multiple puppet masters

[vioilly]

Hi,

I would like to set up an additional puppet master but have the CA server handled by only 1 puppet master. I have set this up as per the documentation here:

http://docs.puppetlabs.com/guides/scaling_multiple_masters.html

I have configured my second puppet master as follows:

[main]
...
ca = false
ca_server = puppet-master1.test.net

I am using passenger so I am a bit confused how the virtual-host.conf file should look for my second puppet-master2.test.net. Here is mine:

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18
PassengerRuby /usr/bin/ruby

<Proxy balancer://puppet_ca>
  BalancerMember http://puppet-master1.test.net:8140
</Proxy>

ProxyPassMatch ^(/.*?)/(certificate.*?)/(.*)$ balancer://puppet_ca/
ProxyPassReverse ^(/.*?)/(certificate.*?)/(.*)$ balancer://puppet_ca/

Listen 8140

<VirtualHost *:8140>
    SSLEngine on
    SSLProtocol -ALL +SSLv3 +TLSv1
    SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

    SSLCertificateFile      /var/lib/puppet/ssl/certs/puppet-master2.test.net.pem
    SSLCertificateKeyFile   /var/lib/puppet/ssl/private_keys/puppet-master4.test.net.pem
    #SSLCertificateChainFile /var/lib/puppet/ssl/ca/ca_crt.pem
    #SSLCACertificateFile    /var/lib/puppet/ssl/ca/ca_crt.pem
    # If Apache complains about invalid signatures on the CRL, you can try disabling
    # CRL checking by commenting the next line, but this is not recommended.
    #SSLCARevocationFile     /var/lib/puppet/ssl/ca/ca_crl.pem
    SSLVerifyClient optional
    SSLVerifyDepth  1
    # The `ExportCertData` option is needed for agent certificate expiration warnings
    SSLOptions +StdEnvVars +ExportCertData

    # This header needs to be set if using a loadbalancer or proxy
    RequestHeader unset X-Forwarded-For

    RequestHeader set X-SSL-Subject %{SSL_CLIENT_S_DN}e
    RequestHeader set X-Client-DN %{SSL_CLIENT_S_DN}e
    RequestHeader set X-Client-Verify %{SSL_CLIENT_VERIFY}e

    DocumentRoot /etc/puppet/rack/public/
    RackBaseURI /
    <Directory /etc/puppet/rack/>
            Options None
            AllowOverride None
            Order allow,deny
            allow from all
    </Directory>
</VirtualHost>

 

I have commented out the #SSLCertificateChainFile, #SSLCACertificateFile & #SSLCARevocationFile - this is not a CA server so not sure I need this. How would I get passenger to work with these?

I would like to use ProxyPassMatch which I have configured as per the documentation. I don't want to specify a ca server in every puppet.conf file.

I am getting this error when trying to get create a cert from a puppet client pointing to the second puppet master server (puppet-master2.test.net):

[root@puppet-client2 ~]# puppet agent --test
Error: Could not request certificate: Could not intern from s: nested asn1 error
Exiting; failed to retrieve certificate and waitforcert is disabled

On the puppet client I have this

[main]

server = puppet-master2.test.net

What have I missed?

Cheers, Oli

I was wondering if on the 2nd puppet master I have installed, whether or not I need the SSLEngine on for my virtual host configuration file? I have tried this, but with no luck...

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.18
PassengerRuby /usr/bin/ruby

# you probably want to tune these settings
PassengerHighPerformance on
PassengerMaxPoolSize 12
PassengerPoolIdleTime 1500
# PassengerMaxRequests 1000
PassengerStatThrottleRate 120
RackAutoDetect Off
RailsAutoDetect Off

Listen 8140

<VirtualHost *:8140>
    SSLEngine off

    ProxyPassMatch ^/([^/]+/certificate.*)$ https://puppet-master1.test.net:8140/$1

    # Obtain Authentication Information from Client Request Headers
    SetEnvIf X-Client-Verify "(.*)" SSL_CLIENT_VERIFY=$1
    SetEnvIf X-SSL-Client-DN "(.*)" SSL_CLIENT_S_DN=$1

    DocumentRoot /etc/puppet/rack/public/
    RackBaseURI /
    <Directory /etc/puppet/rack/>
            Options None
            AllowOverride None
            Order allow,deny
            allow from all
    </Directory>
</VirtualHost>

Anyone any ideas on this?

Cheers,
Oli
