Starting a specific JBOSS server profile and a specific ip-address

 A. Starting a specific JBOSS server profile :

1. Navigate to the path …\jboss-eap-5.1\jboss-as\server

2. The server folder has different profile. Create a duplicate copy of the default folder and rename it to server1. We can  customize this profile and start it.

3. To start server1 , navigate to the path …\jboss-eap-5.1\jboss-as\bin\ and open the command prompt.

4. Enter the command  run -c server1 ( “-c” is used to choose the profile name)

Once, the command is executed the server1 profile starts

5. To check the console, go to http://localhost:8080/jmx-console

im7

6. Enter the Username and Password (I have used my credentials to log in, we will cover how to manage user credentials password later in this article). The JMX Agent View console is displayed:

im8

B. Starting a specific JBOSS server on a given IP-Address :

1. Repeat steps 1-3 in section A.

2. Enter the command  run -c server1 -b ip-address ( “-b” is used to run the server on the specific ip-address)

Installing JBoss EAP as a windows service

1. Copy …\jboss-ep-5.1\native\sbin to …\jboss-eap-5.1\jboss-as\bin

2.  Locate the cmd.exe file in the path  C:\Windows\System32\ and right click to Run as administrator.

The following command prompt is displayed:

im10

3.  Navigate to the path  …\jboss-eap-5.1\jboss-as\bin\ in the command prompt and execute the command service.bat install

im11

The service JBEAP5SVC -SERVER1 has been created.

4. We can start and stop the service from the Task Manager.

Managing Password in JBOSS EAP

1. Navigate to …\jboss-eap-5.1\jboss-as\server\server1\conf\props .

2.  Open the jmx-console-roles.properties file and add roles as required.  I added the role saky , which I use to  login to jmx-console. Refer the sample file

# A sample roles.properties file for use with the UsersRolesLoginModule

admin=JBossAdmin,HttpInvoker
saky=JBossAdmin,HttpInvoker

3. Similarly, Open the jmx-console-users.properties file and edit passwords for the users. 

# A sample users.properties file for use with the UsersRolesLoginModule
admin=admin
saky=saky

Important: jmx-console is mapped in login-config.xml  ( …\jboss-eap-5.1\jboss-as\server\server1\conf\ ).

<application-policy name=”jmx-console”>
<authentication>
<login-module code=”org.jboss.security.auth.spi.UsersRolesLoginModule”
flag=”required”>
<module-option name=”usersProperties”>props/jmx-console-users.properties</module-option>
<module-option name=”rolesProperties”>props/jmx-console-roles.properties</module-option>
</login-module>
</authentication>
</application-policy>

Note: Restart the server if any changes are made in any of these configuration settings

Starting the default JBOSS server

1. Navigate to the path …\jboss-eap-5.1\jboss-as\bin\ and open the command prompt.

2. Enter the command run.bat to start the JBOSS server
