Hey,
I'm using a machine in aws and when the machine starts all the services are starting including postgresql(v9.6 , centos). However, when I check the service`s status I see that it is stopped but all the processes are up (ps -ef ) and the postmaster.pid file is exist with the pid of the postmaster.
The next part of code responsible for starting postgresql in redhat(/etc/init.d/postgresql) :
$SU -l postgres -c "$PGENGINE/postmaster -D '$PGDATA' ${PGOPTS} >>\"$PGLOG\" 2>&1 &"
sleep 2
pid=`head -n 1 "$PGDATA/postmaster.pid" 2>/dev/null`
if [ "x$pid" != x ]
then
success "$PSQL_START"
touch "$lockfile"
echo $pid > "$pidfile"
echo
else
failure "$PSQL_START"
echo
script_result=1
fi
It seems that the sleep 2 isnt enough time to start the processes and thats why the service shows that the instance is down while it is up. Does any one faced this type of issue ? I mean, I can increase the sleep , but I dont think that it is the perfect solution in this case.
