[SOLVED] Automating mkdir, chmod and scp across all the servers

Issue

This seems to be a simple issue but, I'm not able to figure it out. I am trying to run a couple of small scripts on a server and i'm having issues with that. i have an allhosts file that has the list of servers which is in the same location as that of the .sh file.

script to create a directory structure across all the 20 servers with 777 permissions

#!bin/bash
for q in `cat allhosts`
do
ssh $q "mkdir -p /opt/acd/hgf/tom/hanks/"
chmod -R 777 $q "/opt/acd/hgf/tom/hanks/" >/dev/null 2>&1
done

in the above script, it is only creating the directory paths and not changing the permissions for that path. I tried running that chmod command in a separate script, but no use..

script to scp the contents of hanks to the hanks folder created in the new server.

#!bin/bash
for q in `cat allhosts`
do
scp /opt/acd/hgf/tom/hanks/* $q:/opt/acd/hgf/tom/hanks/ >/dev/null 2>&1
done

in this script too, when i run it, its not copying anything to any of the servers.

i know this is a very small issue, but please check and let me know where I am going wrong. thanks in advance..

Solution

The first script is failing because it is running the chmod on the local machine. You should run it on the remote machine via ssh - you could combine this with the other ssh invocation as follows:

ssh $q "mkdir -p /opt/acd/hgf/tom/hanks/ ; chmod -R 777 /opt/acd/hgf/tom/hanks/"

I'd guess the second script is failing because the first script isn't setting permissions; it looks okay.
