学习目录 领导说saltstack太慢 机器量一旦上来，saltstack就力不从心，所以要将saltstack转向puppet。
【安装背景】
系统centos 6.5
软件地址:
http://downloads.puppetlabs.com/puppet/
master: 192.168.100.10
agent: 192.168.100.13
因为puppet对ca证书的办法是很对域名了。所以域名一定要解析并且master端最好不要变。
【安装步骤】
时钟同步
ntpdate pool.ntp.org
设置hostname并放入hosts解析
echo "192.168.100.10 master.test.com" >> /etc/hosts echo "192.168.100.13 agent.test.com" >> /etc/hosts
puppet端master和agent端的安装:
puppet是基于ruby的，所以首先要安装ruby语言环境。
yum install ruby -y
安装facter -->收集系统信息的软件命令
################# master 和agent 共同的步骤 #############
tar xvf facter-1.6.13.tar.gz
cd facter-1.6.13
ruby install.rb
## 检查facter安装是否成功
facter 收集系统的信息的命令工具
tar xvf puppet-3.0.0.tar.gz
cd puppet-3.0.0
ruby install.rb
创建puppet 用户否则启动失败
useradd puppet

############## agent 请求证书 master签发证书
agent request agent端向maser端发起证书请求 puppet agent --test --server master.test.com
master accept puppet cert sign agent.test.com 接收指定的 puppet cert sign --all 接收所有的请求
agent fetch
过程1
[root@agent puppet-3.0.0]# puppet agent --test --server master.test.com
Info: Caching certificate for ca
Info: Creating a new SSL certificate request for agent.test.com
Info: Certificate Request fingerprint (SHA256): DB:AC:CB:4E:FC:68:E3:71:B5:45:6E:6C:73:C9:EE:27:11:0F:2D:5A:8F:43:21:53:0D:33:7F:85:87:4B:0E:59
Exiting; no certificate found and waitforcert is disabled
[root@agent puppet-3.0.0]#
过程2:
master端已经有这个请求了 接受就可以了
[root@master puppet]# puppet cert list 或者 puppet cert list --all
"agent.test.com" (SHA256) DB:AC:CB:4E:FC:68:E3:71:B5:45:6E:6C:73:C9:EE:27:11:0F:2D:5A:8F:43:21:53:0D:33:7F:85:87:4B:0E:59
[root@master puppet]#
接收证书:
[root@master puppet]# puppet cert sign agent.test.com
Signed certificate request for agent.test.com
Removing file Puppet::SSL::CertificateRequest agent.test.com at '/var/lib/puppet/ssl/ca/requests/agent.test.com.pem'
过程3:
agent端测试
puppet agent --test --server master.test.com
############### 出错过程 ##########
[root@agent puppet-3.0.0]# puppet agent --test
Error: Could not request certificate: Connection refused - connect(2)
Exiting; failed to retrieve certificate and waitforcert is disabled
我这里的原因是 agent的使用的都是默认配置 没有知道指定master 解决方法:
puppet agent --test --server master.test.com
排除了网络问题的命令: telnet master.test.com 8140
####### 写一个测试用例 测试 master 和 agnet可以通信了 及 master可以管理agent端了 agent可以同步master端了
master端编写一个测试pp
[root@master manifests]# cat site.pp
file { "/tmp/temp1.txt":
content => "Hello World\n"; }
[root@master manifests]# pwd
/etc/puppet/manifests
### agent 进行同步
[root@agent puppet-3.0.0]# puppet agent --test --server master.test.com
Info: Retrieving plugin

[root@agent puppet-3.0.0]# cat /tmp/temp1.txt

上面错误的信息原因:

不影响: 原因未知
【puppet清楚证书】
master端:
