Working with Essential Red Hat Linux System Administration Tools - yum

In this lab we are going to make sure we have the minimum knowledge we need in order to successfully pass the RHCE on RHEL8. In this lab we'll cover `yum/dnf` and the new Application Stream module. Since this is a new tool with RHEL8 it's normal to not understand it 100%, but this lab will help reinforce how to use the Application Stream. *This course is not approved or sponsored by Red Hat.*

  1. Challenge

    Install PostgreSQL Version 9.6

    If you run yum module list you'll note that postgresql 10 has a [e] next to it, indicating it's installed.

    Since our task is to install postgresql 9.6 we need to fix that. Note that yum and dnf are interchangeable commands:

    dnf remove postgresql
dnf module reset postgresql
dnf module enable postgresql:9.6
dnf install postgresql

    Those commands will remove the installed postgresql-10, reset the application stream, set the correct version for the application stream, and then install the correct version of postgresql.

  2. Challenge

    Install httpd

    While Apache does have an Application Stream, there aren't multiple versions. On top of that, our task doesn't specify a version anyway.

    So it's easy to just yum -y install httpd and call it done.
