How do I install, create or edit my own cron job?

To edit or create your own crontab file, type the following command at the UNIX / Linux shell prompt:

$ export EDITOR=nano (optional)
$ crontab -e

Do I have to restart cron after changing the crontable file?

No. Cron will examine the modification time on all crontabs and reload those which have changed. Cron does not need to be restarted whenever a crontab file is modified.

Syntax of crontab (field description)

The syntax is:

1 2 3 4 5 /path/to/command arg1 arg2

Where,

• 1: Minute (0-59)
• 2: Hours (0-23)
• 3: Day (0-31)
• 4: Month (0-12 [12 == December])
• 5: Day of the week(0-7 [7 or 0 == sunday])
• /path/to/command – Script or command name to schedule

Easy to remember format:

* * * * * 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)

Create CronTab Script

Set the task execution time

Go to Crontab Guru.

Get Node install localtion

Write the following command in the terminal:

$ which node

Get application location in the system

Enter the following command in the application folder:

$ pwd

Add Backup Type (MySQL Or Wordpress)

If you work with environment variables, you should only set the value BACKUP_ENV to mysql OR wordpress.

This value is required in the command line if you are not working with environment variables. Add mysql OR wordpress after the app location.

For Example:

1 2 3 4 5 /path/to/node /path/to/app/file.js mysql

Add Execution environment

If you work with environment variables, you should only set the value NODE_ENV to develop OR production.

By default the value is production, so you can skip entering this value if you work from a production server.

IMPORTANT: If you work from a development server and you are not working with environment variables, this value is necessary in the command line, otherwise you will be working with the production values. Add develop after the backup type.

Develop Example (Without NODE_ENV):

1 2 3 4 5 /path/to/node /path/to/app/file.js mysql develop

Develop Example (With NODE_ENV = develop):

1 2 3 4 5 /path/to/node /path/to/app/file.js mysql

Production Example (With or without NODE_ENV = production):

1 2 3 4 5 /path/to/node /path/to/app/file.js mysql

Add output file for application logs (Optional)

If you want to keep a file for the executions of the application you must add the following to the end of crontab script

1 2 3 4 5 /path/to/node /path/to/app/filefile.js mysql develop >> /path/to/logs/log-file.log 2>&1

Full Example

* * * * * ${which node} ${pwd-application}/${filename}.js ${backup-type} ${env} >> ${pwd-logs-location}/${log-filename}.log 2>&1

Full Example Without Crontab

node ${filename}.js ${backup-type} ${env}
