How to use the Typo Rails installer
Typo 4.4 includes an installer that makes it easy to install Typo.
Quick Start
Here's the short version:
$ gem install typo
$ typo install /var/www/my_typo_site
You'll need the following software installed on your system:
1. Ruby 1.8.6 or greater
2. RubyGems (
3. SWIG (
4. MySQL, PostgreSQL or SQLite 3
Most modern Unix systems should have all four of these easily available in
pre-built form.
Installing Typo
1. Install the Typo GEM.
Run 'gem install typo'. This will install the current version of Typo
along with all dependencies.
2. Create a working Typo installation in a directory somewhere.
Run 'typo install DIRECTORY'. Replace DIRECTORY with the name of the
directory that you want Typo to live in. This will copy all of Typo's
files into DIRECTORY, create a new database for Typo to use, and start
Typo running on a random port number.
3. Verify that Typo works for you. The installer will print a URL at the end
of the installation process; load it in a browser to test out Typo.
4. Once you're happy with Typo's configuration, follow the directions in
installer/apache.conf.example to run your Typo installation under Apache.
Upgrading Typo
The Typo installer can upgrade an existing installer-created Typo install by
simple running 'typo install DIRECTORY'. The installer will automatically
detect that it's upgrading an existing install and will attempt to preserve
the existing configuration as much as possible.
Starting and Stopping Typo
To stop Typo from running, run `typo stop /path/to/typo`. To restart it, run
`typo start /path/to/typo`. Since this Typo install uses Mongrel, not FastCGI,
you can't depend on your web server restarting it automatically on reboot.
You'll need to either create an init script or cron reboot entry to restart
it, depending on your host and/or privilege level.
Ask your hosting provider or the Typo mailing list (
if you need help with this.
Configuration Variables
Each Typo installation maintains a list of configuration variables. To see
the list for an existing install, run 'typo config DIRECTORY'. You can change
them via 'typo config DIRECTORY name1=value1 name2=value2...' For example:
typo config /var/www/typo web-server=mongrel_cluster
Here's a list of available configuration variables in Typo 4.0.0:
### bind-address
The `bind-address` controls which IP address(es) Mongrel uses. By default,
Mongrel listens for connections on all IP addresses that are in use on the
server. You can restrict this by setting `bind-address`. The most useful
setting is probably `bind-address=`, which will tell Mongrel to only
listen to connections from the local server.
### database
The `database` variable controls which Database driver Typo uses. By default,
this is `sqlite`. Setting it to any other value will supress SQLite-specific
upgrade and maintenance commands.
### port-number
The `port-number` variable controls which TCP port Mongrel uses. By default,
it's a random number between 4000 and 5000.
### rails-environment
This controls which Rails environment Typo uses. This defaults to
`production`; the other usable value is `development`.
### threads
The `threads` variable controls how many copies of Mongrel are used when using
the `mongrel_cluster` web server. Each thread listens on its own port number,
so setting `threads=2` while `port-number` is 4000 will make mongrel-cluster
run two copies of Mongrel, one listening on port 4000 and one on 4001.
### url-prefix
The `url-prefix` variable is used to tell Typo to run in a subdirectory
instead of the root of a specific URL hostname. For example, if you want Typo
to live at instead of,
then you'd need to set `url-prefix=/blog`.
### web-server
The `web-server` variable controls which server Typo uses. By default,
`web-server` is `mongrel`, but you can change it to `mongrel-cluster` or
`external`. If you use `external`, then 'typo PATH start` won't start a web
server of its own, and you'll have to provide your own web server. This is the
easiest way to use Typo with FastCGI--just set `web-server=external` and then
tweak `.htaccess`.
### Tests fail with ID=0
You didn't install Swig before installing `sqlite3-ruby`. Uninstall the SQLite
driver, install Swig, and then re-install `sqlite3-ruby`.
### SQLite dies with "unsupported file format"
You have multiple versions of SQLite3 installed, and you're using the command-line tool from one with the library from the other. Most likely this is on OS X with Darwinports. Make sure that `/opt/local/bin` is ahead of `/usr/bin` in your path.
### MySQL fails with timeout errors
Install the MySQL GEM. It's faster then Rails' default MySQL driver, and it
works substantially better.
### Typo crashes randomly
First, try running Typo under Webrick in the foreground to see if you can
reproduce the problem. Run `RAILS_ENV=production ./script/server webrick` from
your Typo directory and then see if you can get it to crash. If it dies, then
open a Trac ticket ( describing the problem and
include the crash message along with any relevant information from the logs.
Also include which version of Ruby (ruby -v), Rails, and Typo, and which OS
you're using.
Generally, if Typo suddenly exiting, it's probably caused by a bad Ruby
interpreter on your system.
