"精神错乱：一遍又一遍地做同样的事情并期待 不同的结果"——阿尔伯特·爱因斯坦
我有一个 vagrant + chef （w/chef-zero Berkshelf） 构建的盒子，它运行很多程序，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（vagrant destroy后）发射这个盒子通常需要多次尝试。vagrant up将在上面列出的程序之一上失败，我将不得不一遍又一遍地运行vagrant provision（有时多达 6 次）才能完成整个构建而不会出现错误。然而，在极少数情况下，星星对齐，一切都会在第一次尝试时点燃。
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 向下）运行它，这可能解释了为什么故障发生在最大的下载中。
所以我的问题来了：首先，除了网络连接之外，还有其他变量可以解释为什么我必须多次vagrant provision？如果是这样，我该如何检测和治疗它？其次，有没有办法让流浪者继续供应，直到它成功？我还没有找到这样做的记录标志/设置，但感觉可能有一个......
感谢您的帮助。

带宽、CPU、I/O、错误，所有这些都可能累积到资源收敛时间，这可能会导致超时。尝试增加虚拟机的资源（CPU、RAM），如果可能，请在主机上使用 SSD 等。
至于运行vagrant provision直到成功，您可能只需将其包装在 while 循环中：
false; while [ "$?" -ne "0" ]; do vagrant provision; done
