工头与木偶节点.rb错误404未找到

Question

我已经安装了foreman-1.2和puppet，安装后我已经在foreman上注册了我的puppet到smart-proxy。

当我运行以下命令

时

[root@puppet ~]# puppet agent -t
Warning: Unable to fetch my node definition, but the agent run will continue:
Warning: Error 400 on SERVER: Failed to find puppet.example.com via exec: Execution of '/etc/puppet/node.rb puppet.example.com' returned 1: --- false
Info: Retrieving plugin
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed when searching for node puppet.example.com: Failed to find puppet.example.com via exec: Execution of '/etc/puppet/node.rb puppet.example.com' returned 1: --- false
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

I tried following

[root@puppet ~]# /etc/puppet/node.rb puppet.example.com
--- false
Error retrieving node puppet.example.com: Net::HTTPNotFound

foreman.log调试

我错过了什么吗?我需要先在foreman GUI上创建主机吗?我不理解node.rb的概念

Answer 1

首先应该检查node.rb的内容。要使其工作，需要设置许多变量。看起来这还没有完成，因为"Net::HTTPNotFound"说它找不到你的Foreman服务器。

第二，是和不是——主机需要首先在froman中定义。如果主机在Foreman中还不存在，那么Foreman"可能"会创建它——这实际上取决于你是如何设置Foreman的。

如果内存正常，我相信当节点上传事实时，会创建一个不存在的主机。Rb(如果启用了)。如果您只是从命令行运行它，那么没有上载事实，也没有创建主机。

对于您的测试，确保在Foreman中创建主机。然后测试节点。

编辑:你的最后一个问题:节点。Rb的主要功能是获取服务器的yaml格式配置并将其交给puppet。其次，它还可以将事实从服务器上传到Foreman——这可以用于在Foreman中对服务器进行分类。

Answer 2

基本上，您必须确保主服务器和代理服务器彼此熟悉(通过/etc/hosts或dns)。当主机无法解析代理的名称(例如puppet.example.com)
