In this article, we will review how to install WebSphere on RHEL9. It will include step-by-step instructions, prerequisites to ensure a smooth installation process, and insights into configuring WebSphere for optimal performance on Red Hat Enterprise Linux 9.
WebSphere, developed by IBM, is a robust and widely used application server that provides a stable platform for deploying and managing Java-based applications. In this guide, we’ll walk you through the step-by-step process of installing and configuring WebSphere on Red Hat Enterprise Linux 9 (RHEL 9) or CentOS 9. By following these instructions, you’ll have a fully operational WebSphere environment ready to host your Java applications.
Before you begin the installation process, ensure that you have the following prerequisites in place:
IBMid: We will assume that you already have an IBMid account. If not, you will need to create on before proceeding with this tutorial.
Operating System: RHEL 9 or CentOS 9 installed on your server.
Java Development Kit (JDK): WebSphere requires a Java runtime environment. Install the JDK by running the following command:
$ sudo dnf install java-11-openjdk-devel
The install will take a few minutes as there are over 170+ packages required to install Java-11-openjdk devel on a basic server instance.
[admin@ws-1 ~]$ sudo dnf install java-11-openjdk-devel

System Requirements: Check and ensure that your server meets the hardware and software requirements specified by IBM for WebSphere.
- Ensure your machine has 4GB of RAM and 2 cores
- 20GB of storage allocated to /opt or install path.
IBM Installation Manager: Download and install the IBM Installation Manager, which is used to install WebSphere. You can get it from the official IBM website.
Forward X11 to your server as the root user by running the following command:

At the Install Packages window, you will be presented with various software packages to choose from. Here are a few of the selections available:
Application Client for IBM WebSphere Application Server
DMZ Secure Proxy Server for IBM WebSphere Application Server
IBM HTTP Server for IBM WebSphere Application Server
IBM WebSphere Application Server for Liberty Network Deployment
For the demonstration purposes, we chose the DMZ Secure Proxy Server option for install. Your selection will be determined by what suits your environment.

NOTE: Depending on your software selection, you may also be prompted to provide your hostname and port number. We chose to go with the defaults.

Check the network configuration of your server. Ensure that necessary ports are open for WebSphere communication. WebSphere typically uses ports like 9060 for HTTP, 9043 for HTTPS, and additional ports for various services.
Run the following command(s) on your machine to ensure ports 2809 and 9060 (console) are open:
[root@ws-1 opt ]# firewall-cmd --permanent --add-port=2809/tcp --add-port=9060/tcp
success
[root@ws-1 opt]# firewall-cmd --reload
success
Repeat the commands (above) for any subsequent ports as needed.
[root@ws-1 opt]# firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
interfaces: eth0 eth1
sources:

ports: 2809/tcp 9060/tcp
protocols:
forward: yes

Run the firewall-cmd --list-all command to verify settings.
The remainder of this process is straightforward and self-explanatory. Accept license agreements and ensure you have sufficient disk space and system resources (e.g RAM, cores) for the software package you want to install.

Upon completion, the WebSphere Application server is ready for the final step which involves setting up profiles and customizing according to your specific requirements. The following section provides some basic examples that you can modify as needed to suit your needs.
Photo by admingeek from Infotechys
Here’s an example you might use to start the WebSphere Installation with a profile template:
/opt/IBM/WebSphere/AppServer/bin/manageprofiles.sh -create -templatePath /opt/IBM/WebSphere/AppServer/profileTemplates/default -profileName AppSrv01
Here’s what a sample.xml file residing under /opt/IBM/WebSphere/AppServer/profileTemplates/default looks like (below)
<server>
<!-- Define the server name -->
<serverName>MyServer</serverName>
<!-- Define the node name -->
<nodeName>MyNode</nodeName>
<!-- Define the host name -->
<hostName>localhost</hostName>
<!-- Define the port number -->
<serverPort>9080</serverPort>
<!-- Define the admin console port number -->
<adminPort>9060</adminPort>
<!-- Define the JVM settings -->
<jvmEntries xmi:id="JavaVirtualMachine_1" verboseModeClass="false" verboseModeGarbageCollection="false">
<classpath>${BOOTCLASSPATH}${PATH_SEPARATOR}${USER_INSTALL_ROOT}/lib/bootstrap.jar${PATH_SEPARATOR}${USER_INSTALL_ROOT}/lib/j2ee.jar${PATH_SEPARATOR}${USER_INSTALL_ROOT}/lib/lmproxy.jar${PATH_SEPARATOR}${USER_INSTALL_ROOT}/lib/urlprotocols.jar</classpath>
<initialHeapSize>512</initialHeapSize>
<maximumHeapSize>1024</maximumHeapSize>
</jvmEntries>
<!-- Define data source configurations -->
<dataSource xmi:id="DataSource_1" jdbcDriverRef="Derby Embedded JDBC Driver" jndiName="jdbc/MyDataSource">
<statementCacheSize>100</statementCacheSize>
<isolated>false</isolated>
<logMissingTransactionContext>false</logMissingTransactionContext>
</dataSource>
<!-- Define additional configurations -->
<!-- Add more configurations as needed -->
</server>
This XML snippet represents a simplified server profile configuration. Here’s a breakdown of the key elements:
serverName: Specifies the name of the server.nodeName: Specifies the name of the node where the server resides.hostName: Specifies the host name or IP address of the server.serverPort: Specifies the port number on which the server listens for incoming requests.adminPort: Specifies the port number for accessing the administrative console.jvmEntries: Defines Java Virtual Machine (JVM) settings such as initial and maximum heap sizes.dataSource: Defines a data source configuration, including JDBC driver reference and JNDI name.Additional configurations: You can add more elements to define other aspects of the server configuration, such as security settings, application mappings, and resource environment entries.
This profile template serves as a basis for creating server profiles in WebSphere. You can customize it further according to your specific application requirements and deployment environment.
/opt/IBM/WebSphere/AppServer/bin/startServer.sh server1
Replace server1 with the actual name of your server instance.
/opt/IBM/WebSphere/AppServer/bin/stopServer.sh server1
This command gracefully shuts down the WebSphere Application Server.
Open a web browser and navigate to http://localhost:9060/ibm/console. Log in with the credentials you specified during installation.
WebSphere Console Navigation:
Deploy Applications via WebSphere Console:
/opt/IBM/WebSphere/AppServer/bin/wsadmin.sh -lang jython -c "AdminApp.install('/path/to/your/application.ear', '[ -appname YourAppName -MapWebModToVH [[.* .* default_host]]]')"
Adjust the path to your application and set the desired application name.
