1.3. Getting Access to Go Toolset

Go Toolset is an offering that is distributed as a part of the Red Hat Developer Tools content set, which is available to customers with deployments of Red Hat Enterprise Linux 7. In order to install Go Toolset, enable the Red Hat Developer Tools and Red Hat Software Collections repositories by using the Red Hat Subscription Management and add the Red Hat Developer Tools key to your system.

  1. Enable the rhel-7-variant-devtools-rpms repository:

    # subscription-manager repos --enable rhel-7-variant-devtools-rpms

    Replace variant with the Red Hat Enterprise Linux system variant (server or workstation).

    Note

    We recommend developers to use Red Hat Enterprise Linux Server for access to the widest range of development tools.

  2. Enable the rhel-variant-rhscl-8-rpms repository:

    # subscription-manager repos --enable rhel-variant-rhscl-8-rpms

    Replace variant with the Red Hat Enterprise Linux system variant (server or workstation).

  3. Add the Red Hat Developer Tools key to your system:

    # cd /etc/pki/rpm-gpg
    # wget -O RPM-GPG-KEY-redhat-devel https://www.redhat.com/security/data/a5787476.txt
    # rpm --import RPM-GPG-KEY-redhat-devel

Once the subscription is attached to the system, and repositories enabled you can install Red Hat Go Toolset as described in Section 1.4, “Installing Go Toolset”.

1.4. Installing Go Toolset

Go Toolset is distributed as a collection of RPM packages that can be installed, updated, uninstalled, and inspected by using the standard package management tools that are included in Red Hat Enterprise Linux. Note that a valid subscription that provides access to the Red Hat Developer Tools content set is required in order to install Go Toolset on your system. For detailed instructions on how to associate your system with an appropriate subscription and get access to Go Toolset, see Section 1.3, “Getting Access to Go Toolset”.

Important

Before installing Go Toolset, install all available Red Hat Enterprise Linux updates.

  1. To install all components that are included in Go Toolset, install the go-toolset-1.10 package:

    # yum install go-toolset-1.10

    This installs all development and debugging tools, and other dependent packages to the system.

  2. Create the Go language workspace directory and environment variable:

    $ mkdir -p workspace_dir
    $ echo 'export GOPATH=workspace_dir' >> $HOME/.bashrc
    $ source $HOME/.bashrc

    Select an appropriate value for the workspace_dir directory. A common choice is $HOME/go.

    If the GOPATH variable is not set, the go compiler uses the ~/go directory.
