我们可能不希望每次想要同步时都手动运行此脚本,因此下一步是自动执行此操作。假设您想每天晚上 11 点运行此脚本。要使用 Rocky Linux 实现自动化,使用 crontab:
crontab -e
这将调用 cron,可能如下所示:
# 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
