Mule集群部署问题

Question

我正在尝试在Mulesoft中实现集群。我的目的是将应用程序部署到应用程序服务器集群。我在绑定到集群的两台物理机上各安装了一台Mule服务器。然后，我创建了一个Mule应用程序，它侦听HTTP端点以触发邮件。我在通过MMC将应用程序部署到创建的Mule集群时遇到问题。

Click to see the cluster of servers将应用程序部署到集群中的一台服务器，并且在部署到另一台服务器时存在问题。我得到的错误是：

是否需要对集群部署进行任何特定的配置更改？有谁能帮帮我。

此外，我们也非常欢迎与BAM相关的建议

Answer 1

正如日志所述，您的HTTP侦听器正在尝试使用已使用的端口

绑定由: java.net.BindException:地址已在使用中：

引起

使用操作系统工具找出哪个进程正在使用该端口。

Answer 2

当您通过Mule Management Console部署您的应用程序以构建框架时，cluster.You应该在您的场景中将HTTP inbound端点的应用程序端点公开为"localhost:portnumber".Here，因为两个服务器都在同一设备中。

单机中的两个MULE服务器实例

出现绑定异常时，serverA的端点将被描述为machineAIP:8080，serverB也将被描述为绑定

在两台不同的机器上运行两个服务器实例

在机器IP的帮助下，serverA的端点将被描述为machineAIP:8080，而serverB也将被描述为machineIPB:8080.Here。

因此，使用两个不同的servers.If总是很好的，使用同一台机器创建两个mule服务器实例会导致与暴露相同的endpoints.We相关的问题。需要使用两个不同的机器来增强高availability.It还可以确保机器的崩溃不会影响集群服务器的功能。

使用两台不同的机器部署应用程序(每台机器都有一个mule服务器实例)，并且您在入站端点中指定的端口号也没有使用。

如果我的回答能给你一个解决方案。快乐编码:)

Answer 3

基于这个例外-

原因: java.net.BindException:地址已在使用: bind

这可能是因为两个原因-

通过连接器用于mule应用程序的端口已在服务器级别使用，因此请尝试更改该端口，并确保该端口未被使用。HTTP

1. 如果您在集群环境中使用MMC部署mule应用程序，那么您必须将您的

连接器配置为localhost或0.0.0.0端口，以便在集群下的服务器/节点中部署时它将使用localhost ref。

请注意，当您使用localhost或0.0.0.0时，应用程序将部署在节点中，您的负载均衡器将指向节点地址(主机dns)，然后它将使用您在http连接器中提到的端口重新定向对两个节点的调用。

请尝试让我知道它是否解决了问题。
