创建ssh密钥后，ubuntu vps上的MongoDB / Mongod‘连接被拒绝’错误

Question

我今天为我的vps创建了一个ssh密钥。当我重新启动vps并尝试运行'mongo‘或’mongo‘时，我得到了以下错误：

对于mongo：

System-info: Ubuntu 19.04

我可以做些什么来修复这个问题，让它在不丢失我的数据的情况下再次工作？

我通过再次检查安装步骤解决了这个问题：https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

这以某种方式解决了它，现在它起作用了
