apache+tomcat配置动态二级域名
apache2.2配置编译要求支持的组件：
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule alias_module modules/mod_alias.so
LoadModule rewrite_module modules/mod_rewrite.so
编辑主配置文件：conf/httpd.conf，再文件结尾加入：
ProxyRequests Off
ProxyPreserveHost 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
<VirtualHost *:80>
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
<Proxy balancer://cluster-busi>
BalancerMemberhttp://10.10.10.181:8013 loadfactor=5 retry=10
BalancerMemberhttp://10.10.10.182:8013 loadfactor=5 retry=10
ProxySet lbmethod=bybusyness
</Proxy>
</VirtualHost>
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
<VirtualHost *:80>
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
ProxyPass / balancer://cluster-s3/ nofailover=Off
ProxyPassReverse / balancer://cluster-s3/
<Proxy balancer://cluster-s3>
BalancerMemberhttp://localhost:8080/awsintf loadfactor=1 retry=10
BalancerMemberhttp://10.10.10.182:8013/oss loadfactor=5 retry=10
ProxySet lbmethod=byrequests
</Proxy>
</VirtualHost>
tomcat集群配置略。
