作用：通过SSH模块管理客户端的ssh远程服务，并用key认证方式替代密码认证方式，提高安全性；
本例分两阶段，首先是ssh的安装、配置及服务管理，然后是使用如何转换成key认证方式。
#第一阶段
1、服务端配置ssh模块
（1）模块清单
[root@puppet ~]# tree /etc/puppet/modules/ssh/ /etc/puppet/modules/yum/ ├── files │ └── sshd_config ├── manifests │ ├── config.pp │ ├── init.pp │ ├── install.pp │ ├── params.pp │ ├── key.pp │ └── service.pp └── templates
（2）定义参数类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/params.pp
class ssh::params {
case $operatingsystem { #条件判断，根据操作系统来定义同名参数不同的值
Solaris: {
$ssh_package_name = ‘openssh‘
$ssh_service_config = ‘/etc/ssh/sshd_config‘
$ssh_service_name = ‘sshd‘
}
/(RedHat|CentOS|Fedora|Ubuntu|Debian)/: {
$ssh_package_name = ‘openssh-server‘
$ssh_service_config = ‘/etc/ssh/sshd_config‘
$ssh_service_name = ‘sshd‘
}
default: {
fail("Module ssh is not supported on ${::operatingsystem}")
}
}
}（3）定义安装类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/install.pp
class ssh::install {
package { ssh::params::ssh_package_name:
ensure => installed,
}
}（4）定义配置类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/config.pp
class ssh::config {
file { ssh::params::ssh_service_config:
ensure => present,
owner => ‘root‘,
group => ‘root‘,
mode => 0600,
source => "puppet:///modules/ssh/sshd_config",
require => Class["ssh::install"],
notify => Class["ssh::service"],
}
}（5）定义服务类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/service.pp
class ssh::service {
service { ssh::params::ssh_service_name:
ensure => running,
hasstatus => true,
hasrestart => true,
enable => true,
require => Class["ssh::config"],
}
}（7）定义ssh主类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/init.pp
class ssh {
include ssh::params
include ssh::install,ssh::config,ssh::service
}（8）定义节点文件，调用模块
[root@puppet ~]# vi /etc/puppet/manifests/centostest.pp
node "centostest.ewin.com" {
include ntp, yum, puppet, host, ssh
}（9）应用节点文件
[root@puppet ~]# vi /etc/puppet/manifests/site.pp import "centostest.pp"
（10）复制配置文件
复制一份SSH的配置文件（/etc/ssh/sshd_config）到puppet的目录下（/etc/puppet/modules/ssh/files/sshd_config），并在文件顶部插入一条注释说明:
### config by puppet ###
2、测试第一阶段
（1）客户端运行puppet agent -t，同时观察日志
[root@centostest ~]# tailf /var/log/messages
Nov 12 10:56:08 centostest puppet-agent[39921]: (/Stage[main]/Ssh::Config/File[/etc/ssh/sshd_config]/content) content changed ‘{md5}53ad75eb1f2269d23f6e4228353cbca3‘ to ‘{md5}a271889f546ff10b7af311ba35ed5e1c‘
Nov 12 10:56:09 centostest puppet-agent[39921]: (/Stage[main]/Ssh::Service/Service[sshd]) Triggered ‘refresh‘ from 1 events
Nov 12 10:56:09 centostest puppet-agent[39921]: Finished catalog run in 2.59 seconds结论：配置文件更新，服务类刷新了一次，ssh的基本管理配置成功
