We have configured an apache http server instance to serve as load balancer
between 3 aplications and 6 tomcat nodes, each application served by 2 nodes
each, using virtual host and mod_proxy_balancer.
This is the file which we use to set the first applicacion "A" to be served by
nodes sftomcat02 and sftomcat05. (conf.d/vh_a_tramix.conf)
Everything works as expected until this point:
- request are directed to the vh according to the url.
- request are balanced between tomcat nodes, session aware.
- if a node goes down, after a while, request are redirected to the surviving
node
But balancer shows only a balancer (the first one to be read?)
vh_a_tramix.conf follows:
<VirtualHost *:80>
ServerAdmin anotherguy
DocumentRoot "/var/www/html"
ServerName www.a.ar
ErrorLog logs/www.a.ar-error_log
CustomLog logs/www.a.ar-error_log-access_log common
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /balancer-manager !
ProxyPass / balancer://a/
#ProxyPassReverse / balancer://a/
<Proxy balancer://a>
BalancerMember ajp://sftomcat02:8029 route=tts2
#BalancerMember ajp://sftomcat05:8059 route=tts5
</Proxy>
ProxySet balancer://a stickysession=JSESSIONID nofailover=Off
<Location /balancer-manager>
SetHandler balancer-manager
Order deny,allow
Allow from all
</Location>
</VirtualHost>
similar vh are configured (say vh_b_tramix.conf and vh_c_tramix.conf)
but request to balancer-manager on this virtual hosts fails (tomcat node
responds, so... is not trapped even by the "ProxyPass /balancer-manager !"
directive).
I have tried to change "ProxyPass /balancer-manager !" to "ProxyPass
/balancer-manager2 !" (and changed rest of file 'accordingly') and still fails.
So, I kindly ask:
Is it necesary to change something? (version? config?)
Is this behaviour expected / to be changed?
Which task should I accomplish to solve this is issue (if possible)?
Does anybody have seen it working?
Thanks in advance for any help you can provide.
