Nginx Simple optimization

1. Reduce nginx compiled file size (reduce file size of Nginx)

The default nginx compilation option is in debug mode (-G) (debug mode inserts a lot of trace and assert), and a nginx has several megabytes after compiling. Remove Nginx debug mode compilation, after compiling only hundreds of K
In AUTO/CC/GCC, the last lines are:

# Debug
Cflags= "$CFLAGS-G"

Comment out or delete these lines and recompile.

2. Modify Nginx Header Camouflage Server

1) Modify Nginx.h

#vi nginx-0.7.30/src/core/nginx.h
#define NGINX_VERSION "1.8"
#define Nginx_ver "ltws/" nginx_version
#define NGINX_VAR "NGINX"
#define NGX_OLDPID_EXT ". Oldbin"

2) Modify Nginx_http_header_filter_module

#vi nginx-0.7.30/src/http/ngx_http_header_filter_module.c

will be as follows

static char ngx_http_server_string[] = "Server:nginx" CRLF;

Amended to

static char ngx_http_server_string[] = "Server:ltws" CRLF;

A) Modification of nginx_http_header_filter_module

#vi nginx-0.7.30/src/http/ngx_http_special_response.c

will be as follows:

Static U_char ngx_http_error_full_tail[] =
"<hr><center>" Nginx_ver "</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

Static U_char ngx_http_error_tail[] =
"<hr><center>nginx</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

Modified to:

Static U_char ngx_http_error_full_tail[] =
"<center>" Nginx_ver "</center>" CRLF
"<hr><center>http://www.linuxtone.org</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;

Static U_char ngx_http_error_tail[] =
"<hr><center>LTWS</center>" CRLF
"</body>" CRLF
"</html>" CRLF
;
