nginx调优操作之nginx隐藏其版本号

1.nginx下载

　　下载网址:nginx.org

2.解压nginx

[root@iZwz9cl4i8oy1reej7o8pmZ soft]# ls
nginx-.tar.gz
[root@iZwz9cl4i8oy1reej7o8pmZ soft]# .tar.gz 

3.修改源码

[root@iZwz9cl4i8oy1reej7o8pmZ soft]# ls
nginx-  nginx-.tar.gz#进入nginx源码包
[root@iZwz9cl4i8oy1reej7o8pmZ soft]# cd nginx-
[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src
[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# 

　　修改nginx.h文件

[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src
[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# cd src/core/
[root@iZwz9cl4i8oy1reej7o8pmZ core]# vim nginx.h
[root@iZwz9cl4i8oy1reej7o8pmZ core]# 

　　修改后如下:

   #ifndef _NGINX_H_INCLUDED_
   #define _NGINX_H_INCLUDED_

  #define nginx_version      1010003　　　　　　
  #define NGINX_VERSION      "0.0.1"　　　　　　　　　　　　#NGINX对外显示的版本号
  #define NGINX_VER          "LiWang/" NGINX_VERSION　　 #NGINX对外显示的服务器名

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

  #define NGINX_VAR          "NGINX"
  #define NGX_OLDPID_EXT     ".oldbin"

  #endif /* _NGINX_H_INCLUDED_ */

　　修改ngx_http_special_response.c内容

#进入src/http文件夹下
[root@iZwz9cl4i8oy1reej7o8pmZ http]# pwd
/root/soft/nginx-/src/http#利用vim编辑ngx_http_special_response.c文件
[root@iZwz9cl4i8oy1reej7o8pmZ http]# vim ngx_http_special_response.c 

 #修改结果如下 static ngx_int_t ngx_http_send_error_page(ngx_http_request_t *r,
      ngx_http_err_page_t *err_page);
  static ngx_int_t ngx_http_send_special_response(ngx_http_request_t *r,
      ngx_http_core_loc_conf_t *clcf, ngx_uint_t err);
  static ngx_int_t ngx_http_send_refresh(ngx_http_request_t *r);

  static u_char ngx_http_error_full_tail[] =
  "<hr><center>" NGINX_VER "Server:LiWang blog:www.cnblogs.com/wang-li</center>" CRLF
  "</body>" CRLF
  "</html>" CRLF
  ;

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

　　编辑vim ngx_http_header_filter_module.c 文件

[root@iZwz9cl4i8oy1reej7o8pmZ http]# pwd
/root/soft/nginx-/src/http
[root@iZwz9cl4i8oy1reej7o8pmZ http]# vim ngx_http_header_filter_module.c 

　　修改结果如下

  static char ngx_http_server_string[] = "Server: LiWang" CRLF;
  static char ngx_http_server_full_string[] = "http://www.cnblogs.com/wang-li" NGINX_VER CRLF;

  static ngx_str_t ngx_http_status_lines[] = {

      ngx_string("200 OK"),
      ngx_string("201 Created"),
      ngx_string("202 Accepted"),
      ngx_null_string,  /* "203 Non-Authoritative Information" */
      ngx_string("204 No Content"),
      ngx_null_string,  /* "205 Reset Content" */
      ngx_string("206 Partial Content"),

      /* ngx_null_string, */  /* "207 Multi-Status" */

  #define NGX_HTTP_LAST_2XX  207
  #define NGX_HTTP_OFF_3XX   (NGX_HTTP_LAST_2XX - 200)

4.开始进行源码编译

　　安装必要的插件

[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# yum install -y pcre pcre-devel zlib zlib-devel

　　添加nginx用户

[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# useradd nginx -s /sbin/nologin
[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]#  /etc/passwd
nginx:x::::/home/nginx:/sbin/nologin

　　开始进行编译

[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# ./configure --prefix=/usr/local/nginx-1.10 --user=nginx --group=nginx

　　出现如下信息则为制作ok

Configuration summary

  + OpenSSL library is not used
  + using builtin md5 code
  + sha1 library is not found

  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

　　开始make and make install

[root@iZwz9cl4i8oy1reej7o8pmZ nginx-]# make && make install

5.开始配置

　　配置参照网址:

　　http://www.cnblogs.com/wang-li/p/6689615.html

　　配置过后进行访问

[root@iZwz9cl4i8oy1reej7o8pmZ conf]# curl -I www.wang-li.top:
