安装
- 快速安装
$ bash -c "$(curl -s https://install.prediction.io/install.sh)" 若用MySQL,需事先创建好表和用户 CREATE DATABASE pio DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; GRANT ALL PRIVILEGES ON pio.* TO pio@localhost IDENTIFIED BY 'pio';
pio表
MySQL [pio]> show tables; +------------------------------+ | Tables_in_pio | +------------------------------+ | pio_meta_accesskeys | | pio_meta_apps | | pio_meta_channels | | pio_meta_engineinstances | | pio_meta_enginemanifests | | pio_meta_evaluationinstances | | pio_model_models | +------------------------------+
启动pio
