Axibase Time Series Database

Web Driver Installation

Overview

The database supports two types of web drivers: PhantomJS and Chrome. Web driver is a programmable browser that allows emulating user actions and capturing web pages as if there are displayed to a real user.

Linux Container

If you are installing the web driver in a Linux container, log in as root and install wget prior to switching to the axibase user.

docker exec -it -u root atsd bash
apt-get update && apt-get install wget
su axibase

  • Ensure that axibase user is allowed to execute the binary
ls -all /home/axibase | grep phantomjs-2.1.1-linux-x86_64
