如何创建cron作业以运行ruby脚本？ [英] how to create a cron job to run a ruby script?

问题描述

我想创建一个cron作业来运行ruby脚本。这就是我放在crontab中的内容。

I want to create a cron job to run a ruby script. this is what i have put in the crontab.

2 * * * * ruby /home/mark/project/script.rb >> /home/mark/cronOutput.txt

但它没有运行。我认为cron以root身份运行时环境会出现问题。

But its not running. I think there's some problem with the environment getting loaded up when the cron runs as root.

请帮助。

推荐答案

如果您的红宝石不符合标准然后，我个人希望将路径保存在shell脚本中，从而确保所有路径等。正确设置我的ruby程序需求，并在crontab中安排脚本。做类似

If your ruby is in non standard paths then personally I like to wrap my ruby calls in a shell script, thereby ensuring that all the paths etc. my ruby program needs are set correctly, and schedule the script in crontab. Do something like

2 * * * * /home/mark/project/ruby_wrapper_sh >> /home/mark/cronOutput.txt 2>&1

和您的/ home / mark / project / ruby​​_wrapper_sh应该读取类似

and your /home/mark/project/ruby_wrapper_sh should read something like

#!/bin/bash

. ~mark/.bash_profile 
`ruby /home/mark/project/script.rb`
