Spacewalk Upgrade Instructions

These are upgrade instruction for upgrading Spacewalk 1.0 to Spacewalk 1.1.

These upgrade instruction apply to Spacewalk installations meeting the following criteria:

  • Spacewalk 1.0 running on Red Hat Enterprise Linux 5 Server or CentOS 5
  • Your Spacewalk uses Oracle 10g / Oracle-XE as a database backend

Spacewalk 0.8 to 1.0 upgrade instructions, are available at HowToUpgrade10


Spacewalk upgrade involves several basic steps:

  1. Configuration files and Spacewalk database backup
  2. Package upgrade
  3. Schema upgrade
  4. Upgrade of Spacewalk configuration
  5. Regenerate kickstart files
  6. Restart Spacewalk
  7. Update of monitoring setup
  8. Restart Spacewalk
  9. Rebuild search indexes

Assumptions

  • For RHEL or CentOS, you will need the Base, EPEL 5 repositories enabled for dependencies.
  • You had set up your yum to point to spacewalk 1.1 repository. For the repo setup specifics, see HowToInstall#SettingupSpacewalkrepo. Note, that with Spacewalk 1.1, the gpg key used to sign packages has been changed. New gpg key location is http://spacewalk.redhat.com/yum/RPM-GPG-KEY-spacewalk-2010

Database and configuration backup

  • For existing configuration files, create a backup of everything under /etc/sysconfig/rhn /etc/rhn and /etc/jabberd
  • Backup your ssl build directory, ordinarily /root/ssl-build
  • For instructions on how to create a backup of your existing Spacewalk database consult either Oracle documentation or contact your DBA

Package upgrade

Stop your Spacewalk by running:

# /usr/sbin/rhn-satellite stop

Perform package upgrade using yum:

# yum upgrade

During the upgrade, you may notice messages printed to the terminal when installing oracle-instantclient-selinux and spacewalk-selinux. These messages are produced by restorecon and do not pose any harm. On the contrary, these messages indicate relabeling of file system objects that is required for correct Spacewalk and SELinux symbiosis.

Check any .rpmnew/.rpmsave files that were created during the upgrade for you config files and make sure changes to your config files are preserved while new content from the distribution files is carried over.

# yum install rpmconf
# rpmconf -a

Schema upgrade

Make sure your Spacewalk server is down:

# /usr/sbin/rhn-satellite status

Make sure your oracle server is running (likely it isn't running since the earlier 'rhn-satellite stop' command stops the oracle-xe processes). For oracle-xe that would be:

# service oracle-xe status

If Oracle isn't running, start it

# service oracle-xe start

Run spacewalk-schema-upgrade script to upgrade database schema:

# /usr/bin/spacewalk-schema-upgrade

Log files from schema upgrade are being put into /var/log/spacewalk/schema-upgrade

Upgrade of Spacewalk configuration

For a successful upgrade, it is required to deploy configuration for cobbler and update configuration of apache SSL virtual host. Both steps can be accomplished by running:

# spacewalk-setup --disconnected --upgrade

You'll be asked by spacewalk-setup to provide your database connection information. This is the same information you provided to HowToInstall. Following this spacewalk-setup will ask you whether you wish to have your apache ssl configuration (/etc/httpd/conf.d/ssl.conf) updated by spacewalk-setup. You may choose to setup your ssl.conf manually, in which case you have to make sure you have the following directives present in your /etc/httpd/conf.d/ssl.conf:

# cat /etc/httpd/conf.d/ssl.conf
...
<VirtualHost _default_:443>
...
SSLCertificateFile /etc/pki/tls/certs/spacewalk.crt
SSLCertificateKeyFile /etc/pki/tls/private/spacewalk.key
RewriteEngine on
RewriteOptions inherit
SSLProxyEngine on
<IfModule mod_jk.c>
    JkMountCopy On
</IfModule>
...
</VirtualHost>
...

Restore some of the custom values you might have set previously in /etc/rhn/rhn.conf from the backup of your configuration files, such as:

  • debug = 3
  • pam_auth_service = rhn-satellite

Clean jabberd authentication database:

# rm -f /var/lib/jabberd/db/authreg.db

Regenerate kickstart files

# rm -f /var/lib/rhn/kickstarts/wizard/*

Restart Spacewalk

# /usr/sbin/rhn-satellite start

Update of monitoring setup

Recent Spacewalk installations may have set several important monitoring configuration values incorrectly. To correct these, run the following as root (note that you should run this command regardless of your current monitoring status; even on installations that never had monitoring enabled, running this script will have no ill effect):

# /usr/share/spacewalk/setup/upgrade/rhn-update-monitoring.pl

You may now choose to activate monitoring or both monitoring & monitoring scout on your Spacewalk.

If you had monitoring enabled previously and wish to re-enable it now (without having to do so in the web ui), run as root:

# /usr/share/spacewalk/setup/upgrade/rhn-enable-monitoring.pl

If you'd like to re-enable both monitoring and monitoring scout on your Spacewalk (without having to do so in the web ui), instead run as root

# /usr/share/spacewalk/setup/upgrade/rhn-enable-monitoring.pl --enable-scout

Restart Spacewalk

If all of the above steps completed successfully, you can start your upgraded Spacewalk server.

# /usr/sbin/rhn-satellite restart

Rebuild search indexes

After a successful upgrade, it is recommended to rebuild search indexes used by Spacewalk search engine (rhn-search service). This can be accomplished by the following:

# /etc/init.d/rhn-search cleanindex
