如何使用Nginx定义Header头信息

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 -Vnginx version: www.z-dig.combuilt by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)built with OpenSSL 1.0.1e-fips 11 Feb 2013TLS SNI support enabledconfigure 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.comHTTP/1.1 200 OKServer: www.z-dig.comDate: Sat, 23 Apr 2016 11:25:15 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.17Vary: Accept-Encoding, CookieCache-Control: max-age=3, must-revalidateWP-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 cleanrm -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 nginxroot      2017     1  0 Apr21 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginxwww       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/nginxwww      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 nginxroot      2017     1  0 Apr21 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginxroot     21717  2017  0 19:41 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginxwww      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 nginxroot     21717     1  0 19:41 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginxwww      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]#

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 -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: 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.comHTTP/1.1 200 OKServer: www.z-dig.comDate: Sat, 23 Apr 2016 12:03:04 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveVary: Accept-Encoding, CookieCache-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。
