Ubuntu 16.04搭建puppet服务：
Puppet是一种配置管理工具，可帮助系统管理员自动执行服务器基础架构的配置和管理。
一、安装软件
master：
curl -O https://apt.puppetlabs.com/puppetlabs-release-pc1-xenial.deb
dpkg -i puppetlabs-release-pc1-xenial.deb
apt-get update
apt-get install puppetserver
ln -s /opt/puppetlabs/bin/puppet /usr/bin/
systemctl start puppetserver
systemctl enable puppetserver
agent:
curl -O https://apt.puppetlabs.com/puppetlabs-release-pc1-xenial.deb
dpkg -i puppetlabs-release-pc1-xenial.deb
apt-get update
apt-get install puppet-agent
ln -s /opt/puppetlabs/bin/puppet /usr/bin/
systemctl start puppet
systemctl enable puppet
二、证书签名
agent:
vi /etc/hosts
10.0.0.2 puppet （puppet master服务器）
:wq
puppet agent -t
master:
puppet cert list
puppet cert sign puppeta.ming.com （根据上1步的显示）
1次性部署所有请求：
puppet cert sign --all
三、推送验证
master:
vi /etc/puppetlabs/code/environments/production/manifests/site.pp
file {'/tmp/it_works.txt':
ensure => present,
mode => '0644',
content => "It works on ${ipaddress_eth0}!\n",
}
:wq
agent:
