我正在使用Digital Ocean，并重新启动了我的VPS，现在我的应用程序无法启动。
起初它说它失去了与我的数据库的连接，现在它只是一个白色屏幕。我不知道该怎么办。
这是消息：
Unable to connect to MongoDB: Failed to connect to: localhost:27017: Remote server has closed the connection
该站点是Codeigniter。

如果我运行mongod，那么我会得到这个（不是说我需要运行这个）：

var $sessionArray = arsray();
没有什么比一个好的arsray更能毁了你的一天了！
