google-cloud-storage - 如何从 crontab 正确运行 gsutil？

Question

这是我在/etc/crontab 中的条目，CentOS 6.6:

0 0 */1 * * fredrik /home/fredrik/google-cloud-sdk/bin/gsutil -d -m rsync -r -C [src] [dst] &> [log]

我收到此错误:OSError:[Errno 13]权限被拒绝:'/.config'

如果在 shell 中执行，该命令运行良好。我注意到如果没有 gsutil 的完整路径，我无法运行 0 0 */1 * * fredrik gsutil ... ，所以我假设我在 cron 所在的环境中丢失了一些东西正在运行...？

这是完整的回溯:

感谢 Mike 和 jterrace 帮助我完成这项工作。最后，我不得不修改这些环境变量:PATH、HOME、BOTO_CONFIG(除了任何其他默认变量)。

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/home/fredrik/google-cloud-sdk/bin
HOME=/home/fredrik
BOTO_CONFIG="/home/fredrik/.config/gcloud/legacy_credentials/[your-email-address]/.boto"

  0  0 */1 *  * fredrik   gsutil -d -m rsync -r -C /local-folder/ gs://my-bucket/my-folder/ > /logs/gsutil.log 2>&1

> gsutil.log 2>&1 将 stdout 和 stderr 通过管道传输到同一文件。此外，下次 gsutil 运行时它将覆盖日志文件。为了将其追加到日志文件中，请使用 >> gsutil.log 2>&1。这在 Linux 和 OS X 上应该都是安全的。

我注意到调试标志 -d 会在大量数据上创建大量日志文件，因此我个人可能会选择退出该标志。
