• Python 2.x >= 2.6
• PyYAML

If you use WebSocket protocol hybi-10, required misultin 0.9-dev higher.

Install and boot for Fedora 14:

$ sudo yum install -y PyYAML erlang-erlsyslog erlang-misultin erlang-mochiweb erlang-sasl
$ sudo rpm -ivh http://shirasu.googlecode.com/files/shirasu-0.2-1.fc14.i386.rpm

• Stats
• Commandline Monitor
• Network Monitor

If you use Network Monitor, require some Python libraries :

$ mkvirtualenv pingman
$ workon pingman
$ pip install -r rel/files/sample/scripts/pingman.packages.txt

You can configure the Shirasu.ws by editing YAML file. ex) `/etc/shirasu/shirasu.yaml`:

shirasu:
  - port: 8000

shirasu_stat:
  /stat: true

shirasu_http_serve:
  /: /var/lib/shirasu/sample/www

shirasu_http_stream:
  /stream.twitter.com/1/statuses/sample.json: "http://<SCREEN_NAME>:<PASSWORD>@stream.twitter.com/1/statuses/sample.json"
  /exchange/USDJPY:
  - "http://chartapi.finance.yahoo.com/instrument/1.0/USDJPY=X/chartdata;type=quote;range=2d/csv/"

shirasu_commandline:
  /commandline/traceroute: "traceroute google.com"
  /commandline/ping:
  - "ping -c  5 localhost"
  - "ping -c 10 localhost"

Boot from source of develop version:

$ git clone git://github.com/MiCHiLU/shirasu.git
$ cd shirasu
$ git checkout dev
$ make debug

• draft-ietf-hybi-thewebsocketprotocol-10
• path based channel

• provide RPM package for Fedora 14
• YAML config
• serve static files via HTTP
• syslog support

• response body of HTTP GET request over WebSocket

• sample code

shirasu is used misultin that is an Erlang library for building fast lightweight HTTP servers. (see https://github.com/ostinelli/misultin)

enable to provides UDP syslog reception. edit `/etc/rsyslog.conf`:

$ModLoad imudp.so
$UDPServerRun 514

add rules to `/etc/rsyslog.conf`:

user.*    /var/log/shirasu/shirasu.log

and restart rsyslog:

$ sudo service rsyslog restart

checkout from Shiwasu.ws repository, and build RPM package:

$ cd shirasu
$ git checkout shirasu-0.2
$ make dist
$ RELEASE=1 make package
