I'm using apache2 as a local proxy balancer between the web and a jboss machine.
i've used the following configuration:
<Proxy balancer://mycluster>
BalancerMember http://localhost:8080
</Proxy>
ProxyPass /test balancer://mycluster
if i call my machine with www.mymachine.com/test then the call is passed to JBoss, but in the request it seems that it was called with 'localhost'.
how can I make sure the correct server name is passed as well?

all i needed to do is to add:
ProxyPreserveHost On

I have configured an Apache http server with mod_proxy to load balance between two jetty servers (sticky sessions).
Everything works fine and as expected while the two servers are up and running. But if I get one of the servers down and then attempt to make an http post to that server, the Apache balancer redirects the post to the running server but with an empty body, losing the original request.
After the request that triggered the redirect to the running server, all subsequent requests work fine.
Apache configuration:
<Proxy balancer://cluster>
BalancerMember http://localhost:9090 route=node1
BalancerMember http://localhost:9091 route=node2
ProxySet stickysession=JSESSIONID
</Proxy>
ProxyPreserveHost On
ProxyPass "/" "balancer://cluster/"
ProxyPassReverse "/" "balancer://cluster/"
I'm using Apache Server 2.4 and Jetty 9.4.22
Any ideas on why this is happening?
Thanks.
It looks like you hit the bug introduced as a regression in 2.4.41. You can check out the details here: https://bz.apache.org/bugzilla/show_bug.cgi?id=63891
To remedy, you will need to upgrade to 2.4.42 or greater.
I have used the proxypass and reverse proxypass inside the httpd.conf in apache server to repoints requests to particular JVM in JBoss server.
I have 2 JBoss servers...during a failover test..one JBoss server is stopped abruptly...the apache cant identifies that the one JBoss server is stopped and hence cant redirect request to the other server.
Any help on this?
try
<Proxy balancer://BALANCER_NAME>
BalancerMember https://foo1.bar:443 ping=1 loadfactor=1
BalancerMember https://foo2.bar:443 status=+H ping=1
</Proxy>
ProxyPass / balancer://BALANCER_NAME/
ProxyPassReverse / balancer://BALANCER_NAME/
In this configuration all is sent to foo1 and foo2 is in hot standby (status=+H)
I have an Endeca cluster setup with 3 dgraph(1 EAC Central Server and 2 EAC agent only instances). I am trying to put an Apache mod_proxy load balancer for testing purpose before the MDEX engines(I am using presentation API to hit the MDEX engine(we are working on assembler API also)). We shall be having an F5(or Nginx, which one shall be better?) hardware load balancer when we'll shall do the actual deployment. My apache server is listening at port 5555, All my Dgraphs are running at port 15000 on three different host. I'm directing the all my queries to apache load balancer.
MDEX_HOST = localhost
MDEX_PORT = 5555
private static ENEConnection createConnection() {...}
And here is my Apache Load balancer configuration. Load balancer modules included in httpd.conf file mod_proxy, mod_proxy_balancer, mod_proxy_connect, mod_proxy_http, mod_negotiation. I have put the load balancer configuration in httpd-vhosts.conf file.
NameVirtualHost *:5555
<VirtualHost *:5555>
Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/"

When I do a query(Type ahead service) I'm getting the following error..
** Error Fri Apr 10 20:05:53 IST 2015 1428676553858 /atg/rest/processor/RestActorManager Caused by (#6):com.endeca.navigation.ENEException: HTTP Error 404 - Navigation Engine not able to process request 'http://localhost:5555/search?terms=je&rank=0&offset=0&irversion=640'.
Can anyone please see my load balancer configuration what I'm doing wrong? Thanks
I currently have apache2 configured so that requests on specific urls such as /myapp are directed to my internal tomcat server at tomcathost:8080/myapp.
All the requests to myapp to apache2 work as expected.
The problem that I'm facing is that whenever a request is sent to myapp trough apache2 it seems that apache2 is keeping the connection open to tomcat and after a while all the threads in tomcat are taken by apache and apparently not released.
Could somebody point me in the right direction to solve this issue ?
ProxyPass /myapp balancer://apps/myapp
ProxyPassReverse /myapp balancer://apps/myapp
<Proxy balancer://apps>
BalancerMember http://appserver01:8080 route=Node01 loadfactor=1
BalancerMember http://appserver02:8080 route=Node02 loadfactor=1
ProxySet lbmethod=byrequests
ProxySet stickysession=JSESSIONID|jsessionid
ProxySet nofailover=On
</Proxy>
You can set connectiontime out in server.xml so incase if any thread is open it get timedout.
connectionTimeout="120000"
Also you might use JConsole which is part of JDK installation to monitor threads via JMX for your tomcat to see if there is any loop of threads which causes increase in threads.
When trying to make a proxy balancer work in my Oracle HTTP Server (based on Apache HTTP Server 2.2), I'm running into the following error, taken from the log file:
undefined symbol: ap_proxy_set_wstatus
It's a syntax error from the httpd.worker, and says that it cannot load the mod_proxy_balancer.so module into the server. Is this an issue where I need to re-download the module? Or is there something I need to add/edit in one of the configuration files?
Some more information:
The balancer is running out of a VirtualHost, and directing traffic through 2 virtual hosts on another server.
The following code (IP and port #s changed) is in a configuration file that is included in the httpd.conf file with the include statement:
>
Listen 1000
NameVirtualHost *:1000
<Proxy balancer://balancertest>
BalancerMember http://ipaddress:0000
BalancerMember http://ipaddress:0001
lbmethod=bybusyness
</Proxy>
<VirtualHost *:7946>
ProxyPass /texthere balancer://balancertest
ProxyPassReverse /texthere balancer://balancertest
</VirtualHost>
