Hi,
I don't know if this can help but this is how I managed to get a working
load-balancing of my GlassFish v3.1 cluster with mod_jk.
*Cluster setup* : localhost with 3 instances and laptop-host with 1 instance
(openssh installed and configured on both hosts)
- asadmin create-cluster cluster1
- asadmin setup-ssh --sshuser fabien laptop-host
- asadmin create-node-ssh --nodehost laptop-host --sshuser fabien
--installdir /home/fabien/glassfish3 node-laptop
- asadmin create-local-instance --cluster cluster1 instance1
- asadmin create-local-instance --cluster cluster1 instance2
- asadmin create-local-instance --cluster cluster1 instance3
- asadmin create-instance --cluster cluster1 --node node-laptop instance4
- asadmin start-cluster cluster1
*Cluster configuration for mod_jk :*
- asadmin create-jvm-options --target cluster1
"-DjvmRoute=\${AJP_INSTANCE_NAME}"
- asadmin create-jvm-options --target cluster1
"-Dcom.sun.enterprise.web.connector.enableJK=\${AJP_PORT}"
- asadmin create-system-properties --target instance1
AJP_INSTANCE_NAME=instance1
- asadmin create-system-properties --target instance1 AJP_PORT=8009
- asadmin create-system-properties --target instance2
AJP_INSTANCE_NAME=instance2
- asadmin create-system-properties --target instance2 AJP_PORT=8010
- asadmin create-system-properties --target instance3
AJP_INSTANCE_NAME=instance3
- asadmin create-system-properties --target instance3 AJP_PORT=8011
- asadmin create-system-properties --target instance4
AJP_INSTANCE_NAME=instance4
- asadmin create-system-properties --target instance4 AJP_PORT=8009
*httpd.conf* :
<code>
# Load mod_jk module
LoadModule jk_module
/usr/local/apache2/lib/mod_jk-1.2.31-httpd-2.2.x.so
# Where to find workers.properties
JkWorkersFile /usr/local/apache2/conf/workers.properties
# Where to put jk shared memory
JkShmFile /usr/local/apache2/logs/mod_jk.shm
# Where to put jk logs
JkLogFile /usr/local/apache2/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkMount /* loadbalancer
</code>
*workers.properties* :
<code>
# Define 1 real worker using ajp13
worker.list=loadbalancer
#Set properties for instance1
worker.instance1.type=ajp13
worker.instance1.host=localhost
worker.instance1.port=8009
worker.instance1.lbfactor=50
worker.instance1.socket_keepalive=1
worker.instance1.socket_timeout=300
#Set properties for instance2
worker.instance2.type=ajp13
worker.instance2.host=localhost
worker.instance2.port=8010
worker.instance2.lbfactor=50
worker.instance2.socket_keepalive=1
worker.instance2.socket_timeout=300
#Set properties for instance3
worker.instance3.type=ajp13
worker.instance3.host=localhost
worker.instance3.port=8011
worker.instance3.lbfactor=50
worker.instance3.socket_keepalive=1
worker.instance3.socket_timeout=300
#Set properties for instance4
worker.instance4.type=ajp13
worker.instance4.host=laptop-host
worker.instance4.port=8009
worker.instance4.lbfactor=50
worker.instance4.socket_keepalive=1
worker.instance4.socket_timeout=300
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=instance1,instance2,instance3,instance4
</code>
And finally restart GlassFish and Apache.
I have never had any problem with create-system-properties or
create-jvm-options subcommands. What error do you have ?
Regards,
Fabien Leroy.
