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.txt db01ip=10.10.10.1 puppetip=10.10.0.100 db01sqlip=10.10.10.2 db01user=terry db02ip=10.10.20.2 db02sqlip=10.10.10.4 db02user=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.pp node '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.txt dbip=10.10.10.1 puppet=10.10.0.100 dbsql=10.10.10.2 dbuser=terry 

testdb2 内容

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

结论: 可以在不同主机上匹配不同的 facter 内容
