mod-rewrite - apache httpd mod_proxy 负载平衡与多个虚拟主机 URL 重定向

Question

场景:
操作系统centos
网络服务器 apache http 版本 2.2.23
两台 weblogic 服务器集群
两个网络服务器

以上是在硬件负载均衡器后面

主要是想做url重定向和流量负载均衡(不修改session)

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/staging

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 /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   /
