Puppet 安装与配置

在RHEL6.5上安装puppet

10.1.1.33  puppet 服务端     主机名 puppet.domain.com

10.1.1.34  puppet 客户端     主机名 agent.domain.com

各机器/etc/hosts配置为:

10.1.1.33 puppet.domain.com
10.1.1.34 agent.domain.com

主机名:

[email protected]:nodes# cat /etc/sysconfig/network-scripts/ifcfg-eth0
...
HOSTNAME=puppet.domain.com

[email protected]:puppet# cat /etc/sysconfig/network-scripts/ifcfg-eth0
....
HOSTNAME=agent.domain.com

确认安装ruby相关包    

yum -y install ruby ruby-libs ruby-shadow

检查ruby版本(1.85以后版本)

[email protected]:~# ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]

根据操作系统版本,这里是centos6.5,选择puppetlabs-release-6-5软件包:

rpm -Uvh http://yum.puppetlabs.com/el/6.5/products/x86_64/puppetlabs-release-6-5.noarch.rpm
yum clean all

在服务端安装puppet.会自动安装facter等相关依赖包

[email protected]:~# yum install puppet-server
[email protected]:~# puppet -V
3.7.3
[email protected]:~# facter -v
2.3.0

在客户端安装puppet.

[email protected]:~# yum install puppet

配置puppet

(1)服务端启动.查看监听状态 puppetmaster服务开启后，默认监听TCP 8140端口

[email protected]:manifests# /etc/init.d/puppetmaster start
Starting puppetmaster:                                     [  OK  ]
[email protected]:puppet# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name   
tcp        0      0 0.0.0.0:8140                0.0.0.0:*                   LISTEN      892/ruby 

(2)客户端启动

[email protected]:~# /etc/init.d/puppet start
Starting puppet agent:                                     [  OK  ]

(3)配置主机配置文件.修改site.pp增加输出文件配置.

[email protected]:manifests# cat site.pp 
node default { file { "/tmp/puppettest1.txt": content => "hello,puppet"; } }

(4)客户端发起验证:

[email protected]:~# puppet agent --server puppet.domain.com --test
Info: csr_attributes file loading from /etc/puppet/csr_attributes.yaml
Info: Creating a new SSL certificate request for agent.domain.com
Info: Certificate Request fingerprint (SHA256): B9:15:4E:8B:5F:D3:63:D2:A9:CC:11:74:ED:32:1C:07:EF:61:C5:BF:37:19:26:3A:7D:05:05:3F:4D:23:83:37
Exiting; no certificate found and waitforcert is disabled

如果不使用--server参数指定puppet master服务器,需要在客户端配置文件/etc/puppet/puppet.conf的main指定这一参数,
[main]
server = puppet.domain.com
第二个参数--test使puppet客户端运行时只是测试模式.如果想在前台输出日志到标准输出,可以使用参数--no-daemonize.在默认情况下,puppet客户端是以守护进程的方式运行的.如果想在客户端输出详细的日志,可以使用参数--verbose.--debug参数提供更加详细的输出

(5)服务端完成验证.对agent发送到master的证书进行签名.可以使用puppet cert命令(--list 参数)查看等待被签名的证书.使用sign参数对待被签名的证书进行签名.也可以用--all参数给所有主机签署验证

[email protected]:puppet# puppet cert --list
  "agent.domain.com" (SHA256) B9:15:4E:8B:5F:D3:63:D2:A9:CC:11:74:ED:32:1C:07:EF:61:C5:BF:37:19:26:3A:7D:05:05:3F:4D:23:83:37

[email protected]:puppet# puppet cert sign agent.domain.com
Notice: Signed certificate request for agent.domain.com
Notice: Removing file Puppet::SSL::CertificateRequest agent.domain.com at '/var/lib/puppet/ssl/ca/requests/agent.domain.com.pem'

(6)客户端再次进行配置.因为服务端已经为agent.domain.com主机配置了一个file资源.

[email protected]:puppet# puppet agent --server puppet.domain.com --test
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for agent.domain.com
Info: Applying configuration version '1418226077'
Notice: /Stage[main]/Main/Node[default]/File[/tmp/puppettest1.txt]/ensure: defined content as '{md5}6f009eb2c075367f81dde6ea8fe77e59'
Notice: Finished catalog run in 0.08 seconds

(7)验证配置:

[email protected]:puppet# cat /tmp/puppettest1.txt 
hello,puppet

删除某客户端的认证信息:

puppet  cert --clean {node certname}

[email protected]:certs# puppet cert --clean 10.1.1.35.domain.com
Notice: Revoked certificate with serial 3
Notice: Removing file Puppet::SSL::Certificate 10.1.1.35.domain.com at '/var/lib/puppet/ssl/ca/signed/10.1.1.35.domain.com.pem'
Notice: Removing file Puppet::SSL::Certificate 10.1.1.35.domain.com at '/var/lib/puppet/ssl/certs/10.1.1.35.domain.com.pem'
Notice: Removing file Puppet::SSL::Key 10.1.1.35.domain.com at '/var/lib/puppet/ssl/private_keys/10.1.1.35.domain.com.pem'

同时要在客户端删除ssl目录

rm -rf /var/lib/puppet/ssl/*
