Revision of Automatic install on Debian from Mon, 11/21/2011 - 21:02

These are the installation instructions that are recommended on Debian. Aegir dependencies (Apache, MySQL, PHP...) are also automatically installed. If you are managing the installation from a remote Windows computer, well-known open source tools for this task are for example PuTTY (a SSH client for command line), and WinSCP (a SFTP client with easy text file editing).

If you wish to install Debian packages over an existing manual install, it's possible. See the Debian upgrade procedures.

Debian packages are uploaded to http://debian.aegirproject.org/ shortly after a release. We eventually want to upload those packages to the official archives, but this will take some adaptation and time to sponsor the packages in.

1. Adding the project repositories

Use this command to add the Aegir package "Software Source" repository to your system:

To install other versions, see the developer instructions for the debian package.

2. Adding the archive key to your keyring

This repository self-signs packages uploaded to it (and packages uploaded are verified against a whitelist of trusted uploaders) using OpenPGP (GnuPG, to be more precise).

Use these commands to download and add the repository's PGP key, then update the package list on your system:

3. Adding backports for or manually installing Drush

If you are running Debian wheezy or later, or Ubuntu Natty 11.04 or later, you don't need to do anything here. The Drush package you need is available from your distribution's repositories.

If not, you should also configure backports repositories for Drush. Version 4.4 of Drush is now in Debian unstable, wheezy, squeeze-backports and Ubuntu Natty.

If you are running Debian Squeeze 6.0, add the following line to /etc/apt/sources.list :

You might also have to add a proper Pin-Priority before this works. Create a file called drush containing the following and drop it into /etc/apt/preferences.d:

Then run:

If you are running Debian lenny 5.0 or Ubuntu Maverick 10.10 or Karmic Koala or earlier, we recommend downloading and installing the Drush package manually. The version of Drush in the Ubuntu Universe repository for these versions of Ubuntu is outdated. If you are using Ubuntu Lucid LTS 10.04, you can install the Drush package manually or instead use Brian Mercer's PPA (Personal Package Archive) using the following command:

4. DNS configuration

Aegir requires a properly configured "FQDN" (Fully Qualified Domain Name) be assigned to the machine. In practice, this means that the hostname returned by the hostname -f and uname -n shell commands should resolve to the IP address for this server, and vice versa, with the resolveip command (included with the mysql-server package).

To set this up in a virtual machine (e.g. Virtualbox), here are the steps:

1. Create a new VM
2. Go to settings->network. Enable Adapter 2, and set to "host-only"
3. Install Ubuntu. Set hostname as FQDN during install
4. You may need to add the lines `auto eth1` and `iface eth1 inet dhcp` to /etc/network/interfaces

If you have a virtual machine already setup and want to change the FDQN:

1. change /etc/hostname using: `sudo hostname NEW_NAME`
2. change /etc/hosts using: `sudo nano /etc/hosts` and change name
3. reboot and test `hostname -f`, `uname -n`, `resolveip NEW_NAME`, `resolveip IP`
4. YMMV - Your Mileage May Vary :-)

5. Manual sudo configuration

If you are running Debian squeeze or later, or Ubuntu Lucid 11.04 or later, you don't need to do anything here. The Aegir package configures sudoers automatically.

If not, you will need to manually modify your /etc/sudoers file to add the following line:

The line above assumes that you have created a user aegir as specified in the installation instructions.

6. Installing Aegir

To install aegir, frontend and backend, use the following command:

If apt-get reports that the aegir packages have unmet dependencies, then make sure that you have installed Drush (as explained above). On a debian system, you can force the install of Drush from the squeeze-backports repository:

Then install aegir using the apt-get command above.

This will prompt you for the required information (MySQL password, Postfix configuration...) and go ahead with the install.

During the Postfix configuration, the following options appear: "No configuration, Internet site, Internet with smarthost, Satellite system, Local only". That first text screen only allows to use the tab key to select "OK", and then the enter key to display a second screen where you can select one of the choices. The default is "Internet site", useful in most cases to enable the server to send email messages, for example to the admin.

At the end of the installation, you will receive an email message or, if the user "aegir" has been assigned with a local email account during the installation, the file /var/mail/aegir will contain the message. It will include a one-time login to your new Aegir control panel, that is a URL to copy into your browser so that you can set the password for the "admin" user.

7. Custom distributions

If you have your own makefile, you can go ahead with the above process, but change the makefile to the one you want:

echo debconf aegir/makefile string /var/aegir/makefiles/aegir/aegir-koumbit.make | debconf-set-selections
apt-get install aegir

This allows you to specify the makefile path for your custom distribution of Aegir. To maintain these customizations, you'll need to ensure you do the same when upgrading.

An example aegir-koumbit.make file could look like:

Note that for this to work, you may need the patch from this issue, allowing drush_make to reference absolute system paths.

8. Troubleshooting the install

To make the install smoother, the install command is run without much debugging information, which can make diagnostics pretty hard. For this, there's a special environment variable you can set that will trigger debugging output. Install aegir with this:

You can build your own Debian packages from our repositories using those instructions.

Note: the DEBUG flag is deprecated. In 1.x releases, it is accepted, but in 2.x it won't. You should use DPKG_DEBUG instead, it is usable starting from 1.1-4.
