NOTE: Nigthly repo contains developers snapshot and is not suitable in production environment.
Additional repos & packages
RHEL, CentOS 6 and Fedora 14 & 15
For Spacewalk on RHEL 6 and Fedora, a couple of additional dependencies are needed from jpackage. If repo is broken, mirror list here: http://www.jpackage.org/mirroring.php Please configure the following yum repository before beginning your Spacewalk installation:
cat > /etc/yum.repos.d/jpackage-generic.repo << EOF [jpackage-generic] name=JPackage generic #baseurl=http://mirrors.dotsrc.org/pub/jpackage/5.0/generic/free/ mirrorlist=http://www.jpackage.org/mirrorlist.php?dist=generic&type=free&release=5.0 enabled=1 gpgcheck=1 gpgkey=http://www.jpackage.org/jpackage.asc EOF
We specifically want 5.0 generic directory in the above URL. Make sure, you do not use the jpackage-generic repository on RHEL 5.
CentOS - CR repository
selinux update need CR repository:
cat > /etc/yum.repos.d/cr.repo << EOF [CR-repository] name=CR Repository #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cr baseurl=http://mirror.centos.org/centos/$releasever/cr/$basearch/ enabled=1 gpgcheck=1 EOF
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:
EPEL 5 (use for RHEL 5)
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
EPEL 6 (use for RHEL 6)
rpm -Uvh http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.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."
When using RHEL 6, make sure you are subscribed to following channels as well:
- Red Hat High Availability Server 6
- Red Hat Optional Server 6
Follow the instructions to use EPEL 5 with the additions:
- Necessary packages rhn-client-tools and rhnlib were removed from CentOS, they can be found in spacewalk-client repo. Setup it by installing spacewalk-client-repo package.
rpm -ihv http://spacewalk.redhat.com/yum/1.5-client/RHEL/5/x86_64/spacewalk-client-repo-1.5-1.el5.noarch.rpm
- Import Redhat's RPM GPG key:
# wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release http://www.redhat.com/security/37017186.txt # rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
In order to get Spacewalk to run with Oracle database backend, you need:
- the Oracle Instant Client
- an oracle database, this can either be:
In order to get Spacewalk ro run with PostgreSQL database backend, you need PostgreSQL 8.4 server installed on the same or different machine. Use PostgreSQLServerSetup as a guide to get the server installed and setup.
Please note that the functionality of Spacewalk on PostgreSQL is limited and sooner than later you may hit Internal Server Error.
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 [main] .... exclude=cobbler-web
There is a workaround to be able to install cobbler-web and use it alongside Spacewalk. Instructions can be found at CobblerWebWorkaround.
Just ask yum to install the necessary packages. This will pull down and install the set of RPMs required to get Spacewalk to run.
If you tend to use the Oracle backend:
yum install spacewalk-oracle
If you prefer the PostgreSQL backend:
yum install spacewalk-postgresql
You may want to take a look at the PostgreSQL page for further information about the PostgreSQL backend.
Configuring the firewall
Spacewalk needs various inbound ports to be connectible. Assuming you have a default RHEL/CentOS set up, proceed as following:
For RHEL 5/CentOS 5/Scientific Linux 5
iptables -D RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited iptables -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 443 -j ACCEPT iptables -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 80 -j ACCEPT iptables -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited service iptables save service iptables restart
For RHEL 6/Scientific Linux 6
iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited iptables -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT iptables -A INPUT -j REJECT --reject-with icmp-host-prohibited service iptables save service iptables restart
Add port 5222 if you want to push actions to client machines and 5269 for push actions to a Spacewalk Proxy, 69 udp if you want to use tftp.
Your Spacewalk server should have a resolvable FQDN such as 'hostname.domain.com'. If the installer complains that the hostname is not the FQDN, do not use the --skip-fqdn-test flag to skip !
The setup requires that the database account has a password.
Note: Please don't use '#' (number sign/pound/hash) and '@' in your database password otherwise installation will fail.
Once the Spacewalk RPM is installed you need to configure the application, you can run:
An example session is as follows:
# spacewalk-setup --disconnected * Setting up Oracle environment. * Setting up database. ** Database: Setting up database connection for Oracle backend. Database service name (SID)? XE Username? spacewalk Password? ** Database: Testing database connection. ** Database: Populating database. *** Progress: #### * Setting up users and groups. ** GPG: Initializing GPG and importing key. ** GPG: Creating /root/.gnupg directory You must enter an email address.

Configuring Spacewalk with an Answer File
You can also configure Spacewalk by using an answer file, by running spacewalk-setup like
spacewalk-setup --disconnected --answer-file=<FILENAME>
An example answer file for the Oracle database backend:
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 db-backend=oracle db-user=spacewalk db-password=spacewalk db-name=xe db-host=localhost db-port=1521 enable-tftp=Y
If you do not supply a value or leave out a key you will be prompted to supply that answer.
For PostgreSQL, you need to create something like this:
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 db-backend=postgresql db-name=spaceschema db-user=spaceuser db-password=spacepw db-host=host db-port=5432 enable-tftp=Y
After spacewalk-setup is complete your application is ready to go!
Once you've made sure you can login to the Spacewalk WebUI, you can then proceed to the next step: Uploading Content.
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
