我有一个计划每 4 分钟运行一次的 cronjob。Cron 运行正常，但无法执行它应该运行的 .sh 文件。Cron 规则如下:

*/15 * * * * cd /var/www/html/etl_project && ./run_etl_incomplete.sh >> /var/www/html/etl_project/cron_log.txt 2>&1

在 cron_log.txt 我收到以下权限被拒绝错误:

/bin/sh: 1: ./run_etl_incomplete.sh: Permission denied
/bin/sh: 1: ./run_etl_incomplete.sh: Permission denied
/bin/sh: 1: ./run_etl_incomplete.sh: Permission denied

我假设它是您自己用于此 cron 的个人用户，它没有执行该文件的权限。也许该文件是作为 root 用户或其他用户创建的，因此未设置凭据以允许您的用户执行。

首先 - 尝试检查文件上设置了哪些权限

ls -l /var/www/html/etl_project/ | grep run_etl_incomplete.sh

检查输出以查看谁是所有者和组以及设置了哪些权限。

要使文件可执行 -

chmod +x /var/www/html/etl_project/run_etl_incomplete.sh

仅当您首先具有正确的权限(例如，如果您的用户是该组的一部分)来修改文件时，这才有效。
一旦文件成为可执行文件，您的 cron 将运行。
