Apache HTTPD mod_proxy多个虚拟主机 URL 重定向的负载平衡

Question

scenario：
操作系统中心操作系统
网络服务器 Apache HTTP 版本 2.2.23
两个网络逻辑服务器群集
两台网络服务器

以上是硬件负载平衡器后面

基本上想对流量进行URL重定向和负载平衡（不修改会话）

当我输入 agent.abconline.com 时，它应该被重定向到应用程序服务器 192.168.0.1：7001/agentstaging.abconline.com 应重定向到 192.168.0.1;7001/暂存

上面说我可以单独使用mod_rewrite，但是在尝试使用mod_proxy和负载平衡时，我无法重定向到所述URL

以下是配置

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>

您没有将适当的 /agent 和 /stage 上下文添加到反向代理规则中，并且显然在返回过程中删除了上下文，例如

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

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