Add Packages

Run the command rpm -qa to list the packages that are installed at a host.

Search for packages with the command: apt-cache search <search_term>. Because the APT package cache is used there will be searched in the information of all available packages, not just the installed ones.

Install the packages at the nodes with the following steps at node vangogh0:

1. Add to the Cfengine configuration file
   /data/cfengine/vangogh/purge/etc/cfengine/cf_files/change_management/packages.cf
   below the lines packages: and any:: the following lines to install the packages:

   packages:
   	    any::
   	            <package> [<package> [...]]
   	                    action=install

2. Run the command: cfrun_nodes all -DCHANGE.
3. Uncomment the <package> [<package> [...]] and action=install lines. Otherwise the install commands will be rerun.

Install the packages at vangogh0 with the command: apt-get install <package> [<package> [...]].
