Answer 1

Installing Supervisor

sudo apt-get install supervisor

Configuring Supervisor

step 1 : goto /etc/supervisor/conf.d directory

cd /etc/supervisor/conf.d

step 2 : create a worker file laravel-worker.conf that will listen queue

sudo nano laravel-worker.conf

*Note : Now assuming that your laravel app is inside /var/www/html directory

project folder is : /var/www/html/LaravelApp

step 3 : paste below code in laravel-worker.conf and save file

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/html/LaravelApp/artisan queue:listen redis --queue=default --sleep=3 --tries=3 
autostart=true
autorestart=true
user=root
numprocs=8
redirect_stderr=true
stdout_logfile= /var/www/html/LaravelApp/storage/logs/worker.log

*Note : Here is assumed that you are using redis for queue connection

in .env file QUEUE_CONNECTION=redis

command=php /var/www/html/LaravelApp/artisan queue:listen redis

if you are using other connection then , general syntax will be :

command= php [project_folder_path]/artisan queue:listen [connection_name]

[connection_name] can be any of sync , database , beanstalkd , sqs , redis

step 4 : create a worker file laravel-schedule.conf that will run artisan schedule:run command at every 1 minute (60 seconds) (*you can change it as per your requirement)

[program:laravel-schedule]
process_name=%(program_name)s_%(process_num)02d
command=/bin/bash -c 'while true; do date && php /var/www/html/LaravelApp/artisan schedule:run; sleep 60; done'
autostart=true
autorestart=true
numprocs=1
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0

step 5 : Starting Supervisor : run below commands

sudo supervisorctl reread

sudo supervisorctl update

sudo supervisorctl start all

*Note : Whenever you make changes in any of configuration .conf files , run above commands of Step 5
