The Zotonic shell command

The zotonic command runs a number of utility commands which all operate on a Zotonic instance.

The "zotonic" command lives in the bin/ folder of the Zotonic source. Putting this path into your PATH variable makes working with Zotonic a lot easier:

export PATH=$HOME/zotonic/bin:$PATH

The command determines where the Zotonic base dir is by looking at its path; it always assumes that its zotonic basedir is one dir up from where the binary itself is.

Currently, the following subcommands are implemented:

zotonic start

Start the background Zotonic server instance.

zotonic stop

Stop the background Zotonic server instance.

zotonic debug

Launch the Zotonic server interactively and get an EShell on the running instance.  There is a "start.sh" command in the root folder which is a shortcut for this command.

zotonic restart

Restart the background Zotonic server instance.

zotonic update

Update the server.  Compiles and loads any new code, flushes caches and rescans all modules.

zotonic addsite [options] <site_name>

Create a new site with [site_name] as its name.  This new site will be based on a so-called skeleton site. Currently there are two skeletons: 'blog' and 'empty'. "blog" is the default.

zotonic addsite -s empty yoursite

creates a new site called "yoursite" based on the skeleton called "empty". Full usage:

  -s <skel>    Skeleton site ('blog' or 'empty'; default: blog)

  -h <host>    Database host (default: 127.0.0.1)
  -p <port>    Database port (default: 5432)
  -u <user>    Database user (default: zotonic)
  -P <pass>    Database password (default: zotonic)
  -d <name>    Database name (default: zotonic)
  -n <schema>  Database schema (default: public)
  -a <pass>    Admin password (default: admin)

The "addsite" subcommand checks a file called $HOME/.zotonic-defaults for the default values to these options. This file is a file in bash-syntax which can define the following variables: SKEL, DBHOST, DBPORT, DBUSER, DBPASSWORD, DBDATABASE, DBSCHEMA, ADMINPASSWORD, DO_LINK.

zotonic installmodule <module_name>

Installs a module from the modules.zotonic.com repository into your Zotonic instance. The module will be checked out using source control (either git or hg) into the priv/modules folder:

zotonic installmodule mod_openid
Getting module index
** Installing mod_openid ...

** mod_openid OK

zotonic copysite [site_name] [source_server]

Copy [site_name] and its database content from the [source_server] over SSH and load its content into the filesystem and database of the local machine. You will need to have created the database zotonic_[site_name] for this to work.

Warning: This command will reset the content of the database to the content retrieved from the [source_server].  It does, however, generate and output a restore file in case this was run by accident and explains how to recover.

zotonic createdb [site_name]

Create a database called zotonic_[site_name] with the basic setup in place to host a Zotonic datastore. This script will likely need to be run as postgres unless zotonic has been granted CREATEDB in postgres as follows:

ALTER ROLE zotonic WITH CREATEDB

zotonic sitedir [site_name]

Get the absolute path for a site based on [site_name]

zotonic snapshot [site_name]

Take a version control snapshot of [site_name] including its database content.

This works differently from mod_backup in that it consistently uses the same filename for the SQL backup to make revision-based full site rollbacks possible.

zotonic update

Update the server.  Compiles and loads any new code, flushes caches and rescans all modules.

zotonic compilefile [files...]

Compiles a single file within the zotonic folder. This runs very fast and works very well on a save-hook of your text editor. In Emacs, it would be called like this:

(add-hook 'erlang-mode-hook
          '(lambda ()
             (add-hook 'after-save-hook '
                       (lambda ()
                         (call-process "/path/to/your/bin/zotonic" nil "*scratch*" nil "compilefile" buffer-file-name)
                         )
                       )
             ))
