Puppet安装与配置-自学
环境:CoentOS 5.8 x86_64 ,selinux,iptables 已经关闭puppetmaster 192.168.1.90 puppetmaster.info.com
client 192.168.1.223 client.info.com
原理图：
1) 客户端通过facter收集客户端信息并发送至服务端
2) 连接服务端并请求catalog日志
3) 请求节点（node）的信息
4) 从服务器端接收节点（node)的实例
5) 编译代码（包括语法检查等工作）
6) 查询是否有exported 虚拟资源
7) 如有，则从数据库接收虚拟资源
8) 接收完整的catalog日志
9) 存储catalog日志到数据库
10) 客户端接收完整的catalog日志

连接测试
# telnet puppetmaster.info.com8140
Trying192.168.1.90...
Connected topuppetmaster.info.com.
Escape character is'^]'.
Connection closedby foreign host.
# puppetd --test --server puppetmaster.info.com
命令是指puppetd 从 puppetmaster.info.com去读取puppet配置文件。第一次连接，双方会进行ssl证书的验证，这是一个新的客户端，在服务器端那里还没有被认证，因此需要在服务器端进行证书认证。
客户端查看批准证书
# puppetca –l 查看待批准的证书
"client.info.com"(3E:6D:13:F9:29:FB:6F:DB:76:95:80:5C:E2:3D:68:76)
# puppetca -s client.info.com 批准当前证书
notice: Signedcertificate request for client.info.com
notice:RemovingfilePuppet::SSL::CertificateRequestclient.info.comat'/var/lib/puppet/ssl/ca/requests/client.info.com.pem'
# puppetca -a --list 查看已批准的证书
+"client.info.com" (37:3A:82:F6:72:9B:1A:4D:01:66:F9:AB:CA:A6:FB:4E)
#puppetca -s –a 批准全部证书
服务器端的/etc/puppet/puppet.conf加入这行：
autosign = true服务端就自动签证书
如果想重新签证书，需要把/var/lib/puppet/ssl/下清空
#puppetd --test -serverpuppetmaster.info.com 从服务器取回已批准的证书
# pwd
/var/lib/puppet/ssl/certs 客户端证书路径
# ls
ca.pemclient.info.com.pem
验证证书是否正确
# md5sum client.info.com.pem
eb31668083c03a31d700663e4acf018bclient.info.com.pem
# md5sumclient.info.com.pem
eb31668083c03a31d700663e4acf018bclient.info.com.pem
功能测试
# vim /etc/puppet/manifests/site.pp
node default {
file{"/tmp/viong.txt":
content=>"good,testpass!\nHello World!\n";}
}
# servicepuppetmaster restart
停止 puppetmaster： [失败]
启动 puppetmaster： [确定]
上面的代码对默认连入的puppet客户端执行一个操作,在/tmp目录生成一个viong.txt文件,内容是good,test pass! 回车换行Hello World!回车换行.
客户端查看
# puppetd --test --server puppetmaster.info.com
