CentOS 6.5 (32位)设置定时关机
比如设置每天在20:00、22:00、23:00三个时间自动关机,两步搞定,如下。
1. 编辑 /etc/crontab 文件
在 /etc/crontab 文件末尾加入下面三行:
00 20 * * * root shutdown -h now
00 22 * * * root shutdown -h now
00 23 * * * root shutdown -h now
# vi /etc/crontab
... ...
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * user-name command to be executed
00 20 * * * root shutdown -h now
00 22 * * * root shutdown -h now
00 23 * * * root shutdown -h now
保存文件并退出。
2. 重启 crond 服务
# service crond restart
完毕!
