Rudder

Hi Dennis,

Do you have any logs from your installation attempt?

Is it happening every time you try to install 2.7 agent with your kickstart?

And if you install yourself rudder agent using yum, is it happening too?

Hi Vincent,

The way of installing rudder-agent with my Kickstart post-install script hasn't changed since rudder-agent 2.5. With 2.7.6 it stopped working.

Actually my Kickstart post-install script invokes Yum:

#!/bin/bash
#
# Name:     rudder.sh
# Synopsis: Red Hat post-install script
# Author:   Dennis Cabooter <Dennis.Cabooter@snow.nl>
#

# Global vars
FILE_SERVER="10.0.0.2" 
POLICY_HUB="rudder.example.com" 

# Get required repos
wget --no-proxy \
  http://${FILE_SERVER}/kickstart/files/rhel/winz-rudder.repo \
  -O /etc/yum.repos.d/rudder.repo
wget --no-proxy \
  http://${FILE_SERVER}/kickstart/files/rhel/winz-rhel.repo \
  -O /etc/yum.repos.d/winz-rhel.repo

# Import GPG key
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

# Install & remove packages
yum -y install rsyslog rudder-agent

if rpm -q rsyslog > /dev/null 2>&1; then
  yum -y remove sysklogd
fi

# Configure Rudder Agent
tee /var/rudder/cfengine-community/policy_server.dat <<EOF
$POLICY_HUB
EOF

# Startup configs
chkconfig rsyslog on
chkconfig rudder-agent on

The local repo file looks as follows:

[winz-rudder]
name=Rudder 2.7 Repository
baseurl=http://yum.example.com/mirror/rudder-2.7/
gpgcheck=0

The captured output log is as follows:

I've tested some more bits and pieces:

• I disabled the post-install script and installed rudder-agent manually afterwards, which worked fine
• I did another kickstart without installing rudder-agent and checked for pcre, openssl and bzip2-libs and they were installed
• I re-enabled the kickstart post-install script, added a "rpm -qa | grep pcre", "rpm -qa | grep openssl" and "rpm -qa | grep bzip2-libs" to the post-install script and the packages turned out to be installed

The rudder-agent install needs libraries it somehow can't find during Kickstart post-install. When I once set up my Kickstart to install rudder-agent (back with 2.5 and 2.6) it did work. Now it doesn't.

For now I will add "yum -y install pcre bzip2-libs openssl" to keep the rudder-agent install happy.

A similar problem occurs when trying to install RHEL5 packageon RHEL6
lkco had the problem, which looks similar:

< lkco> ncharles: so, rudder agent on rhel6 start failed : /var/rudder/cfengine-community/bin/cf-serverd: error while loading shared libraries: libcrypto.so.6: cannot open shared object file
< lkco> ncharles: missing a dependency openssl098e on rudder-agent for rhel6
< lkco> arf i use bad repository
< lkco> i copy paste the /etc/yum.repos.d/rudder.repo file but i test the install on rhel6 (not rhel5)
< ncharles> ha, so you installed rhel5 package on rhel6
< lkco> yep :-/

The key lies in these lines:

[...]

This system has both 32 and 64 bits versions of the rudder-agent package installed. The package's dependencies only specify "pcre", not "pcre 32 bits" or "pcre 64 bits", so once one version is installed, yum doesn't worry about them anymore. The error you are seeing is most likely because you do have 64 bit versions of pcre, bzip2-libs and openssl, but the binary cf-agent remaining on your system is the 32 bit one.

A simple workaround would be to force yum to install the 64 bit package in your kickstart script: yum -y install rudder-agent.x86_64.

However, this indicates that there is something that could be done better in our packages, either:

• Force preference of the 64 bit package over 32, when possible
• Have each package depend on the ** bits versions of it's dependencies

This needs looking into.

I can confirm adding .x86_64 does solve the problem.
