Zotonic has the capability of serving more than one site at a time. You can have multiple sites enabled, each with its own set of templates, database and dispatch rules. Each site has its own hostname.
Create a site¶
First, prepare the database. In your terminal, connect to PostgreSQL:
$ sudo -u postgres psql (enter your OS password)
And create a database user for Zotonic. You may want to change the password:
postgres=# CREATE USER zotonic WITH PASSWORD 'zotonic';
Now, either give this user create rights to have Zotonic automatically create the database for you (recommended):
postgres=# ALTER USER zotonic CREATEDB;
Or create the site database manually:
postgres=# CREATE DATABASE zotonic WITH OWNER = zotonic ENCODING = 'UTF8'; postgres=# GRANT ALL ON DATABASE zotonic TO zotonic; postgres=# \c zotonic postgres=# CREATE LANGUAGE "plpgsql";
And quit postgres:postgres=# q
Now that there is a database Zotonic can be started. We do this in debug mode so that all console output is visible:
$ bin/zotonic debug
In a new terminal window, Edit your
/etc/hostsfile, adding an entry for
yoursite.test(the site hostname) to point at your local host:
Create a new Zotonic site, based on the ‘blog’ skeleton site:
$ bin/zotonic addsite -s blog yoursite
Zotonic has to be running for the
addsitecommand to succeed.
Finally, point your browser to http://yoursite:8000 to see your new site. You can log into the admin at http://yoursite:8000/admin with the password that you can find in your site’s configuration file:
yoursite/priv/zotonic_site.configin the zotonic user directory.
If anything goes wrong, see the Installation.
You can stop Zotonic by typing twice Ctrl-C at the Erlang command prompt.
If you want to start Zotonic in the background then use:
$ bin/zotonic start
This can be stopped with:
$ bin/zotonic stop
Anatomy of a site¶
A Zotonic site is a folder which lives in the zotonic user directory and contains at least:
priv/zotonic_site.configfile: sets the site’s hostname and other parameters
src/sitename.erlfile: initialises the site.
src/sitename.app.srcfile: an OTP app source file
In fact, a site is a special type of module. Like modules, sites usually contain additional resources such as templates, dispatch rules and data . Unlike modules, however, sites have their own hostname and database connection.
