“精神错乱：一遍又一遍地做同样的事情，却期待不同的结果。” - 艾尔伯特爱因斯坦
我有一个 vagrant + chef (w/chef-zero Berkshelf) 构建的盒子，可以运行很多程序，包括 zend-server-php、mongos 和 erlang。我正在使用由 Berkshelf 管理的流行食谱和一个基本的 CentOS 6 盒子（存储在我本地的 Mac 上）。第一次（在 a 之后vagrant destroy）启动此框通常需要多次尝试。上面列出的vagrant up程序之一将失败，我必须vagrant provision一遍又一遍地运行（有时多达 6 次）才能顺利完成整个构建。然而，在极少数情况下，星星会对齐，一切都会在第一次尝试时启动。
我看到的错误通常是明确的超时错误（尽管并非总是如此）。我通常从相当弱的办公室网络连接（<20 Mbps 下降）运行它，这可能解释了为什么在最大下载时会发生故障。
所以这是我的问题：首先，除了网络连接之外，还有其他一些变量可以解释为什么我必须这样做vagrant provision多次使用？如果是这样，我该如何测试和治疗它？其次，有没有办法让 vagrant 继续配置，直到它成功为止？我还没有找到这样做的记录标志/设置，但感觉可能有一个......
谢谢你的帮助。

这是一个 zend-server-php-5.4 失败的例子：