（2）服务端通过ssh远程客户端
[root@puppet ~]# ls /root/.ssh/ #查看密钥目录 [root@puppet ~]# ssh centostest.ewin.com #Ssh远程连接，可以用IP地址 The authenticity of host ‘centostest.ewin.com (10.188.1.85)‘ can t be established. RSA key fingerprint is 0d:79:7b:52:6c:8a:0c:cf:95:8e:f7:25:b4:95:98:c8. Are you sure you want to continue connecting (yes/no)? yes #输入yes确认连接 Warning: Permanently added ‘centostest.ewin.com,10.188.1.85‘ (RSA) to the list of known hosts. #添加到known_hosts列表中 root@centostest.ewin.com s password: #输入客户端centostest的root用户的密码 Last login: Wed Nov 12 10:52:34 2014 from ywzhou-pc.ewin.com #记录的最后一次登陆记录
结论：第一次通过ssh连接客户端会创建主机密钥并记录到known_hosts，提示输入root密码，这便是最常用的密码认证方式。
[root@centostest ~]# exit #退出ssh连接，返回到puppet服务器 logout Connection to centostest.ewin.com closed. [root@puppet ~]# ls /root/.ssh/ #再次查看密钥目录，出现了生成的记录文件 known_hosts [root@puppet ~]# ssh centostest.ewin.com #重新远程连接客户端，不再确认密钥 root@centostest.ewin.com‘‘s password: Last login: Wed Nov 12 11:06:36 2014 from puppet.ewin.com
结论：第二次连接会读取known_hosts中记录的主机密钥，只需输入root密码后即可连接
#第二阶段
说明：sshkey认证方式可以在linux服务器上（如puppet服务器）生成密钥，通过puppet服务器ssh到客户端进行管理；也可以在windows机器上使用连接管理工具（如Xshell 4或SecureCRT）生成密钥，这也是运维人员常用的软件；sshkey认证方式可以安全的、无需密码的、快速的连接客户端进行管理；
先介绍如何在puppet服务器上生成无密码的密钥（私钥和公钥一对），将公钥分发到客户端，关闭ssh的password认证连接。
3、使用ssh-keygen命令生成认证密钥
(1)服务端生成密钥
[root@puppet ~]# ssh-keygen -t dsa Generating public/private dsa key pair. Enter file in which to save the key (/root/.ssh/id_dsa): #私钥保存路径 Enter passphrase (empty for no passphrase): #输入一个密语字符串，这里可以直接回车，空密码 Enter same passphrase again: Your identification has been saved in /root/.ssh/id_dsa. #私钥 Your public key has been saved in /root/.ssh/id_dsa.pub. #公钥 The key fingerprint is: af:eb:5a:45:a7:91:dc:80:6e:03:75:ec:71:ae:2d:a0 root@centostest.ewin.com
参数说明：-t表示密钥类型，dsa或rsa，都是SSH2的，不支持SSH1；后面还可接-C "puppet test sshkey"表示注释，用来标示密钥的用途。
（3）查看生成的密钥
[root@puppet ~]# ls /root/.ssh/ id_dsa id_dsa.pub known_hosts
说明：三个文件分别是私钥、共钥、已连接过的SSH客户端密钥记录，下面来查看密钥文件：
[root@centostest ~]# cat /root/.ssh/id_dsa -----BEGIN DSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,AB0A77C490AD5CE6 LCpOrQ8tKnAzDW1efWEB5AB2BXbnGUJLxKNpiwqyxR96XGVQEjgzqQwcjB6GJLI5 HUCW8JpS5IqdegJgsY76QRE4PD9XRiZRWEhaP+9v0NMFGF6lU93ahrk5DR3Jmpgx jhJEPZTCSB889SaGhz+E89BOrxjRDootyiyYOjlwekvHQPJ0nrMt27shMYJ4apym tXahjdlwlbzJzrONhq9eMklmZnfy/l8VdiDnVcUUIQMLN5IPZBcJiqFGUbLMspI3 E5zBI7jGcF/QYeOv7IeK8cjaZ8AwBznZOnOB9HUEBuwDAFS/Q6urAaeri2XvVgBy 1AcGljNZCfM4ltogNGzrZeVydtcqQstEPjCr8bpWkN4eq+PvXw3eA/5WkDaLpX88 qt8EkZ3HMa1zu2pRZ5iCG4z2rTxO9vFUXJnU+Un720jGYTEihWDycEiOco0brCgt eQt8fwnbNO/GmQCeX5UeoGo92zqYMKUosHx65Kx+kmaxfAmaL7GPszCM3D9NgqY9 L6+eEyVyLaNecmD+ishPAFsyqA0pfIJClsNNQXYHL1Mbm5ADCAjfiguJjQZBzQt1 l8zSc6dCxaKgZoQ+epmjGjN5jbyXcqER -----END DSA PRIVATE KEY-----

