By modifying the nginx conf file, you can easily customize the HTTP Header.

Nginx uses the ngx_headers_more module to add and delete outbound and inbound Header information. By default, this module is not added to the source code of Nginx. If you want to use related functions, you need to add this module when compiling Nginx. Nginx in my server did not add this module when compiling. Use -V to view the current Nginx compilation parameters:

[root@z-dig ~]# nginx -V
nginx version: www.z-dig.com
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=www --group=www \
--with-http_ssl_module --with-http_stub_status_module
[root@z-dig ~]#
Copy after login

Download the module from the official website:

[root@z-dig ~]# cd /usr/local/src/
[root@z-dig src]# wget 、https://codeload.github.com/openresty/headers-more-nginx-module/zip/master\
 -O ./headers-more-nginx-module-master.zip
[root@z-dig src]# unzip headers-more-nginx-module-master.zip
Copy after login

Before recompiling Nginx, request www. Header information of z-dig.com:

[root@KVM ~]# curl -I www.z-dig.com
HTTP/1.1 200 OK
Server: www.z-dig.com
Date: Sat, 23 Apr 2016 11:25:15 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
X-Powered-By: PHP/5.6.17
Vary: Accept-Encoding, Cookie
Cache-Control: max-age=3, must-revalidate
WP-Super-Cache: Served supercache file from PHP

[root@KVM ~]#
Copy after login

Now recompile Nginx and update smoothly:

[root@z-dig ~]# cd /usr/local/src/nginx
[root@z-dig nginx]# make clean
rm -rf Makefile objs
[root@z-dig nginx]#./configure --prefix=/usr/local/nginx --user=www --group=www \
--with-http_ssl_module --with-http_stub_status_module \
--add-module=/usr/local/src/headers-more-nginx-module-master
[root@z-dig nginx]# make
[root@z-dig nginx]# make install
[root@z-dig nginx]# kill -s USR2 `cat /usr/local/nginx/logs/nginx.pid`
[root@z-dig nginx]# ps -ef|grep nginx
root      2017     1  0 Apr21 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www       2018  2017  0 Apr21 ?        00:00:30 nginx: worker process     
root     21717  2017  0 19:41 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www      21718 21717  0 19:41 ?        00:00:00 nginx: worker process     
root     21856 18312  0 19:45 pts/2    00:00:00 grep nginx
[root@z-dig nginx]# kill -s WINCH `cat /usr/local/nginx/logs/nginx.pid.oldbin`
[root@z-dig nginx]# ps -ef|grep nginx
root      2017     1  0 Apr21 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
root     21717  2017  0 19:41 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www      21718 21717  0 19:41 ?        00:00:00 nginx: worker process     
root     21943 18312  0 19:49 pts/2    00:00:00 grep nginx
[root@z-dig nginx]# kill -s QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
[root@z-dig nginx]# ps -ef|grep nginx
root     21717     1  0 19:41 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www      21718 21717  0 19:41 ?        00:00:00 nginx: worker process     
root     22050 18312  0 19:54 pts/2    00:00:00 grep nginx
[root@z-dig nginx]#
Copy after login

At this point, Nginx has been recompiled and smoothly upgraded successfully.

Add code to the Nginx configuration file to delete the X-Powered-By and WP-Super-Cache in the header returned by the previously requested website:

more_clear_headers 'X-Powered-By';
more_clear_headers 'WP-Super-Cache';
[root@z-dig ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@z-dig ~]# nginx -s reload
Copy after login

Request again to see the effect:

[root@KVM ~]# curl -I www.z-dig.com
HTTP/1.1 200 OK
Server: www.z-dig.com
Date: Sat, 23 Apr 2016 12:03:04 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
Vary: Accept-Encoding, Cookie
Cache-Control: max-age=3, must-revalidate

[root@KVM ~]#
Copy after login

After testing, the header specified information in the request return has been successfully deleted. To learn about other functions of ngx_headers_more, please visit the project official website.
