使用多个虚拟主机url重定向的apache mod_proxy负载平衡

Question

设想情况：

OS centos

webserver apache http版本2.2.23

两个weblogic服务器集群

两个网络服务器

以上是硬件负载均衡器的后面。

基本上是想做url重定向和负载平衡(而不修改会话)的流量。

当我输入agent.abconline.com时，它应该被重定向到app服务器192.168.0.1:7001/代理staging.abconline.com应该被重定向到192.168.0.1；7001/分期

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，我无法被重定向到所述的URL

下面是配置

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上下文。

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


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