Synchrony does not start automatically upon reboot on the Confluence Data Center

[Bojan Kalicanin]

After provisioning Confluence Data Center, and installing Synchrony as a service I have noticed that it does not start when synchrony service has not been stopped explicitly. This happens eg. upon synchrony server reboot.

Cause:

Orphaned synchrony.pid file has not been cleaned and it is preventing service start upon reboot.

Solution:

To give the robustness to synchrony service, I have added couple of lines, which cleans up orphaned pid file when it is detected that synchrony has not been running.

#!/bin/bash

## CUSTOM VARIABLES - BEGIN
PIDFILE='/opt/atlassian/synchrony/synchrony.pid'
DAEMON='synchro+'

## CUSTOM VARIABLES - END

# Synchrony Linux service controller script
cd "/opt/atlassian/synchrony"

case "$1" in
start)

## CUSTOM PART - BEGIN
## Remove orphaned PID file, upon reboot, if synchrony service not already running
if [ $(ps -ef | grep $DAEMON | grep -v grep | wc -l) -ne 1 ] \
&& [ -f $PIDFILE ]
then
rm -f $PIDFILE
fi

## CUSTOM PART - END
