Chef Server – Backup and Restore

* This assumes you’re using the regular debian/ubuntu install
and that you have a system with a fresh install of chef-server laying around

Backup your files on the OLD/Original Chef Server
This backs up all the chef configs/certs and couchdb configs and data

$ tar czvf chef-backup-`date +%Y-%m-%d-%s`.tar.gz /etc/couchdb /var/lib/chef /var/lib/couchdb /var/cache/chef /var/log/chef /var/log/couchdb /etc/chef

Transfer your files to the NEW Chef Server

$ scp old-chefserver:~/chef-backup*.tar.gz /tmp

Stop all chef services on the NEW Chef Server

$ for i in chef-server-webui chef-server rabbitmq-server jetty couchdb chef-solr ; do /etc/init.d/${i} stop ; done

Extract the backup file on to the NEW Chef Server

$ cd /tmp
$ tar xzvf chef-backup*.tar.gz

Delete the old rabbitmq data from your default installation on the NEW Chef Server

$ rm -fr /var/lib/rabbitmq/mneisa/*

Start rabbitmq in the foreground and recreate your user and tables on the NEW Chef Server

$ rabbitmq-server
$ rabbitmqctl add_vhost /chef
Creating vhost "/chef" ...
...done.
$ rabbitmqctl add_user chef testing
Creating user "chef" ...
...done.
$ rabbitmqctl set_permissions -p /chef chef ".*" ".*" ".*"
Setting permissions for user "chef" in vhost "/chef" ...
...done.
$ rabbitmqctl stop
Stopping and halting node rabbit@ubuntu02 ...
...done.

Start all the Chef Services on NEW Chef Server

$ for i in chef-solr couchdb jetty rabbitmq-server chef-server chef-server-webui ; do /etc/init.d/${i} start ; done

Verify your Chef Server is restored
http://NEW-CHEF-SERVER:4040
and verify the nodes and data or try the following knife commands

$ knife node list
$ knife node show mynode -a node
