Ready to install EWC? Here’s an overview of how to get your system up and running.
EWC is distributed as RPMs and Debs for RedHat/CentOS and Ubuntu Linux systems, and as Docker images. You can either use a script to automatically install and configure all components on a single system, or you can follow the manual instructions for your OS.
Here’s an overview of the options:
- One-line Install: Run our installation script for an opinionated install of all components on a single system. This is a our recommended way to get started. See the Quick Install section below for details.
- Manual Installation: Have custom needs? Maybe no Internet access from your servers? Or just don’t like using scripted installs? Read the manual installation instructions for your OS (Ubuntu 14/16, RHEL/CentOS 6, RHEL/CentOS 7), and adapt them to your needs. Here’s some additional guidance for setting up an internal mirror for the EWC repos.
- Ansible Playbooks: If you are an Ansible user, check these Ansible Playbooks for installing EWC. Ideal for repeatable, consistent, idempotent installation of EWC.
- High Availability Entrusting business critical automation tasks to a system like StackStorm leads to higher demands on that system. StackStorm can run in a HA mode to ensure these needs. EWC HA Cluster in Kubernetes - BETA automates entire complex infrastructure as a reproducible blueprint.
Choose the option that best suits your needs.
Upgrading to Extreme Workflow Composer? This is installed as a set of additional packages on top of StackStorm. You can either install StackStorm + Extreme Workflow Composer in one go, or add the Extreme Workflow Composer packages to an existing StackStorm system. If you are using Extreme Workflow Composer, you can also add Network Automation Suites. Read the Installing Extreme Workflow Composer documentation for more.
Grab a clean 64-bit Linux system that fits the system requirements. Make sure that
curl is up to date using
sudo apt-get install curl
on Ubuntu, or
sudo yum install curl nss on RHEL/CentOS. Then run this command:
curl -sSL https://stackstorm.com/packages/install.sh | bash -s -- --user=st2admin --password='Ch@ngeMe'
This is an opinionated installation of EWC. It will download and install all components, as per the single host reference deployment. It assumes that you have a clean, basic installation of Ubuntu or RHEL/CentOS.
If you are trying to install EWC on a server with other applications, or local customisations, you may run into problems. In that case, you should use one of the manual installation methods.
The script itself is not idempotent. If you try to re-run the script on top of a failed installation, it will fail. Start again with a clean system, or switch to a manual install.
If you’re installing behind a proxy, just export the proxy ENV variables
no_proxy before running the script.
export http_proxy=http://proxy.server.io:port export https_proxy=http://proxy.server.io:port export no_proxy=localhost,127.0.0.1
In case of MITM proxy, you may need to export additional
proxy_ca_bundle_path, see Installing Packs from Behind a Proxy.
If you have problems accessing the Web UI on a RHEL 7/CentOS 7 system, check the system firewall settings.
For security reasons, the installer script enables authentication and generates random passwords for dependent services such as MongoDB and PostgreSQL.
If for some reason (e.g. debugging), you need to access those services directly you can find
passwords in the config files -
/etc/st2/st2.conf for MongoDB and RabbitMQ password and
/etc/mistral/mistral.conf for PostgreSQL password.
