Chapter 3. Launching a Non-clustered JBoss EAP Instance
This chapter lists the steps to launch a non-clustered instance of JBoss EAP on a Red Hat Amazon Machine Image (AMI).
Prerequisites
- A suitable Red Hat AMI. See Supported Red Hat AMIs for more information.
- A pre-configured Security Group that allows incoming requests on at least ports 22, 8080, and 9990.
Launch a Non-Clustered JBoss EAP Instance
You can connect to an EC2 instance through ssh as the ec2-user user. If you need administrative privileges, you can change to root user later. For example,
$ ssh -l ec2-user ${INSTANCE_PUBLIC_IP}
...
$ sudo su -Launch the Red Hat AMI instance.
A non-clustered instance of JBoss EAP has been configured and launched on a Red Hat AMI.
To configure JBoss EAP, you can pass arguments to the service directly. Some arguments may not be handled in this way. The location of the service configuration files is:
-
RHEL 6:
/etc/sysconfig/eap7-standalone -
RHEL 7:
/etc/opt/rh/eap7/wildfly/eap7-standalone.conf
See System Paths for more details about system paths.
-
RHEL 6:
-
For complex configuration, you can either use the
standalone.conffile in the JBoss EAPbindirectory:/opt/rh/eap7/root/usr/share/wildfly/bin/, or you can start the JBoss EAP service and configure the server using CLI. The script can be found in thebindirectory. Then, reload the configuration. -
You must regularly run the
yum -y updateto apply security fixes and enhancements.
To start JBoss EAP on RHEL 6, run the following command:
$ service eap7-standalone start
To start JBoss EAP on RHEL 7, run the following command:
$ systemctl start eap7-standalone
To stop JBoss EAP on RHEL 6, run the following command:
$ service eap7-standalone stop
To stop JBoss EAP on RHEL 7, run the following command:
$ systemctl stop eap7-standalone
NoteThe
systemctlcommand is relevant to only RHEL 7.
If you want to bind JBoss EAP to a different IP address, add the following line in the /etc/opt/rh/eap7/wildfly/eap7-standalone.conf file on RHEL 7. The internal IP address is translated into a public IP address by EC2.
