I'm happy to announce, that there are new Software Collections available for testing (sig-sclo). There are the following packages available in centos-sclo-rh-testing for CentOS 6 and CentOS 7: devtoolset-7 rh-mariadb102 rh-postgresql96 rh-mongodb34 For installing them, run: $ sudo yum install centos-release-scl-rh $ sudo yum-config-manager --enable centos-sclo-rh-testing $ sudo yum install <scl> Learn more about these packages and how to use them at: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/ https://www.softwarecollections.org/en/scls/rhscl/rh-mariadb102/ https://www.softwarecollections.org/en/scls/rhscl/rh-postgresql96/ https://www.softwarecollections.org/en/scls/rhscl/rh-mongodb34/ The three new databases also deliver packages called <scl>-syspaths, that put wrappers into standard paths, so users don't need to bother with the alternative path. More info available at: https://developers.redhat.com/blog/2017/10/18/use-software-collections-without-bothering-alternative-path/ All these collections are CentOS-based rebuilds built by SCLo SIG community, and the packages have been available in Red Hat Software Collections 3.0 for RHEL: https://access.redhat.com/documentation/en-us/red_hat_software_collections/3/html/3.0_release_notes/ So, for RHEL-based builds, follow the steps in the documentation above.
