Zotonic runs on Linux, Mac OS X and (not officially) on Windows.
Before running Zotonic, you must make sure your system meets the minimum requirements to do so. Zotonic needs the following software installed:
If you meet these requirements, head straight on to Installing Zotonic, otherwise, read on below for the specifics on these.
You can check if you have Erlang installed by typing the following command in a terminal:
The output should be something like:
Erlang R16B03 (erts-5.9.2) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false] Eshell V5.9.2 (abort with ^G) 1>
(Press ctrl+c twice to exit)
If your version is below release R15B03, you need to upgrade. If you don’t have Erlang installed, we recommend downloading a build for your operating system from the Erlang Solutions website:
You can check if you have ImageMagick installed by typing the following command in a terminal:
$ convert -version
This tells you which version of ImageMagick is installed:
Version: ImageMagick 6.7.7-10 2012-08-17 Q16 http://www.imagemagick.org
You can check if you have PostgreSQL installed by typing the following command in a terminal:
$ psql -V
Returns the PostgreSQL version:
psql (PostgreSQL) 9.1.6
To let Postgres users access the database from Zotonic, you need to make a configuration change in Postgres’ configuration file pg_hba.conf.
On Linux, this file is located in /etc/postgresql/<pg version>/main/pg_hba.conf. Add the following lines:
# Zotonic settings local all zotonic ident host all zotonic 127.0.0.1/32 md5 host all zotonic ::1/128 md5
These settings assume that your Zotonic sites are going to connect with a Postgres user called zotonic. For other user names, adjust accordingly. Do not forget to restart Postgres after you’ve made this change.
We recommend you install Erlang from the Erlang solutions website:
The other requirements are easily fetched with apt:
sudo apt-get install build-essential postgresql imagemagick git
If you’re running on FreeBSD, make sure you’ve got the ‘GNU’ ‘make’ (check with make --version, which should give you GNU, and version info). If you don’t have GNU make, Zotonic will give an error when trying to compile.
With Homebrew you can install Erlang and ImageMagick using the following commands:
brew install erlang brew install imagemagick
Alternatively, with MacPorts:
sudo port install erlang +ssl sudo port install ImageMagick
For PostgreSQL choose either:
Currently, Zotonic is not officially supported on the Windows platform. However, the main dependencies Erlang, PostgreSQL and ImageMagick do work on Windows, so, if you’re adventurous, it should be possible to get it running.
We have included user-contributed start.cmd and build.cmd batch-scripts which used to work on Windows, but have not been kept up-to-date with recent changes. Expect some major tweaking to get this back on track.
