### Queues Supervisor config

Config file path: **/etc/supervisor/conf.d/queue-worker-search-and-displace-ingest-production.conf**

```bash
[program:queue-worker-search-and-displace-ingest-production]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/html/searchanddisplace-ingest/artisan queue:listen --queue=sd_ingest,default --tries=2 --timeout=180
autostart=true
autorestart=true
user=www-data
numprocs=3
redirect_stderr=true
stdout_logfile=/var/log/queue/queue-worker-search-and-displace-ingest-production.log
```

The value for the **command** key should reflect the app path (in the example above the app's path is **/var/www/html/searchanddisplace-ingest**).

The **stdout_logfile** value is the log file. All parent directories must already exist. 

### Install app
- Download app

```
cd /var/www/html && \
git clone https://git.law/newroco/searchanddisplace-ingest.git && \
chown -R www-data:www-data searchanddisplace-ingest && \
cd searchanddisplace-ingest
```

- Install Dewarp
```
# Dewarp
cd /var/www/html/searchanddisplace-ingest/resources/python/dewarp && \
pip3 install opencv-python
```

- Install and configure app

```bash
# Generate environment file
cp .env.example .env

# Install backend packages
composer install

# Generate app key
php artisan key:generate

# Change in .env the value for the QUEUE_CONNECTION to redis, if it is not set already

# Deploy supervisor
supervisorctl reread
supervisorctl update
supervisorctl start all
```

- Check the queue worker is running

```
supervisorctl status
```
