Reboot Linux server automatically at 2 a.m.

Creation of a cron job to restart the Ubuntu server.

I wanted to restart my Ubuntu server in the virtual machine automatically. No problem with a cronjob.

First, we connect to the server with a terminal via SSH. Then we can create the cronjob with the following command:

sudo crontab -e

The syntax of a cronjob is as follows:

minute hour day_of_month month day_of_week command

In our example, we now create the cronjob as follows

0 2 * * * * /sbin/shutdown -r now

We then save the file. We can perform a check with the following command:

sudo crontab -l
