流浪厨师食谱校验和计算

Question

我正在运行一个失败的 mysql 配方。当我在停止后做 vagrant up 时，它声称 grants.sql 模板的校验和已更改，导致它在不应该重新运行时重新运行。

知道这些校验和是如何完成的以及如何解决这个问题吗？

调试这些问题的最佳方法是查看它创建的新文件，在本例中为/etc/mysql/grants.sql，然后查看/var/chef/backup/etc/mysql/grants.sql.chef-20120328125848 的备份（来自您发布的日志）。始终会进行备份，因此您可以比较两者的内容，然后继续修复 Chef 配方以确保它生成相同的内容。
