up:清单/模块更改后“经常”一次“经常找不到班级”打h

[英]Puppet: “Could not find class” hiccups *often* once after manifest/module changes

我不知道这是一个错误还是某种滥用/配置错误。 希望有人能帮忙。 谢谢!

如果我更改模块或清单目录中的文件,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

当更改人偶模块/清单时会发生这些错误-但仅发生一次。 如果发生这种情况,受影响的人偶代理将使用其缓存的目录一次。 下次这些代理请求目录时,它将完美无缺地进行编译,并且所有内容都将像魅力一样工作 –所有错误都消失了。 问题是我们的代理商目录很大。 他们的目录运行可能需要一分钟以上的时间,因此应用更改所花费的时间将加倍,最多需要2分钟甚至3分钟。

通常,模块/清单的更改是通过“ git pull”执行的。 但是通过简单的“触摸”操作很容易重现这些错误消息。 这是一些有趣的日志观察及其[共性]。 是的,它们总是出现在三胞胎中。 修改后很少有根本没有这样的问题。

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)似乎可以解决此问题。 附加信息: http//projects.puppetlabs.com/issues/19642

我重命名了Puppet模块/类时发生了这种情况,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

我让Puppet在Apache + Foreman上与Passenger一起使用,所以我发现的解决方案是让httpd和foreman-proxy重新启动:

sudo service httpd restart
sudo service foreman-proxy restart

另外,如果您使用的是git或svn之类的代码版本控制系统(应该是:)),请确保确实将更新推送到了puppet master。 换句话说,检查您的模块是否确实存在于Puppet所寻找的位置,例如/etc/puppet/modules/foo 我已经绊了几次。

在我的情况下,这是puppet master上的语言环境问题(我的某些清单包含本地化注释),因此Puppet 3.8静默无法编译它们。

在控制台中检查locale命令的输出(不应抱怨任何内容)。

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"

另外我正在将apache2与乘客一起使用来运行Puppet master,因此我还需要从以下位置替换/etc/init.d/apache2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"

至:

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认为所有文件都采用ASCII编码。
