一切按官方文档是最好的哦 虽然英文Oct 27 2021
salt 老是0day问题 ,为了安全 于是上puppet 现在文档真的很少,以前在dovo时,流行得很呢 于是有了本文

aliyun mirrors

* Enable the Puppet platform repository
RH
可以用aliyun mirrors 会更加快 wget -c https://mirrors.aliyun.com/puppet/yum/puppet7/el/7/x86_64/puppet7-release-7.0.0-1.el7.noarch.rpm && rpm -Uvh puppet7-release-7.0.0-1.el7.noarch.rpm
rpm -Uvh https://yum.puppet.com/puppet6-release-el-7.noarch.rpm
debian 10 or kali 2021 只能是 buster 注意
记得要改为google dns 8.8.4.4 or alidns
#wget -c https://apt.puppetlabs.com/puppet6-release-buster.deb && dpkg -i puppet6-release-buster.deb
#on my kali
wget -c https://mirrors.aliyun.com/puppet/apt/puppet7-release-buster.deb && dpkg -i puppet7-release-buster.deb

# 要先配置hosts #On the agent node, run: puppet config set server puppetserver.example.com --section main #3. Connect the agent to the primary server and sign the certificate # on agent node puppet ssl bootstrap You will see a message that looks like: Info: Creating a new RSA SSL key for <agent node> #On the primary server node, sign the certificate: #puppetsrver sudo puppetserver ca sign --certname <name> #我是这个 其实最好不要这个 puppetserver ca sign --all #On the agent node, run the agent again: puppet ssl bootstrap

这里的明天再补上 Sep 26
添加 agent node(全新安装) 和证书配置
add hosts
add hosts on server
#puppet #home 127.0.0.1 puppetserver.example.com 192.168.10.32 puppetserver.example.com 192.168.10.39 puppetagent 192.168.10.33 puppetagent2 192.168.10.38 puppetagent38 192.168.2.200 proxy-intra
add config and hosts on agent
192.168.10.32 puppetserver.example.com cat /etc/puppetlabs/puppet/puppet.conf [main] server = puppetserver.example.com [agent] runinterval=30
添加 agent node(非全新安装) 和证书配置

入门例子
#安装到所有节点 默认是半个小时成效 可以手工执行
cat /etc/puppetlabs/code/environments/production/manifests/site.pp
node default {
package { 'emacs':
ensure => present,
}
}
# 笨方法 两个节点安装 w3m
cat /etc/puppetlabs/code/environments/production/manifests/site.pp
node 'puppetagent' {
package { 'w3m':
ensure => present,
}
}
node 'puppetagent2' {
package { 'w3m':
ensure => present,
}
}
第一个file 例子
#on server
#cat /etc/puppetlabs/code/environments/production/manifests/site.pp
node default {
file { "/tmp/oct28.txt":
content => "hey first puppet file";
}
}
#结果 随便找个 agent node
root@puppetagent:~# cat /tmp/oct28.txt
hey first puppet file
第一个shell 命令例子
cat site.pp
node default {
Exec {path =>"/bin:/sbin:/bin/sh:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin"}
exec { "touch files":
command => "/usr/bin/touch /tmp/mytouch.txt";
}
}
