split httpd in smaller files

Question

Hi I need to extract each VirtualHosts from my httpd.conf to separate files for easier management.

Original httpd.conf .

..
<VirtualHost *:XXXX>
  SuexecUserGroup user1 groupX
  ...
</VirtualHost>
<VirtualHost *:XXXY>
  SuexecUserGroup user2 groupY
  ...
</VirtualHost>
<VirtualHost *:XXYY>
  SuexecUserGroup user3 groupZ
  ...
</VirtualHost>
...

And I would like to have files like: - XXXX_user1.conf containing:

Listen XXXX
<VirtualHost *:XXXX>
  SuexecUserGroup user1 groupX
  ...
</VirtualHost>

- XXXY_user2.conf containing:

Listen XXXY
<VirtualHost *:XXXY>
  SuexecUserGroup user2 groupY
  ...
</VirtualHost>

Sounds a bit complicated but I have like 500 to do by hand ;(

Many thanks for answers

Give this a try:

#!/usr/bin/gawk -f
BEGIN {
    RS = "</VirtualHost>\n"
}
{
    prefix = gensub("*:([^>]*)>", "\\1", "1", $2)
    filename = prefix "_" $4 ".conf"
    print "Listen " prefix "\n" $0 "\n" RS > filename
}

Save it in a file named, perhaps, "httpdsplit" and do:

$ chmod u+x httpdsplit
$ ./httpdsplit httpd.conf

Though you didn't mention it, this looks like apache httpd.conf. Though I recommend the existing answer which splits the files, there is another option.

If the apache server is built with mod_perl and if you know (or are willing to learn) Perl, remember that mod_perl binds with all aspects of apache, including config. You could write the config with a Perl stanza and generate the VirtualHost config within perl itself.
