I'm trying to setup AEM (Adobe Experience Manager) Author as a Service on Ubuntu 18.04 on an AWS EC2 instance.

Script file "aem" at `/usr/bin/aem` (file permissions to "root")

    #!/bin/bash

    #

    # description: This service manages the Adobe Experience Manager java process.

    # processname: aem6

    . /lib/lsb/init-functions

    SCRIPT_NAME=`basename $0`

    AEM_ROOT=/opt/aem/author

    AEM_USER=root

    ########

    BIN=${AEM_ROOT}/crx-quickstart/bin

    START=${BIN}/start

    STOP=${BIN}/stop

    STATUS=${BIN}/status

    case "$1" in

      start)

        if [ -f $START ]; then

           echo "Starting AEM Service.."

           /bin/su -l $AEM_USER -c $START

           RETVAL=$?

           [ $RETVAL -eq 0 ] && touch /var/lock/subsys/${SCRIPT_NAME}

        fi

       ;;

       stop)

        if [ -f $STOP ]; then

           echo "Stopping AEM Service.."

           /bin/su -l $AEM_USER -c $STOP

           RETVAL=$?

           [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/${SCRIPT_NAME}

        fi

        ;;

        status)

          if [ -f $STATUS ]; then

             echo -s "Checking status of $SCRIPT_NAME: "

             /bin/su -l $AEM_USER -c $STATUS

             RETVAL=$?

             [ $RETVAL -eq 0 ] && echo "$SCRIPT_NAME is running"

          fi

       ;;

       restart)

          /bin/su -l ${AEM_USER} -c ${STOP}

          /bin/su -l ${AEM_USER} -c ${START}

       ;;

       reload)

       ;;

       *)

         echo "Usage: $0 {start|stop|status|reload}"

         RETVAL=1

         ;;

    esac

    exit $RETVAL

But cannot see "java" process (using `ps -ef | grep java` ) or port "4502" being used (using `sudo lsof -i -P -n | grep LISTEN`).

What am i missing?

Was able to resolve the issue. the problem was with "java" not being available to all users. Earlier installed Oracle Java using default (ubuntu) user, while the aem script was running as root.

Steps to install custom Java.. not the Ubuntu default:

  • Download the tar.gz file "https://download.oracle.com/otn/java/jdk/8u231-b11/5b13a193868b4bf28bcb45c792fce896/jdk-8u231-linux-..."
  • Copy the file to the server using SCP
  • Make a directory `mkdir /opt/java`
  • Install and copy `sudo tar -zxf jdk-8u231-linux-x64.tar.gz -C /opt/java/`
  • Update your environment to allow Java for all users.. run this command `sudo update-alternatives --install /usr/bin/java java /opt/java/jdk1.8.0_231/bin/java 1`
  • Add the path to ".bashrc". Open to edit `sudo nano ~/.bashrc`
    • Add these lines at the end of the file..
      • `export JAVA_HOME=/opt/java/jdk1.8.0_231`
      • `export PATH=${PATH}:${JAVA_HOME}/bin`

After this, start "aem" service again. It should be running!

No.. nothing is being printed.

But i looked at all.. i found this under stdout.log

/opt/aem/author/crx-quickstart/bin/start: line 139: java: command not found

"java" is installed.. it is available to "ubuntu" (default) user, maybe not "root".
