Can't start thin server from bash script - ruby-on-rails

I'm trying to start my Rails app with thin from the shell script. If I run the commands manually, everything works fine, but if I run the script, it just won't work.
#!/bin/bash
cd /path/to/my/project_1
thin -e production -p 3000 --daemonize -s 10 start
cd /path/to/my/project_2
thin -e production -p 3010 --daemonize -s 10 start
What am I doing wrong? Thanks.

This question was solved in the comments, but for posterity’s sake:
Make sure you have execute permission on the script. chmod 755 my_awesome_script ought to do it.

reboot script to start rails server

My rails server is running under a deployer user and I normally start it like this
#restart.sh
#!/bin/bash
sudo -u deployer -H bash -l
cd /var/www/html/cms/
./server -e staging start
So when I login over SSH i run ./restart.sh and that works great.
I'm trying to do this automatically after a reboot so I've added a reboot_site.service in
/etc/systemd/system/reboot_site.service
# /etc/systemd/system/reboot_site.service
[Unit]
Description=reboot_site
After=syslog.target network.target
[Service]
Type=simple
WorkingDirectory=/var/www/html/cms
# If you use rbenv:
# ExecStart=/bin/bash -lc '/home/deploy/.rbenv/shims/bundle exec sidekiq -e production'
# If you use the system's ruby:
ExecStart=/home/ec2-user/restart.sh
[Install]
WantedBy=multi-user.target
The service is enabled using sudo systemctl enable reboot_site.service
However when I now reboot the server the script stops execution after the following line
sudo -u deployer -H bash -l
Server is an AWS EC2 AIM instance
What's wrong with my configuration to make this work and how can I fix this?
It stops on sudo -u deployer -H bash -l because your script just changes user and will not continue until you logout as this user. So the remaining commands in your script are not executed.
I would suggest the following version which uses runuser:
#!/bin/bash
runuser -l deployer -c 'cd /var/www/html/cms/ && ./server -e staging start'
if you just need to run a script on startup you can configure a crontab for this
#crontab -e
#reboot /home/ec2-user/restart.sh

How can I run puma server on boot instead of crontab

I wonder what's the better practice to run rails server with Puma and nginx on reboot.
because my crontab doesn't work.
I want to learn how to run the server automatically in other ways
PATH=/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/home/userA/bin:/home/userA/.rbenv/shims:/home/userA/.rbenv/bin:/home/userA/.rbenv$
SHELL=/usr/bin/zsh
#reboot zsh -l -c 'cd /project && bundle exec puma config/puma.rb'

How to start passenger production when ubuntu or server starts?

I developed a Ruby On Rails application and want to deploy in production (intranet).
As of now i created an sh file to run the passenger like so:
cd /pathofmyapp
passenger start -a 0.0.0.0 -p 3000 -d -e production
cd /pathofmyapp2
passenger start -a 0.0.0.0 -p 3000 -d -e production
When the ubuntu server starts i have to execute the sh or manually start the passenger.
Is their a way to automate this so that whenever the ubuntu server starts, the command will automatically run or the ruby on rails application will start?
Thanks in advance.
You can add that to your cronjob to run the code on reboot.
#reboot cd /pathofmyapp && passenger start -a 0.0.0.0 -d -e production

rvmsudo unicorn_rails -c config/unicorn/production.rb -D --env production is not working

I have installed new ec2-instance for production server
when i tried the following command in the current folder
[ec2-user#ip-xx-xxx-xxx-xxx current]$ rvmsudo unicorn_rails -c config/unicorn/production.rb
-D --env production
sudo: unicorn_rails: command not found
Please let me know how to start the production server which is running at port 80.
Thanks in advance
For port 80: First run
export rvmsudo_secure_path=1
then
rvmsudo unicorn_rails -c config/unicorn/production.rb -D --env production
it will work for sure
You dont have to use rvmsudo and all to start your unicorn app server. You can do it
bundle exec unicorn -D -c /path/to/app/unicorn.rb -E production

start unicorn app server when the ubuntu server starts

I am running my rails application using ruby enterprise edition with unicorn as app server. I run this command
bundle exec unicorn -D -c /home/ubuntu/apps/st/config/unicorn.rb
I need to run this command soon after the system reboots or starts. I am running the app on ubuntu 10.04 LTS EC2 instance. I tried couple of examples which are mentioned on this site as well as this site but it’s not working for me. Any heads up
Try it as an Upstart. To do so, you need to create a myapp.conf file into the directory /etc/init/ with the contents below:
description "myapp server"
start on runlevel [23]
stop on shutdown
exec sudo -u myuser sh -c "cd /path/to/my/app && bundle exec unicorn -D -c /home/ubuntu/apps/st/config/unicorn.rb"
respawn
After that, you should be able to start/stop/restart your app with the commands below:
start myapp
stop myapp
restart myapp
Use ps -aux | grep myapp to check if your app is running.
You can use this file as a template, set appropriate paths mentioned in this file, make it executable and symlink into /etc/init.d/my_unicorn_server. Now you can start the server using:
sudo service my_unicorn_server start
Then you can do:
sudo update-rc.d my_unicorn_server defaults
To startup the unicorn server on system reboot automatically.
In my case, I just wanted it quick so I place the startup command in /etc/rc.local like below. Note that i'm using RVM.
# By default this script does nothing.
cd <your project dir>
/usr/local/rvm/gems/ruby-2.2.1/wrappers/bundle exec unicorn -c <your project dir>/config/unicorn.conf -D
test -e /etc/ssh/ssh_host_dsa_key || dpkg-reconfigure openssh-server
exit 0
Make sure your startup command is above the exit 0. After you reboot, check whether it is running or not by directly hitting the url of your application or use ps -aux | grep unicorn command.
Note* Previously I use Phusion Passenger but I'm having trouble to see its error log, so I move back to unicorn. I also tried #warantesbr without success, which I guess it fails because my whole environment where setup using root access.
If you are using unicorn_init script
You can configure a cron job to start the unicorn server on reboot
crontab -e
and add
#reboot /bin/bash -l -c 'service unicorn_<your service name> start >> /<path to log file>/cron.log 2>&1'
