Cannot start AEM as a service on Ubuntu 18.04

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

Service file at /etc/systemd/system/aem.service (file permissions to "root")

[Unit]
Description=Adobe Experience Manager

[Service]
Type=simple
ExecStart=/usr/bin/aem start
ExecStop=/usr/bin/aem stop
ExecReload=/usr/bin/aem restart
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

when checking the service status:

ubuntu@ip-109:~$ sudo systemctl status aem 
aem.service - Adobe Experience Manager
Loaded: loaded (/etc/systemd/system/aem.service; enabled; vendor preset: enabled)

Oct 23 20:25:21 ip-172-31-14-109 su[20122]: pam_unix(su:session): session closed for user root

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. 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-8u 231-linux-x64.tar.gz"
  • 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 path to ".bashrc". Open to edit sudo nano ~/.bashrc
    • Add these lines to the end of the file:
      • export JAVA_HOME=/opt/java/jdk1.8.0_231
      • export PATH=${PATH}:${JAVA_HOME}/bin

After this.. start the "aem" service again. It should be working!
