bash script starting service over ssh - bash

I'm trying to start a service over ssh in a bash script that I just call from the command line. I can do the following commands: (I have ssh keys in place so I don't need to put a p/w in)
ssh -t -t user#server 'sudo /sbin/service test stop' -- Works fine, stops the service
ssh -t -t user#server 'sudo /sbin/service test status' -- Works fine, status's the service
ssh -t -t user#server 'sudo /sbin/service test start' -- Doesn't start the service ???
This is with a custom init.d script running on centos 6.7
Does anyone have any ideas?
or see what I might be missing?
Thanks!
EDIT: Here is the init.d script:
#!/bin/bash
#
### BEGIN INIT INFO
# Provides: test
# Required-Start: networking
# Required-Stop: networking
# Default-Start: 3 4 5
# Default-Stop: 0 1 6

RETVAL=$?
[ $RETVAL -eq 0 ] && {
touch $LOCKFILE
pidof $APPNAME > $PIDFILE
}
return $RETVAL
}
stop() {
echo -n $"Stopping $APPNAME:"
killproc -p "$PIDFILE" $APPNAME
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f $LOCKFILE $PIDFILE
return $RETVAL
}

;;
restart)
stop
start
;;
*)
echo "Usage $prg {start|stop|status|restart}"
exit 1
;;
esac
exit $RETVAL

I found a work around:
ssh -t -t user#server 'sudo bash -s' < '/tmp/start_test.sh'
and then on the server:
/tmp/start_test.sh
#!/bin/bash
sudo service test start >> /tmp/start.log
exit 0

I tested this one successfully:
echo "sudo service test start && exit" | python -c 'import pty, sys; pty.spawn(sys.argv[1:])' ssh user#server

How to start elasticsearch run as service in centos 7?

I have install elasticsearch 2.3.3 in centos 7 but after closing terminal elasticsearch plugin head automatically close but I want keep running in background. please give me helpful answer.
You can run it in background as two ways,
1. Nohup
2. Creating service script and put it in init.d folder
Nohup
Eg: nohup ./bin/elasticsearch
Service script
Use the following script,
#!/bin/bash

Centos 7 custom bash script service does not work

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

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.

Abstracting the CMD variable to a function fixed the issue.
As indirectly suggested by tripleee's resource shared.

Running Cassandra as a service on OpenSuse

I am trying to run Cassandra as a service on OpenSuse (Leap 42.1).
I have tried installing with apache-cassandra-2.1.11-bin.tar.gz and then copying /etc/init.d/cassandra from https://gist.github.com/sgomezvillamor/5458309. However, the startup script is not designed for OpenSuse, as the system.log says:
/etc/init.d/cassandra: line 30: daemon: command not found.
The problem would not exist if there would be an installer that would create the scripts correctly, similarly as there are for some other OSs. Searching for an installation package, I found http://www.datastax.com/dev/blog/announcing-rpms-cassandra and tried to look for an rpm in rpm.riptano.com but I cannot figure out which one would work in OpenSuse.
Which of those packages would work for OpenSuse? Or, how should I modify the startup script for Suse-fying it?
I would check these instructions which are for Cassandra 2.1: Installing DataStax Community 2.1 on RHEL-based systems.
I'm not sure whether that will get you 100% there on an OpenSUSE system, but should get you very close.
I got it to work with /etc/init.d/cassandra file:

Now (the script's name is uicorn_app)
sudo update-rc.d `unicorn_app` defaults
works. But whenever i try
$ sudo service unicorn_app start
Starting app
-su bundle: command not found
However i am able to stop it via
$ sudo service unicorn_app stop
after i started it manually with
RAILS_ENV=production rails s -b ip.ip.ip.ip
I installed ruby on rails on /etc/local via rbenv and the PATH
first entries redirect to the proper directories:
/usr/local/rbenv/shims
/usr/lcoal/rbenv/bin
What do i need to change that my scripts finds bundle? Since i think the PATH is correct what else could go wrong? Thanks in advance for help!
OK the solution was to do with the rbenv installation. I needed to add the lines PATH and RBENV_ROOT to my ~/.bash_profile. After adding them there i was able to start unicorn via sudo service unicorn_app start
