Puppet filebucket命令参数介绍(九)

puppet filebucket命令通常用来做文件的备份、获取和还原,支持远程操作.
puppet 节点会在每次更新之前，将该节点运行的环境配置文件以md5的形式存储到/var/lib/puppet/bucket目录,里面包含了每个配置文件的内容、路径和名称，通过filebucket命令指定文件的md5值可将指定文件恢复.
puppet filebucket参数:

[root@puppet ~]# puppet filebucket -h
puppet-filebucket(8) -- Store and retrieve files in a filebucket
========
SYNOPSIS
--------
A stand-alone Puppet filebucket client.
USAGE
-----
puppet filebucket <mode> [-h|--help] [-V|--version] [-d|--debug]
[-v|--verbose] [-l|--local] [-r|--remote] [-s|--server <server>]
[-b|--bucket <directory>] <file> <file> ...
Puppet filebucket can operate in three modes, with only one mode per call:
backup:
Send one or more files to the specified file bucket. Each sent file is
printed with its resulting md5 sum.
get:
Return the text associated with an md5 sum. The text is printed to
stdout, and only one file can be retrieved at a time.
restore:
Given a file path and an md5 sum, store the content associated with
the sum into the specified file path. You can specify an entirely new
path to this argument; you are not restricted to restoring the content
to its original location.
DESCRIPTION
-----------
This is a stand-alone filebucket client for sending files to a local or
central filebucket.
Note that 'filebucket' defaults to using a network-based filebucket
available on the server named 'puppet'. To use this, you'll have to be
running as a user with valid Puppet certificates. Alternatively, you can
use your local file bucket by specifying '--local'.
OPTIONS
-------
Note that any setting that's valid in the configuration
file is also a valid long argument. For example, 'ssldir' is a valid
setting, so you can specify '--ssldir <directory>' as an
argument.
See the configuration file documentation at http://docs.puppetlabs.com/references/stable/configuration.html for the
full list of acceptable parameters. A commented list of all
configuration options can also be generated by running puppet with
'--genconfig'.
* --debug:    #开启debug调试模式
Enable full debugging.
* --help:
Print this help message
* --local:    #使用本地的filebucket，这将使用默认配置.
Use the local filebucket. This will use the default configuration
information.
* --remote:    #使用远程的filebucket,将使用默认配置信息.
Use a remote filebucket. This will use the default configuration
information.
* --server:    #使用服务器发送的文件而不是局部(agent)。
The server to send the file to, instead of locally.
* --verbose:
Print extra information.
* --version:
Print version information.
EXAMPLE
-------
$ puppet filebucket backup /etc/passwd
/etc/passwd: 429b225650b912a2ee067b0a4cf1e949
$ puppet filebucket restore /tmp/passwd 429b225650b912a2ee067b0a4cf1e949

扩展命令:puppet file 不常用.
在sh-proxy2 agent端通过md5方式下载sh-web1 agent的备份文件.

[root@sh-proxy2 puppet]# puppet file download {md5}1e8d610ffbe27bf880c7d734386dbde1
Notice: Saved {md5}1e8d610ffbe27bf880c7d734386dbde1 to filebucket
