Quickly setup EAP in Domain
Single host (OS)
1 - Domain Controller
2 - Nodes
Domain
Change the host config, (if you do not change then command line domain.sh --host-config=host-master.xml
mv host-master.xml host.xml
Note: If using HA profiles, hornetq cluster admin/password need to be set (can be done in Web Console as well) — not the same as the account created by ./add-user.sh
Note: If multiple profiles using hornetq ha, then user & password both must be unique
Add cluster-user element, it may not already be in the config
This add the "<cluster-user>" to the domain.xml, above "<cluster-password>"
<cluster-user>admin</cluster-user>
<cluster-password>passw0rd!</cluster-password>
Add admin management user (web console) i.e. admin
./add-user.sh
Add domain management user, i.e. mgmt
./add-user.sh
Answer “yes” to below:
Is this new user going to be used for one AS process to connect to another AS process? e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls.
To represent the user for the host add the following to the server-identities definition
<secret value="cGFzc3cwcmQh" />
Node (repeat for each node, separate folder or server)
Change the host config
mv host-slave.xml host.xml
Modify host.xml to add name attribute
<host name="host1" xmlns="urn:jboss:domain:1.7">
Modify host.xml server identity secret (use the secret created for the domain, i.e. mgmt user)
<secret value="cGFzc3cwcmQh"/>
Modify node host controller management interface port, increment by 1000 for each host if on the same OS
<socket interface="management" port="${jboss.management.native.port:10999}"/>
Starting the environment
Domain
Start the domain controller by running "domain.sh" each
Node(s)
Start each node by running "domain.sh -Djboss.domain.master.address=<DOMAIN_IP>"
Notes
When adding a server group, specifying for instance full-ha profile and using standard-sockets will result in an error because the full-ha profile needs additional socket bindings which aren’t defined in standard-sockets
Changing the server group socket binding, is not reflected in previously created server definitions on the host, need to manually edit those
To properly remove/clear up a server group, remove each server definition from each host, then remove the server group
I also noticed when using mod_cluster with Apache httpd. Multicast / advertise feature seems to have issues connecting when using OpenJDK 1.8 on RHEL7. With OpenJDK 1.7 on RHEL7, it appears to work fine. For either version, proxy-list will work regardless of OpenJDK version.
