whereis nginx

nginx: /usr/sbin/nginx     /usr/lib64/nginx     /etc/nginx    /usr/share/nginx    /usr/share/man/man8/nginx.8.gz

以下是Nginx的默认路径：

(1) Nginx配置路径：/etc/nginx/

(2) PID目录：/var/run/nginx.pid

(3) 错误日志：/var/log/nginx/error.log

(4) 访问日志：/var/log/nginx/access.log

只需知道Nginx配置路径，其他路径均可在/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf 中查询到。
