nginx的模块是需要重新编译nginx，而不是像apache一样配置文件引用.so
这里以安装第三方ngx_http_google_filter_module模块为例
- 下载第三方扩展模块ngx_http_google_filter_module
# cd /data/software/
# git clone https://github.com/cuber/ngx_http_google_filter_module- 查看nginx编译安装时安装了哪些模块
# nginx -V
nginx version: nginx/1.8.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=/data/software/ngx_http_substitutions_filter_module可以看出编译安装使用了--prefix=/usr/local/nginx --with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=/data/software/ngx_http_substitutions_filter_module这些参数。--add-module=/data/software/ngx_http_substitutions_filter_module是之前编译添加ngx_http_substitutions_filter_module模块时添加
- 加入需要安装的模块，重新编译，如这里添加–add-module=/data/software/ngx_http_google_filter_module
# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=/data/software/ngx_http_substitutions_filter_module --add-module=/data/software/ngx_http_google_filter_module
# make //千万不要make install，不然就真的覆盖了- 替换nginx二进制文件:(把nginx停止)
# cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
# cp ./objs/nginx /usr/local/nginx/sbin/如果是内置的模块，在第三步骤的时候，直接--with-相关的模块即可，剩下的步骤依旧
