Run script on different computers - Overclock.net

dharmaBum · 3 Weeks Ago

Here's the setup:
I'm working with several different servers: a file server, web server, admin server (LDAP), a backup server, ect. These are somewhat ad-hoc and not part of an "over-arching" network (apart from the department, but these only belong to a small-subset of that). There's also an off-site cluster that is used.

Here's the problem:
When some new user needs to be added, I need to manually add them to each server. I need to give them directories on the file server, set up their web folders on the web server, set up their access on the LDAP server, ect.

I've automated this to running a single script on each server, but still have to jump to each individually and run the respective add user code. This can get tedious when there's a big group of new users to add.

Here's the question:
I'm curious as how to automate this into a single script that will run all these server-specific scripts automatically.

My ideas so far:
The solution I'm cobbling together inside my head is to set up a small daemon on each server and broadcast an "add user someuser" command from a central location, and have each server daemon act accordingly.

Is there a more straight-forward way to do this?

Doesn't seem like it would be that hard, but I would have to look into it. Sorry.

SSH to the machines, no point running around to them.

if your machines are setup correctly with passkeys then this is an over simplified way of doing what you need

script on you machine

Code:

file name addnewusers

#!/bin/bash

scp userstoadd.txt useraccount@ipaddressoffileserver:userstoadd.txt
ssh useraccount@ipaddressoffileserver ./addusr

scp userstoadd.txt useraccount@ipaddressofwebserver:userstoadd.txt
ssh useraccount@ipaddressofwebserver ./addusr

scp userstoadd.txt useraccount@ipaddressofadminserver:userstoadd.txt
ssh useraccount@ ipaddressofadminserver./addusr

scp userstoadd.txt useraccount@ipaddressofbackupserver:userstoadd.txt
ssh useraccount@ ipaddressofbackupserver./addusr

scp userstoadd.txt useraccount@ipaddressofclusterserver:userstoadd.txt
ssh useraccount@ ipaddressofclusterserver./addusr

text file with user names on you machine

Code:

file name userstoadd.txt
last line in file is "end"

tom
bill
frank
sandy
sherry
lynn
jeff
end

script on remote machine

Code:

file name assusr

#/bin/bash
count=1
usersname=$(tail +$count userstoadd.txt | head -n1)
while [ "$usersname" != "end" ]
do
	#./xz
	echo "$count user named $usersname added"
#	./ADDUSERSCRIPT $a
	count=`expr $count + 1`
	usersname=$(tail +$count userstoadd.txt | head -n1)
done
exit

your script using command line argument as user name

Code:

file name ADDUSERSCRIPT

#/bin/bash
useradd $1
passwd $1

just an example
