依赖失败（Puppet）

Question

问题：当我第一次运行puppet配置盒子时，我将遇到依赖性失败错误，并且包含这些错误的文件（apache-solr-dataimporthandler-3.6.1.jar）不会复制到目标目标。但是，第二次进行配置时，不再存在依赖性错误，并且所有文件似乎都被正确复制。

如何在不重新配置的情况下解决依赖性错误？为什么会这样？

清单

file { '/var/lib/tomcat6/webapps/solr.war':
  ensure => present,
  owner   => root,
  group   => root,  
  mode    => 644,   
  source => 'puppet:///modules/solr/apache-solr-3.6.1.war',
  notify => Service['tomcat'],
}

file { '/usr/share/solr':
  ensure => present,
  source => 'puppet:///modules/solr/solr',
  recurse => true,
  require => File['/var/lib/tomcat6/webapps/solr.war'],
  notify => Service['tomcat'],
}

file { '/var/lib/tomcat6/webapps/solr/WEB-INF/web.xml':
  ensure => present,
  owner   => root,
  group   => root,  
  mode    => 644,   
  source => 'puppet:///modules/solr/web.xml',
  require => [ File['/var/lib/tomcat6/webapps/solr.war'], File['/usr/share/solr'] ],
}

file { '/var/lib/tomcat6/webapps/solr/WEB-INF/lib/apache-solr-dataimporthandler-3.6.1.jar':
  ensure => present,
  owner   => root,
  group   => root,  
  mode    => 644,   
  source => 'puppet:///modules/solr/apache-solr-dataimporthandler-3.6.1.jar',
  require => File['/var/lib/tomcat6/webapps/solr.war'],
  notify => Service['tomcat'],
}

目录结构

Answer 1

在我看来，木偶抱怨目录/var/lib/tomcat6/webapps/solr/WEB-INF/lib/在尝试创建/var/lib/tomcat6/webapps/solr/WEB-INF/lib/apache-solr-dataimporthandler-3.6.1.jar时不存在。

我怀疑这个目录是在tomcat检测到新的.war时创建的，但是发生得太晚了，你必须重新启动puppet。

因此，您可能希望通过以下方式明确确保创建此目录：

file
{
    '/var/lib/tomcat6/webapps/solr':
        ensure => directory,
        ;
    '/var/lib/tomcat6/webapps/solr/WEB-INF':
        ensure => directory,
        ;
    '/var/lib/tomcat6/webapps/solr/WEB-INF/lib':
        ensure => directory,
        ;
}

（省略“要求”，因为木偶似乎按照定义的顺序创建它们）

我不是tomcat专家，但您可能希望确保手动创建dirs不会干扰tomcat .war自动检测系统。
