[chef] Re: What is the best way to change a field of a conf file in centos

Mike's solution is the least obtrusive, but if other cookbook authors are good citizens, they'll be using the sysctl cookbook to edit that file as well.

There is a cookbook for managing sysctl: http://community.opscode.com/cookbooks/sysctl

You best bet is to depend on and include that cookbook, and then either use node.default['sysctl']['params']['net']['ipv4']['ip_nonlocal_bind'] = 1

or the LWRP:

sysctl_param 'net.ipv4.ip_nonlocal_bind' do
  value 1
end

Hi,

I am trying to change a field (here is "net.ipv4.ip_nonlocal_bind=1") of the file /etc/sysctl.conf, currently I am using template to change the field, however someone complained that it was not good to template the system file ''sysctl.conf', because it may also used by other cookbooks. I agreed with that guy, it is definitely better to only change a specific field instead of the whole file with respect to a system file.

I am wondering what is the best way to change a specific field of a config file in Chef.
It will be much appreciated if someone can give me some hints and share some opinions.

Thanks,

Sam
