Configuring AEM as a Service on CentOS

This article details how to set up AEM as a service on CentOS/Linux

Step-by-step guide
Prerequisites:
You will need root access
Download these 2 files

1. Filename: aem
#!/bin/bash
#
# /etc/rc.d/init.d/aem6
#
#
# # of the file to the end of the tags section must begin with a #
# character. After the tags section, there should be a blank line.
# This keeps normal comments in the rest of the file from being
# mistaken for tags, should they happen to fit the pattern.>
#
# chkconfig: 35 85 15
# description: This service manages the Adobe Experience Manager java process.
# processname: aem6
# pidfile: /crx-quickstart/conf/cq.pid# Source function library.
. /etc/rc.d/init.d/functions

SCRIPT_NAME=`basename $0`
AEM_ROOT=/opt/aem6
AEM_USER=aem

########
BIN=${AEM_ROOT}/crx-quickstart/bin
START=${BIN}/start
STOP=${BIN}/stop
STATUS=”${BIN}/status”

case “$1” in
start)
echo -n “Starting AEM services: ”
su – ${AEM_USER} ${START}
touch /var/lock/subsys/$SCRIPT_NAME
;;
stop)
echo -n “Shutting down AEM services: ”
su – ${AEM_USER} ${STOP}
rm -f /var/lock/subsys/$SCRIPT_NAME
;;
status)
su – ${AEM_USER} ${STATUS}
;;
restart)
su – ${AEM_USER} ${STOP}
su – ${AEM_USER} ${START}
;;
reload)
;;
*)
echo “Usage: $SCRIPT_NAME {start|stop|status|reload}”
exit 1
;;
esac

2. Filename: aem.service
[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

3. Open aem script file and update the below

• AEM_ROOT (e.g: /mnt/crx is the root, where /mnt/crx/crx-quickstart is the full path)
• AEM_USER (e.g: aem)

4. SCP these files to the server
Copy aem to /usr/bin/aem
Example: From terminal on your desktop $ scp <filename> user@1.1.1.1:/usr/bin/aem
Copy aem.service to /etc/system.d/system/aem.system
Example: From terminal on your desktop $ scp <filename> user@1.1.1.1:/etc/system.d/system/aem.system

5. SSH to your server
ssh user@1.1.1.1

6. Give permissions to the files
sudo chmod u+rwx /usr/bin/aem
sudo chmod u+rwx /etc/system.d/system/aem.system

7. Update
cd /etc/system.d/system
systemctl enable aem.system
You can restart the server or run the below commands to start AEM. Make sure 

8. you run Pre-requisite Step 2 before running this command.

Commands to START, RESTART and STOP AEM

• Start AEM – sudo service aem start
• Restart AEM – sudo service aem restart
• Stop AEM – sudo service aem stop

Notes

• The example above was tested on CentOS 7
• AEM 6.3 version was used. Although the above process should work for AEM 6.x
