Initial Setup In Lumen

• run composer install to install all the important packages, (can be viewed in composer.json).

• run composer dump-autoload.

• run php artisan migrate.

• Install PHPRedis a PHP extension for Redis from https://github.com/phpredis/phpredis.

• In config/database.php there are following configurations that can be configured for redis.

  • host => IP Address of server where Redis is running.
  • port => Port of server where Redis is running. (By default Redis run on 6379 port)
  • database => Instance to use as database on Redis.
  • password => If password for Redis server is set, then set it's value.
  • read_timeout => Timeout Redis will honor before abandoning lookup for a request in store.
  • token_timeout => Timeout for user device information to stay in Redis store.
  • token_expiry_threshold => Message API will look for this value to decide whether token_timeout for the device shoud be updated or not.

• In config/push_notification.php following configurations are available for FCM and APNS.

  • apns.certificate_path => by default set to look for APNS generated certificate in StoragePath/certificates.
  • pass_phrase => Generated by APNS alongwith certificate.
  • fcm.api_key => Generated via FCM.

• API will automatically decide whether to choose sandbox URI of APNS or production based on DEBUG value in env.

• Set QUEUE_DRIVER=redis in .env file

• Setup Redis

  • run wget http://download.redis.io/redis-stable.tar.gz
  • run tar xvzf redis-stable.tar.gz
  • cd redis-stable
  • make
  • Change redis.conf for listening to different port or password protecting it or listening to different IP.

• Run Redis

  • cd redis-stable/src
  • run ./redis-server (Redis server is now up).
  • run ./redis-cli (Optional if you want to check redis functionality on CLI otherwise not required).

• Install and configure Supervisor (A process control system) from http://supervisord.org/installing.html.

• Configure Supervisor to run following command PHP artisan queue:listen --tries=3 so that if for some reason queues are stopped they are automatically restarted by Supervisor otherwise new push notifications won't be delivered to user.

• Supervisor configuration

  • Create laravel_worker.conf inside "/etc/supervisor/conf.d/" directory because supervisor listens to this directory by default for new configurations files (For further confirmation check [include] portion in supervisor configuration).
  • Contents of laravel_worker.conf

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /home/gostrive-dev/strive-admin/artisan queue:work redis --sleep=3 --tries=3 --daemon
autostart=true
autorestart=true
user=gostrive-dev
numprocs=8
redirect_stderr=true
stdout_logfile=/home/gostrive-dev/strive-admin/storage/logs/worker.log

• After creating laravel_worker.conf run following commands

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-worker:*
