config.json

Although you can use command-line to specify the parameters. A config file is a better choice.

{
  "taskdb": "mysql+taskdb://username:password@host:port/taskdb",
  "projectdb": "mysql+projectdb://username:password@host:port/projectdb",
  "resultdb": "mysql+resultdb://username:password@host:port/resultdb",
  "message_queue": "amqp://username:password@host:port/%2F",
  "webui": {
    "username": "some_name",
    "password": "some_passwd",
    "need-auth": true
  }
}

Database Connection URI type: should be one of `taskdb`, `projectdb`, `resultdb`.

running

You should run components alone with subcommands. You may add & after command to make it running in background and use screen or nohup to prevent exit after your ssh session ends. It's recommended to manage components with Supervisor.

# start **only one** scheduler instance
pyspider -c config.json scheduler

# phantomjs
pyspider -c config.json phantomjs

# start fetcher / processor / result_worker instances as many as your needs
pyspider -c config.json --phantomjs-proxy="localhost:25555" fetcher
pyspider -c config.json processor
pyspider -c config.json result_worker

# start webui, set `--scheduler-rpc` if scheduler is not running on the same host as webui
pyspider -c config.json webui

you can get complete options by running pyspider --help and pyspider webui --help for subcommands. 

"webui" in JSON is configs for subcommands. You can add parameters for other components similar to this one.

To deploy pyspider components in each single processes, you need at least one database service. pyspider now supports MySQL, MongoDB and PostgreSQL. You can choose one of them.

And you need a message queue service to connect the components together. You can use RabbitMQ, Beanstalk or Redis as message queue.

pip install --allow-all-external pyspider[all]

Even if you had install pyspider using pip before. Install with pyspider[all] is necessary to install the requirements for MySQL/MongoDB/RabbitMQ
