  • If you use LDAP as a central identity service and wish to pull user and group information from it, see SpacewalkWithLDAP

Setting up Spacewalk repo

RPM downloads of the project are available through a yum repository

To use this repository install spacewalk-repo with commands below:

Red Hat Enterprise Linux, CentOS

rpm -Uvh

Fedora 11

rpm -Uvh

Fedora 12

rpm -Uvh

Nightly builds

If you want to use the nightly builds, add a .repo file pointing to the nightly repository:

cat > /etc/yum.repos.d/spacewalk.repo << 'EOF'
# RHEL 5 / CentOS 5
# Fedora 12
# Fedora 13

NOTE: Nigthly repo contains developers snapshot and is not suitable in production environment.

Additional repos & packages


For Spacewalk on Fedora, a couple of additional dependencies are needed from jpackage. Please create the following yum repository before beginning your Spacewalk installation:

cat > /etc/yum.repos.d/jpackage.repo << EOF

Note: the dirs for f11 and f12 do not contain the rpms yet

Red Hat Enterprise Linux 5

Spacewalk requires a Java Virtual Machine with version 1.6.0 or greater. EPEL - Extra Packages for Enterprise Linux contains a version of the openjdk that works with Spacewalk. Other dependencies can get installed from EPEL as well. To get packages from EPEL just install this RPM:

BASEARCH=$(uname -i)
rpm -Uvh$BASEARCH/epel-release-5-3.noarch.rpm

Please make sure you have only one java version installed. Otherwise you get error messeges like :

  • " bad major version at off set=6" or
  • "INFO: validateJarFile(/usr/share/tomcat5/webapps/rhn/WEB-INF/lib/jspapi.jar) - jar not loaded."

CentOS 5

Follow the instructions for Red Hat Enterprise Linux 5 with the additions:

Oracle Pre-Requisites

In order to get Spacewalk to run you need the Oracle client and an Oracle 10g database server. The easiest way to do this is to install Oracle XE and the Oracle Instant Client. Instructions on how to do this can be found on the Oracle 10g Express Edition Setup page.

Conflicting Packages

There is an open bug 593402 that identifies the package cobbler-web as conflicting with Spacewalk's Taskomatic process. Until the issue is addressed, it is recommended that the cobbler-web package be removed from the Spacewalk server.

yum remove cobbler-web

Yum can also be configured to exclude that package in the future by adding the following entry to the main section in /etc/yum.conf:

vi /etc/yum.conf


Installing Spacewalk

Just ask yum to install the necessary packages. This will pull down and install the set of RPMs required to get Spacewalk to run.

1.0 installation:

If you tend to use the Oracle backend:

yum install spacewalk-oracle 

If you prefer the PostgreSQL backend:

yum install spacewalk-postgresql 

Note: PostgreSQL support is in early development stage. You may want to take a look at the PostgreSQL page for further information.

Configuring Spacewalk

Note: Your Spacewalk server should have a resolvable FQDN such as ''. If the installer complains that the hostname is not the FQDN, do not use the --skip-fqdn-test flag to skip !

Also, this will not work unless the spacewalk account in the database has a password. You can set up a password by logging in to sqlplus with the sys account and using the command

PASSWORD user_name

where user_name = spacewalk. Don't use '#' (number sign/pound/hash) in your database password otherwise installation will fail.

Once the Spacewalk RPM is installed you need to configure the application, you can run:

spacewalk-setup --disconnected

An example session is as follows:

[root@fjs-0-02 yum.repos.d]# spacewalk-setup --disconnected

Configuring Spacewalk with an Answer File

You can also configure spacewalk by using an answer file. To configure spacewalk by using an answer you just need to run the following

spacwalk-setup --disconnected --answer-file=<FILENAME>

An example answer file is as follows

admin-email = root@localhost
ssl-set-org = Spacewalk Org
ssl-set-org-unit = spacewalk
ssl-set-city = My City
ssl-set-state = My State
ssl-set-country = US
ssl-password = spacewalk
ssl-set-email = root@localhost
ssl-config-sslvhost = Y

NOTE: If you do not supply a value or leave out a key you will be prompted to supply that answer

After spacewalk-setup is complete your application is ready to go! Be sure to use the FQDN of the host when you connect.

NOTE: If you notice you missing some buttons and channels that have been created aren't visible in you UI edit /etc/sysconfig/httpd and change:

export ORACLE_HOME=/opt/oracle
export NLS_LANG=english.AL32UTF8


export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server

Once you've made sure you can login to the Spacewalk web UI, you can then proceed to the next step: Uploading Content.

Managing Spacewalk

Spacewalk consists of several services. Each of them has its own init.d script to stop/start/restart. If you want manage all spacewalk services at once use

/usr/sbin/rhn-satellite [stop|start|restart].
