wildfly 9.0独立集群与httpd2.4。和mod_cluster1.3.1

时间：2021-04-19 16:56:49

I want to set up a standalone Wildfly cluster with 2 nodes. For this purpose I set up 2 fedora22 virtual machines. On both nodes I installed Wildfly 9.0.0.Final and run it with standalone-ha.xml configuration file. On first node I also installed httpd 2.4 and mod_cluster 1.3.1. Current setting are listed below. On both machines I disabled firewall and SELinux.

我想要设置一个独立的、带有两个节点的Wildfly集群。为此，我设置了2个fedora22虚拟机。在两个节点上，我安装了Wildfly 9.0.0。最后，以标准的方式运行它。xml配置文件。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。

I start httpd with systemctl start httpd and then i run Wildfly with ./standalone.sh -c standalone-ha.xml. Servers starts without an error and deploy application. I can see my application on both nodes on localhost:8080

我使用systemctl启动httpd启动httpd，然后运行Wildfly。/独立。sh - c standalone-ha.xml。服务器从没有错误和部署应用程序开始。我可以在本地主机上的两个节点上看到我的应用程序:8080。

On 192.168.2.240:6666/mod_cluster_manager i can see following screen:

在192.168.2.240:6666/mod_cluster_manager我可以看到以下屏幕:

wildfly 9.0独立集群与httpd2.4。和mod_cluster1.3.1

When i want to get my app in browser on address http://192.168.2.240/ but i get 503 Service Unavailable when i restart httpd and page 404 - Not found few seconds letter. On http://192.168.2.240:6666/ i get fedora test page. Error log of httpd dont show any error only debug messages.

当我想在http://192.168.2.240/的浏览器上获取我的应用程序时，当我重新启动httpd和404页面时，我得到了503服务。在http://192.168.2.240:6666/我得到fedora测试页面。httpd的错误日志不会显示任何错误，只有调试消息。

I think i have problem in configuration where my app gets deployed.

我想我在配置上有问题我的应用程序被部署了。

Problem was on command: ServerAdvertise On I changed it to: ServerAdvertise On IP:6666

问题出在命令上:服务器上的广告我把它改成了:服务器上的IP:6666。

I also delelted whole virtual Host section for port 80 in httpd.conf After that it worked

我还在httpd中删除了端口80的整个虚拟主机部分。在那之后，它起作用了。
