Installs logrotate package and provides a resource for managing logrotate configs
cookbook 'logrotate', '= 1.2.2', :supermarket
knife supermarket install logrotate
knife supermarket download logrotate
Description
Manages the logrotate package and provides a definition to manage
application specific logrotate configuration.
Requirements
Should work on any platform that includes a 'logrotate' package and
writes logrotate configuration to /etc/logrotate.d. Tested on Ubuntu,
Debian and Red Hat/CentOS.
Recipes
logrotate::global
Generates and controls a global /etc/logrotate.conf
file that will include
additional files generated by the logrotate_app
definition (see below). The
contents of the configuration file is controlled through node attributes under
node['logrotate']['global']
. The default attributes are based on the
configuration from the Ubuntu logrotate package.
To define a valueless directive (e.g. compress
, copy
) simply add an attribute
named for the directive with a truthy value :
node['logrotate']['global']['compress'] = 'any value here'
Note that defining a valueless directive with a falsey value will not make it
false, but will remove it:
# Removes a defaulted 'compress' directive; does not add a 'nocompress' directive. node.override['logrotate']['global']['compress'] = false
To fully overrride a booleanish directive like compress
, you should probably
remove the positive form and add the negative form:
node.override['logrotate']['global']['compress'] = false node.override['logrotate']['global']['nocompress'] = true
The same is true of frequency directives; to be certain the frequency directive
you want is included in the global configuration, you should override the ones
you don't want as false:
%w[ daily, weekly, yearly ].do |freq| node.override['logrotate']['global'][freq] = false end node.override['logrotate']['global']['monthly'] = true
To define a parameter with a value (e.g. create
, mail
) add an attribute
with the desired value:
node['logrotate']['global']['create'] = '0644 root adm'
To define a path stanza in the global configuration (generally unneeded because
of the logrotate_app
definition) just add an attribute with the path as the
name and a hash containing directives and parameters as described above:
node['logrotate']['global']['/var/log/wtmp'] = { 'missingok' => true, 'monthly' => true, 'create' => '0660 root utmp', 'rotate' => 1 }
firstaction
, prerotate
, postrotate
, and lastaction
scripts can be defined either
as arrays of the lines to put in the script or multiline strings:
node['logrotate']['global']['/var/log/foo/*.log'] = { 'missingok' => true, 'monthly' => true, 'create' => '0660 root adm', 'rotate' => 1, 'prerotate' => [ 'service foo start_rotate', 'logger started foo service log rotation' ], 'postrotate' => <<-EOF service foo end_rotate logger completed foo service log rotation EOF }
Definitions
logrotate_app
This definition can be used to drop off customized logrotate config
files on a per application basis.
The definition takes the following params:
- path: specifies a single path (string) or multiple paths (array) that should have logrotation stanzas created in the config file. No default, this must be specified.
- enable: true/false, if true it will create the template in /etc/logrotate.d.
- frequency: sets the frequency for rotation. Default value is 'weekly'. Valid values are: daily, weekly, monthly, yearly, see the logrotate man page for more information.
- size: Log files are rotated when they grow bigger than size bytes.
- template: sets the template source, default is "logrotate.erb".
- cookbook: select the template source from the specified cookbook. By default it will use the cookbook where the definition is used.
- create: creation parameters for the logrotate "create" config, follows the form "mode owner group". This is an optional parameter, and is nil by default.
- postrotate: lines to be executed after the log file is rotated
- prerotate: lines to be executed after the log file is rotated
- sharedscripts: if true, the sharedscripts options is specified which makes sure prescript and postscript commands are run only once (even if multiple files match the path)
See USAGE below.
USAGE
The default recipe will ensure logrotate is always up to date.
To create application specific logrotate configs, use the
logrotate_app
definition. For example, to rotate logs for a tomcat
application named myapp that writes its log file to
/var/log/tomcat/myapp.log:
logrotate_app "tomcat-myapp" do
cookbook "logrotate"
path "/var/log/tomcat/myapp.log"
frequency "daily"
rotate 30
create "644 root adm"
end
To rotate multiple logfile paths, specify the path as an array:
logrotate_app "tomcat-myapp" do
cookbook "logrotate"
path [ "/var/log/tomcat/myapp.log", "/opt/local/tomcat/catalina.out" ]
frequency "daily"
create "644 root adm"
rotate 7
end
To specify which logrotate options, specify the options as an array:
logrotate_app "tomcat-myapp" do
cookbook "logrotate"
path "/var/log/tomcat/myapp.log"
options ["missingok", "delaycompress", "notifempty"]
frequency "daily"
rotate 30
create "644 root adm"
end
