“疯狂：一遍又一遍地做同样的事情，期待着 不同的结果。“ - 阿尔伯特爱因斯坦
我有一个流浪汉+厨师（w / chef-zero Berkshelf）内置框，可以运行很多程序，包括zend-server-php，mongos和erlang。我正在使用流行的食谱，用Berkshelf管理，以及一个基本的CentOS 6盒子（存储在我的本地Mac上）。第一次启动此框（在vagrant destroy之后）通常需要多次尝试。 vagrant up将在上面列出的某个程序上失败，我将不得不一遍又一遍地运行vagrant provision（有时多达6次）以完成整个构建而没有错误。然而，在极少数情况下，星星会对齐并且一切都会在第一次尝试时闪现。
我看到的错误通常是显式超时错误（尽管并非总是如此）。我通常从一个相当弱的办公网络连接（<20 Mbps以下）运行它，这可以解释为什么失败发生在最大的下载。
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需要多次vagrant provision吗？如果是这样，我该如何测试和治疗呢？第二，有没有办法让流浪汉保持供应，直到成功完成？我没有找到这样做的文件标记/设置，但感觉可能有一个......
感谢您的帮助。

带宽，CPU，I / O，错误都可能累积到资源收敛时间，这可能会导致超时。尝试增加VM（CPU，RAM）的资源，如果可能的话，在主机上使用SSD等等。
至于运行vagrant provision直到成功，你可能只需将它包装在while循环中：
false; while [ "$?" -ne "0" ]; do vagrant provision; done
