Apache HTTPD 模块代理多个虚拟主机的负载均衡和 URL 重定向

Question

场景：
操作系统：CentOS
Web服务器：Apache http 版本 2.2.23
两个 WebLogic 服务器集群
两个 Web 服务器
以上内容均在硬件负载均衡器后面。
基本上想要对流量进行 URL 重定向和负载平衡（不修改会话）
当我输入 agent.abconline.com 时，应该被重定向到应用程序服务器 192.168.0.1:7001/agent；staging.abconline.com 应该被重定向到 192.168.0.1;7001/staging。
我可以仅使用 mod_rewrite 完成上述操作，但是在尝试使用 mod_proxy 和负载平衡时，无法将其重定向到所需的 URL。
以下是配置信息。

NameVirtualHost *:80
<VirtualHost *:80>
        ServerName agent.abconline.com
        RewriteEngine On

        <Proxy balancer://agentcluster>
         BalancerMember http://192.168.0.1:7003 route=1 loadfactor=50 retry=60
         BalancerMember http://192.168.0.2:7003 route=1 loadfactor=50 retry=60
        </Proxy>

        # Redirect all non-static requests to agent
        RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
        RewriteRule ^/(.*)$ balancer://agentcluster%{REQUEST_URI} [P,QSA,L]

        ProxyPass /abc-oper balancer://agentcluster/abc-oper
        ProxyPassReverse /abc-oper balancer://agentcluster/abc-oper
        ProxyPreserveHost on

        SetEnv force-proxy-request-1.0 1
        SetEnv proxy-nokeepalive 1

        <Proxy *>
         Order deny,allow
         Allow from all
        </Proxy>

        ErrorLog /apps/apache/logs/agent.abconline.com.error.log
        CustomLog /apps/apache/logs/agent.abconline.com.access.log combined
        LogLevel debug
</VirtualHost>

<VirtualHost *:80>
        ServerName staging.abconline.com
        RewriteEngine On

        <Proxy balancer://stagingcluster>
         BalancerMember http://192.168.0.1:7003 route=1 loadfactor=50 retry=60
         BalancerMember http://192.168.0.2:7003 route=1 loadfactor=50 retry=60
        </Proxy>

        # Redirect all non-static requests to agent
        RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
        RewriteRule ^/(.*)$ balancer://stagingcluster%{REQUEST_URI} [P,QSA,L]

        ProxyPass /abc-oper balancer://stagingcluster/abc-oper
        ProxyPassReverse /abc-oper balancer://stagingcluster/abc-oper
        ProxyPreserveHost on

        SetEnv force-proxy-request-1.0 1
        SetEnv proxy-nokeepalive 1

        <Proxy *>
         Order deny,allow
         Allow from all
        </Proxy>

        ErrorLog /apps/apache/logs/staging.abconline.com.error.log
        CustomLog /apps/apache/logs/staging.abconline.com.access.log combined
        LogLevel debug
</VirtualHost>

你没有将适当的 /agent 和 /staging 上下文添加到反向代理规则中，并且显然在返回时删除了这些上下文，例如：

RewriteRule      / balancer://stagingcluster/staging%{REQUEST_URI} [P,QSA,L]
ProxyPassReverse / balancer://stagingcluster/staging


# Possibly also require a:
#ProxyHTMLURLMap balancer://stagingcluster/staging   /
