通过Nginx定义Header头信息

2017-01-12 10:05:01来源:oschina作者:linux小陶人点击

Nginx 使用 ngx_headers_more 模块来增加、删除出站、入站的 Header 信息。默认该模块没有加入到 Nginx 的源码中,要想使用相关功能需要在编译 Nginx 时加入该模块。本人服务器中的 Nginx 在编译时没有加入该模块,使用 -V 查看当前 Nginx 的编译参数:


[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 ~]#

从官网下载模块:


[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

重新编译 Nginx 前,请求 www.z-dig.com 的 Header 信息:


[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 ~]#

现在重新编译 Nginx ,平滑更新:


[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
root2017 10 Apr21 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www201820170 Apr21 ? 00:00:30 nginx: worker process
root 2171720170 19:41 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www21718 217170 19:41 ? 00:00:00 nginx: worker process
root 21856 183120 19:45 pts/200:00:00 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
root2017 10 Apr21 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
root 2171720170 19:41 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www21718 217170 19:41 ? 00:00:00 nginx: worker process
root 21943 183120 19:49 pts/200:00:00 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 10 19:41 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
www21718 217170 19:41 ? 00:00:00 nginx: worker process
root 22050 183120 19:54 pts/200:00:00 grep nginx
[root@z-dig nginx]#

到此 Nginx 已重新编译并平滑升级成功。


在 Nginx 的配置文件中加入代码,将之前请求网站返回 Header 中的 X-Powered-By 和 WP-Super-Cache 删除:


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

再次请求查看效果:


[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 ~]#

经测试已成功将请求返回中的 Header 指定信息删除。想了解 ngx_headers_more 的其他功能请访问项目官网。
