linuxprobe nginx-1.10.1] # curl-I https://www.linuxprobe.comHTTP/1.1 200 OKServer: nginx/1.10.1 # our goal is to change the name of nginx Content-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.29Set-Cookie: PHPSESSID=smm0i6u4f9v7bj0gove79ja1g7 Path=/Cache-Control: no-cacheDate: Mon, 07 Seq 2016 06:09:11 GMT [root@linuxprobe nginx-1.10.1] # vim src/core/nginx.h to change the name and version number of the source code hiding software

# define NGINX_VERSION "nginx_stable" # this line modifies the version number you want

# define NGINX_VER "linuxprobe/" NGINX_VERSION # this line modifies the name of the software you want to change

[root@linuxprobe nginx-1.10.1] # vim + 49 src/http/ngx_http_header_filter_module.c modifies the connection field in the HTTP header to prevent specific version numbers from being echoed

Expansion: general http header domain

The common header domain contains the header domain supported by both request and response messages, and the common header domain includes Cache-Control, Connection, Date, Pragma, Transfer-Encoding, Upgrade, and Via. The extension of the universal header domain requires that both sides of the communication support this extension, and if there is an unsupported universal header domain, it will generally be treated as an entity header domain. That is to say, some devices, or software, can get connection, but some can't, so you have to hide it thoroughly!

[root@linuxprobe nginx-1.10.1] # vim + 29 src/http/ngx_http_special_response.c defines the return of http error codes

Sometimes when there is an error in our page program, Nginx will return the corresponding error code on our behalf. When it is echoed, it will be returned with nginx and version number, and we will hide it.
