AWStats with lighttpd on Ubuntu

Posted by Alpha Sun, 02 Dec 2007 22:23:00 GMT

Throughout this post, I’ll use foobar as a fake domain. You should replace this with the appropriate domain(s) for your own use.

First, install AWStats.

$ sudo apt-get install awstats

/etc/lighttpd.conf will need to be modified; this will be slightly different if you want to use a directory instead of a subdomain to check your stats.

/etc/lighttpd/lighttpd.conf

server.modules += ( "mod_cgi" )

$HTTP["host"] =~ "stats.foobar" {
  alias.url = ( "/icon/" => "/usr/share/awstats/icon/",
                "/css/" => "/usr/share/doc/awstats/examples/css/",
                "/cgi-bin/" => "/usr/lib/cgi-bin/" )
  cgi.assign = ( ".pl" => "/usr/bin/perl", ".cgi" => "/usr/bin/perl" )
}

Make sure this works by visiting http://stats.foobar/cgi-bin/awstats.pl. You should get an error message from the AWStats CGI file.

In /etc/awstats, make a awstats.foobar.conf file, replacing foobar with whatever is appropriate for your purposes.

/etc/awstats/awstats.foobar.conf

LogFile="/var/log/lighttpd/access.log"
LogType=W
LogFormat=1
SiteDomain="foobar"
HostAliases="localhost 127.0.0.1 REGEX[foobar$]"
DNSLookup=1
DirData="/var/lib/awstats"
DirCgi="/cgi-bin"
DirIcons="/icon"
SkipHosts="127.0.0.1 localhost REGEX[^192\.168\.]"

Run awstats.pl to initialize the statistics database.

$ sudo -u www-data /usr/lib/cgi-bin/awstats.pl -config=foobar -update

Your stats should now be visible at http://stats.foobar/cgi-bin/awstats.pl?config=foobar.

Now all that’s left is editing the crontab and logrotate configuration files to automatically populate the stats.

/etc/cron.d/awstats

0,10,20,30,40,50 * * * * www-data [ -x /usr/lib/cgi-bin/awstats.pl -a -f /etc/awstats/awstats.foobar.conf -a -r /var/log/lighttpd/access.log ] && /usr/lib/cgi-bin/awstats.pl -config=foobar -update >/dev/null

/etc/logrotate.d/lighttpd

prerotate
  /usr/lib/cgi-bin/awstats.pl -config=foobar -update
endscript

The code behind the Ultraviolet textfilter

Posted by Alpha Sun, 02 Dec 2007 02:55:00 GMT

To start, we need to install Ultraviolet. Since the library uses Oniguruma, we’ll have to install that as well.

$ sudo apt-get install libonig-dev
$ sudo gem install ultraviolet

Use irb to copy the CSS syntax files into Typo’s stylesheet directory. From the base directory of the Typo installation:

$ mkdir public/stylesheets/ultraviolet
$ irb -ruv
irb(main):001:0> Uv.copy_files 'xhtml', 'public/stylesheets/ultraviolet'

Copy one of the existing textfilters to use as a base.

$ cd vendor/plugins
$ cp -r typo_textfilter_code typo_textfilter_ultraviolet
$ cd typo_textfilter_ultraviolet
$ mv lib/typo_textfilter_code.rb lib/typo_textfilter_ultraviolet.rb

Modify init.rb to require the Ultraviolet textfilter instead of the code textfilter.

init.rb

# Include hook code here

require 'typo_textfilter_ultraviolet'

And last, edit lib/typo_textfilter_ultraviolet.rb to use Ultraviolet instead of the Syntax library.

lib/typo_textfilter_ultraviolet.rb

require 'uv'

class Typo
  class Textfilter
    class Ultraviolet < TextFilterPlugin::MacroPre
      plugin_display_name "Ultraviolet"
      plugin_description "Apply syntax highlighting to a code block using Ultraviolet"

      def self.help_text
        syntaxes, themes = [Uv.syntaxes, Uv.themes].map do |ary|
          ary.sort.map {|i| "* #{i.gsub('_', '\_')}" }.join("\n")
        end

        %{
This uses the [Ultraviolet](http://ultraviolet.rubyforge.org/) syntax highlighting engine. Options:

* **lang**. Sets the programming language. The default language is Ruby.
* **linenumber**. Turns on line numbering. Use `linenumber="true"` to enable.
* **theme**. Sets the theme. The default theme is Idle.

### Supported themes:
#{themes}

### Supported languages:
#{syntaxes}
}
      end

      def self.macrofilter(blog,content,attrib,params,text="")
        lang       = attrib['lang'] || 'ruby'
        theme      = attrib['theme'] || 'idle'
        linenumber = attrib['linenumber']

        text = text.to_s.gsub(/\r/,'').gsub(/\A\n/,'').chomp

        result = Uv.parse(text, 'xhtml', lang, linenumber, theme)

        set_whiteboard(blog, content, theme)

        "<notextile>#{result}</notextile>"
      end

      def self.set_whiteboard(blog, content, theme)
        content.whiteboard["page_header_ultraviolet_#{theme}"] = <<-HTML
          <link href="#{blog.base_url}/stylesheets/ultraviolet/#{theme}.css" media="all" rel="Stylesheet" type="text/css" />
        HTML
      end 
    end
  end
end
