[Puppet Users] Question about service subscribe and line editing.
Hello guys, sorry if this is basic, but i cant find a answer.
i have the following code:
# services/syslog.pp
import "../utils.pp"
class syslog {
file{"/etc/syslog.conf": ensure => present}
line{ redir_logs:
file => "/etc/syslog.conf",
line => ''*.* @ syslog.domain.com'';
}
service { syslog:
ensure => running,
subscribe => File["/etc/syslog.conf"]
}
}
Im using the "Simple text edit" recipe.
I can see that the line is added, but the service is not restarted. How does
suscribe work?, if i replace completely the file, it restarts, but not if i
edit a line. Is there workaround?, this is my 3rd day with puppet, so im on
the first phase of the learning curve, but im moving forward!
cheers!

While this probably isn''t what you want, exactly, you might want to look into ''templates''. Where possible it''s always cleaner to write a template for something like syslog.conf, and have that generated for each node, than to try and replace lines within it!

Nicholas- Yeah that learning curve can be right pain. I am on about week 4. th language is easy enough but there are some many way so to but it to gether.

I have not gotten that far yet on my learning curve.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On Saturday 29 March 2008, Nicolas Arias wrote:> Thanks DavidS, ill check the template thing (i dont really see how can it > make my life easy in this manifest, but ill give it a try)Usually "line" is only for files which are regularily modified by processes outside of puppet''s control. Files like syslog.conf should be managed completely by puppet though. This enables you to just say it like this: file { "/etc/syslog.conf": mode => 0644, owner => root, group => root, content => "*.* @mysyslogserver\n" } This would also disable (presumably) unneeded local logs and make subscribe work without needing to checksum the file. Using templates you can expand on this, by saying content => template ("mysyslog.conf") where you can have arbitrary text and ruby code to create complex syslog configs.
