puppet 利用 facter, 实现不同主机调用不同变量方法

来源：互联网发布：英文单词翻译软件编辑：程序博客网时间：2024/06/06 05:28

分析¶

变量类型常见三种

1. 内建变量, 如 $title, $name 等, 针对类固定的格式而进行调用2. 自定义变量, 如 myname = tttttt, 等, 但需要在每个类中进行独立定义, 不能够在类之间进行传递, 3. facter , 公共变量, 可以在每个类中共同使用, 当前打算使用 facter 作为变量的调用

测试1.¶

修改 /etc/puppet/fileserver.conf 如下, 目的, 创建文件传输目录

grep -v "#" /etc/puppet/fileserver.conf  | grep -v ^$[extra_files]  path /etc/puppet/files  allow *

创建对应目录

mkdir /etc/puppet/files

把 facter 模板存放至 /etc/puppet/files

cat /etc/puppet/files/roles.txtdb01ip=10.10.10.1puppetip=10.10.0.100db01sqlip=10.10.10.2db01user=terrydb02ip=10.10.20.2db02sqlip=10.10.10.4db02user=bbxxswqq

创建测试用 puppet 推送模板

[root@gd02-openstack-puppet manifests]# tree.├── openstack│   ├── cinder.vclound.com.pp│   ├── db.vclound.com.pp│   ├── galera.vclound.com.pp│   ├── glance.vclound.com.pp│   ├── glusterfs.vclound.com.pp│   ├── haproxy.vclound.com.pp│   ├── keystone.vclound.com.pp│   └── test.pp                  <--- 测试用模板└── site.pp

测试模板内容

[root@gd02-openstack-puppet manifests]# cat openstack/test.ppnode 'gd02-openstack-testdb1.vclound.com', 'gd02-openstack-testdb2.vclound.com' {  file { [ '/etc/facter','/etc/facter/facts.d']:      ensure => directory,      owner => root, group => root,      mode => 0755,  }  file { '/etc/facter/facts.d/roles.txt':      source =>  "puppet://$fileserver/extra_files/roles.txt",      owner => root, group => root,      mode => 0755,      require => File [ '/etc/facter','/etc/facter/facts.d'],  }  if $fqdn == "gd02-openstack-testdb1.vclound.com"   {        file { "/tmp/test.txt":                content => "dbip=$db01ip\npuppet=puppetip\ndbsql=$db01sqlip\ndbuser=$db01user\n",                owner => root, group => root,                mode => 644,                require => File ['/etc/facter/facts.d/roles.txt'],        }  }elsif $fqdn == "gd02-openstack-testdb2.vclound.com"   {        file { "/tmp/test.txt":                content => "dbip=$db02ip\npuppet=$puppetip\ndbsql=$db02sqlip\ndbuser=$db02user\n",                owner => root, group => root,                mode => 644,               require => File ['/etc/facter/facts.d/roles.txt'],        }  }}

目的, 分别在 'gd02-openstack-testdb1.vclound.com', 'gd02-openstack-testdb2.vclound.com' 主机中添加 /tmp/test.txt
文件中分别调用 facter 变量
效果如下

testdb1 内容

[root@gd01-openstack-testdb1 ~]# cat /tmp/test.txtdbip=10.10.10.1puppet=10.10.0.100dbsql=10.10.10.2dbuser=terry

testdb2 内容

[root@gd02-openstack-testdb2 /]# cat /tmp/test.txtdbip=10.10.20.2puppet=10.10.0.100dbsql=10.10.10.4dbuser=bbxxswqq

结论: 可以在不同主机上匹配不同的 facter 内容
