In this article, we will see how to install Supervisor on AWS Elastic Beanstalk with Laravel.
Prerequisites:
• I assume you deployed your Laravel project on AWS Elastic Beanstalk & make all configurations of queue & etc.
• Connect to SSH.
• I'm using Amazon Linux 2 (Nginx server).
• PHP 7.4 installed on AWS.
After connect to ssh follow these steps:
Step 1: Install EPEL
The EPEL repository is an additional package repository that provides easy access to install packages for commonly used software.
$ sudo amazon-linux-extras install epel
Step 2: Install supervisor
Let's install supervisor run the following command.
$ sudo yum install -y supervisor
Step 3: Edit configuration file
Go to the default configuration file.
$ sudo vim /etc/supervisord.conf
Change the include directory at the end to:
files = supervisord.d/*.conf
Step 4: Create new files
Add a new configuration file. If the directory doesn’t exist, then make one.
$ sudo vim /etc/supervisord.d/NameYouLike.conf
Give the setting:
[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /var/app/current/artisan queue:work sqs --sleep=3 --tries=3 --max-time=3600
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
user=root
numprocs=8
redirect_stderr=true
stdout_logfile=/var/app/current/storage/worker.log
stopwaitsecs=3600
Note ⭕️
In command line, I'm using SQS for the queue, if you are using (Database or Redis) you should change it to the thing that you are using.
Step 5: Launch Supervisor
$ sudo supervisord -c /etc/supervisord.conf
Step 6: Apply The Changes
Apply new setting and check the status
$ sudo supervisorctl update;
$ sudo supervisorctl status
You should see something like that:
Step 7: Automatic start after system reboot
- Add a new configuration of restart Supervisor
$ sudo vim /etc/init.d/supervisord
Give this settings inside the file:

Does this has to be done everytime EB updates or is it like a one time process?
