如何使用puppet在服務器上設置環境變量？

Question

我開始在當前項目中使用puppet，並且遇到一些問題。

我正在使用一個配方來安裝jruby，但是我想在它完成安裝jruby之後設置一個環境變量（在這種情況下，JRUBY_HOME並修改PATH以包含JRUBY_HOME/bin）。

這裏的食譜：

class jruby { 
    $jruby_home = "/opt/jruby" 


    exec { "download_jruby": 
    command => "wget http://jruby.org.s3.amazonaws.com/downloads/1.7.0.RC2/jruby-bin-1.7.0.RC2.tar.gz", 
    path => $path,  
    timeout => 0, 
    unless => "ls /opt | grep jruby-1.7.0", 
    require => Package["openjdk-7-jre-headless"] 
    }     

    exec { "unpack_jruby" : 
    command => "tar -zxf jruby-bin-1.7.0.RC2.tar.gz -C /opt", 
    path => $path, 
    creates => "${jruby_home}-1.7.0.RC2", 
    require => Exec["download_jruby"] 
    }        

    file { $jruby_home: 
    ensure => link, 
    target => "${jruby_home}-1.7.0.RC2", 
    require => Exec["unpack_jruby"] 
    }       

} 

那麼，有什麼補充的最佳途徑的/ opt/JRuby的作爲JRUBY_HOME然後添加JRUBY_HOME/bin添加到路徑？

解決它：

# init.pp 
$jruby_sh = "/etc/profile.d/jruby.sh" 
file { $jruby_sh: 
    ensure => present, 
    source => "puppet:///modules/jruby/jruby.sh", 
    owner => "root", 
    group => "root", 
    mode => 644, 
    require => File[$jruby_home] 
} 

# jruby.sh 
export JRUBY_HOME=/opt/jruby 
export PATH=$PATH:$JRUBY_HOME/bin
