Programmatically construct your Apache configuration using a powerful DSL built in Ruby.
gem install apache-config-generator
Run apache-configurator <directory>
to create a new directory to hold your config files. A Rakefile and config.yml file will also be generated.
Configs center around the Apache::Config.build method:
Apache::Config.build('sites-available/my-site.conf') do server_name 'my-cool-website.cool.wow' document_root '/var/www/my-cool-website'
server_admin! “john@coswellproductions.com”
directory '/' do options :follow_sym_links, :indexes allow_from_all end location_match %r{^/secret} do deny_from_all basic_authentication "My secret", '/etc/apache2/users/global.users', :user => :john satisfy :any end rewrites "My old content" do cond "%{HTTP_REFERER}", '!^my-cool-website\.cool\.wow$' rule %r{\.(gif|jpg|png|pdf)$}, '/lol-image-stealer.html', :last => true, :redirect => true rewrite_test '/index.html', '/index.html', :http_referer => 'other.site' rewrite_test '/index.gif', '/lol-image-stealer.html', :http_referer => 'other.site' rewrite_test '/index.gif', '/index.gif', :http_referer => 'my-cool-website.cool.wow' end end
Notes on how the conversion works:
-
Methods within the build block are translated into NerdCapsed Apache directives.
-
Directives that house children take blocks that contain the child methods.
-
Directives that expect regular expressions take a Regexp object.
-
Passing a String as a parameter, by default, double-quotes it.
-
Passing in a Symbol does not quote the parameter.
** Some directives NerdCap Symbols, such as Options
-
Appending an exclamation point to the method turns off quoting.
-
Shortcut methods are defined as modules under the Apache module.
There are also sanity checks that occur when configuration is being generated:
-
Directives that rely on a path will check to see if the path exists.
-
Since you need to use Regexp objects for directives that require a regular expression, bad expressions will be flagged by the Ruby interpreter.
-
Rewrite rules can be tested with the rewrite_test method.
The above config is transformed into the following:
ServerName “my-cool-website.cool.wow” DocumentRoot “/var/www/my-cool-website” ServerAdmin john@coswellproductions.com
<Directory “/”> Options FollowSymLinks, Indexes Allow from all </Directory>
<LocationMatch “^/secret”> Deny from all
AuthType Basic AuthName “My secret” AuthUserFile “/etc/apache2/users/global.users” Require user john </LocationMatch>
RewriteCond “%{HTTP_REFERER}” “^!my-cool-website.cool.wow” RewriteRule “.(gif|jpg|png|pdf)$” “/lol-image-stealer.html” [L,R]
