Installing the Integration Control Plane

Follow the steps given below to install the Integration Control Plane (ICP).

Installing the Integration Control Plane

  1. Go to the WSO2 Integration Control Plane web page.

  2. Click Download.

  3. Provide the necessary details.

  4. Click Zip Archive to download the Integration Control Plane as a ZIP file.

  5. Extract the archive file to a dedicated directory for the Integration Control Plane, which will hereafter be referred to as <ICP_HOME>.

Info

To connect the MI servers with the ICP server, add the following configuration to the deployment.toml file (stored in the <MI_HOME>/conf/ folder) of each server instance.

[dashboard_config]
dashboard_url = "https://{hostname/ip}:{port}/dashboard/api/"
heartbeat_interval = 5
group_id = "mi_dev"
node_id = "dev_node_2"
For more information, see Configure the MI servers.

Setting up JAVA_HOME

You must set your JAVA_HOME environment variable to point to the directory where the Java Development Kit (JDK) is installed on the computer.

Info

Environment variables are global system variables accessible by all the processes running under the operating system.

On Linux/OS X
  1. In your home directory, open the BASHRC file (.bash_profile file on Mac) using editors such as vi, emacs, pico, or mcedit.
  2. Assuming you have JDK 11.0.x in your system, add the following two lines at the bottom of the file, replacing /usr/java/jdk-11.0.x with the actual directory where the JDK is installed.

    On Linux:
    export JAVA_HOME=/usr/java/jdk-11.0.x
    export PATH=${JAVA_HOME}/bin:${PATH}
    
    On OS X:
    export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/11.0.x.jdk/Contents/Home
    
  3. Save the file.

    Info

    If you do not know how to work with text editors in a Linux SSH session, run the following command: cat >> .bashrc. Paste the string from the clipboard and press "Ctrl+D."

  4. To verify that the JAVA_HOME variable is set correctly, execute the following command.

    On Linux:
    echo $JAVA_HOME
    
    On OS X:
    which java
    If the above command gives you a path like /usr/bin/java, then it is a symbolic link to the real location. To get the real location, run the following:
    ls -l `which java`
    

The system returns the JDK installation path.

On Solaris
  1. In your home directory, open the BASHRC file in your favorite text editor such as vi, emacs, pico, or mcedit.
  2. Assuming you have JDK 11.0.x in your system, add the following two lines at the bottom of the file, replacing /usr/java/jdk-11.0.x with the actual directory where the JDK is installed.

    export JAVA_HOME=/usr/java/jdk-11.0.x
    export PATH=${JAVA_HOME}/bin:${PATH}
    
  3. Save the file.

    Info

    If you do not know how to work with text editors in an SSH session, run the following command: cat >> .bashrc

    Paste the string from the clipboard and press "Ctrl+D."

  4. To verify that the JAVA_HOME variable is set correctly, execute the following command:

    echo $JAVA_HOME

  5. The system returns the JDK installation path.

On Windows

Typically, the JDK is installed in a directory under C:/Program Files/Java , such as C:/Program Files/Java/jdk-11.0.x. If you have multiple versions installed, choose the latest one, which you can find by sorting by date.

You set up JAVA_HOME using the System Properties, as described below. Alternatively, if you just want to set JAVA_HOME temporarily for the current command prompt window, set it at the command prompt.

Setting up JAVA_HOME using the system properties

  1. Right-click the My Computer icon on the desktop and click Properties.

  2. In the System Properties window, click the Advanced tab, and then click Environment Variables.

  3. Click New under System variables (for all users) or under User variables (just for the user who is currently logged in).

  4. Enter the following information:

    • In the Variable name field, enter: JAVA_HOME
    • In the Variable value field, enter the installation path of the Java Development Kit, such as: c:/Program Files/Java/jdk-11.0.x

The JAVA_HOME variable is now set and will apply to any subsequent command prompt windows you open. If you have existing command prompt windows running, you must close and reopen them for the JAVA_HOME variable to take effect, or manually set the JAVA_HOME variable in those command prompt windows as described in the next section. To verify that the JAVA_HOME variable is set correctly, open a command window (from the Start menu, click Run, and then type CMD and click Enter) and execute the following command:

set JAVA_HOME

The system returns the JDK installation path.

Setting system properties

If you need to set additional system properties when the server starts, you can take the following approach:

  • Set the properties from a script : Setting your system properties in the startup script is ideal because it ensures that you set the properties every time you start the server. To avoid having to modify the script each time you upgrade, the best approach is to create your startup script that wraps the WSO2 startup script and adds the properties you want to set, rather than editing the WSO2 startup script directly.

Info

When using SUSE Linux, it ignores /etc/resolv.conf and only looks at the /etc/hosts file. This means that the server will throw an exception on startup if you have not specified anything besides localhost. To avoid this error, add the following line above 127.0.0.1 localhost in the /etc/hosts file: <ip_address><machine_name> localhost.
