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 Installation, 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 R15B02 (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 R14B03, you need to upgrade.
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.
You can install Erlang from the default Ubuntu repositories:
sudo apt-get install build-essential postgresql imagemagick erlang-base erlang-tools \ erlang-parsetools erlang-inets erlang-ssl erlang-eunit erlang-dev erlang-xmerl erlang-src
A recent Erlang should be installed from a custom PPA by running:
sudo add-apt-repository ppa:scattino/ppa sudo apt-get update sudo apt-get install build-essential erlang-base erlang-ssl postgresql imagemagick
You’ll need to build erlang from source. Before building, make sure you install these packages:
sudo apt-get install build-essential libncurses5-dev m4 sudo apt-get install openssl libssl-dev sudo apt-get install unixodbc-dev
Alternatively, you can install a precompiled recent Erlang from the following PPA: https://launchpad.net/~scattino/+archive/ppa
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’re not running GNU-make as a default, edit the Makefile to run with ‘gmake’ (make sure gmake is available first).
With MacPorts you can install Erlang and ImageMagick using the following commands:
sudo port install erlang +ssl sudo port install ImageMagick
EnterpriseDB has an excellent PostgreSQL installer available at http://www.enterprisedb.com/products/pgdownload.do#osx
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 are supposed to work on Windows.
