Puppet集中管理系统配置

loiv

一、什么是puppet？
1、基于ruby语言开发的系统配置集中管理工具，跨平台
2、一个C/S架构，配置服务端和客户端
puppet依赖于ruby与facter，安装puppet3.x，需要ruby1.8.7版本及以上；facter是一个系统盘点工具，收集主机的一些资料，比如CPU，主机IP等
3、puppet是一个C/S结构，开源软件，基于Ruby的系统配置管理工具，安装puppet3.x，需要ruby1.8.7版本及以上
4、默认情况下，客户端每隔30分钟连接一次puppet服务端
二、环境介绍
1、拓扑图

2、下载
操作系统RHEL6.3 x64
facter下载: https://downloads.puppetlabs.com/facter/
puppet下载: https://downloads.puppetlabs.com/puppet/
3、puppetpuppetmaster与puppetclient可以相互解析
vi /etc/hosts
192.168.0.200 puppetpuppetmaster.com
192.168.0.201 puppetclient1.com
4、puppet服务端与客户端时间同步
yum install ntp -y
service ntpd start
ntpdate pool.ntp.org #同步时间
clock -w #将时间写入硬件
chkconfig ntpd on
三、安装服务端puppet
1、安装ruby环境

[iyunv@puppetmaster ~]# yum install -y ruby ruby-libs ruby-shadow
2、安装facter



[iyunv@puppetmaster ~]# tar zxvf facter-1.7.3.tar.gz
[iyunv@puppetclient1 ~]# cd facter-1.7.3
[iyunv@puppetmaster facter-1.7.3]# ruby install.rb
3、安装配置puppet


[iyunv@puppetmaster puppet-3.3.1]# useradd -s /sbin/nologin puppet
[iyunv@puppetmaster ~]# tar zxvf puppet-3.3.1.tar.gz
[iyunv@puppetclient1 ~]# cd puppet-3.3.1
[iyunv@puppetclient1 puppet-3.3.1]# ruby install.rb
[iyunv@puppetmaster puppet-3.3.1]# cp ext/redhat/puppet.conf /etc/puppet/
[iyunv@puppetmaster puppet-3.3.1]# cp ext/redhat/server.init /etc/init.d/puppetmaster
[iyunv@puppetmaster puppet-3.3.1]# chmod +x /etc/init.d/puppetmaster
[iyunv@puppetmaster puppet-3.3.1]# chkconfig --add puppetmaster
[iyunv@puppetmaster puppet-3.3.1]# chkconfig puppetmaster on
[iyunv@puppetmaster puppet-3.3.1]# service puppetmaster start


[iyunv@puppetmaster ~]# vi /etc/puppet/puppet.conf
[main]  #在main里面添加puppet服务端主机名
server = puppetmaster.com
四、安装客户端puppet Agent
1、安装ruby环境

[iyunv@puppetclient1 ~]# yum install -y ruby ruby-libs ruby-shadow
2、安装facter


[iyunv@puppetclient1 ~]# tar zxvf facter-1.7.3.tar.gz
[iyunv@puppetclient1 ~]# cd facter-1.7.3
[iyunv@puppetclient1 facter-1.7.3]# ruby install.rb
3、安装配置puppet


[iyunv@puppetclient1 puppet-3.3.1]# useradd -s /sbin/nologin puppet
[iyunv@puppetclient1 ~]# tar zxvf puppet-3.3.1.tar.gz
[iyunv@puppetclient1 puppet-3.3.1]# ruby install.rb
[iyunv@puppetclient1 puppet-3.3.1]# cp ext/redhat/puppet.conf /etc/puppet/puppet.conf
[iyunv@puppetclient1 puppet-3.3.1]# cp ext/redhat/client.init /etc/init.d/puppet
[iyunv@puppetclient1 puppet-3.3.1]# chmod +x /etc/init.d/puppet
[iyunv@puppetclient1 puppet-3.3.1]# chkconfig --add puppet
[iyunv@puppetclient1 puppet-3.3.1]# chkconfig puppet on
[iyunv@puppetclient1 puppet-3.3.1]# service puppet start


[iyunv@puppetclient1 ~]# vi /etc/puppet/puppet.conf
[main]  #在main里面添加puppet服务端主机名
server = puppetmaster.com
五、配置签名证书
1、客户端创建证书注册请求


[iyunv@puppetclient1 ~]# puppet agent --test
Info: Creating a new SSL key for puppetclient1.com
Info: Caching certificate for ca
Info: Creating a new SSL certificate request for puppetclient1.com
Info: Certificate Request fingerprint (SHA256): 7E:10:48:3F:3C:D4:13:BA:BF:66:ED:86:52:92:19:05:1E:D2:3A:CD:06:67:27:80:60:D6:54:66:0E:33:F7:C7
Exiting; no certificate found and waitforcert is disabled
2、服务端查看证书注册请求


[iyunv@puppetmaster ~]# puppet cert list  #加--all查看所有
  "puppetclient1.com"     (SHA256) 7E:10:48:3F:3C:D4:13:BA:BF:66:ED:86:52:92:19:05:1E:D2:3A:CD:06:67:27:80:60:D6:54:66:0E:33:F7:C7
  "puppetclient1.com.com" (SHA256) 46:B6:95:A6:1B:6A:FD:83:E4:1C:72:D4:5C:3C:B5:EF:3D:F7:43:2C:09:CF:00:B8:44:18:E4:3E:B3:DC:6F:FD
3、服务端受理客户端证书注册请求


[iyunv@puppetmaster ~]# puppet cert sign puppetclient1.com  #主机名改为--all，是受理所有
Notice: Signed certificate request for puppetclient1.com
Notice: Removing file Puppet::SSL::CertificateRequest puppetclient1.com at '/var/lib/puppet/ssl/ca/requests/puppetclient1.com.pem'
4、客户端确认是否证书注册成功


[iyunv@puppetclient1 ~]# puppet agent --test
如果出现以下报错，则在客户端puppet.conf配置文件[main]里面添加pluginsync=false，再重启！

Error: /File[/var/lib/puppet/lib]: Could not evaluate: Could not retrieve information from environment production source(s) puppet://puppetmaster.com/plugins
5、服务端清除证书

[iyunv@puppetmaster ~]# puppet cert clean puppetclient1.com
六、简单测试
1、服务端编写配置


[iyunv@puppetmaster ~]# vi /etc/puppet/manifests/site.pp #修改后立即，无需重启
file { "/tmp/test.txt":
        content=> "hello,puppet test";
}
2、客户端默认30分钟与服务端同步配置文件，所以我们手动执行，也可以修改puppet.conf更改默认时间，添加runinterval=600，设置为10分钟同步一次


[iyunv@puppetclient1 ~]# puppet agent --test
[iyunv@puppetclient1 ~]# ls /tmp/
test.txt

至此，基本的puppet系统配置完成！
