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

* 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

* 4. Install PuppetDB (optional)

configure

https://puppet.com/docs/puppet/7/install_agents.html#agent_primary_server_connections


# 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

#注意  一般server 接受了证书后 还要过几分钟才完成 最终提示如下

接受证书 on server

#certname 看生成证书时的提醒 一般是你的node agent的hostname

#执行完成 提示如下

添加 agent node(非全新安装) 和证书配置

官方文档最6 https://puppet.com/docs/puppet/7/ssl_regenerate_certificates.html

puppetserver ca   list  --all
Signed Certificates:

#先删除原来存在的了key  on server   这几步 也是 puppet rror: The certificate for 'CN=' does not match its private key的解决办法 
puppetserver ca clean --certname  idc-test-all-db-192-168-10-120-c7 
puppetserver ca clean --certname idc-test-all-php-192-168-10-122-c7


#如果有老的key 不是新安装 
cd  /etc/puppetlabs/puppet/ssl/certs/

#这个是接受后成功的提示 ,如果只有这个提示 没有前面的 那就是在servrer 存在了相同的了 
Notice: Completed SSL initialization



#sever 上接受 成功喽 
#单独一个  
puppetserver ca sign --certname  puppet2021

puppetserver ca sign   --all
Successfully signed certificate request for idc-test-all-php-192-168-10-122-c7



#这个命令还是不成功 
puppetserver ca sign  idc-test-all-php-192-168-10-122-c7


例如
#最后在master 接受的证书名是以hostname的哦  最好是事先起好hostname,虽然我hosts文件配置为puppet38 配置任务用这个也是成功的 ,不过还是不够规范
 puppetserver ca sign   --all
Successfully signed certificate request for debian11


默认30分钟太久

#on agent  120 秒  ,2 分钟 
vi  /etc/puppetlabs/puppet/puppet.conf 
[agent]
server = master.test.cn
runinterval=120

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";
  }
}



第一个 配置一个测试节点 modules


cd /etc/puppetlabs/code/environments/production/modules
root@master:/etc/puppetlabs/code/environments/production/modules# 
mkdir -p  test/{manifests,templates,files}


vi templates/test.erb 
hostname <%= fqdn %>

vi  manifests/init.pp
class  test {
    file {"/tmp/$hostname.txt": content => "hey world";}
}


root@master:/etc/puppetlabs/code/environments/production/manifests# mkdir nodes

vi agent1.pu.com.pp
node 'agent1.pu.com' {
   include test
}


主动拉取
root@agent1:~# puppet agent -t 




 cat   ../site.pp
node default {
    package { 'tree':
     ensure => present,
  }
}

#其实只要这行 上面和下面的全可不要 
import "nodes/agent1.pu.pp"
#include的写法  但是好像有问题  这个所有的 
import  "nodes/*.pp"



成功  暂时是只有  agent1 有,因为开始只是node 里只有 agent1  
root@agent1:~# cat /tmp/agent1.txt 
hey world
