Installing JBoss on CentOS 7

JBoss is a popular, open-source application server platform developed by Red Hat. It is based on Java Enterprise Edition (Java EE) and is optimized for high-performance, scalable, and transactional applications. JBoss provides a robust middleware solution that enables developers to build, deploy, and manage Java applications for a wide range of industries and use cases.

Step 1: Update System Packages

Before installing JBoss on CentOS 7, it is recommended to update the system packages to their latest versions. Open the terminal and run the following commands:

 $ sudo yum update 

Step 2: Install Java Development Kit (JDK)

JBoss requires Java Development Kit (JDK) to be installed on your CentOS 7 system. Execute the following command to install OpenJDK 8:

 $ sudo yum install java-1.8.0-openjdk-devel 

Step 3: Download JBoss Application Server

Go to the official JBoss website (https://www.jboss.org) and download the desired version of JBoss application server. Once downloaded, navigate to the directory where the file is located using the terminal.

Step 4: Extract JBoss Archive

Unzip the downloaded JBoss archive using the following command:

 $ tar xf jboss-x.x.x.Final.tar.gz 

Step 5: Set JBOSS_HOME Environment Variable

Set the JBOSS_HOME environment variable to the extracted JBoss directory. This can be done by editing the .bashrc file:

 $ vi ~/.bashrc 

Add the following line at the end of the file:

 export JBOSS_HOME=/path/to/jboss/directory 

Save and exit the file. Then, execute the following command to apply the changes:

 $ source ~/.bashrc 

Step 6: Start JBoss

Go to the JBoss bin directory using the terminal:

 $ cd $JBOSS_HOME/bin 

Launch JBoss by running the following command:

 $ ./standalone.sh 

After a successful start, you should see the JBoss server log and the message indicating that the server has started.

Step 7: Access JBoss Admin Console

To access the JBoss Admin Console, open a web browser and enter the following URL:

 http://localhost:8080 

You will be prompted for a username and password. The default login credentials are:

 Username: admin Password: admin 

Once logged in, you can manage and configure your JBoss application server through the Admin Console.

Congratulations! You have successfully installed JBoss on CentOS 7. You can now start deploying and running your Java applications using the powerful features provided by JBoss.
