Use PostgreSQL as Celery backend

1. Installing PostgreSQL, Memcached.

   $ sudo apt-get install postgresql memcached
   $ sudo su - postgres
   $ psql
   postgres=# CREATE USER pgraph WITH PASSWORD 'passw0rd';
   postgres=# CREATE DATABASE pgraph OWNER pgraph;
   postgres=# \q
   

   Note

   You can use yrmcds instead of memcached.:

   $ sudo apt-get install yrmcds
   

2. Cloning repository, and add remote repository.

   $ git clone https://github.com/mkouhei/pgraph
   $ cd pgraph
   

3. Generate requirements.txt.

   $ python -m venv /path/to/heroku-venv
   $ . /path/to/heroku-venv
   $ pip install -e . -e .[heroku]
   

4. Running celery worker.

   $ DATABSE_URL=postgres://pgraph:passw0rd@locahost:5432/pgraph CONFIG_FILE=heroku.ini newrelic-admin run-program celery worker -c 1 -A pgraph.tasks --loglevel=info
   

5. Execute run script.

   $ DATABASE_URL=postgres://pgraph:passw0rd@localhost:5432/pgraph MEMCACHEDCLOUD_SERVERS=127.0.0.1:11211 newrelic-admin run-program sh run
   

Use RabbigMQ as Celery backend

1. Installing RabbitMQ, Memcached.

   $ sudo apt-get install rabbitmq-server memcached

   $ sudo apt-get install yrmcds
   

2. Cloning repository, and add remote repository.

   $ git clone https://github.com/mkouhei/pgraph
   $ cd pgraph
   

3. Generate requirements.txt.

   $ python setup.py --version
   $ pip install -e . -e .[heroku]
   

4. Running celery worker.

   $ CONFIG_FILE=heroku.ini newrelic-admin run-program celery worker -c 1 -A pgraph.tasks --loglevel=info
   

5. Execute run script.

   $ MEMCACHEDCLOUD_SERVERS=127.0.0.1:11211 newrelic-admin run-program sh run
