查看nginx实际调用的配置文件
1.查看nginx路径
ps aux|grep nginx
root 0.0 0.0 ?? S :43上午 :00.08 nginx: worker process
root 0.0 0.0 ?? S :43上午 :00.02 nginx: master process /usr/local/opt/nginx/bin/nginx -g daemon off;
root 0.0 0.0 s000 S+ :01下午 :00.00 grep nginx
nginx的路径为：/usr/local/opt/nginx/bin/nginx
2.查看nginx配置文件路径
使用nginx的 -t 参数进行配置检查，即可知道实际调用的配置文件路径及是否调用有效。
/usr/local/opt/nginx/bin/nginx -t
nginx: the configuration file /usr/local/etc/nginx/nginx.conf syntax is ok
nginx: configuration file /usr/local/etc/nginx/nginx.conf test is successful
测试可知，nginx的配置文件路径为：/usr/local/etc/nginx/nginx.conf 且调用有效。
