The scheduled reboot of Embedded Linux under the friendly ARM Micro2440 recently used timed restart for the ARM server in the internship company, so I checked the relevant information today. I found that there was no specific method for my current development platform, so I developed a set of methods for everyone to learn from each other. Embedded Linux under the friendly arm Micro2440 comes with the crontab command, but it is not enabled by default. You can refer to the following command to implement the timed restart function. # Config reboot time www.2cto.com 1. mkdir-p/var/spool/cron/crontabs/2. cp/sdcard/bin/root/var/spool/cron/crontabs/3. crond start4. crontab-l Command 1: Create a directory. the absolute path is/var/spool/cron/crontabs/, where all crontab configuration files are stored. Command 2: add a configuration file named "username as the file name" to the created directory. here, I copied the prepared configuration file www.2cto.com. Command 3: enable the cron service, from the file name, we found this is a daemon command 4: Display our configuration information. below is the information in the root of my configuration file: 0 4 *** reboot anyone who understands the crontab command knows that, the configuration information indicates that the reboot command is executed at four o'clock every morning.