说明：将公钥文件id_dsa.pub中的三段（类型、密钥编码、用户）定义到密钥类中
（4）定义密钥类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/key.pp
class ssh::key {
ssh_authorized_key { "puppet": #管理机的主机名，也是公钥名，不重复就行
ensure => present, #基础属性，指定key是否生成，present、absent
type => "ssh-dss", #key的加密类型
key => "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", #生成的密钥值，一般是十六进制数字的长字符串
target => "/root/.ssh/authorized_keys", #存储的SSH密钥文件的路径
user => ‘root‘, #指定是哪个用户（客户端）的key
require => Class["ssh::install"],
}
}说明：可以使用puppet的user资源定义一个用户来分配sshkey，常用于多级系统管理员的IT部门。
（5）定义ssh主类
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/init.pp
class ssh {
include ssh::params
include ssh::install, ssh::config, ssh::service, ssh::key
}（6）定义节点文件，调用模块
[root@puppet ~]# vi /etc/puppet/manifests/centostest.pp
node "centostest.ewin.com" {
include ntp, yum, puppet, host, ssh
}（7）应用节点文件
[root@puppet ~]# vi /etc/puppet/manifests/site.pp import "centostest.pp"
（8）修改ssh配置文件
[root@puppet ~]# vi /etc/puppet/modules/ssh/files/sshd_config PasswordAuthentication no #关闭密码认证
4、测试第二阶段
（1）客户端运行puppet agent -t，同时观察日志
[root@centostest ~]# tailf /var/log/messages
Nov 12 11:39:39 centostest puppet-agent[28301]: (/Stage[main]/Ssh::Config/File[/etc/ssh/sshd_config]/content) content changed ‘{md5}a271889f546ff10b7af311ba35ed5e1c‘ to ‘{md5}1983ed7e2956b9bd4c627e45906b193e‘
Nov 12 11:39:39 centostest puppet-agent[28301]: (/Stage[main]/Ssh::Service/Service[sshd]) Triggered ‘refresh‘ from 1 events
Nov 12 11:39:49 centostest puppet-agent[28534]: (/Stage[main]/Ssh::Key/Ssh_authorized_key[puppet]/ensure) created结论：更新了配置文件、重启了服务、创建了密钥记录文件
（2）服务端通过ssh远程客户端
[root@puppet ~]# ssh centostest.ewin.com Last login: Wed Nov 12 11:08:49 2014 from puppet.ewin.com [root@centostest ~]#
结论：使用密钥认证方式连接，无需输入密码直接就连接上了
（3）查看客户端生成的密钥文件
[root@centostest ~]# cat /root/.ssh/authorized_keys # HEADER: This file was autogenerated at Tue Nov 12 11:39:49 +0800 2014 # HEADER: by puppet. While it can still be managed manually, it # HEADER: is definitely not recommended. ssh-dss AAAAB3NzaC1kc3MAAACBAJrukh4ukPZ75uQEtLdczpv9RrjJDAY15wtJt VBtl1bUNxOdUiE3hlcqBRMrU01bokdz6LZQgy7j24k11/dS5ojawzkC9J5a4q4tBu 3geasmmg+sd1GcC/mAYumCg2YzVGlsrUwbzgU62m7+FZSej0ySGORoaGcHLxdrpy2 4A5qbAAAAFQDt4RpHlMCV2bv2/kLcCZdI416S3QAAAIEAl2P8cZgSYRbO2pGMTp4w P7jfq/1EXq/+kNa4SpEpUT/qQbfLUSNSEcKMsQKGSiDih4AzTfTPxHf4UGwfB/Cxv 9WdYEALrImE3KvETsY561u7UcgBLQkqLJsJLHp/q4qCLkgLfiohzn2aQKivtgqUCr Q9wAZUhW9FUZwskVWM884AAACAclP+RlLbblUL5eTzq4DEpOtWKbX5UXXwxoOyrc5 ADS6NtM9D3jyB/pJ/Oiz4uU33J810EmYJLkPTph0FKk94MiCkQLg6zaoV9Ljlbw2B S46YzdEv5bCKjqaW9jIh+o/PnfF8kGRyIImGLce6SasGhRqkm6E3z2djBMtA/u9TZ ok= puppet
