MongoDB副本集安装程序正在提供-SocketException:无法分配请求的地址

Question

我正在尝试设置MongoDB replica set，在启动服务器时遇到以下错误。

MongoDB版本是4.0.2，我正在尝试安装在Ubuntu 18.04上

我该如何解决？

Answer 1

您需要使用运行mongodb的同一实例/vm的ip或主机名设置绑定ip。

例如：

vm1:bindIp:192.168.10.12上的

• 在vm2:bindIp:192.168.10.13上
• 在vm3:bindIp:192.168.10.14上

但是，请注意，将bindIp设置为127.0.0.1将只绑定到本地环回ip，并且无法从运行在其他vm上的服务器访问。

您需要将它们与适当的内部ip或可解析的主机名绑定。
