Cron jobs in a VPS server are set by editing the system’s crontab file. Here’s a general step-by-step guide on how to achieve this. It’s assumed that you are using a Unix-like VPS server.
1. Log in to your VPS server via SSH.
1. Once logged in, you need to open the crontab file. To do this, type the following command into your terminal and press Enter:
`crontab -e`1. You should now be in the crontab file. Here, add your cron job by adding a new line (this follows a specific syntax):
\`\`\` - _ _ _ _ command to be executed - – - – - | | | | | | | | | ——- Day of week (0 – 7) (Sunday=0 or 7) | | | ———- Month (1 – 12) | | ————- Day of month (1-31) | —————- Hour (0 – 23) ——————- Minute (0 – 59) \`\`\` Here, replace “command to be executed” with the command you want to be executed at a regular interval. For example, if you want to execute a script located at /home/user/script.sh every day at 5 AM, the line would be: `0 5 * * * /home/user/script.sh`1. After adding your cron job to the list, save the file and exit the editor. If you’re using Nano, you do this by pressing CTRL + X, then Y and finally Enter.
1. The cron job is now set. You can view your current list of cron jobs by using the command:
`crontab -l`It’s important to note that you need to have the appropriate permissions to add or modify cron jobs. This approach works for individual users’ cron jobs, and for system-wide jobs you’ll need to use `/etc/crontab` or files under `/etc/cron.d/`, and probably need administrative (root) permissions.
