puppet系列之sudo模塊

 需求：每臺服務器上都創建dev組，專門給開發人員，給特定的開發人員建賬號，並加入dev組；

運維人員也將創建各自的用戶，並加入wheel組，通過sudo來對組裏成員做權限設置。

 

架構如下：

 

manfests裏面的文件內容如下：

1,init.pp
class sudo {
  case $::osfamily {
    'RedHat': {
      include "sudo::conf"
      import 'sudoers.pp'
    }
    default: {
      fail("$::osfamily not yet supported by the 'sudo' module!")
    }
  }
}

2,conf.pp
class sudo::conf {
  package { "sudo":
    ensure => present,
  }

  # Source the sudoers file from the Puppet Master
  file { "/etc/sudoers":
    ensure  => present,
    owner   => 'root',
    group   => 'root',
    mode    => 0440,
    source  => "puppet:///modules/sudo/sudoers",
    require => Package["sudo"],
  }

  # Source a new 'su' file for PAM (caution: this may be platform-specific)
  file { "/etc/pam.d/su":
    ensure => present,
    owner  => 'root',
    group  => 'root',
    mode   => 0644,
    source => "puppet:///modules/sudo/pam_su_el6"
  }

  # Clear any config in sudoers.d
  file { "/etc/sudoers.d":
    ensure  => directory,
    owner   => 'root',
    group   => 'root',
    mode    => '0750',
    recurse => true,
    purge   => true,
    require => Package["sudo"],
  }
}

3,sudoers.pp
define sudo::sudoers (
  $sudo_sudoers ,
  $sudo_sysadmins ,
 # $admins   = split($sudo_sysadmins, ','),
 # $sudoers  = split($sudo_sudoers, ','),
)
{
  user { [ $sudo_sysadmins ]:
    ensure  => present,
    groups  => ['wheel'],
    require => Group['wheel'],
  }

  user { [ $sudo_sudoers ]:
    ensure  => present,
    groups  => ['dev'],
    require => Group['dev'],
  }

  group { "wheel":
    ensure => present,
  }

  group { "dev":
    ensure => present,
  }
}

files目錄文件內容如下：

1,pam_su_el6
#%PAM-1.0
# This file is managed by Puppet.
#
auth        sufficient  pam_rootok.so
# Uncomment the following line to implicitly trust users in the "wheel" group.
#auth       sufficient  pam_wheel.so trust use_uid
# Uncomment the following line to require a user to be in the "wheel" group.
auth        required    pam_wheel.so use_uid
auth        include     system-auth
account     sufficient  pam_succeed_if.so uid = 0 use_uid quiet
account     include     system-auth
password    include     system-auth
session     include     system-auth
session     optional    pam_xauth.so

2,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 (perhap 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

## Denied commands for dev
Cmnd_Alias DEV_DENIED = /bin/su, /usr/sbin/visudo, /bin/chgrp, /usr/sbin/adduser, /usr/sbin/useradd, /usr/sbin/usermod, /usr/sbin/userdel, /usr/sbin/passwd, /sbin/shutdown, /sbin/init, /sbin/reboot, /usr/bin/reboot

# Defaults specification

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

#
# Refuse to run if unable to disable echo on the tty. This setting should also be
# changed in order to be able to use sudo without a tty. See requiretty above.
#
Defaults   !visiblepw

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

## 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

## 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

## Denied DEV_DENIED and STORAGE commands for dev group
%dev     ALL=(ALL)       ALL, !DEV_DENIED, !STORAGE

使用方法如下：

include sudo
sudo::sudoers { "example":
  sudo_sysadmins => ['test-wheel-1','test-wheel-2'],
  sudo_sudoers   => ['test-sudo-1'],
}
