1.查看nginx路径
ps aux|grep nginx root 352 0.0 0.0 2468624 924 ?? S 10:43上午 0:00.08 nginx: worker process root 232 0.0 0.0 2459408 532 ?? S 10:43上午 0:00.02 nginx: master process /usr/local/nginx/sbin/nginx -g daemon off; root 2345 0.0 0.0 2432772 640 s000 S+ 1:01下午 0:00.00 grep nginx
nginx的路径为：/usr/local/nginx/sbin/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/nginx/sbin/nginx -t nginx: the configuration file /data/conf/nginx/nginx.conf syntax is ok nginx: configuration file /data/conf/nginx/nginx.conf test is successful
