sysctl2 Cookbook
A cookbook to configure kernel parameters on a system. It supports configuring files in /etc/sysctl.d, and in /etc/sysctl.conf directly (mainly to support RHEL/CentOS 5 & 6).
Requirements
Ruby 1.9 or later
Should support any linux platform, but has been tested successfully on:
- rhel >= 5.0
- centos >= 5.0
- ubuntu >= 12.04
- fedora >= 17.0
Attributes
sysctl2::default
['sysctl']['conf_dir']
Type: String
Description: The directory where the config file is located
Default: /etc/sysctl.d['sysctl']['conf_file']
Type: String
Description: The config file name
Default: 999-chef-sysctl.conf
Usage
sysctl2::default
Set attributes in the sysctl/params namespace to configure kernel parameters. Example values:
node.set['sysctl']['params']['kernel.sysrq'] = 0
node.set['sysctl']['params']['net.ipv4.ip_local_port_range'] = '30000 65000'
Then, just include sysctl2 in your node's run_list:
{
"name":"my_node",
"run_list": [
"recipe[sysctl2]"
]
}
For platforms that don't support setting parameters via files in the /etc/sysctl.d directory (RHEL/CentOS 6 and lower), setting the sysctl/conf_dir attribute to '/etc' and the sysctl/conf_file attribute to 'sysctl.conf' will allow you to set kernel parameters in the correct/expected location for that platform. Unfortunatly, that also means that you'll need to be aware of kernel parameter changes in other recipies, and be sure to include them in your attribute list, in order to not miss them.
The default sysctl/conf_file attribute value gives us a reasonable chance of being the last config file applied. The files are processed according to their ASCII sort order, so there is still room to add more files to be processed after the recipe default file by naming the config file with leading character prefixes (ex. zzz-last.conf).
