/etc/nginx/koi-utf
/etc/nginx/koi-win
/etc/nginx/modules
/etc/nginx/scgi_params
/etc/nginx/uwsgi_params
/etc/nginx/win-utf
/etc/sysconfig/nginx systemctl 管理 nginx的使用的文件
/usr/lib/systemd/system/nginx.service systemctl 管理nginx（开 关 重启 reload） 配置文件
/usr/sbin/nginx nginx命令
/usr/sbin/nginx-debug

/usr/share/nginx/html/50x.html
/usr/share/nginx/html/index.html
/var/cache/nginx
/var/log/nginx nginx日志 access.log 访问日志

root 8425 7482 0 10:51 pts/0 00:00:00 grep --color=auto nginx
1.7检查nginx配置语法：
[root@web01 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
1.8配置hosts解析：
配置www.oldboy.com 的hosts解析
[root@web01 /etc/nginx]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.1.7 www.oldboy.com 配置www.oldboy.com 的hosts解析
检查解析是否成功
[root@web01 /etc/nginx]# ping www.oldboy.com
