Linux下安装Puppet

aluminiumfoil 2016-08-03

一、准备环境
1、设置主机名和hosts文件
Master
Linux下安装Puppet
Agent
Linux下安装Puppet
2、启动节点ntpd服务
3、制作本地yum仓库 

4、搭建FTP服务器,提供自定义yum仓库访问接口

[root@master ~]# cat /etc/vsftpd/vsftpd.conf
listen=YES
anonymous_enable=YES
local_enable=YES
write_enable=YES
local_umask=022
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
xferlog_file=/etc/vsftpd/vsftpd.log
xferlog_std_format=YES
ftpd_banner=Welcome to Ftp(installed by DQ)
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

5、将生成好的yum源copy到FTP共享目录中

[root@master ~]# cp -arv /home/puppet /var/ftp/pub/

6、agent上配置远程yum仓库

[root@agent ~]# cat /etc/yum.repos.d/puppet.repo 
[CentOS-puppet]
name=puppetlabs epel gems for centos
baseurl=ftp://master.puppet.com/pub/puppet/
enabled=1
gpgcheck=0
priority=1

测试puppet yum是否可用
Linux下安装Puppet

  • 说明puppet安装依赖ruby-shadow和ruby-augeas,ruby相关的软件包通过EPEL源获取,但是需要设置Master和Agent上EPEL源的优先级比自行制作的puppet低,否则puppet会获取EPEL中高版本安装
  • 可参照步骤3,制作本地yum仓库中的设置,这里不再赘述

二、Master端yum安装配置puppet
1、安装Puppet-server、puppet和facter

[root@master ~]# yum install puppet puppet-server facter -y

Linux下安装Puppet
2、配置puppet.conf 注意:配置文件中有两个certname,[master]中配置的certname是为所有节点认证用的master名称,[agent]中配置的certname是其本身agent的名称,当然不配置默认是和master的名称是一样的。

[root@master ~]# cp /etc/puppet/puppet.conf{,.bak}
[root@master ~]# cat /etc/puppet/puppet.conf |grep "^\s*[^# \t].*$"
[main]
    logdir = /var/log/puppet
    rundir = /var/run/puppet
    ssldir = $vardir/ssl #证书存放目录,默认$vardir为/var/lib/puppet
[agent]
    classfile = $vardir/classes.txt
    server = master.puppet.com #设置agent认证连接master端的服务器名称,注意这个名字必须能够被节点解析
    certname = agent.puppet.com #设置agent端certname名称
    localconfig = $vardir/localconfig
[master]
    certname = master.puppet.com #设置puppetmaster认证服务器名

3、创建site.pp文件 site.pp文件是puppet读取所有模块pp文件的开始,在3.0版本以前必须设置,否则服务无法启动。

[root@master ~]# touch /etc/puppet/manifests/site.pp

4、启动puppetmaster服务

[root@master ~]# /etc/init.d/puppetmaster start
Starting puppetmaster:                                     [  OK  ]

5、查看本地证书情况 puppetmaster第一次启动会自动生成证书自动注册自己

[root@master ~]#  tree /var/lib/puppet/ssl/
/var/lib/puppet/ssl/
├── ca
│   ├── ca_crl.pem
│   ├── ca_crt.pem
│   ├── ca_key.pem
│   ├── ca_pub.pem
│   ├── inventory.txt
│   ├── private
│   │   └── ca.pass
│   ├── requests
│   ├── serial
│   └── signed
│       └── master.puppet.com.pem  #已注册
├── certificate_requests
├── certs
│   ├── ca.pem
│   └── master.puppet.com.pem
├── crl.pem
├── private
├── private_keys
│   └── master.puppet.com.pem
└── public_keys
    └── master.puppet.com.pem

9 directories, 13 files
[root@master ~]# puppet cert --list --all
+ "master.puppet.com" #带+标示已经注册成功(CF:74:C7:C7:91:DB:F5:82:3A:5E:01:93:E8:23:64:C4) 
+ (alt names: "DNS:master.puppet.com", "DNS:puppet", "DNS:puppet.puppet.com")

6、查看监听状态 puppetmaster服务开启后,默认监听TCP 8140端口
Linux下安装Puppet
二、Agent端yum安装配置puppet
1、安装puppet和facter

[root@agent ~]# yum install puppet facter -y

Linux下安装Puppet
2、配置puppet.conf
Linux下安装Puppet
3、agent通过调试模式启动节点向master端发起认证
Linux下安装Puppet
4、master端确定认证

[root@master ~]# puppet cert --list --all
[root@master ~]# puppet cert --sign agent.puppet.com
[root@master ~]# tree /var/lib/puppet/ssl/

查看认证情况,agent未认证
Linux下安装Puppet
注册agent
Linux下安装Puppet
再次查看认证情况,agent已认证
