推荐答案

默认情况下，它应绑定到所有本地地址。因此，假设您的防火墙没有网络层问题，我认为可以检查的唯一ES设置是 network.bind_host 并确保未设置或设置为 0.0.0.0 或 :: 0 或网络的正确IP地址。

By default it should bind to all local addresses. So, assuming you don't have a network layer issue with firewalls, the only ES setting I can think to check is network.bind_host and make sure it is either not set or is set to 0.0.0.0 or ::0 or to the correct IP address for your network.

更新：根据ES 2.3中的注释，您应该设置 network.host 。

Update: per comments in ES 2.3 you should set network.host instead.
