apache2 - 域模式下的 wildfly 10 + ubuntu 上的 apache2 + mod_cluster

Question

我正在尝试让以下设置工作:

操作系统:Ubuntu 14.04.3 LTSApache2:Apache/2.4.7 (Ubuntu)mod_cluster 1.3.1wildfly:wildfly-10.0.0.CR2 域模式(主服务器组中的服务器一和同一 ubuntu 服务器上其他服务器组中的服务器二)测试部署:cluster-demo

2 周后，我的 apache 和 mod_cluster 正常工作，但 wildfly 没有按预期工作。

我的 apache 配置:

启用站点/wildfly.conf

Listen 80

<VirtualHost *:80>
    ServerAdmin info@domain.de
    ServerName myserver.com
    ServerAlias www.myserver.com

    ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On
    ProxyPassReverse / balancer://mycluster
    ProxyPreserveHost On

    <Location />
        Order deny,allow
        Allow from All
    </Location>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

启用站点/000-default.conf

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ProxyPass / ajp://host:8009/
    ProxyPassReverse / ajp://host:8009/

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

mods-enabled/mod_cluster.conf

CreateBalancers 1

<IfModule manager_module>
    Listen host:10001

      ManagerBalancerName myclustern

    <VirtualHost host:10001>
        KeepAliveTimeout 300
        MaxKeepAliveRequests 0
        AdvertiseFrequency 5
        ServerAdvertise On http://host:10001
        EnableMCPMReceive
        AdvertiseGroup 224.0.1.105:23364

        <Location />
          Order deny,allow
          Deny from all
          Allow from all
          Require all granted
        </Location>

        <Location /mod_cluster-manager>
           SetHandler mod_cluster-manager
           Order deny,allow
           Deny from all
           Allow from all
        </Location>
    </VirtualHost>
</IfModule>

mods-enabled/mod_cluster.load

LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so

LoadModule proxy_cluster_module /usr/lib/apache2/modules/mod_proxy_cluster.so
LoadModule advertise_module /usr/lib/apache2/modules/mod_advertise.so

mod_cluster-manager 可用，cluster-demo 的演示页面也可用。但是 apache 错误日志显示以下错误:

当我停止服务器一从主服务器组服务器二说，

(Incoming-2,ee,master:server-two) ISPN000094:接收到 channel 网络的新集群 View :[master:server-two|12] (1) [master:server-two]

但在浏览器中我得到的不是集群演示页面:

Service unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

我的 wildfly domain.xml 配置是服务器的标准配置这两个变化:

    <socket-binding-groups>
    <socket-binding-group name="full-ha-sockets" default-interface="public">
        ...
        <outbound-socket-binding name="mc-prox1">
            <remote-destination host="host" port="10001"/>
        </outbound-socket-binding>
    </socket-binding-group>
</socket-binding-groups>

和

<subsystem xmlns="urn:jboss:domain:modcluster:2.0">
    <mod-cluster-config advertise-socket="modcluster" proxies="mc-prox1" sticky-session="true" sticky-session-remove="false" sticky-session-force="false" connector="ajp">
        <dynamic-load-provider>
            <load-metric type="cpu"/>
        </dynamic-load-provider>
    </mod-cluster-config>
</subsystem>

apache 需要 000-default.conf 吗？如果我删除 proxypass 和 proxypassreverse 注释，我将无法访问演示页面。为什么我需要 wildfly 中的代理注释来运行 apache？广告模块有问题吗？

希望有人能帮助我。

当 mod 集群无法 ping 端口 27233 时，我来这里寻找解决方案。在前几周，我试图首先使用 httpd 2.4 设置 wildflys 集群。和 mod cluster 1.3.1 由于它不起作用，我尝试使用 httpd 2.2 and modcluster 1.2.6 .它对我有用。这很重要，所以我知道我有正确的配置。现在我回来了，尝试使用 modcluster 1.3.1 进行设置，但我相信那个端口有问题。该端口甚至没有打开，因此肯定无法 ping 通它。

我认为新的 mod_cluster 中有一些错误。尝试使用旧组件效果很好。
