I posted this earlier in the week and have seen no replies so I figured I would
post again.
Thanks.
Good afternoon,
I have a webfarm made up of Apache servers running a Joomla website - running
on CentOS 5.5 servers. This also includes two separate data centers with
haproxy running in each of them and a round robin dns with 15 minutes TTL's.
Here are snippets from my current haproxy.cfg file:
global
maxconn 4096 # Total Max Connections. This is dependent on ulimit
daemon
nbproc 8 # Number of processing cores. Dual Dual-core Opteron is 4 core$
log 127.0.0.1 local0
log 127.0.0.1 local1 notice
defaults
log global
option httplog
option dontlognull
retries 3
option redispatch
maxconn 10000
contimeout 1800000
clitimeout 1800000
srvtimeout 1800000
listen webfarm xxx.xxx.xxx.xxx:80
mode http
balance roundrobin
cookie SERVERID insert indirect nocache
option forwardfor
option httpchk HEAD /srvhealth.txt HTTP/1.0
server web1.mysite.com xxx.xxx.xxx.221:80 cookie webfarm_web1 check
server web2.mysite.com xxx.xxx.xxx.222:80 cookie webfarm_web2 check
These would be the same in each DC with the exception of the server name -
which might be web10, etc. for the second DC.
I had reports today that some end users were getting the joomla inactivity
screen during their session when navigating to different pages on the web site.
It looked like they had jumped to the second data center which would explain
why they got the screen. I have taken the second DC out of the mix for the time
being.
I was still getting some reports of this inactivity screen when the user was on
one or the other web servers in the single DC...and again it looks like they
jumped from one server to the other. I know that the inactivity screen is not
from haproxy but it seems that the end user is shifting web servers which is
what is causing the issue.
Once the user connects we want them to continue to hit the same server until
they log out of their session. Is this the correct configuration to accomplish
it? Is there a way running multiple DC's to keep them from jumping to another
DC after they already have a session open?
I thank you in advance for any guidance.
Please let me know if there is any additional data needed.
