Installing Supervisor on Elastic Beanstalk - 2021 - Linux AMI 2 - Laravel Worker Setup

readme.md

• Create the following folder structure in your root project directory: .ebextensions/supervisor

• Place the supervisor.config under .ebextensions/

• Place the setup.sh under .ebextensions/supervisor/

• Run "chmod +x .ebextensions/supervisor/setup.sh"

• Place the supervisord.conf under .ebextensions/supervisor/

• Place the supervisor_laravel.conf under .ebextensions/supervisor/

Feel free to update the files according to your needs. You mostly will need to change the command inside the supervisor_laravel.conf file

If you want to check if the supervisor is running, connect to the instance and run "supervisorctl status". If you want stop/kill supervisor run "ps aux | grep "[/]usr/bin/supervisord", get the PID and then run "kill PID_NUMBER"

setup.sh

#!/bin/bash

# If you want to have more than one application, and in just one of them to run the supervisor, uncomment the lines below, 
# and add the env variable IS_WORKER as true in the EBS application you want the supervisor

#if [ "${IS_WORKER}" != "true" ]; then
#    echo "Not a worker. Set variable IS_WORKER=true to run supervisor on this instance"
#    exit 0
#fi

If someone is struggling with the error "/bin/sh: .ebextensions/supervisor/setup.sh: /bin/bash^M: bad interpreter: No such file or directory" is because you're uploading using eb deploy from windows and the ZIP file encodes newlines in windows format (CRLF), note the "^M" after "bash".

To fix that, I've added new commands to supervisor.config

container_commands:
    01_fix_script_permissions:
        command: "chmod +x .ebextensions/supervisor/setup.sh"
    02_fix_newlines_a:
        command: "sed -i 's/^M$//' .ebextensions/supervisor/setup.sh"
    02_fix_newlines_b:
        command: "sed -i $'s/\r$//' .ebextensions/supervisor/setup.sh"
    03_install_supervisor:
        command: ".ebextensions/supervisor/setup.sh"

The first command adds the execution bit to the file in case it doesn't have it. The second (both a and b) removes those windows newlines (sincerely I don't know wich one fixes it, but I've left both and it works).

Question about this three lines in setup.sh (31,32,33):

. /opt/elasticbeanstalk/deployment/env && cat .ebextensions/supervisor/supervisord.conf > /etc/supervisor/supervisord.conf
. /opt/elasticbeanstalk/deployment/env && cat .ebextensions/supervisor/supervisord.conf > /etc/supervisord.conf
. /opt/elasticbeanstalk/deployment/env && cat .ebextensions/supervisor/supervisor_laravel.conf > /etc/supervisor/conf.d/supervisor_laravel.conf

Why does all three start with . /opt/elasticbeanstalk/deployment/env && ?

I suppose they try to load the environment variables, but for what purpose? Is it neccessary?
It's throwing me an error (bash: shell: command not found) and I've removed that part (now all three start at cat ...) and works fine.

above all .ebextenstion files have succesfully deployed to beanstalk.But i no log files (supervisor_laravel.err.log, supervisor_laravel.out.log) have created .Is that permission problem ?? if so means how can i add permisssion commands ?

I deployed successfully but the sqs queue does not execute. I changed the command to command=/usr/bin/php /var/app/current/artisan queue:work sqs but to no avail

@fabioselau077 sorry I haven’t worked with sqs before. Can you maybe try removing the database keyword on the artisan queue:work?

and try adding in the ENV QUEUE_CONNECTION=sqs

With a recent AWS EBS instance, easy_install may not work. In that case, this modified script might help.

Is this working for you at the moment? I get the files and supervisord daemon to start initially, but it exists after a minute (the whole supervisord process)...

does anyone experienced having different SQS URL being use when supervisor process the SQS message? I think that the environment variables does not take effect.

Direct those logs to /var/log/php-fpm/www-error.log they will get sent to cloudwatch, then you can filter them out.

@adityar15 Super thank you! I needed this one since I upgraded my EBS platforms
