Vagrant Chef Recipe Checksum Calculations - mysql

Question

I am running a mysql recipe that is failing. When I do vagrant up after a halt it claims that grants.sql template's checksum has changed causing it to re-run when it shouldn't.

Any ideas how these checksums are completed and how to fix this?

Answer 1

The best way to debug these issues is to take a look at the new file it created, in this case at /etc/mysql/grants.sql, and then to look at the backup at /var/chef/backup/etc/mysql/grants.sql.chef-20120328125848 (from the logs you posted). The backup is always made, so you can compare the contents of the two, and proceed to fix the Chef recipe to make sure it generates the same content.
