Comment: $HOST is short hostname

=== Work Directories ===

DomTool should create these during installation, but it does not yet (see [[https://bugzilla.hcoop.net/show_bug.cgi?id=935|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`

 * Create subdirectories of `/var/domtool` in the same way, depending on which services this slave will be managing. If this slave manages BIND, create `/var/domtool/zones`. If this slave manages Apache, create `/var/domtool/vhosts` and `/var/domtool/apache2_logs`.
 * 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
}}}
Line 55: Line 63:
 * Create Domtool's log file and set the right permissions on it:
{{{
sudo touch /var/log/domtool.log
sudo chown domtool.domtool /var/log/domtool.log
}}}
Line 67: Line 71:
 * 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.  * Be sure a keytab for `domtool` is in `/etc/keytabs/domtool`, with permissions set so that only `domtool` can read it.

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)

$HOST = $(hostname --short) (e.g. fritz.hcoop.net is fritz, we should probably switch to using the FQDN).

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 -b release /afs/hcoop.net/user/h/hc/hcoop/.hcoop-git/domtool2.git domtool2

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

Work directories under /var/domtool may need to be created, but at hcoop puppet should automatically create them.

The first time DomTool is deployed to a host, it should be done manually using deploy-domtool-on-host --slave --bootstrap to ensure systemd units are installed and enabled.

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

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 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 only domtool can read it. This is handled by puppet automatically at hcoop.

  • Try starting the slave server: 

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

sudo insserv domtool-slave
