我正在尝试在运行Nginx的Ubuntu 16服务器上安装第二个WP站点。根据我的服务器结果，我已经成功安装了WordPress，但我仍然只得到了Nginx主页。我想这可能是因为组所有者是用户，所以我将web文件上的组所有者更改为www数据：

microurb@vps148370:/var/www/dancortes.press/public_html$ ls -l

-rw-rw-r--  1 microurb www-data  3065 Oct  8 17:07 xmlrpc.php

尽管如此，我只看到了Nginx的主页。我重新启动了几次Nginx。

我检查了访问和错误日志，得到的只是第一个站点上的代码错误。

我查看了nginx访问日志：

73.197.81.232 - - [08/Oct/2017:19:10:55 -0400] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"
73.197.81.232 - - [08/Oct/2017:19:10:56 -0400] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"

错误日志中有一个关于我的第一个站点上的代码的错误：

PHP message: PHP Notice:  Undefined index: success in /var/www/microurb.com/public_html/index.php on line 295" while reading upstream, client: 71.168.149.103, server: microurb.club, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "microurb.club"

2017/10/08 19:10:52 [alert] 23108#23108: aborting

我真的不知道下一步该找什么。为什么我看不到WP站点？

我决定做一个nginx-t，结果是：

microurb@vps148370:/etc/nginx/sites-available$ nginx -t
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
2017/10/08 19:41:25 [warn] 23341#23341: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
2017/10/08 19:41:25 [emerg] 23341#23341: open() "/run/nginx.pid" failed (13: Permission denied)
nginx: configuration file /etc/nginx/nginx.conf test failed

对于正在发生的事情，我现在并没有那么开明。
