Ubuntu 服务器上的 CronJob

尝试为我的服务器上正在运行的两个应用程序配置两个 CronJob。

我必须在 ConrJob 上放置的命令是：

wget -q -O- http://myDOMAIN/cron/index

我已经做了：

crontab -e

对文件的编辑：

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
*/1 * * * * wget -q -O- http://myDOMAIN/cron/index
*/1 * * * * wget -q -O- http://myDOMAIN2/cron/index

但是我没有收到来自 APP 的成功邮件通知。在 Maildir 文件夹 /home/master/（自己的邮件服务器）中，我仅收到以下消息：

/bin/sh: 1: /myDOMAIN/cron/index: not found

答案1

cronjobs 需要完整路径：尝试
/usr/bin/wget -q -O- http://myDOMAIN/cron/index
或
/usr/bin/wget -q -O-http://myDOMAIN/cron/index2> $logfile
并将 $logfile 添加到您的邮件中

答案2

您可以为此使用脚本（例如，类似这样的脚本cron.sh）：

在脚本中，添加所有想要运行的行为：

#!/bin/bash
wget -q -O- http://myDOMAIN/cron/index
wget -q -O- http://myDOMAIN2/cron/index

然后chmod a+x /path/to/croh.sh

最后，将以下内容添加到您的 crontab：

*/1 * * * * /path/to/croh.sh
