apache2.2配置

编译要求支持的组件：

LoadModule proxy_module modules/mod_proxy.soLoadModule proxy_connect_module modules/mod_proxy_connect.soLoadModule proxy_http_module modules/mod_proxy_http.soLoadModule proxy_balancer_module modules/mod_proxy_balancer.soLoadModule alias_module modules/mod_alias.soLoadModule rewrite_module modules/mod_rewrite.so

编辑主配置文件：conf/httpd.conf，再文件结尾加入：

ProxyRequests OffProxyPreserveHost on

打开虚拟主机配置的Include

#Include conf/extra/httpd-vhosts.conf

 修改为：

Include conf/extra/httpd-vhosts.conf

编辑虚拟主机配置文件 vi conf/extra/http-vhost.conf

 1.默认虚拟主机，使用ip或任意域名访问

# default host configuration for business and rm
    
       ErrorLog "logs/error_default.log"  LogLevel warn  CustomLog "logs/access_default.log" combinedio  ProxyPass / balancer://cluster-busi/ stickysession=jsessionid nofailover=Off  ProxyPassReverse / balancer://cluster-busi/  # business ab+lb, Horizontal expansion of multiple business nodes  
     
          BalancerMember  http://10.10.10.181:8013 loadfactor=5 retry=10    BalancerMember  http://10.10.10.182:8013 loadfactor=5 retry=10    ProxySet lbmethod=bybusyness  
     
    

2.域名访问

   支持: http://www.domain.com 和http://username.domain.com

   对于二级域名：http://username.domain.com先使用rewrite重写为：http://username.domain.com/username/，然后再使用proxy转发到下层的tomcat集群处理

    
         ServerName s3.amazonaws.com  ServerAlias *.s3.amazonaws.com    ErrorLog "logs/error_s3.log"    LogLevel warn  CustomLog "logs/access_s3.log" combinedio      RewriteEngine on    RewriteLog "logs/rewrite_s3.log"    RewriteLogLevel 3  RewriteCond %{HTTP_HOST} !^s3\.amazonaws\.com$  RewriteCond %{HTTP_HOST} ^.+\.s3\.amazonaws\.com$  RewriteRule /(.*) /%{HTTP_HOST}/$1    RewriteRule /(.+)\.s3\.amazonaws\.com/(.*)$ /$1/$2 [PT]  	ProxyPass / balancer://cluster-s3/ nofailover=Off    ProxyPassReverse / balancer://cluster-s3/    
     
            BalancerMember  http://localhost:8080/awsintf	 loadfactor=1 retry=10      BalancerMember  http://10.10.10.182:8013/oss loadfactor=5 retry=10      ProxySet lbmethod=byrequests    
     
    

tomcat集群配置略。
