Puppet users - Sep 2012 - Nagios and www-data users.

I''m sure people have hit this problem before. In my nagios module, the
nagios command pipe file at /var/lib/nagios3/rw/nagios.cmd is owned by
the nagios user, but needs to be written to by the www-data user.
Adding the www-user to the nagios group is one solution, but that
requires that the nagios module potentially modify the www-data user,
which seems bad.

What''s the best way to do this? I tried to explicitly define the
www-data user in it''s own class, and then create another nagios class
that inherits from that so that I could do plusignment, but I
obviously have the syntax wrong. Puppet doesn''t like this.

class nagios::users inherits users::www-data {
     User[''www-data''] { group +>
[''nagios''] }
}

There should be a "nagcmd" group which both nagios and your apache
user are members of. The nagios.cmd pipe should have permission of
0660 and ownership of nagios:nagcmd. If you were using check_mk
livestatus then the livestatus.cmd socket would have the same perms
and ownership.

Usually this is taken care of by the nagios packages.
