Centos Crontab错误命令

Question

I have a pretty simple db back-up script that runs perfectly from shell. 我有一个非常简单的数据库备份脚本，可以从shell完美运行。

php /home/db_backup/db_backup.php

When I attempt to add a Crontab, I get the vague 'Bad Command errors in crontab, can't install." 当我尝试添加Crontab时，出现了模糊的“ crontab中的错误命令错误，无法安装。”

I've tried w/ php and full path to php. 我试过w / php和php的完整路径。

which php

returns /usr/bin/php 返回/ usr / bin / php

* 1 * * * php /home/db_backup/db_backup.php

* 1 * * * /usr/bin/php /home/db_backup/db_backup.php

Both return the same error. 两者都返回相同的错误。

Centos 6.6. Centos 6.6。 logged in as root. 以root用户身份登录。 Editing crontab thusly 从而编辑crontab

crontab -e

Spent too many hours trying to get this working. 花了太多时间试图使它正常工作。 What am I missing? 我想念什么？

Answer 1

I bet your problem is when editing the crontab file not with the commands itself. 我敢打赌，您的问题是在不使用命令本身编辑crontab文件时。

Be sure to let a blank line at the end of file. 确保在文件末尾留空行。

I mean the cursor must be in an empty line after the last entry. 我的意思是光标必须在最后一个条目之后空行。
