我一直在为 mongo bind IP 而苦苦挣扎，我觉得现在是时候寻求帮助了。我正在使用 hostonly 网络192.168.56.0/24。我有 4 个盒子。3 个盒子用于 mongo 192.168.56.111,192.168.56.112,192.168.56.113。一个盒子用于应用程序192.168.56.114。
因此对于 mongo 绑定参数是：bind_ip =127.0.0.1,192.168.56.114,192.168.56.113,192.168.56.112,192.168.56.111,10.0.2.1
2015-08-22T12:35:44.547+0000 E NETWORK [initandlisten] listen(): bind() failed errno:99 Cannot assign requested address for socket: 192.168.56.114:27017

我真的不明白其他 IP 有什么问题。除了环回、自己的 IP 和 0.0.0.0/0 之外，其他所有 IP 都无法启动 mongodb。
答案1
指令bind_ip用于指定 IP 地址在同一个系统上MongoDB 监听连接，不是从中接收连接的 IP 地址。
设置此选项可配置 mongod 或 mongos 进程以绑定到此地址并侦听来自此地址上的应用程序的连接。您可以将 mongod 或 mongos 实例连接到任何接口；但是，如果您将该进程连接到可公开访问的接口，请实施适当的身份验证或防火墙限制以保护数据库的完整性。
因此它应该不存在（推荐），或者包含 127.0.0.1 以仅接受本地连接，或者本地网络接口的 IP 地址。
如果您想限制哪些 IP 地址可以连接到 MongoDB，则需要使用防火墙。
