在单个 httpd 实例中使用具有 mod 代理的虚拟主机配置多个域

Question

我有一个 apache 实例运行三个域使用基于名称的虚拟主机，每个域都有资源将它们反向代理到应用程序服务器。应用服务器是一个JBoss运行一个自JVM实例(http://x.x.x.x:8080/)

域及其资源是，

www.abc.com
 - alpha
www.def.com
 - beta
www.ghi.com
 - gamma
 - (root URL - no resource)

abd.com 和 def.com 域有一种资源，而 ghi.com 有两种（根 (/) 和 gamma）。

这就是我们为三个不同域设置虚拟主机的方式。 abc.com 域的示例如下，

<VirtualHost *>
ServerName abc.com

            Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/alpha" env=BALANCER_ROUTE_CHANGED
            <Proxy balancer://mycluster1>
                        <LimitExcept POST GET>
                                order Allow,Deny
                                Deny from all
                        </LimitExcept>
                                BalancerMember http://x.x.x.x:8080 route=1 retry=0
                                BalancerMember http://x.x.x.x:8081 route=2 retry=0
                                ProxySet stickysession=ROUTEID
            </Proxy>
        ProxyPass /alpha balancer://mycluster4/alpha
        ProxyPassReverse /alpha balancer://mycluster4/alpha
</VirtualHost>

当我尝试访问这些域时，所有配置都已到位，

www.abc.com/alpha  --> works
www.def.com/beta   --> works

www.ghi.com/gamma  --> works
www.ghi.com/       --> works

因为ghi.com域有一个根映射（/），我可以通过ghi.com访问其他域的资源，如果我删除根映射，跨域资源访问就不起作用了。

www.ghi.com/alpha   --> works
www.ghi.com/beta    --> works

我不想通过ghi.com访问其他域的资源。我无法从 ghi.com 虚拟主机配置中删除根映射。

我们尝试了多种配置，但 none 已经成功。我在这里听起来可能有点非技术性，我深表歉意，但这是我的问题陈述，我正在寻找解决方案。

更新 1：pandurang 提出的修复后的配置文件。

NameVirtualHost *
<VirtualHost *>
ServerName ghi.com

    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/gamma " env=BALANCER_ROUTE_CHANGED
    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/ " env=BALANCER_ROUTE_CHANGED
    <Proxy balancer://mycluster4>
                <LimitExcept POST GET>
                        order Allow,Deny
                        Deny from all
                </LimitExcept>
                        BalancerMember http://x.x.x.x:8080 route=1 retry=0
                        BalancerMember http://x.x.x.x:8081 route=2 retry=0
                        ProxySet stickysession=ROUTEID
    </Proxy>
    ProxyPass /gamma balancer://mycluster4/gamma
    ProxyPassReverse /gamma balancer://mycluster4/gamma
    ProxyPass / balancer://mycluster4/
    ProxyPassReverse / balancer://mycluster4/
    ProxyPass /alpha !
</VirtualHost>

Answer 1

在 www.ghi.com 中创建三个不同的基于名称的 VirtualHost 并禁用上下文（alpha 和 beta）。

<VirtualHost www.abc.com>
ServerName abc.com
Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/alpha" env=BALANCER_ROUTE_CHANGED
<Proxy balancer://mycluster1>
<LimitExcept POST GET>
order Allow,Deny
Deny from all
</LimitExcept>
BalancerMember http://x.x.x.x:8080 route=1 retry=0
BalancerMember http://x.x.x.x:8081 route=2 retry=0
ProxySet stickysession=ROUTEID
</Proxy>
ProxyPass /alpha balancer://mycluster4/alpha
ProxyPassReverse /alpha balancer://mycluster4/alpha
</VirtualHost>

<VirtualHost www.def.com>
ServerName def.com
Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/beta" env=BALANCER_ROUTE_CHANGED
<Proxy balancer://mycluster1>
<LimitExcept POST GET>
order Allow,Deny
Deny from all
</LimitExcept>
BalancerMember http://x.x.x.x:8080 route=1 retry=0
BalancerMember http://x.x.x.x:8081 route=2 retry=0
ProxySet stickysession=ROUTEID
</Proxy>
ProxyPass /beta balancer://mycluster4/beta
ProxyPassReverse /beta balancer://mycluster4/beta
</VirtualHost>

<VirtualHost www.ghi.com>
ServerName ghi.com
Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED
<Proxy balancer://mycluster1>
<LimitExcept POST GET>
order Allow,Deny
Deny from all
</LimitExcept>
BalancerMember http://x.x.x.x:8080 route=1 retry=0
BalancerMember http://x.x.x.x:8081 route=2 retry=0
ProxySet stickysession=ROUTEID
</Proxy>
ProxyPass /alpha !
ProxyPass /beta !
ProxyPass / balancer://mycluster4/
ProxyPassReverse / balancer://mycluster4/
</VirtualHost>

Answer 2

使用下面的顺序进行测试。

ProxyPass /alpha !
ProxyPass /gamma balancer://mycluster4/gamma
ProxyPassReverse /gamma balancer://mycluster4/gamma
ProxyPass / balancer://mycluster4/
ProxyPassReverse / balancer://mycluster4/
