Installing Additional Packages

After login, you can install additional packages with 'yum':

  $ yum install gnome
  $ yum install openssh-server
  $ yum install warewulf
  $ yum --installroot /vnfs/warewulf install warewulf-node

and use it to keep your cAos Linux system updated with the latest versions of software packages (and other fun things):

  $ yum check-update 
  $ yum update 
  $ yum update 'openssh*'
  $ yum search 'openssh*'
  $ yum info 'openssh*'

NOTE: yum is capable of using wildcard characters when searching for packages, but the patterns should be protected from the shell: put single quotes (') around them. Also make note that the example about uses 'update', not 'upgrade' (because 'upgrade' is deprecated).

NOTE: To finish the gnome (and XFree86) installation in the yum example above you will have to execute some configuration commands for X (or if you did not do it during the installation):

  $ xf86config

or:

  $ Xconfigurator

or you can try this (but it may fail):

  $ X -configure
  $ mv /root/XF86Config.new /etc/X11/XF86Config

and then start up X windows:

  $ startx

and hopefully you will have a functional gnome desktop environment.
