Configuration and goal > * two web apps, [^clusterbench.war] and [^tses.war], both deployed on each of two tomcats > * one web app is in excluded contexts (it is [^tses.war]) > * the other one ([^clusterbench]) is registered with mod_cluster balancer > * main server: {{\*:2080}} > * mod_cluster VirtualHost: {{\*:8747}} > * proxyPass BalancerMember VirtualHost {{\*:2081}} > * I want to access [^clusterbench.war] via {{\*:8747}} and {{\*:2080}} (works (/)), and [^tses.war] via {{\*:2081}} (fails (x)) > * see [^proxy_test.conf] for BalancerMember configuration (taken from httpd 2.2.26 test run, you must edit Location access) > * see [^mod_cluster.conf] for mod_cluster configuration (taken from httpd 2.2.26 test run, as above) > h3.

About the test > This test has always been failing in one way or another: not serving URL (HTTP 404), returning All workers in Error state (HTTP 503). SegFault has been slipping under the radar for some time, because the test ended up on assert earlier in the scenario - on the first HTTP 503. > We should clearly document which BalancerMember integration is supported and which is not. Furthermore, we must not SegFault even if user tries to do something weird, we must log an error message instead. -- This message was sent by Atlassian JIRA (v7.2.2#72004)

[JBoss JIRA] (MODCLUSTER-391) mod_cluster and mod_proxy integration

by Jean-Frederic Clere (JIRA)

[ https://issues.jboss.org/browse/MODCLUSTER-391?page=com.atlassian.jira.pl... ] Jean-Frederic Clere updated MODCLUSTER-391: ------------------------------------------- Fix Version/s: 1.3.5.Final (was: 1.3.4.Final) > mod_cluster and mod_proxy integration > ------------------------------------- > > Key: MODCLUSTER-391 > URL: https://issues.jboss.org/browse/MODCLUSTER-391 > Project: mod_cluster > Issue Type: Bug > Affects Versions: 1.2.6.Final > Environment: All platforms we build mod_cluster for. > Reporter: Michal Karm Babacek > Assignee: Jean-Frederic Clere > Labels: native_libraries > Fix For: 1.2.14.Final, 1.3.5.Final > > Attachments: error_log, mod_cluster.conf, mod_proxy.conf, standalone-ha.xml > > > This Jira encapsulates all concerns regarding mod_cluster - mod_proxy integration. For instance, while basic {{ProxyPass}} settings work just fine, e.g. serving some files on {{/static}} from the Apache HTTP itself: > {code} > ProxyPassMatch ^/static/ ! > ProxyPass / balancer://qacluster stickysession=JSESSIONID|jsessionid nofailover=on > ProxyPassReverse / balancer://qacluster > ProxyPreserveHost on > {code} > there are more complex setups, involving {{BalancerMember}} configurations, that do not work as expected. In the following example, one wanted to have {{/clusterbench}} application managed by mod_cluster, dynamically, while at the same time, in a different VirtualHost, having {{/tses}} application handled by manually created mod_proxy balancer settings. > Attached [^mod_cluster.conf], [^mod_proxy.conf], [^standalone-ha.xml](modcluster subsystem element only) and [^error_log]. > The aforementioned setup resulted in: > |HTTP 200|(From worker)|http://10.16.88.19:8847/clusterbench/requestinfo/|OK|(/)| > |HTTP 404|(From httpd)|http://10.16.88.19:8847/tses/session.jsp|Expected fail|(/)| > |HTTP 503|(From httpd)|http://10.16.88.19:2182/tses/session.jsp|Unexpected fail|(x)| -- This message was sent by Atlassian JIRA (v7.2.2#72004)
