我不知道这是一个错误还是某种滥用/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，主要是以下几种

  • 在节点上找不到类

  • 在节点上找不到定义类

当 puppet 模块/清单更改时会发生这些错误 - 但它只发生一次。如果发生这种情况，受影响的 puppet 代理将使用他们的缓存目录一次。下次这些代理请求目录时，它会完美编译，一切都会像魅力一样工作——所有错误都消失了。问题是我们有大型目录的代理。他们的目录运行可能需要超过一分钟，因此应用更改所需的时间将加倍，最多需要 2 甚至 3 分钟。

通常模块/清单的更改由“git pull”执行。但是通过简单的“触摸”操作很容易重现这些错误信息。这里有一些有趣的日志观察和它们的[共性]。是的 AFAICS 他们总是以三胞胎出现。很少发生修改后根本没有这样的问题。

切换到 Apache/Passenger/Rack 解决方案（并转储 WEBrick）似乎可以解决这个问题。附加信息：http ://projects.puppetlabs.com/issues/19642

当我重命名 Puppet 模块/类时发生了这种情况，这导致：

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上为 Passenger 服务了 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

此外，如果您使用代码版本控制系统（应该是 :)），如 git 或 svn，请确保您确实将更新推送到 puppet master。换句话说，检查您的模块是否确实存在于 Puppet 正在寻找它的位置，例如/etc/puppet/modules/foo. 我已经为此绊倒了几次。

就我而言，这是 puppet master 的语言环境问题（我的一些清单包含本地化注释），因此 Puppet 3.8 默默地无法编译它们。

检查locale控制台中的命令输出（不应抱怨任何事情）。

sudo dpkg-reconfigure locales我通过运行并插入下一行来修复它/etc/default/locale：

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

此外，我使用 apache2 和乘客来运行 Puppet master，所以我还需要替换下一个字符串/etc/init.d/apache2：

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

到：

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 要求所有文件都采用 ASCII 编码。
