.... to be continued ...

Method 2 - RPM Installation

After registering for a Red Hat Developer subscription, you can enable the following repo :

subscription-manager repos --disable=* --enable=jb-eap-7.3-for-rhel-7-server-rpms

Assuming we decide to install JBoss EAP and JDK8 (JDK for Java 1.8), then

yum -y groupinstall jboss-eap7

Set the system java as JDK1.8 by

alternatives --config java

Note the options shown on screen and select the number for java-1.8.0-openjdk.x86_64

Confirm the version by

java -version

For RPM installation method, the JBoss EAP service definitions would have been created after the install.

List the services by

systemctl list-unit-files --type service | grep -i eap

The output will be :-

eap7-domain.service disabled
eap7-standalone.service disabled

Configure a Standalone Server

systemctl enable eap7-standalone

systemctl start eap7-standalone

For a default installation, the EAP_HOME is /opt/rh/eap7/root/usr/share/wildfly

Create the admin user

/opt/rh/eap7/root/usr/share/wildfly/bin/add-user.sh -u 'admin' -p 'training'

The output will look like:

Updated user 'admin' to file '/etc/opt/rh/eap7/wildfly/standalone/mgmt-users.properties'
Updated user 'admin' to file '/etc/opt/rh/eap7/wildfly/domain/mgmt-users.properties'

Restart the standalone server and tail the server log

systemctl restart eap7-standalone

tail -f /opt/rh/eap7/root/usr/share/wildfly/standalone/log/server.log

The default http application is http://localhost:8080

The default https application is https://localhost:8443

Configure a Domain

systemctl enable eap7-domain

systemctl start eap7-domain

If the user was not created yet, create by running the add-user.sh script under $EAP_HOME/bin directory

/opt/rh/eap7/root/usr/share/wildfly/bin/add-user.sh -u 'admin' -p 'training'

In the default configuration, the management console http://localhost:9990 is as shown below

The default config has 3 servers in 2 groups
