In this document, $HOST is equivalent to $(hostname) (i.e. the first part of the fqdn).

1. Deploying an Update

Push all changes to the release branch, and tag as release_${isodate} (e.g. release_20121022 for October 22nd, 2012). If you make multiple releases in a day append -N starting with 1.

Running the deploy-domtool script will then pull, build, and install domtool sitewide.

To deploy on an individual host, use the deploy-domtool-on-host script.

2. New Machine

Ensure these Debian packages are installed: mlton libssl-dev libpcre3-dev rsync (our AutomatedSystemInstall does this for you)

Create /afs/hcoop.net/common/domtool/build/$HOST

Clone the domtool2 repository and checkout release:

cd /afs/hcoop.net/common/domtool/build/$HOST
git clone /afs/hcoop.net/user/h/hc/hcoop/.hcoop-git/domtool2.git domtool2
cd domtool2
git checkout release

If a slave (the usual setup):

• Add node to HOSTS_SLAVE (unless it is the new master) variable deploy-domtool script. Afterward the general deployment procedure should work.

• Create the needed SSL certificate for the node by running (on the machine with the domtool certificate authority): domtool-addcert $HOST

You will also need to create various work directories, although the preseed for the particular install should handle that.

The first time DomTool is deployed to a host, it should be done manually using deploy-domtool-on-host --slave --bootstrap to install the proper sysvinit files.

2.1. Work Directories

DomTool should create these during installation, but it does not yet (see Bug 935).

Domtool's scratch directory:

sudo mkdir /var/domtool
sudo chown domtool.nogroup /var/domtool

Create subdirectories of /var/domtool in the same way, depending on which services this slave will be managing: (incomplete)

• bind: /var/domtool/zones

• apache: /var/domtool/vhosts and /var/domtool/apache2_logs

• firewall: /var/domtool/firewall

Domtool's log file:

sudo touch /var/log/domtool.log
sudo chown domtool.nogroup /var/log/domtool.log

3. etc.

• To make everyone's Emacs autoload domtool-mode by default, put this in /usr/local/share/emacs/site-lisp/default.el:

(add-to-list 'load-path "/usr/local/share/emacs/site-lisp/domtool-mode")
(require 'domtool-mode-startup)

• If this slave manages BIND, make sure a UNIX group bind_config exists, as Domtool will try to chgrp all relevant configuration to that group. It doesn't really matter which users belong to the group, as these actions are performed as root. If the group doesn't exist, you can create it with:

sudo groupadd bind_config

• If this slave manages BIND, make sure that the directory /etc/bind/zones exists.

• Configure Certifications and keys

  • If setting up the disptacher possibly set up local CA and SSL, and certificate for a node as said on DomTool/SslProcedures, and manually copy the certificate and key into the right places:

    mkdir ~domtool/keys/$HOST
    cp serverkey.pem ~domtool/keys/$HOST/key.pem
    cp servercert.pem ~domtool/certs/$HOST.pem

• Be sure a keytab for domtool is in /etc/keytabs/domtool, with permissions set so that domtool can read it but random users can't. You might copy the file from deleuze.

• Try starting the slave server:

sudo /etc/init.d/domtool-slave start

• After ensuring that the slave starts, make the slave (or server) start at boot

sudo insserv domtool-slave
