我正在NginX服务器上设置PHPMyAdmin。系统本身可以工作，但是我应该可以修改设置的/setup页面（例如，建立一个新的config.inc.php）是空白的。它没有显示错误，返回200 OK，并且在/var/log/nginx/error. log中没有任何内容。
下面是我在这个服务器块上的nginx配置：

listen [::]:80;

root                /usr/share/phpmyadmin; # path to my pma installation
index               index.php;
charset             utf-8;

server_name         my-host;

location / {
    autoindex       off;
}

location ~ \.php$ {
    try_files       $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass    127.0.0.1:9000;
    fastcgi_index   index.php;
    include         fastcgi_params;
}

location ~ /\. {
    deny            all;
}

location /libraries {
    deny            all;
}

location /setup/lib {
    deny            all;
}

有人知道这里发生了什么吗？
