如何在puppet中运行sudo命令作为exec资源

我一直试图将sudo命令作为exec资源运行而没有运气。首先我得到了#34;对不起,你必须有一个tty来运行sudo"消息,我现在得到"没有tty存在且没有指定askpass程序"。这就是@ i目前正在运行的目的:

[dan@kyvltvm00022 tests]$ puppet apply ./test.pp 
Notice: Compiled catalog for kyvltvm00022.bfredb.com in environment production in 0.07 seconds
Notice: /Stage[main]/Main/Exec[testing sudo]/returns: sudo: no tty present and no askpass program specified
Error: /usr/bin/sudo su - fred -c "/usr/bin/echo \"hola dan\" > /home/fred/unaprueba" returned 1 instead of one of [0]

Notice: Finished catalog run in 0.13 seconds
[dan@kyvltvm00022 tests]$ cat ./test.pp 
exec { 'testing sudo':
  command => '/usr/bin/sudo su - fred -c "/usr/bin/echo \"hola dan\" > /home/fred/unaprueba"',
}
[dan@kyvltvm00022 tests]$ sudo cat /etc/sudoers
## Sudoers allows particular users to run various commands as
## the root user, without needing the root password.
##
## Examples are provided at the bottom of the file for collections
## of related commands, which can then be delegated out to particular
## users or groups.
## 
## This file must be edited with the 'visudo' command.

## Host Aliases
## Groups of machines. You may prefer to use hostnames (perhaps using 
## wildcards for entire domains) or IP addresses instead.
# Host_Alias     FILESERVERS = fs1, fs2
# Host_Alias     MAILSERVERS = smtp, smtp2

## User Aliases
## These aren't often necessary, as you can use regular groups
## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname 
## rather than USERALIAS
# User_Alias ADMINS = jsmith, mikem


## Command Aliases
## These are groups of related commands...

## Networking
# Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool

## Installation and management of software
# Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum

## Services
# Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig

## Updating the locate database
# Cmnd_Alias LOCATE = /usr/bin/updatedb

## Storage
# Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount

## Delegating permissions
# Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp 

## Processes
# Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall

## Drivers
# Cmnd_Alias DRIVERS = /sbin/modprobe

# Defaults specification
#Cmnd_Alias NOTTYCMD = /usr/bin/echo "hola dan" > /home/fred/unaprueba

#
# Disable "ssh hostname sudo <cmd>", because it will show the password in clear. 
#         You have to run "ssh -t hostname sudo <cmd>".
#
#Defaults   requiretty

Defaults    env_reset
Defaults    env_keep =  "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults    env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults    env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults    env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults    env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin

## Next comes the main part: which users can run what software on 
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
##  user    MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere 
root    ALL=(ALL)   ALL
dan ALL=(ALL)   NOPASSWD: ALL
#puppet ALL=(ALL)   NOPASSWD: ALL
#dan    ALL=(ALL)   NOPASSWD: /usr/bin/su -fred -c *

## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)   ALL

## Same thing without a password
# %wheel    ALL=(ALL)   NOPASSWD: ALL

## Allows members of the users group to mount and unmount the 
## cdrom as root
# %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom

## Allows members of the users group to shutdown this system
# %users  localhost=/sbin/shutdown -h now

## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
#includedir /etc/sudoers.d

任何有关如何实现这一目标的帮助或想法都将非常有用。

要以非交互方式使用sudo,调用用户需要NOPASSWD:

中的sudoers条目
%wheel    ALL=(fred) NOPASSWD: /usr/bin/echo "hola dan"

然后

sudo -u fred /usr/bin/echo "hola dan"

请注意,我使用sudo -u支持sudo su -

除此之外,Puppet实际上部署了exec资源可以调用的包装脚本是一种很好的做法,当它们注意到它们以root用户身份运行时会自行删除它们的特权。如果它让您感觉更安全,则可以通过su -u <user>调用它们,这仍然比基于sudo的方法更简单,因为您的Puppet代理在任何情况下都应该以{{1​​}}运行。
