tips：检查puppet版本：

puppet --version

我安装的版本是3.7.4

最近因为安装了saltstack，不知道为什么salt执行命令很慢（CPU使用率高），又暂时找不到什么解决方案（怀疑是bug），于是滚回puppet的世界

参考了这篇资料，安装了puppet：https://docs.puppetlabs.com/guides/install_puppet/install_debian_ubuntu.html

分别在master和agent上安装了puppetmaster和puppet（agent），但是默认的agent是不启用的，

so，编辑：/etc/default/puppet文件，把当中的START=no改为yes：

# Defaults for puppet - sourced by /etc/init.d/puppet
# Enable puppet agent service?
# Setting this to "yes" allows the puppet agent service to run.
# Setting this to "no" keeps the puppet agent service from running.
START=yes
# Startup options
DAEMON_OPTS=""

再执行：service puppet start即可

后来在agent或master上执行命令时都弹出以下警告：

root@workgroup1:~# puppet agent --server workgroup0.hzg.com --test

警告内容如下：

Warning: Setting templatedir is deprecated. See http://links.puppetlabs.com/env-settings-deprecations(at /usr/lib/ruby/vendor_ruby/puppet/settings.rb:1139:in `issue_deprecation_warning')

参考这里：https://tickets.puppetlabs.com/browse/PUP-2566

把/etc/puppet/puppet.conf文件中的：

# templatedir=$confdir/templates

注释掉即可。
