Node.js 节点未连接到托管mongodb服务器，第一次连接时未能连接到服务器

我有一个Godaddy托管的网站，我正试图让节点连接到我的Godaddy Mongo服务器。如果我使用完全相同的文件在mac os localhost上运行，我可以让它连接到托管服务器。 我正在我的托管站点上运行一个MEAN stack应用程序，mongo服务器正在使用bitnami。 当我SSH到我的godaddy托管站点，然后运行

node server/server.js

时，会出现以下错误：

toldhandyman@a2plcpnl0843 [~/public_html]$ node server/server.js

events.js:163
  throw er; // Unhandled 'error' event

当我在我的托管站点上使用相同的代码时，它给了我以前的错误

MongoError:无法连接到上的服务器[45.40.179.118:27017]
第一次连接[MongoError:connect Econrefuse45.40.179.118:27017]

。 Godaddy服务器正在使用Bitnami mongodb。我试着浏览他们的文档、godaddy支持和许多其他地方。我试着把端口改成27018。在

bitnami@told-杂工：/opt/bitnami/mongodb/mongodb.conf

在处理行时也没有帮助：

#bind_ip = 127.0.0.1
#bind_ip = 0.0.0.0
port = 27017

我还尝试为数据库添加不同的用户，并使用这些凭据登录，但这只在localhost上起作用。我还尝试过几次停止服务器并重新启动它。 我已经确保它确实到达dbpath=/data/db

我注意到的另一个问题是，当我使用SSH连接到服务器时，让

mongod

在服务器中工作。如果不运行

mongod

，我的本地主机就可以与托管服务器连接并正常工作。当我在bitnami mongo服务器中运行该行时，它显示：

bitnami@told-handyman:~$ mongod

当我运行

mongod--port 27018

时，它会工作，并在本地主机上正常运行。我认为让“mongod”正常工作可能是让我的托管站点连接到我的mongo服务器的问题的一部分

总结一下我的问题，我有一个Godaddy托管的网站无法连接到我的Godaddy cloud Mongo服务器。我可以SSh连接到这两个节点，并在托管站点上安装节点。在服务器上运行

mongod

也会抛出一个错误，但不知何故，服务器仍然使用我的本地主机运行，甚至没有输入该命令

有人知道如何解决通过节点将server.js文件连接到mongo服务器的问题吗？我是否遗漏了将托管网站连接到托管服务器（与本地运行两者不同）的任何内容

这是我的第一个问题。感谢您的时间和帮助。

欢迎来到SO！你的帖子很长。很好，你已经非常详细了，但我觉得你可以对你的问题和问题更简洁一点。关于你的问题，我猜是防火墙的问题。因此，请验证客户端和服务器之间的端口是否打开。请尝试通过Godaddy防火墙打开端口27017。

#bind_ip = 127.0.0.1
#bind_ip = 0.0.0.0
port = 27017
