linux中crontab工具开启服务

首先确认服务器是否开启任务计划服务，只有root用户才能对crond服务进行开启和关闭[[email protected] ~]# service crond status
crond (pid  1758) is running...
[[email protected] ~]# service crond stop
Stopping crond:                                            [  OK  ]
[[email protected] ~]# su - hongjie
[[email protected] ~]$ service crond status
crond is stopped
[[email protected] ~]$ su - root
[[email protected] ~]# service crond start
Starting crond:                                            [  OK  ]
[[email protected] ~]# service crond status
crond (pid  2805) is running...
[[email protected] ~]# su - hongjie
[[email protected] ~]$ service crond status
crond (pid  2805) is running...

开启服务后即可写运行脚本，运行脚本需要x执行权
