Checking subscriptions and usage from the web interface

  • Click on the main “Admin” tab.
  • Click on “Software Channel Entitlements” in the left gray menu.
  • Go right
  • Click in the filter text entry form field
  • Type “core” into the filter form field
  • Click on the “go” button
  • Red Hat Enterprise Linux (core server) is the primary entitlement used for registering systems to the satellite or RHN. An equivalent number of “management” is needed entitlements to register a systems to the RHN Satellite server.
  • This column defines the total number of entitlements purchased. One “core server” entitlement is required for each Red Hat Enterprise Linux system in your environment.
  • This column defines the total number of entitlements used. As systems are registered or deleted from the RHN Satellite, this number will increment or decrease accordingly.

rho

  • DESCRIPTION
  • rho is a network discovery tool to identify the number of systems running on a network, their operating system, hardware, and release numbers for almost any Linux or Unix flavor. Being able to identify the systems running on the network is a vital component to managing licenses and renewals. Ultimately, discovery is part of the larger sysadmin task of managing inventories.
  • rho is also helpful for determining what revisions of RHEL should be made with channel-to-update

spacecmd

http://github.com/aparsons/spacecmd https://fedorahosted.org/spacewalk/wiki/spacecmd

Leveraging the RHN APIs and python, a command line utility named spacecmd has been developed to help with automation and administration of basic RHN Satellite functions. The spacecmd utility can be used within scripts and or crontab to automate entitlement reporting or other tasks. This package is open sourced and freely distributed under the GPLv3 license. To install the package, download the latest rpm from the project page on github.

Please note that this package is unsupported by Red Hat officially. Please post any problems or questions to the “issues” section on the github project page.

wget http://koji.spacewalkproject.org/spacewalk/whole/spacewalk-5E/spacewalk-5E-1.1/x86_64/os/Packages/spacecmd-0.5.1-1.el5.noarch.rpm rpm -ivh spacecmd*.rpm

cobbler boot iso with static IPs

Vlans

If the evironment does not have a dhcp server, or if the satellite server can not control dhcp, a cobbler boot ISO can handle kickstarts. Technically, this could also be accomplished by calling linux ks= from any RHEL/Centos/Fedora install disc, but the cobbler ISO allows booting various different versions and all of the distributions added to cobbler. However, a cobbler bootiso image will hard code a dhcp callout despite any attempts to use static in the kickstart profile because not using bootp/pxeos was only an afterthought with cobbler development. The only way around this problem is to use a system record and define Is static?.

  • Create kickstart profile Systems Kickstarts Kickstart Profiles Create
  • Add noipv6 to kernel options Systems Kickstarts Kickstart Profiles [select profile] Kickstart Details Details 1-kopts1
  • Uncheck networking Systems Kickstarts Kickstart Profiles [select profile] Kickstart Details Advanced Options 2-netopts
  • Create the cobbler system record and link to the kickstart profile cobbler system add –name=RHEL5-static-2 –profile=rhel5u5-staticIP:1:RedHatdeArgentinaSA
  • Add the default gateway and name server(s) to the system record cobbler system edit –name=RHEL5-static-2 –gateway=10.0.0.5 –name-servers=10.0.0.5
  • Add and interface and unique attributes (ip,subnet,dnsname,hostname, isstatic? ) cobbler system edit –name=RHEL5-static-2 –interface=eth0 –ip=10.0.0.180 –subnet=255.255.255.0
    –static=true –dns-name=RHEL5-static-2 –hostname=rhel5-static-2
  • Build a cobbler iso with the system record(s) cobbler buildiso –help cobbler buildiso –systems=RHEL5-static1,RHEL5-static-2 –profiles= –tempdir=/tmp/buildiso –iso=/tmp/kickstart-static.iso

The Satellite deployment guide defines a much more complicated way to build a bootable ISO …

Config Channels and remote scripts

Requirements

  • Provisioning entitlement
  • Activation key that enables configuration management and is subscribed to configuration channel(s)
  • A kickstart profile which is connected to a activation key and also has the enable remote commands and configuration management boxes checked.

Config channels

Satellite allows an administrator to define customized configuration files to ease deployment and maintain consistency throughout the organization. The files can be copied during kickstart or manually deployed post install. The files are versioned so that you can make changes and revert them if needed. In order to enable this functionality on your systems, you will need to install a few packages and execute a command …

yum install rhncfg*
rhn-actions-control --enable-all

Remote scripts

Remote scripts offer an alternative and centralized way to execute commands on one system or multiple via the system set manager. Remote scripts are enabled by the rhn-actions-control command and if you used –enable-all as directed in the configuration channel example, remote scripts will also be enabled. Remote scripts can be executed per system, group or by selected system sets in the system set manager.

Systems Activation Keys Keyname Activation-key-config-file-deploy

Enabling in a kickstart profile

  • Create or modify an activation key to enable file deployment per: Satellite
  • Ensure the three checkboxes shown below are checked
  • Activationkey-config-remote-1
  • Subscribe the activation key to the desired configuration channels
  • Activation-keys-config-remote-1.5
  • Create or modify a kickstart profile and check the following two boxes on the details tab
  • Activation-keys-config-remote-2
  • Connect the kickstart profile to the appropriate activation key
  • Activation-keys-config-remote-2.5
  • If everything up to this point has been configured correctly, the kickstart file should have the following commands above the registration section
  • Activation-keys-config-remote-3

rhnsd versus osad

A system checks in with your satellite or rhn at an interval defined in /etc/sysconfig/rhn/rhnsd (the default is 240 minutes or 4 hours). Any actions scheduled by the satellite will not complete or be queued until the system checks in. If you require the ability to schedule actions immediately on your systems, the osad package can be installed on a client system. Osad works similar to a message bus in which your scheduled actions can be completed in almost real time. No additonal configuration is required to use osad after being installed.

yum -y install osad
chkconfig osad on
service osad start

subversion: cobbler / bootstraps

If /var/lib/cobbler/snippets becomes a constant target for development, it should be properly versioned with either cvs, svn or git. The repository can be created on Satellite or on a different server. More generic SVN information: http://tannerjc.net/wiki/index.php?title=Subversion

Setup

yum -y install subversion svnadmin create /var/svn/repos/satellite-snippets svnadmin create /var/svn/repos/satellite-bootstrap chown -R apache.apache /var/svn/repos/satellite* Give websvn access to the repositories …

[root@sasha repos]# fgrep satellite /etc/websvn/config.php
$config-addRepository('satellite: snippets', 'file:///var/svn/repos/satellite-snippets');
$config-addRepository('satellite: bootstrap', 'file:///var/svn/repos/satellite-bootstrap');

First import

svn import –username jtanner –password ##### /var/lib/cobbler/snippets http://192.168.1.14/repos/satellite-snippets -m Initial import for satellite-snippets svn import –username jtanner –password ##### /var/www/html/pub/bootstrap http://192.168.1.14/repos/satellite-bootstrap -m Initial import for satellite-bootstrap
