Hello,
I am trying to add two extra workers, totaling 4 workers, but Apache
fails to restart.
This worker file works:
# List the workers name
worker.list=1,2,loadbalancer
If you only want to use workers 1 and 2 via the loadbalancer, you can
remove them from worker.list and only keep the loadbalancer there.
# ----------------
# First worker
# ----------------
worker.1.host=206.xx.xxx.xxx
worker.1.port=8019
worker.1.type=ajp13
worker.1.lbfactor=4
# ----------------
# Second worker
# ----------------
worker.2.host=206.xx.xxx.xxx
worker.2.port=8029
worker.2.type=ajp13
worker.2.lbfactor=5
Strange lbfactors ...
# ----------------------
# Load Balancer worker
# ----------------------
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=1,2,3,4
This can't work, since the loadbalancer has no idea what you mean by
worker 3 and 4 ...
BUT WHEN I change to:
worker.list=1,2,3,4,loadbalancer
Same comment as above concerning worker.list
worker.1.host=206.xx..xx.xx
worker.1.port=8019
worker.1.type=ajp13
worker.1.lbfactor=4
worker.2.host=206.xx..xx.xx
worker.2.port=8029
worker.2.type=ajp13
worker.2.lbfactor=5
worker.3.host=206.xx..xx.xx
worker.3.port=8039
worker.3.type=ajp13
worker.3.lbfactor=1
worker.4.host=206.xx.xx.xx
worker.4.port=8049
worker.4.type=ajp13
worker.4.lbfactor=2
And there are connectors in the Tomcat configuration listening on those
ports 8019, ..., 8049, right?
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=1,2,3,4
I get these kind of errors, and Apache fails to start
[Tue Sep 07 00:36:37 2010] [18324:16360] [error] jk_lb_worker.c
(1536): allocating lb sub worker record from shared memory
There's a problem creating the workers when trying to access shared
memory. Could you please show us your complete mod_jk configuration,
especially the "Jk*" directives for Apache? Do you have an JkShmSize set?
Are there any info, warn or error messages during startup and before
this failure?

How do I allow Apache to communicate to 4 tomcats?
Exact HTTPD, Tomcat, mod_jk versions?

Rainer
