Multiple Domain Controlers with single JBoss(EAP 6.4.5) Installation

sukeshpeddolla Jun 9, 2016 11:43 AM

Hello,

Is there a way to create multiple domain controllers with single JBoss installation, reason is we have two applications using same domain.xml and when ever we do app server config( adding JDBC resources, MQ resources) we need to bounce the complete domain.

In this case the other application is getting effected, to avoid this we thought if we have multiple domain controllers with single installations( we tested backup domain controller option with separate installation successfully).

OS: Red Hat Enterprise Linux Server release 6.7 (Santiago)

JBoss: EAP 6.4.5 GA

I followed below steps to create multiple domain controllers:

1). copied complete domain folder and renamed it to domain1

2). under JBOSS_HOME/bin directory , created another set of domain1.conf and domain1.sh

changed JBOSS_LOG_DIR, JBOSS_BASE_DIR, JBOSS_CONF_DIR references

changed management port to 29999

changed native http port to 29990

3). Tried to start domain controller with below command:

./domain1.sh --domain-config=/apps/jboss/jboss-eap-6.4.0/domain1/configuration/domain.xml --host-config=/apps/jboss/jboss-eap-6.4.0/domain1/configuration/host

and getting below error.

Not sure where I am missing the references or is it possible at all to create multiple domain controllers with single JBoss installation

If any one has successfully created multiple domain controllers with single JBoss Installation, please list the complete steps here.

I really appreciate your help, thank you in advance !

Please run the below command:
./domain1.sh -Djboss-domain.base.dir=/home/aa/Desktop/Jboss-Practice-EAP6/Domain/domain1/ --domain-config=domain.xml --host-config=host.xml

Can't be your problem solved with server-groups? You are able to restart only one server-group at the moment - no need to restart whole domain.

Amit, Thank you for your suggestion. It worked with below command.
./domain1.sh -Djboss-domain.base.dir=/apps/jboss/jboss-eap-6.4.0/domain1/ -Djboss.domain.config.dir=/apps/jboss/jboss-eap-6.4.0/domain1/configuration/ --domain-config=domain.xml --host-config=host.xml

now the second domain controller is up and running with 29990 and 29999 ports

But if i want to connect jboss-cli for domain1(second domain controller), what needs to be done ..?

I have set of jboss-cli1.xml and jboss-cli1.sh, when i try to run jboss-cli1.sh, it is still trying to connect to the base "domain"(9999) not the "domain1"(29999)

I checked the references and couldn't find any, is there any way to connect to jboss-cli1.sh by passing run time parameters..?

Thanks,
Sukesh

sukeshpeddolla Jun 17, 2016 11:56 AM (in response to amit12345)

Amit, thank you ! It worked and i was able to create multiple domain controllers with single jboss installation.

Tested on both Primary and slave hosts, adding all the steps here which could be useful for others.

Multiple Domain Controllers setup with single JBoss Installation:

on JBoss Primary Node:

1). Login to the Target JBoss server

2). mkdir -p /tmp/deploy/backups/`date +"%m-%d-%y`

3). cd /apps/jboss

4). tar -cvzf /tmp/deploy/backups/`date +"%m-%d-%y`/jboss-eap-6.4.0.tgz jboss-eap-6.4.0/*

5). chmod 000 /tmp/deploy/backups/`date +"%m-%d-%y`/jboss-eap-6.4.0.tgz

6). cd /apps/jboss/jboss-eap-6.4.0

7). cp -r domain domain1 (creating another set of domain folder)

8). cd /apps/jboss/jboss-eap-6.4.0/domain1
    Make the chnages to domain.xml and host.xml

    (Note: change the profile name, server group, member name, hostname, ips accordingly)

9). cd /apps/jboss/jboss-eap-6.4.0/bin

10). cp domain.sh domain1.sh

11). cp domain.conf domain1.conf

12). vi domain1.sh
     change from
JBOSS_BASE_DIR="$JBOSS_HOME/domain
to
JBOSS_BASE_DIR="$JBOSS_HOME/domain1

chnage from
DOMAIN_CONF="$DIRNAME/domain.conf
to
DOMAIN_CONF="$DIRNAME/domain1.conf
save

13). start domain
     cd /apps/jboss/jboss-eap-6.4.0/bin
./domain1.sh -Djboss-domain.base.dir=/apps/jboss/jboss-eap-6.4.0/domain1/ -Djboss.domain.config.dir=/apps/jboss/jboss-eap-6.4.0/domain1/configuration/ --domain-config=domain.xml --host-config=host.xml &
     make sure domain1 up and looks good

14). connect to jbosscli
     cd /apps/jboss/jboss-eap-6.4.0/bin
./jboss-cli.sh -c --controller=ip:29999
make sure to connect successfully
exit

15). Login to JBoss admin console
     http://hostname:29990/console

on JBoss Slave Node:
1). Login to the Target JBoss server

2). mkdir -p /tmp/deploy/backups/`date +"%m-%d-%y`

3). cd /apps/jboss

4). tar -cvzf /tmp/deploy/backups/`date +"%m-%d-%y`/jboss-eap-6.4.0.tgz jboss-eap-6.4.0/*

5). chmod 000 /tmp/deploy/backups/`date +"%m-%d-%y`/jboss-eap-6.4.0.tgz

6). cd /apps/jboss/jboss-eap-6.4.0

7). cp -r domain domain1 (creating another set of domain)

8). cd /apps/jboss/jboss-eap-6.4.0/domain1
    Make the chnages to host.xml
   (Note: change the profile name, server group, member name, hostname, ips accordingly)

9). cd /apps/jboss/jboss-eap-6.4.0/bin

10). cp domain.sh domain1.sh

11). cp domain.conf domain1.conf

12). vi domain1.sh
     change from
JBOSS_BASE_DIR="$JBOSS_HOME/domain
to
JBOSS_BASE_DIR="$JBOSS_HOME/domain1

chnage from
DOMAIN_CONF="$DIRNAME/domain.conf
to
DOMAIN_CONF="$DIRNAME/domain1.conf
save

13). start domain
     cd /apps/jboss/jboss-eap-6.4.0/bin
./domain1.sh -Djboss-domain.base.dir=/apps/jboss/jboss-eap-6.4.0/domain1/ -Djboss.domain.config.dir=/apps/jboss/jboss-eap-6.4.0/domain1/configuration/ --host-config=host.xml &
     make sure domain1 up and looks good

on JBoss Primary node:

1). Verify /apps/jboss/jboss-eap-6.4.0/domain1/log/hostcontroller.log and make sure all the slave nodes registered with primary node

2). start servers
     connect to jbosscli
    ./jboss-cli.sh -c --controller=ip:29999
:start-servers()

3). verify the /apps/jboss/jboss-eap-6.4.0/domain1/log/"server"/server.log on all servers

4). if you want to add user to domain1, run below command

    ./add-user.sh -dc /apps/jboss/jboss-eap-6.4.0/domain1/configuration/

Amit, servers started fine with above settings, but some times we are seeing the below error in server,log.

data/content/0d/b162f14f559819e595215439385e6d8a83dc4f is obsolete and will be removed

it is happening some times, found below thread on that, but this wasn't much useful. And again we have to deploy the same code remove the above error.

https://developer.jboss.org/thread/252308?start=0&tstart=0

it is happening with newly created domain, previous one works absolutely fine.

Any thoughts ..?
