2.4.2. Running the JBoss ON Server as a Service

The JBoss ON server, storage node and agent can be managed and run as a SysV style init service on Red Hat Enterprise Linux using the following example:
  1. Create a initalization scipt /etc/init.d/jboss-on:
    #!/bin/sh
    #
    # Example Red Hat JBoss Operations Network init script
    #
    # chkconfig: - 95 20
    # description: Red Hat JBoss Operations Network rhqctl services
    # processname: standalone.sh
    #
    #
    # This is an example script that can be used with a SysV style 
    # init service which starts a JBoss ON server, storage node, and 
    # agent using the rhqctl script provided by the JBoss ON server 
    # installation.
    
    prog="`basename "$0"`"
    
    # If available, the following files will be sourced, in order, for 
    # configuration. This means that if the same value is defined in a later
    # file, it will override the one specified in an earlier one:
    #
    #   /etc/jboss-on.conf
    #   /etc/jboss-on/${prog}.conf
    #
    # The following environment variables can be defined:
    # 
    #   RHQ_HOME -- Defaults to /opt/jboss/jboss-on
    #   RHQ_SERVER_HOME -- Defaults to RHQ_HOME/jon-server-*
    #   RHQ_AGENT_HOME -- Defaults to RHQ_HOME/rhq-agent
    #   RHQ_JAVA_HOME -- Defaults to /usr
    #   RHQ_USER -- Defaults to jonadmin
    #
    
    # If available, source environment variables for the service
    # Global defaults/settings
    [ -r "/etc/jboss-on.conf" ] && . "/etc/jboss-on.conf"
    # Settings specific to this service
    [ -r "/etc/jboss-on/${prog}.conf" ] && . "/etc/jboss-on/${prog}.conf"
    
    # If not yet set, use some reasonable defaults:
    [ -z "${RHQ_HOME}" ] && RHQ_HOME='/opt/jboss/jboss-on'
    [ -z "${RHQ_SERVER_HOME}" ] && RHQ_SERVER_HOME="`eval echo "${RHQ_HOME}/jon-server-"*`"
    [ -z "${RHQ_AGENT_HOME}" ] && RHQ_AGENT_HOME="${RHQ_HOME}"'/rhq-agent'
    [ -z "${RHQ_JAVA_HOME}" ] && RHQ_JAVA_HOME='/usr'
    [ -z "${RHQ_USER}" ] && RHQ_USER=jonadmin
    
    # We have to export these variables so that they are available to child
    # processes.
    export RHQ_SERVER_HOME
    export RHQ_AGENT_HOME
    export RHQ_JAVA_HOME
    
    
    # This is a convenient function that invokes rhqctl
    rhqctl() {
        RHQCTL_SCRIPT="${RHQ_SERVER_HOME}/bin/rhqctl"
        [ ! -x "${RHQCTL_SCRIPT}" ] && {
            echo >&2 "${RHQCTL_SCRIPT}"' was not found or is not executable.'
            exit 2
        }
        if [ -n "${RHQ_USER}" -a "$(whoami)" != "${RHQ_USER}" ]; then
            CMD="su -m ${RHQ_USER} -c '\"${RHQCTL_SCRIPT}\" $@'"
        else
            CMD="\"${RHQCTL_SCRIPT}\" $@"
        fi
        eval ${CMD}
    }
    
    # We invoke rhqctl differently if start or stop is used so we need this
    # case statement to determine what should happen.
    case "$1" in
      start)
        # Because rhqctl is so chatty/verbose we redirect standard output to
        # null so we do not see it during system start and stop.
        # Additionally, we invoke it in the background as it can block for 
        # some time during start.
        rhqctl "$@" >/dev/null &
        ;;
      stop)
        # Because rhqctl is so chatty/verbose we redirect standard output to
        # null so we do not see it during system start and stop.
        rhqctl "$@" >/dev/null
        ;;
      *)
        # Assuming we are not starting or stopping, we will display complete
        # output.
        rhqctl "$@"
        ;;
    esac
    
  2. Change the permissions on the file so it can be executed:
    chmod +x /etc/init.d/jboss-on
  3. Add the initalization script to chkconfig:
    sudo chkconfig --add /etc/init.d/jboss-on
  4. To indicate that you intend for the script to run system startup and stop during shutdown:
    sudo chkconfig jboss-on on
  5. To override the default values for RHQ_HOME, RHQ_SERVER_HOME, RHQ_AGENT_HOME, RHQ_JAVA_HOME and RHQ_USER, create the service configuration file /etc/jboss-on.conf or /etc/jboss-on/<SERVICE NAME>.conf with your specific values:
    RHQ_HOME=/usr/share/jboss-on
    RHQ_USER=jbosson
