Installing Alces Clusterware

Available platforms

Alces Clusterware currently operates on the following platforms/distributions:

  • Enterprise Linux 7 distributions: RHEL, CentOS, Scientific Linux (el7)
  • Enterprise Linux 6 distributions: RHEL, CentOS, Scientific Linux (el6)
  • Ubuntu LTS 16.04 (Xenial Xerus) (ubuntu1604)

Prerequisites

The install scripts handle the installation of all required packages from your distribution and will install on a minimal base. For Enterprise Linux distributions installation of the @core and @base package groups is sufficient.

Basic Installation

Clusterware is a system-level package and must be installed by the root user.

  1. Become root.

    sudo -s

  2. Set the cw_DIST environment variable to match the distribution on which you are installing. Currently available options are el7, el6 and ubuntu1604:

    export cw_DIST=el7

  3. Invoke installation by piping output from curl to bash:

    curl -sL http://git.io/clusterware-installer | /bin/bash

    If you want to you can download the script first. You might want to do this if you want to inspect what it's going to do, or if you're nervous about it being truncated during download:

    curl -sL http://git.io/clusterware-installer > /tmp/bootstrap.sh
less /tmp/bootstrap.sh
bash /tmp/bootstrap.sh

  4. After installation, you can logout and login again in order to set up the appropriate shell configuration, or you can source the shell configuration manually:

    source /etc/profile.d/alces-clusterware.sh

Advanced installation parameters

Additional environment variables may be set to influence the installation process.

Build from upstream source

Set the cw_BUILD_fetch_handling variable to indicate that you want to build from upstream source code rather than installing prebuilt binaries for your distribution. Choose source to download and build components from upstream sources, or dist to use prebuilt binaries downloaded from Amazon S3.

export cw_BUILD_fetch_handling=source
curl -sL http://git.io/clusterware-installer | /bin/bash

Build from existing directory

Set the cw_BUILD_source_dir variable to point to an existing clone of the repository. If a clone isn't available in the path you specify the path will be used to house the downloaded code rather than the default /tmp/clusterware temporary directory.

cd /usr/src
git clone https://github.com/alces-software/clusterware
export cw_BUILD_source_dir=/usr/src/clusterware
/usr/src/clusterware/scripts/bootstrap

Build from an alternative branch

Set the cw_BUILD_source_branch variable with the name of the branch you wish to build. Defaults to master. e.g.:

export cw_BUILD_source_branch=0.1.0
curl -sL http://git.io/clusterware-installer | /bin/bash

Download source from an alternative URL

Set the cw_BUILD_source_url variable with the URL to a tarball of the Clusterware source code in tar.gz format. Defaults to https://github.com/alces-software/clusterware/archive/<branch>. e.g.:

export cw_BUILD_source_url=http://symphony-app.mgt.symphony.local/clusterware/clusterware.tar.gz
curl -sL http://symphony-app.mgt.symphony.local/clusterware/bootstrap | /bin/bash

Download binary dependencies from an alternative lcoation

Set the cw_BUILD_dist_url variable with a base URL for suitable tarballs. Defaults to https://s3-eu-west-1.amazonaws.com/packages.alces-software.com/clusterware/dist. e.g.:

export cw_BUILD_dist_url=http://symphony-app.mgt.symphony.local/clusterware/dist
export cw_BUILD_source_url=http://symphony-app.mgt.symphony.local/clusterware/clusterware.tar.gz
curl -sL http://symphony-app.mgt.symphony.local/clusterware/bootstrap | /bin/bash

Download public repository dependencies from an alternative lcoation

Set the cw_BUILD_repo_url variable with a base URL for suitable tarballs. Defaults to unset. e.g.:

export cw_BUILD_repo_url=http://symphony-app.mgt.symphony.local/clusterware
export cw_BUILD_dist_url=http://symphony-app.mgt.symphony.local/clusterware/dist
export cw_BUILD_source_url=http://symphony-app.mgt.symphony.local/clusterware/clusterware.tar.gz
curl -sL http://symphony-app.mgt.symphony.local/clusterware/bootstrap | /bin/bash

Install Alces Clusterware in an alternative location

Set the cw_BUILD_target_dir variable with the filesystem location for installation of Alces Clusterware. Defaults to /opt/clusterware. e.g.:

export cw_BUILD_target_dir=/opt/sw/cluster/clusterware
curl -sL http://git.io/clusterware-installer | /bin/bash
