自编译Nginx伪装Server版本信息

Nginx (“engine x”) 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的，第一个公开版本0.1.0发布于2004年10月4日。其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。本篇文章徐叔介绍如何伪装你的Nginx让脚本小子摸不着头脑。:)

一、前期准备

1.Centos7环境。

2.Nginx安装包建议下载稳定版（Stable version），本篇以1.10.2为例子。

3.确认系统中是否已安装gcc、openssl-devel、pcre-devel、zlib-devel。

yum -y install gcc openssl-devel pcre-devel zlib-devel

二、修改相关变量

1.目标文件路径src/core/nginx.h修改后如下：

/*
 * Copyright (C) Igor Sysoev
 * Copyright (C) Nginx, Inc.
 */


#ifndef _NGINX_H_INCLUDED_
#define _NGINX_H_INCLUDED_


#define nginx_version      1010002
#define NGINX_VERSION      "1.10.2"
#define NGINX_VER          "apple/" NGINX_VERSION

#ifdef NGX_BUILD
#define NGINX_VER_BUILD    NGINX_VER " (" NGX_BUILD ")"
#else
#define NGINX_VER_BUILD    NGINX_VER
#endif

#define NGINX_VAR          "APPLE"
#define NGX_OLDPID_EXT     ".oldbin"


#endif /* _NGINX_H_INCLUDED_ */

2.目标文件路径src/http/ngx_http_header_filter_module.c大概位置49-50行，修改后如下：

static char ngx_http_server_string[] = "Server: apple" CRLF;
static char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;

3.目标文件路径src/http/ngx_http_special_response.c大概位置28-32行，修改后如下：

static u_char ngx_http_error_tail[] =
"<hr><center>" NGINX_VER "</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

三、编译安装

1.编译命令：

./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --with-ipv6

2.编译完成后如下代码：

Configuration summary
  + using threads
  + using system PCRE library
  + using system OpenSSL library
  + md5: using OpenSSL library
  + sha1: using OpenSSL library
  + using system zlib library

  nginx path prefix: "/etc/nginx"
  nginx binary file: "/usr/sbin/nginx"
  nginx modules path: "/etc/nginx/modules"
  nginx configuration prefix: "/etc/nginx"
  nginx configuration file: "/etc/nginx/nginx.conf"
  nginx pid file: "/var/run/nginx.pid"
  nginx error log file: "/var/log/nginx/error.log"
  nginx http access log file: "/var/log/nginx/access.log"
  nginx http client request body temporary files: "/var/cache/nginx/client_temp"
  nginx http proxy temporary files: "/var/cache/nginx/proxy_temp"
  nginx http fastcgi temporary files: "/var/cache/nginx/fastcgi_temp"
  nginx http uwsgi temporary files: "/var/cache/nginx/uwsgi_temp"
  nginx http scgi temporary files: "/var/cache/nginx/scgi_temp"

3.安装命令：

make install
