Follow the sections below to run a WSO2 product as a Linux service:

Prerequisites

Install JDK 1.6.24 or later or 1.7.* and set up the JAVA_HOME environment variable. 

Setting up CARBON_HOME

Extract the WSO2 product to a preferred directory in your machine and set the environment variable CARBON_HOME to the extracted directory location.

Running the product as a Linux service

  1. To run the product as a service, create a startup script and add it to the boot sequence. The basic structure of the startup script has three parts (i.e., start, stop and restart) as follows:

    Given below is a sample startup script. <PRODUCT_HOME> can vary depending on the WSO2 product's directory.

    In the above script, the server is started as a user by the name user1 rather than the root user. For example, su -c "${startcmd}" user1 

  2. Add the script to /etc/init.d/ directory.

    If you want to keep the scripts in a location other than /etc/init.d/ folder, you can add a symbolic link to the script in /etc/init.d/ and keep the actual script in a separate location. Say your script name is prodserver and it is in /opt/WSO2/ folder, then the commands for adding a link to /etc/init.d/ is as follows:

    • Make executable: sudo chmod a+x /opt/WSO2/prodserver

    • Add a link to /etc/init.d/: sudo ln -snf /opt/WSO2/prodserver /etc/init.d/prodserver
  3. Install the startup script to respective runlevels using the command update-rc.d. For example, give the following command for the sample script shown in step1:


    The defaults option in the above command makes the service to start in runlevels 2,3,4 and 5 and to stop in runlevels 0,1 and 6.

    A runlevel is a mode of operation in Linux (or any Unix-style operating system). There are several runlevels in a Linux server and each of these runlevels is represented by a single digit integer. Each runlevel designates a different system configuration and allows access to a different combination of processes.

  4. You can now start, stop and restart the server using service <service name> {start|stop|restart} command. You will be prompted for the password of the user (or root) who was used to start the service.
