Solution to nginx hiding version number and WEB server information

Nginx can not only hide version information, but also support custom web server information

Let’s take a look at the final hidden results first.

How to implement it specifically? It is actually very simple. Please read on.

1 Download the latest stable version from the official website

wget http://nginx.org/download/nginx-1.14.1.tar.gz

2 Unzip

tar -xf nginx-1.14.1.tar.gzcd nginx-1.14.1

3 Modify the C file

(1) vim src/http/ngx_http_header_filter_module.c #Modify line 49

static u_char ngx_http_server_string[] = "Server: Please guess it!" CRLF; #Write your custom server information after Server

(2) vim src/http/ngx_http_special_response.c #Modify line 36
"<hr><center>Please guess it!</center>" CRLF #Write the string again

4 Compilation Configuration

./configure --prefix=/usr/local/nginx

5 Compile and install

make && make install

6 Modify the nginx configuration file and add server_tokens off under the http node

vim /usr/local/nginx/conf/nginx.conf
....
http {
server_tokens off;
..... 

7 Start nginx

/usr/local/nginx/sbin/nginx

8 Testing

[root@node1 nginx-1.14.1]# curl -I http://127.0.0.1 HTTP/1.1 200 OK Server: Please guess it! Date: Wed, 07 Nov 2018 19:15:43 GMT
  ......

Browser access test

illustrate:

(1) If you only want to hide the version number and do not want to customize the server information, you do not need to perform step 3.

(2) If you want to customize the string while upgrading nginx, there is no problem. You can modify the C file first --> ./configure --> make
