问题描述

我正在尝试使用 crontab 执行以下 shell 脚本:

I'm trying to execute the following shell script using crontab:

#!/bin/sh
cd /mnt/voylla-production/current
bundle exec rake maintenance:last_2_days_orders
bundle exec rake maintenance:send_last_2_days_payment_dropouts

crontab 条目是

The crontab entry is

0 16 * * * /mnt/voylla-production/releases/20131031003111/voylla_scripts/cj_4pm.sh

我在邮件中收到以下错误消息:

I'm getting the following error message in the mail:

/mnt/voylla-staging/current/voylla_scripts/cj_4pm.sh: line 3: bundle: command not found
/mnt/voylla-staging/current/voylla_scripts/cj_4pm.sh: line 4: bundle: command not found

我手动运行命令时没有收到错误消息.不知道这里发生了什么.有人可以指出.

I dont get the error when I run the commands manually. Not sure what's going on here. Could someone please point out.

谢谢

推荐答案

在 crontab 中正确设置所有环境的一个好技巧是使用 /bin/bash -l :

A nice trick to get all environment properly set up in crontab is to use /bin/bash -l :

0 16 * * * /bin/bash -l -c '/mnt/voylla-production/releases/20131031003111/voylla_scripts/cj_4pm.sh'

-l 选项将调用完整的登录 shell，从而读取您的 bashrc 文件及其执行的任何路径/rvm 设置.

The -l option will invoke a full login shell, thus reading your bashrc file and any path / rvm setting it performs.

如果你想简化你的 crontab 管理并使用这个技巧——以及其他技巧——而不必考虑它们，你可以使用 每当宝石.它也与 capistrano 一起玩得很好，如果你使用它，在部署时重新生成 crontab.

If you want to simplify your crontab management and use this trick - as well as others - without having to think about them, you can use the Whenever gem. It also play very nice with capistrano, if you use it, regenerating crontab on deploy.
