I need to write some scripts to make changes to Apache conf files, namely to add/update VirtualHosts. I plan on doing this in Ruby. before I write my own, are there any scripts/rubygems which allow Ruby to parse/modify Apache conf files, specifically <VirtualHost>
directives?

Not sure if StackOverflow would be a better place. Let's try ServerFault first and see what happens :-) – Josh Mar 12 '10 at 19:50

I ended up just writing my own ruby script... Not very well done, but in case anyone needs it, here's the guts of it. It is looking for the contents of the <VirtualHost></VirtualHost>
tag so that it can create a second <VirtualHost>
with a ServerName
which is a subdomain of our wildcard SSL cert...
begin
logMsg "Updating apache config file for user #{user} (#{domain_httpd_conf})"
domain_httpd_conf_io = File.open(domain_httpd_conf,File::RDONLY)
ip_addr = ''
main_vhost_config = []
ssl_vhost_config = [" ServerName #{auto_ssl_domain}",' Include "conf/wildcard-ssl.conf"']
indent = 1
while line = domain_httpd_conf_io.gets
line_indented = ' '*indent+line.strip
if line =~ /^[[:space:]]*<VirtualHost ([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)(:[0-9]+)[^>]*>/
ip = $1
elsif line =~ /^[[:space:]]*<\/VirtualHost>/
break 2
elsif line =~ /^[[:space:]]*(ServerAlias|ServerName).*/
main_vhost_config.push line_indented
else
if line =~ /^[[:space:]]*<[^\/]/
indent += 1
elsif line =~ /^[[:space:]]*<[\/]/
indent = [1, indent-1].max
line_indented = ' '*indent + line.strip
end
main_vhost_config.push line_indented
ssl_vhost_config.push line_indented
end
end
main_vhost_config.push " Include #{extraconf_dir}/*.conf"
domain_httpd_conf_io.close
domain_httpd_conf_io = File.open(domain_httpd_conf,File::WRONLY||File::TRUNC)
domain_httpd_conf_io.puts "<VirtualHost #{ip}:80 #{ip}:8080>"
domain_httpd_conf_io.puts main_vhost_config
domain_httpd_conf_io.puts "</VirtualHost>"
domain_httpd_conf_io.puts
domain_httpd_conf_io.puts "<VirtualHost #{ip}:443 #{ip}:8888>"
domain_httpd_conf_io.puts ssl_vhost_config
domain_httpd_conf_io.puts "</VirtualHost>"
rescue SystemCallError => err
logErr "ERROR: Unexpected error: "+err
domain_httpd_conf_io.close
end
Still has some bugs to work out but it mostly does what I want.

No clue, but one thing that may help you is apache's support for mass virtual hosting: http://httpd.apache.org/docs/2.2/vhosts/mass.html
If you can enforce consistency across your vhosts then maybe you don't need ruby to create/manage/edit them. Convention over configuration is the rails way right?

I would love to. Sadly what I'm trying to do is fix an issue with Virtualmin, which generates VirtualHosts which are lacking: http://serverfault.com/questions/121313/virtualmin-automatically-create-ssl-based-website-with-a-shared-ssl-wildcard-cer – Josh Mar 12 '10 at 20:31
