运行cronjob时被拒绝

Question

我有一个计划每4分钟运行一次的cronjob.Cron正常运行但是它无法执行它应该运行的.sh文件。遵循以下规则：

*/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中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

Answer 1

我假设您自己的个人用户正在使用此cron，该cron无权执行该文件。也许该文件是以root用户或其他用户身份创建的，因此凭据未设置为允许用户执行。

首先 - 尝试检查文件上设置的权限

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。

使文件可执行 -

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

仅当您首先拥有正确的权限（例如，如果您的用户是该组的一部分）才能修改文件时，此功能才有效。 一旦文件可执行，你的cron就会运行。
