Load Balancing, Apache, Debian, mod_proxy_balancer for Wordpress, vBulletin & vBSEO

[wowglider]

Hello,
ive 1 forum with atm not so much traffic to load balance it, but i know it would be better for the next years, so i bought a 2. server to load balance all vhosts i have on them.

Thats my configuration:
server1.worldofglider.de
Intel? Core? i7-920 Quad-Core
inkl. Hyper-Threading-Technologie
Arbeitsspeicher 8 GB DDR3 RAM
Festplatten 2 x 750 GB SATA-II HDD (Software-RAID 1)
Netzwerkkarte 1 GBit OnBoard mit 100 MBit-Anbindung
Backup Space100 GB
Traffic Unlimited

server2.worldofglider.de
Intel? Core? i7-920 Quad-Core
inkl. Hyper-Threading-Technologie
Arbeitsspeicher 8 GB DDR3 RAM
Festplatten 2 x 750 GB SATA-II HDD (Software-RAID 1)
Netzwerkkarte 1 GBit OnBoard mit 100 MBit-Anbindung
Backup Space100 GB
Traffic Unlimited

Because i just have 2 server to load balance some of the servers need to do the apache thing + load balancer.

My idea was installing load balancer on server1 on port 80 and http on port 81. Is that possible?

Now i have one problem, the load balancer dont seem to pass (the right?) vhost to http server1 or 2.

Thats my load balancer config:

NameVirtualHost *:80
<VirtualHost *:80>
        DocumentRoot /home/load-balancer
        ProxyRequests Off

        <Proxy *>
          Order deny,allow
          Allow from all
        </Proxy>
        ProxyPass /LB !
        ProxyPass / balancer://mycluster/ stickysession=1 nofailover=On
        ProxyPassReverse / http://server1.worldofglider.de/
        ProxyPassReverse / http://server2.worldofglider.de:81/
        <Proxy balancer://mycluster>
          BalancerMember http://server1.worldofglider.de  route=server1
          BalancerMember http://server2.worldofglider.de:81  route=server2
          ProxySet lbmethod=byrequests
        </Proxy>
        <Location /LB>
          SetHandler balancer-manager
          Order deny,allow
          Allow from all
        </Location>
</VirtualHost>

Thats how i installed the vHosts on port 81:

<VirtualHost *:81>
        RewriteEngine On
        RewriteRule .* - [CO=BALANCEID:balancer.server2:.worldofglider.de]
        ServerAdmin webmaster@localhost
        ServerName www.fairplay-bot.de
        ServerAlias fairplay-bot.de
        DocumentRoot /home/ftp/fairplay-bot.de/
</VirtualHost>

Someone has an idea why my vhosts not working? Also i have another question, i installed rsync to sync server2 with server1, but what happens when some user create content on server2? How i can pass this to server 1?

Maybe i could get some help from the big board owners, if i posted in the wrong section im really sorry.

Thanks for any help!
