Calling a remote shell script and applying a DB dump
Hi All,
I have a requirement to call a remote shell script to apply a db dump. The remote shell script will reside in the /root/admin/bin directory and the database dump will be copied by the script from another area to /root/admin/var.
the script will then invoke mysql to apply the db dump.
1). Can I setup a ssh public/private key against a root user on the remote server or do I have a to create another user to own the script on the remote area as well as a directory to hold the dump also own by the same user.
I say this because I know that it is not possible to loggin to a server as root it has to be another user eg. fbloggs
2). In my remote shell I have various SQL operations as part of the dump is there a way to test the success of all SQL operations in a shell script sql block rather than applying a test against each individual SQL operation.
Many thanks

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
