how to set up rsync user to run a rsync script

Posted on 2016-07-14

I have two application servers clustered behind a load balancer on aws. Both of them connect to a ldap server for authentication.

I have a rsync script to run on the second application server to sync the cache folder from the first server. I can run the rysnc script under root user without problem. But how can I add it to cron job to run it automatically. Do I need a special user to run it or I can run it under "root" user?

Also, I think I need implement keyless ssh authentication. How could I do it?

thanks.

Hi!

You can run a cron job under root user as well as any other user.
To create and edit a cronjob you simply issue
crontab -e 

Open in new window

to list the cronjob of a user the you simly issue
crontab -l 

Open in new window

See further examples here

To setup ssh keyless login look here

I got the following error after I copied the id_rsa.pub key to the authorized_keys file on the remote host.
