问题：nginx: [emerg] unknown directive “more_clear_headers” in /usr/local/nginx/conf/nginx.conf:374

新增模块more_clear_headers的处理步骤：

1、查看nginx编译时安装的模块

/usr/local/nginx/sbin/nginx -V

nginx version: nginx/1.10.1

built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)

built with OpenSSL 1.0.1g 7 Apr 2014

TLS SNI support enabled

configure arguments: –user=www –group=www –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –with-http_gzip_static_module –with-pcre=/home/temp/pcre-8.37 –with-zlib=/home/temp/zlib-1.2.8 –with-openssl=/home/temp/openssl-1.0.1g

2、添加新的模块headers-more-nginx-module-0.29

3、备份原有nginx，重新拷贝nginx

另：

1、报错nginx: [emerg] host not found in upstream “test.xxx.com”

in /usr/local/nginx/vhosts/test.xxx.com.conf:12

原因：nginx配置语法上没有错误,是系统无法解析这个域名。

解决方法：

vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 test.xxx.com
