求助:我的APACHE配置哪儿有问题？

[林子一]

想实现APACHE虚拟机的配置
有2个域名www.a.xx和bbs.a.xx，输入任何的*.a.xx访问的是www.a.xx(IP地址是192.168.0.30)
www.a.xx ==> /virHost/www/wwwroot ==>JSP映射到tomcat的192.168.0.30:6008
bbs.a.xx ==> /virHost/bbs/wwwroot ==>JSP映射到tomcat的192.168.0.30:7008
*.a.xx ==> 映射到默认主页 www.a.xx
目前我在Linux下tomcat服务器配置正常，APACHE不整合Tomcat，单独无多域名的测试页正常
但是我把通过编译好的mod_jk.so连接Tomcat时就报错了，我是计划这样
*.a.xx ==>通过workers.properties和uriworkermap.properties映射Tomcat
www.a.xx ==>通过workers.properties和wwwworkermap.properties映射Tomcat
bbs.a.xx ==>通过workers.properties和bbsworkermap.properties映射Tomcat
httpd.conf的主要配置文件如下：
我已经加上了以下这句，mod_jk.so我已经编译确定没问题，并在modules文件下有存折
LoadModule jk_module modules/mod_jk.so
在配置文件的末尾我加上
JkWorkersFile /usr/local/apache2/conf/workers.properties
JkMountFile /usr/local/apache2/conf/uriworkermap.properties
JkMount /* wwwtmc
JkLogFile /usr/local/apache2/logs/mod_jk.log
JkLogLevel info
JkLogStampformat "[%a %b %d %H:%M:%S %Y]"
NameVirtualHost *:80
<VirtualHost *:80>

JkMount /* wwwtmc

workers.properties配置信息如下：
worker.list=wwwtmc,bbstmc
worker.wwwtmc.port=6009
worker.wwwtmc.host=www.a.xx
worker.wwwtmc.type=ajp13
worker.wwwtmc.lbfactor=1
worker.bbstmc.port=7009
worker.bbstmc.host=bbs.a.xx
worker.bbstmc.type=ajp13
worker.bbstmc.lbfactor=1
以下
uriworkermap.properties
wwwworkermap.properties
bbsworkermap.properties
大体相同，内容如下（只是bbsworkermap.properties中wwwtmc是bbstmc）：
/*=wwwtmc
!/*.jpg=wwwtmc
!/*.gif=wwwtmc
!/*.png=wwwtmc
!/*.bmp=wwwtmc
!/*.html=wwwtmc
!/*.htm=wwwtmc
!/*.swf=wwwtmc
!/*.css=wwwtmc
!/*.js= wwwtmc
输入http://www.a.xx显示如下503错误信息
Service Temporarily Unavailable

我该咋办呢？