结论：可以看到客户端的认证密钥文件中成功记录了前面生成的公钥；通过头部注释信息可以看到是由puppet部署的。另外如果不是指定root用户，就在/home/<user_name>/.ssh中查找。
注意：authorized_keys中只会保存由puppet的ssh_authorized_key部署的公钥，其他的自动删除。
（4）其他服务端访问测试
[root@zabbix ~]# ssh 10.188.1.85 The authenticity of host ‘10.188.1.85 (10.188.1.85)‘ cant be established. RSA key fingerprint is 0d:79:7b:52:6c:8a:0c:cf:95:8e:f7:25:b4:95:98:c8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘10.188.1.85‘ (RSA) to the list of known hosts. Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
结论：可以看到Permission denied权限拒绝，无法登陆，密码认证方式被关闭了，成功转换到KEY认证。
#扩展阶段
说明：添加一台管理机公钥，在windows系统下使用工具进行sshkey认证连接。
5、生成认证密钥
（1）使用Xshell创建用户密钥
说明：密码可以为空
（2）使用SecureCRT创建用户密钥
说明：进入KEY的目录，用记事本打开Identity.pub查看公钥信息
（3）将公钥注册页面上的信息添加到密钥类文件中
[root@puppet ~]# vi /etc/puppet/modules/ssh/manifests/key.pp
class ssh::key {
ssh_authorized_key { "puppet":
ensure => present,
type => "ssh-dss",
key => "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",
target => "/root/.ssh/authorized_keys",
user => ‘root‘,
require => Class["ssh::install"],
}
#添加ywzhou-pc的公钥资源
ssh_authorized_key { "ywzhou-pc":
ensure => present,
type => "ssh-dss",

}
}6、测试扩展阶段
（1）客户端运行puppet agent -t，同时查看日志
[root@centostest ~]# tailf /var/log/messages Nov 12 12:17:30 centostest puppet-agent[10082]: (/Stage[main]/Ssh::Key/Ssh_authorized_key[ywzhou-pc]/ensure) created
（2）客户端查看公钥记录文件
[root@centostest ~]# cat /root/.ssh/authorized_keys # HEADER: This file was autogenerated at Wed Nov 12 12:17:30 +0800 2014 # HEADER: by puppet.

（3）window管理机使用Xshell工具连接客户端
说明：因为设置的是空密码，直接回车即可连接。
（4）window管理机使用SecureCRT工具连接客户端
说明：因为没有在puppet中定义SecureCRT的公钥，因此认证失败，如何添加自己尝试。
7、ssh资源（sshkey和ssh_authorized_key）
（1）sshkey资源
说明：sshkey资源负责如何安装key到/etc/ssh/ssh_known_hosts，不能管理用户的授权密钥，因此不常用。
sshkey { ‘resource title‘:
name => #密钥相关的主机名
ensure => #基本属性，present, absent
host_aliases => #主机别名，支持数组表示多个别名
key => #密钥，通常是一长串编码字符窜
target => #存储SSH密钥的文件
type => #SSH类型，ssh-dss (dsa), ssh-ed25519 (ed25519), ssh-rsa (rsa),
#ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521
}（2）ssh_authorized_key资源
说明：ssh_authorized_key资源负责管理授权密钥，大部分都使用这个资源类型
ssh_authorized_key { ‘resource title‘:
name => "hostname", #主机名
ensure => present, #基础属性，指定key是否生成，present、absent
type => "ssh-dss", #key生成的加密类型，ssh-dsa或ssh-rsa
key => "密钥值", #生成的密钥值，一般是十六进制数字的长字符串
target => "/home/sky/.ssh/authorized_keys", #存储的SSH密钥文件的路径
user => ‘sky‘, #指定是哪个用户的key
options => , #其他选项
}（3）官方例子
#查看密钥字符串

#翻译成SSH密钥资源
ssh_authorized_key { ‘nick@magpie.puppetlabs.lan‘:
