JBoss 4.2.2节点开始群集，然后互相怀疑

我有一个网站在现有的Red Hat服务器上运行JBoss 4.2.2。我正在设置第二台服务器，以便拥有集群对（然后将实现负载平衡）。但是，我无法使它们成功地群集

现有服务器通过以下方式启动JBoss：

run.sh -c default -b 0.0.0.0

（我知道“默认”配置不支持开箱即用的群集—我正在使用一个包含群集支持的修改版本。） 当我用同一个命令启动第二个JBoss实例时，它形成了自己的集群，而没有注意到第一个。两者都使用相同的分区名称、多播地址和端口

我尝试了McastReceiverTest和mcastssendertest程序来检查机器是否可以通过多播进行通信；他们可以

然后我注意到的信息是，JGroups不能绑定到所有接口，而是绑定到默认接口；因此，它可能绑定到127.0.0.1，因此无法传递消息。因此，我将实例设置为告诉JGroups使用内部IP：

run.sh -c default -b 0.0.0.0 -Djgroups.bind_addr=10.51.1.131
run.sh -c default -b 0.0.0.0 -Djgroups.bind_addr=10.51.1.141

（.131是现有服务器，.141是新服务器）

这些节点现在相互注意并形成一个集群——首先。但是，在尝试部署.ear时，服务器日志显示：

2010-08-07 22:26:39,321 DEBUG [org.jgroups.protocols.FD] sending are-you-alive msg to 10.51.1.131:46294 (own address=10.51.1.141:47629)

但我不明白为什么第一轮FD检查失败；尽管它最终似乎与另一个节点群集，但当它试图共享实体状态时，最初的失败似乎足以扰乱部署，从而阻止它以有用的方式实际工作

如果有人能说明这一点，我将非常感激

我认为，在您继续使用JBoss 4.2.3（最终可能是一个好地方）或构建新配置（我同意@skaffman关于修剪比添加更容易的观点）之前，您可能需要尝试以下方法：

10.51.1.131：

run.sh-c default-b 10.51.1.131-Djgroups.bind_addr=10.51.1.131

在10.51.1.141上：

run.sh-c默认值-b 10.51.1.141-Djgroups.bind_addr=10.51.1.141

---

根据我能找到的所有文档，

-b

参数是服务器实例绑定地址，让它们不同可能会给JGroups带来严重的精神分裂。我有一个四服务器集群环境成功运行了三年多，这是RH/JBoss推荐配置的一部分（我们有一份支持合同，并得到了Bela Ban的帮助）。

这确实是一个令人困惑的问题。我假设您使用JBoss 4.2.2&一种定制的服务器配置是有原因的，但是您能用JBoss 4.2.3（其中包括一些jgroups更改）和/或“all”配置重新创建它吗？定制的配置是为了在“default”和“all”之间折衷，即没有我们不使用的位的“all”。要尝试其他配置需要做一些工作（因为我不能随意处理现有节点，因此需要添加第三个），但我会看看是否可以尝试这些配置——感谢您的建议。我强烈建议减少

所有

配置，而不是在

默认

配置中添加内容。很容易错过一些看起来没有用的关键组件。
