Chapter 2. Installation

The Red Hat Software Collections content set is available to customers with Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 subscriptions listed at https://access.redhat.com/solutions/472793. For information on how to register your system with Red Hat Subscription Management (RHSM), see Using and Configuring Red Hat Subscription Manager. For detailed instructions on how to enable Red Hat Software Collections using RHSM, see Section 2.1.1, “Using Red Hat Subscription Management”.

Since Red Hat Software Collections 2.2, the Red Hat Software Collections and Red Hat Developer Toolset content is available also in the ISO format at https://access.redhat.com/downloads, specifically for Server and Workstation. Note that packages that require the Optional channel, which are listed in Section 2.1.2, “Packages from the Optional Channel”, cannot be installed from the ISO image.

Red Hat Software Collections is distributed as a collection of RPM packages that can be installed, updated, and uninstalled by using the standard package management tools included in Red Hat Enterprise Linux. Note that a valid subscription is required to install Red Hat Software Collections on your system. For detailed instructions on how to associate your system with an appropriate subscription and get access to Red Hat Software Collections, see Section 2.1, “Getting Access to Red Hat Software Collections”.

Use of Red Hat Software Collections 3.3 requires the removal of any earlier pre-release versions, including Beta releases. If you have installed any previous version of Red Hat Software Collections 3.3, uninstall it from your system and install the new version as described in the Section 2.3, “Uninstalling Red Hat Software Collections” and Section 2.2.1, “Installing Individual Software Collections” sections.

The in-place upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7 is not supported by Red Hat Software Collections. As a consequence, the installed Software Collections might not work correctly after the upgrade. If you want to upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, it is strongly recommended to remove all Red Hat Software Collections packages, perform the in-place upgrade, update the Red Hat Software Collections repository, and install the Software Collections packages again. It is advisable to back up all data before upgrading.

yum install software_collection...

~]# yum install rh-php72 rh-mariadb102

yum list available software_collection-\*

yum install package_name...

~]# yum install rh-perl526-perl-CPAN rh-perl526-perl-Archive-Tar

debuginfo-install package_name

~]# debuginfo-install rh-ruby25-ruby

To uninstall any of the Software Collections components, type the following at a shell prompt as root:

yum remove software_collection\*

Replace software_collection with the Software Collection component you want to uninstall.

Note that uninstallation of the packages provided by Red Hat Software Collections does not affect the Red Hat Enterprise Linux system versions of these tools.

<collection>-build packages are not provided by default. If you wish to rebuild a collection and do not want or cannot use the rpmbuild --define 'scl foo' command, you first need to rebuild the metapackage, which provides the <collection>-build package.

Note that existing collections should not be rebuilt with different content. To add new packages into an existing collection, you need to create a new collection containing the new packages and make it dependent on packages from the original collection. The original collection has to be used without changes.

For detailed information on building Software Collections, refer to the Red Hat Software Collections Packaging Guide.
