I want to run a rsync command between two servers on reboot can anyone suggest how can i do this??
Before the reboot or after the reboot?
If after the reboot just put an entry in cron, either crontab or cron.d with the time entered as "@reboot"
"@reboot /root/tools/some_action 1>>/some_log_file 2>>/some_error_file"
I have never done it before the reboot, but you could put in a custom shutdown script to perform the action.
Is there any other work around for this ??
Did the cron entry not perform the action?
Under Chef I would use a cron.d as a separate file controlled by a single Chef resource. For cron.d remember that you need to enter the account to run the command as in the entry.
Are these physical servers or virtual? If virtual, have you thought about using a shared drive? Then don’t need to sync. In AWS, you could use a shared s3 or EFS. If they are physical machines you could do an NFS share, maybe backed by some tech like DRBD or GlusterFS, or even SMB.
