修改nginx返回的默认的server信息

通过修改nginx源码来修改nginx返回的默认的server信息。

1、修改请求响应头中的server信息

修改前的代码和响应头中的server信息：
代码文件路径：nginx-1.21.4\src\http\ngx_http_header_filter_module.c

static u_char ngx_http_server_string[] = "Server: nginx" CRLF;
static u_char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;
static u_char ngx_http_server_build_string[] = "Server: " NGINX_VER_BUILD CRLF;

修改后的代码和响应头中的server信息：

static u_char ngx_http_server_string[] = "Server: parasaga" CRLF;
static u_char ngx_http_server_full_string[] = "Server: parasaga" CRLF;
static u_char ngx_http_server_build_string[] = "Server: " NGINX_VER_BUILD CRLF;

"

;
static u_char ngx_http_error_build_tail[] =
