[Bug 58512] New: balancer-manager losing settings on reload
https://bz.apache.org/bugzilla/show_bug.cgi?id=58512
Bug ID: 58512
Summary: balancer-manager losing settings on reload
Product: Apache httpd-2
Version: 2.4.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy_balancer
Assignee: bugs@httpd.apache.org
Reporter: bugreport@lamp-solutions.de
Following settings are applied in the VHost.conf:
ProxyRequests Off
ProxyVia Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Proxy balancer://mycluster>
BalancerMember http://192.168.11.31 loadfactor=8 retry=10
BalancerMember http://192.168.11.32 loadfactor=7 retry=10
BalancerMember http://192.168.11.33 loadfactor=10 retry=10
BalancerMember http://192.168.11.34 loadfactor=5 retry=10
BalancerMember http://192.168.11.35 loadfactor=10 retry=10
BalancerMember http://192.168.11.36 loadfactor=8 retry=10
</Proxy>
ProxyPass /balancer-manager !
ProxyPass / balancer://mycluster/
This settings worked very well with apache2.2 for about 5 years. And were
migrated to apache 2.4.7 on Ubuntu 14.04 LTS.
It's all fine, but sometimes it happens that some admins exclude some
balancer-members or change the loadfactor according the needings at the moment.
Problem:
When reloading the apache-service, e.g. through "logrotate" or simply an
adaption in the configuration, the settings defined in the balancer-manager are
going lost.
A similar issue had been reported in "44736" for apache2.2 and had been
resolved.

Hi Yann,
thank you! Works as expected.
I had the 2.2 bug in mind so I was confused.

You should use "BalancerPersist on" ([1]).
There were many improvements on mod_proxy_balancer in 2.4, one of those is
dynamic configuration via the balancer-manager, which does not persist by
default.
