如何在谷歌云实例上配置 Wildfly 集群

Question

我在谷歌云平台上有问题。 我在VM中尝试POC，它可以正常集群。

但在谷歌云平台。无法在 Wildfly 中加入带有 JGROUP 的集群 我有 2 个实例都在域模式下安装 Centos 7 和 wildfly 10.1.0 final。 我设置如下：https://docs.jboss.org/author/display/WFLY9/WildFly+9+Cluster+Howto

有人有同样的问题吗？

Answer 1

问题是因为 JGroups 默认设置为使用私有接口 (127.0.0.1)。在standalone-ha.xml 你会发现：

<socket-binding name="jgroups-udp" interface="private" port="55200" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45688"/>

将该属性更改为 public 并确保 WildFly 绑定到正确的界面（-b 命令行选项）。
