我想建立一个具有 2 个节点的独立 Wildfly 集群。为此,我设置了 2 个 fedora22 虚拟机。在两个节点上,我都安装了 Wildfly 9.0.0.Final 并使用standalone-ha.xml
配置文件运行它。在第一个节点上,我还安装了 httpd 2.4 和 mod_cluster 1.3.1。当前设置如下所示。在两台机器上,我都禁用了防火墙和 SELinux。

我用 httpd 开始systemctl start httpd
,然后用./standalone.sh -c standalone-ha.xml
. 服务器启动没有错误并部署应用程序。我可以在 localhost:8080 的两个节点上看到我的应用程序
在 192.168.2.240:6666/mod_cluster_manager 我可以看到以下屏幕:
当我想在地址http://192.168.2.240/上的浏览器中获取我的应用程序时,但是当我重新启动 httpd 和页面 404 时我得到 503 Service Unavailable - 找不到几秒钟的信。在http://192.168.2.240:6666/我得到 fedora 测试页。httpd 的错误日志不显示任何错误,仅显示调试消息。
我认为我在部署我的应用程序的配置方面存在问题。
