Installation and removal of packages is a core skill for anyone managing Linux distributions. During this activity, the student will work with the package manager and installation utilities **yum** and **rpm** to manage packages on Red Hat/CentOS Linux distributions.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Elinks Application Install and Available
An elinks rpm file is already downloaded, but can’t be installed because of missing dependencies.
In order to install the package successfully, you will need to deal with the dependencies. You can use the package manager to do that for you via:
sudo yum install /home/cloud_user/Downloads/elinks-0.12-0.37.pre6.el7.0.1.x86_64.rpmOptionally, adding
-yto the command (sudo yum -y install...) will skip prompting for the dependencies, and will just complete the install as though you’d said "yes" to everything.If you are able to install the application and dependencies successfully, the learning activity can be considered successfully completed.
Note:: The exact version in your activity may be different; this version was current as of the time this activity was created.
