nginx -V 只能查看自己编译的时候带的参数，nginx本身默认安装的模块看不到。刚好最近接手的一个项目就这种，所谓的交接资料，很多情况都需要自己去摸索。

nginx -V 查看

# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.14.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --with-http_gzip_static_module --with-http_ssl_module

源码文件查看

当时安装时候的源码包仍是保留着，所以我们可查看nginx源码包里auto文件夹下的option文件,带YES的表示默认安装时候自带的模块 。
