static char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;
To: 
static char ngx_http_server_string[] = "Server: Secure Web Server" CRLF;
static char ngx_http_server_full_string[] = "Server: Secure Web Server" CRLF;

11.Run the commands bellow to compile the Nginx environment:
./configure --with-http_ssl_module --without-http_autoindex_module --without-http_ssi_module
make

make install

12.Remove the Nginx source files:
rm -rf /tmp/nginx-0.7.65
rm -f /tmp/nginx-0.7.65.tar.gz

13.Remove Default Content
rm -rf /usr/local/nginx/html

14.Updating Ownership and Permissions on Nginx folders:
chown -R root:root /usr/local/nginx
chmod 750 /usr/local/nginx/sbin/nginx
chmod -R 640 /usr/local/nginx/conf
chmod -R 770 /usr/local/nginx/logs

15.Create folder for the web content:
mkdir -p /www
 

16.Updating Ownership and Permissions on the web content folder:
chown -R root /www
chmod -R 775 /www
 

17.Edit using VI the file /usr/local/nginx/conf/nginx.conf and change the following settings:
From:
#user nobody;To:
user nginx nginx;
From:
#error_log logs/error.log notice;To:
error_log logs/error.log notice;

From:
server_name localhost;To:
server_name Server_FQDN;

From:
root html;To:
root /www;
 

18.Add the following sections to the end of the /usr/local/nginx/conf/nginx.conf file:
server_tokens off;
client_body_buffer_size 1K;
client_header_buffer_size 1k;
client_max_body_size 1k;
large_client_header_buffers 2 1k;
client_body_timeout 10;
client_header_timeout 10;
send_timeout 10;

19.Create using VI, the file /etc/init.d/nginx with the following content:
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
