当我尝试安装 processmaker stackN220 时出现错误。 由于我不是企业客户，processmaker 的支持团队没有在对讲聊天中回答任何问题！

我的配置是：

#ProcessMaker HTTP Virtual Host

server {

  listen 80;
  listen [::]:80;
  #Change for server DNS name
  server_name processmakernginx.local;
  #The following line must be added Only if phpMyAdmin is configured
  #include /opt/phpMyAdmin/phpMyAdmin.conf;

  root /opt/processmaker/workflow/public_html; #where ProcessMaker is installed

  index index.html index.htm app.php index.php;

  }

  location = /robots.txt  { access_log off; log_not_found off; }

  access_log /var/log/nginx/pm-access.log combined; #enables access logs

    include fastcgi_params;
    fastcgi_param    SCRIPT_FILENAME  /opt/processmaker/workflow/public_html/app.php;
    fastcgi_intercept_errors off;
    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;

    fastcgi_read_timeout 300;

  }

 }


 location ~ /\.ht {
   deny all;
 }

 error_page 404 /404.html;
 error_page 500 502 503 504 /50x.html;
 location = /50x.html {
   root /usr/share/nginx/html;
 }

} 

但出现错误

FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream

。

当调用 URL 时，首先会有一个 html 文件将其重定向到

http://processmakernginx.local/sys/en/neoclassic/login/login

file not found

出现。
