Puppet：在清单/模块更改后经常*“找不到类”打嗝*

标签： class module manifest puppet

我不知道这是一个错误还是某种误用/错误配置。希望有人可以提供帮助。谢谢！

如果我更改模块或清单目录中的文件，这通常会导致错误，主要是以下类型

  • 无法在节点

    • 上找到课程

  • 在节点

    • 上找不到定义类

当木偶模块/清单发生变化时会发生这些错误 - 但只发生一次。如果它发生，受影响的木偶代理将使用他们的缓存目录一次。 下次这些代理商请求目录时，它会被完美地编译，一切都会像魅力一样 - 所有错误都消失了。问题是我们有代理商有大型目录。他们的目录运行时间可能超过一分钟，因此应用更改所需的时间将翻倍，最多需要2分钟甚至3分钟。

模块/清单的更改通常由“git pull”执行。但是通过简单的“触摸”操作很容易重现这些错误消息。以下是一些有趣的日志观察及其[共性]。是的AFAICS他们总是出现在三胞胎中。修改后很少发生这样的问题。

受影响的类和节点似乎是随机选择的。

切换到Apache / Passenger / Rack解决方案（并转储WEBrick）似乎解决了这个问题。 其他信息：http://projects.puppetlabs.com/issues/19642

答案 1 :(得分：1)

当我重命名Puppet模块/类时，我发生了这种情况，结果是：

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class foo for example on node myhost.example.com
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

我在Apache + Foreman上使用Passenger服务Puppet，所以我找到的解决方案是重新启动httpd和foreman-proxy：

sudo service httpd restart
sudo service foreman-proxy restart

另外，如果您使用代码版本控制系统（如您所愿:) :)，例如git或svn，请确保您实际将更新推送到puppet master。换句话说，检查您的模块是否确实存在于Puppet寻找的位置，例如： /etc/puppet/modules/foo。我几次绊倒了自己。

答案 2 :(得分：0)

在我的情况下，这是puppet master上的语言环境问题（我的一些清单包含本地化的注释），所以Puppet 3.8无法编译它们。

检查控制台中locale命令的输出（不应该抱怨任何事情）。

我通过运行sudo dpkg-reconfigure locales并将下一行插入/etc/default/locale来修复它：

LC_ALL="ru_RU.UTF-8"
LANG="ru_RU.UTF-8"
LANGUAGE="ru_RU:ru:en"

此外，我正在使用apache2与乘客一起运行Puppet master，所以我还需要替换/etc/init.d/apache2中的下一个字符串：

ENV="env -i LANG=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

为：

ENV="env -i LANG=ru_RU.UTF-8 LC_ALL=ru_RU.UTF-8 PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

事实证明，在C语言环境下启动的Ruby会使所有文件都采用ASCII编码。
