puppet 学习文档
192.168.6.226 为服务端192.168.6.223 为客户端
1,puppet 安装
服务端
关闭selinux iptables
添加hosts
Vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4localhost4.localdomain4 web10
::1 localhost localhost.localdomainlocalhost6 localhost6.localdomain6 web10
127.0.0.1www.test1.com www.aaa.com www.test.com
192.168.6.223 web9.aming.com
192.168.6.226 web10.aming.com
Vim /etc/sysconfig/network
Hostname web10.aming.com
Yum install puppetmaster –y
启动puppetmaster
提示错误需要在hosts里加入主机名
Starting puppetmaster:dnsdomainname: Unknown host
dnsdomainname: Unknown host
ps aux|grep puppet
puppet314183.98.4 142812 42328 ? Ssl 17:07 0:01 /usr/bin/ruby/usr/sbin/puppetmasterd
端口号8140
客户端
Vim /etc/hosts
192.168.6.226 web10.aming.com
192.168.6.223 web9.aming.com
Vim /etc/sysconfig/network
Hostname web9.aming.com
按装puppet
Yum install puppet –y
/etc/init.d/puppet start
在客户端上添加配置
Vim /etc/puppet/puppet.conf
Listen = true
Server = web9.aming.com
runinterval = 30
puppet 应用
注册ca
Puppet agent –test –server web10.aming.com(注册命令)

Puppet cert list –all 查看ca

看到有+号的情况，提示已经加入到服务器的ca列表
如果没有出现+号则使用
puppet cert --sign web10.aming.com
测试
在服务端建立新文件site.pp
vim /etc/puppet/manifests/site.pp
node default {
file {
"/tmp/123.txt": content =>"test,test";
}
}
保存后
在客户端输入
Puppet –test –server web9.aming.com
后再/tmp下出现123.txt

自动认证
客户端
/etc/init.d/puppet stop
Rm –rf /var/lib/puppet/ssl/*
服务端
Puppet cert clean –all
Vim /etc/puppet/puppet.conf
加入一条
Autosign = true
Vim /etc/puppet/autosign.conf
*.aming.com
启动puppetmaster
/etc/init.d/puppetmaster start
启动puppet 客户端
/etc/init.d/puppet start
模块示例
首先编辑在/etc/puppet/modules/创建一个自定义模块testm
在创建cd testm
mkdir -pv {files,manifests,templates}
cd files
echo sdfasfaasfaming.com>aming.txt
vim manifests/init.pp
class testm{
file {"/tmp/aming.txt":
owner => "root",
group => "root",
mode => 0400,
source => "puppet://$puppetserver/modules/testm/aming.txt"
} }
Vim manifests/site.pp
$puppet='web9.aming.com'
node 'web10' {
include testm
}
Web10 为通过查看puppet cert list–all 里的文件得出的
Tail –F /var/log/message

Feb 26 02:03:06 localhostpuppet-agent: Finished catalog run in 0.37 seconds
提示以上内容成功
做目录资源
cd testm/files
vim manifests/init.pp
class testm{
file {"/tmp/aming.txt":
owner => "root",
group => "root",
mode => 0400,
source => "puppet://$puppetserver/modules/testm/aming.txt"
} }
class nginx {
file {"/usr/local/nginx":
owner => "root",
group => "root",
source => "puppet://$puppetserver/modules/testm/nginx",
recurse => true,
purge => true #支持删除操作
}
}
~ Vimmanifests/site.pp
$puppet='web9.aming.com'
node 'web10' {
include testm
include nginx
}

远程执行命令
cd testm/files
vim manifests/init.pp
class nginx {
file {"/usr/local/nginx":
owner => "root",
group => "root",
source => "puppet://$puppetserver/modules/testm/nginx",
recurse => true,
purge => true
}
exec {"123":
unless => "test -f/tmp/aminglinux.txt",
path => ["/bin","/sbin","/usr/bin","/usr/sbin"],
command => "touch /tmp/aminglinux.txt"
}
}
unless => "test -f/tmp/aminglinux.txt" 当文件不存在时可以创建
onlyif => "test -f/tmp/aminglinux.txt" 当问及存在是创建
cron模块
cd testm/files
vim manifests/init.pp
class nginx {
file{"/usr/local/nginx":
owner => "root",
group => "root",
source => "puppet://$puppetserver/modules/testm/nginx",
recurse => true,
purge => true
}
exec {"123":
unless => "test -f /tmp/aminglinux.txt",
path =>["/bin","/sbin","/usr/bin","/usr/sbin"],
command => "touch /tmp/aminglinux.txt"
}
cron{"aming1":
command => "/sbin/ntpdate time.windows.com",
user => "root",
minute => "*/10",
#ensure => "absent" 是否清除命令
}
}
说明：分时日月周分别对应Puppet里面的minute,hour,monthday,month,weekday,ensure设置为absent为删除该任务，如果不设置改行则为建立
