Centos 7 custom bash script service does not work - bash

Question

I had created a deamon in centos 7 to send an email from email queue.
Email queue is implemented in Yii1. That works fine but when I tried to create and run daemon in server but it fails and shows an error :
echo "Error! Could not start MyStaging!"
I am following instructions which I found here.
On inspection I found that PID gets the value 1232 and pgrep -u $RUNAS -f $NAME > /dev/null command returns empty.
Below is my script:
#!/bin/bash
### BEGIN INIT INFO
# Provides: MyStaging
# Required-Start: $local_fs $network $named $time $syslog
# Required-Stop: $local_fs $network $named $time $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Description: This service having purpose to send email from email queue where relevant email push by particular module operation in queue.
### END INIT INFO
SCRIPT="/usr/bin/php5 /home/my/public_html/staging/protected/yiic mailqueue run"
RUNAS=root
NAME=MyStagingMailQueue
PIDFILE=/var/run/$NAME.pid
LOGFILE=/var/log/$NAME.log
start() {
if [ -f $PIDFILE ] && kill -0 $(cat $PIDFILE); then
echo 'Service already running' >&2
return 1
fi
echo 'Starting service ' >&2
local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!"
# su -s /bin/sh $RUNAS -c "$CMD" > "$PIDFILE"
# Try with this command line instead of above if not workable
su -c "$CMD" $RUNAS > "$PIDFILE"
sleep 2
PID=$(cat $PIDFILE)
if pgrep -u $RUNAS -f $NAME > /dev/null
then
echo "$NAME is now running, the PID is $PID"
else
echo "Error! Could not start $NAME!"
fi
}
stop() {
if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then
echo 'Service not running' >&2
return 1
fi
echo 'Stopping service ' >&2
kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"
echo 'Service stopped' >&2
}
status() {
printf "%-50s" "Checking $NAME..."
if [ -f $PIDFILE ]; then
PID=$(cat $PIDFILE)
if [ -z "$(ps axf | grep ${PID} | grep -v grep)" ]; then
printf "%s\n" "The process appears to be dead but pidfile still exists"
else
echo "Running, the PID is $PID"
fi
else
printf "%s\n" "Service not running"
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status
;;
restart)
stop
start
;;
*)
echo "Usage: $0 {start|stop|status|restart}"
esac
I don't know what is the issue. Please help me sort it out.

Since you're using CentOS 7, it's better to create a systemd service.
Step1:
Create a service file for your service say yiicmail.service. Do :
sudo touch /etc/systemd/system/yiicmail.service
Step2:
Open the the above file with your favourite editor and put the below content in it:
[Unit]
Description=yiic service
After=network.target
[Service]
Type=simple
User=root
ExecStart="/usr/bin/php5 /home/whizbite/public_html/staging/protected/yiic mailqueue run"
#If there are spaces, I would strings within quotes like above
Restart=on-abort
[Install]
WantedBy=multi-user.target
Step3:
Now it is the time to play with the service. To start it, do :
sudo systemctl start yiicmail # You don't have to type full name, that is, yiicmail.service
To check the status, do :
sudo systemctl status yiicmail
To stop it, do :
sudo systemctl stop yiicmail
To start the service at boot, do :
sudo systemctl enable yiicmail
To disable the service at boot, do:
sudo systemctl disable yiicmail
Hope this helps.
