puppet 类、模块
为了通用目标或目的组织在一起的一个或多个资源叫类
[root@puppet manifests]# cat test.pp
class nginx { #定义类名
package {'nginx': #定义资源
ensure => present,
}
service {'nginx':
ensure => true,
require => Package['nginx'],
}
}
include nginx #声明类
#class {'nginx'} #这种方式也可以声明类
执行
puppet apply test.pp -v -d
一个带传参的类
[root@puppet manifests]# cat test1.pp
$webserver = $operatingsystem ? {
/^(?i-mx:redhat|centos|fedora)/ => 'httpd',
/^(?i-mx:ubuntu|debian)/ => 'apache2',
}
class httpd ($pkgname='apache2') {
package {"$pkgname":
ensure=>present,
}
service {"$pkgname":
ensure=>true,
require=>Package["$pkgname"],
}
}
class {'httpd':
pkgname => $webserver ,
}
执行
puppet apply test1.pp -v -d
类的继承
[root@puppet manifests]# cat test2.pp
class nginx {
package {"nginx":
ensure=>present,
}
}
class nginx::rproxy inherits nginx {
file {'/etc/nginx/nginx.conf':
ensure=>file,
source=>'/tmp/nginx/nginx.rproxy.conf',
notify=>Service['nginx'],
}
service {'nginx':
ensure=>true,
}
}
class nginx::web inherits nginx {
file {'/ect/nginx/nginx.conf':
ensure=>file,
source=>'/tmp/nginx/nginx.web.conf',
notify=>Service['nginx'],
}
service {'nginx':
ensure=>true,
}
}
class {'nginx::rproxy'}
或者导入
[root@puppet manifests]# cat node.pp
import "/etc/puppet/manifests/test2.pp"
include nginx::rproxy
执行
puppet apply node.pp -v -d
模块
[root@puppet puppet]# cd modules/ #创建nginx模块
[root@puppet modules]# ls
nginx
[root@puppet modules]# mkdir -pv nginx/{manifests,files,templates,lib} #必须包含的文件夹
[root@puppet nginx]# cd manifests/
[root@puppet manifests]# ls
init.pp nginx.rproxy.pp nginx.web.pp #init.pp 必须包含的文件 声明类
[root@puppet manifests]# cat init.pp nginx.rproxy.pp nginx.web.pp #查看3个文件内容 都是刚才定义的类
class nginx {
package {"nginx":
ensure=>file,
}
}
class nginx::rproxy inherits nginx {
file {'/etc/nginx/nginx.conf':
ensure=>file,
source=>'puppet:///modules/nginx/nginx.rproxy.conf', #这个路径不需要files目录 会自动找
notify=>Service['nginx'],
}
service {'nginx':
ensure=>true,
}
}
class nginx::web inherits nginx {
file {'/ect/nginx/nginx.conf':
ensure=>file,
source=>'puppet:///modules/nginx/nginx.web.conf',
notify=>Service['nginx'],
}
service {'nginx':
ensure=>true,
}
}
[root@puppet files]# cp /tmp/nginx/nginx.* . #copy 文件到files 依赖或者额外的配置文件都要放到files
[root@puppet files]# ls
nginx.rproxy.conf nginx.web.conf
单独
[root@puppet manifests]# cat init.pp
class nginx {
package {"nginx":
ensure=>present,
}
file {'/etc/nginx/nginx.conf':
ensure=>file,
source=>'puppet:///modules/nginx/nginx.web.conf',
}
service {'nginx':
ensure=>true,
}
}
测试
[root@puppet manifests]# puppet apply -e 'include nginx' -v -d
一个网络模型下的模块
class jdk{ #声明类名 将相应的rpm包文件 放到模块路径下的files目录里
file {'/opt/jdk-8u45-linux-x64.rpm':
source=>'puppet:///modules/jdk/jdk-8u45-linux-x64.rpm',
group=>'root',
owner=>'root',
}
file{'/etc/profile.d/java.sh':
# ensure=>present,
source=>'puppet:///modules/jdk/java.sh',
group=>'root',
owner=>'root',
}
exec {'install':
cwd=>'/opt',
path=>'/usr/local/bin:/usr/bin:/bin:',
command=>'rpm -ivh jdk-8u45-linux-x64.rpm',
creates=>'/usr/java/jdk1.8.0_45/bin/java',
subscribe=>File['/opt/jdk-8u45-linux-x64.rpm'],
require=>File['/opt/jdk-8u45-linux-x64.rpm'],
}
exec {'sh':
cwd=>'/etc/profile.d/',
creates=>'/etc/profile.d/java.sh',
path=>'/usr/local/bin:/usr/bin:/bin',
command=>'sh java.sh',
require=>File['/etc/profile.d/java.sh'],
}
}
然后在site.pp里面声明
node 'agent.cc.com'{
include jdk
}
