Bug #263

Updated by Daniel Curtis over 10 years ago

I decided to separate the administrative server to a virtual node. To do this I installed @puppetmaster@ and @puppetmaster-passenger@: 
 <pre> 
 apt-get install puppetmaster puppetmaster-passenger 
 </pre> 

 I then used rsync to synchronize the configuration files and cache from the old server to the new server: 
 <pre> 
 rsync -avh -e ssh root@puppetmaster.orig.net:/etc/puppet /etc/ 
 rsync -avh -e ssh root@puppetmaster.new.net:/var/lib/puppet /var/lib/ 
 </pre> 
 This includes CA and SSL certificates, and configuration reports. This should allow a transparent migration to the new puppet master server by preserving the contents of the old puppet master server. 

 I dumped the puppet SQL database: 
 <pre> 
 mysqldump -u root -p puppet > /path/to/backup/puppet.sql 
 </pre> 

 Then restored it into the new server: 
 <pre> 
 mysql -u root -p 

 CREATE DATABASE puppet; 
 GRANT ALL PRIVILEGES TO 'puppetuser'@'localhost' IDENTIFIED BY 'SuperSecretPassword'; 
 FLUSH PRIVILEGES; exit 
 EXIT 

 mysql -u root -p puppet < /path/to/restore/puppet 
 </pre> 

 I then set the puppet clients to use the new puppet master. 
 However I got an error: 
 > err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not autoload active_record: uninitialized constant ActiveRecord 

 
 > err: Could not retrieve catalog from remote server: Error 400 on SERVER: cannot load such file -- mysql 

 
 To solve this I had to install a few ruby gems: the active record gem: 
 <pre> 
 gem install metaclass mocha passenger railties rspec rspec-core rspec-expectations rspec-mocks ruby-mysql sprockets sprockets-rails stomp systemu test-unit thor tilt will_paginate actionmailer activerecord 
 gem install mysql daemon_controller ftools hiera hiera-puppet hike hoe httpclient 
 </pre> 

 I started getting another error on the puppet clients: 
 > err: Could not retrieve catalog from remote server: Error 400 on SERVER: Puppet::Parser::Compiler failed with error ArgumentError: wrong number of arguments (1 for 0) on node web4.altservice.com
