1. 查看nginx的PID,以常用的80端口为例:

netstat -anop | grep 0.0.0.0:80

  1. 通过相应的进程ID(比如:4562)查询当前运行的nginx路径:

ll /proc/4562/exe

  1. 获取到nginx的执行路径后,使用-t参数即可获取该进程对应的配置文件路径,如:

/usr/local/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
