Sorry, the title should be:
How to remote start another script that located in another server in a script.

[Tim Nelson · Accepted solution]

ssh host scriptB
or
remsh host scriptB

If scriptB requires interaction with tty then this will not work.

Hi Tim

Thank you very much for your fast reply, Does you mean:

In ServerB, scriptB I just add below items and could remote start scriptA on serverA?


serverB > # cat scriptB
...
remsh serverA /home/oracle/scriptA.sh

exit

that's everyting? what't the remsh passwd?

[Tim Nelson]

1) Yes the script would look like you indicated.

2) In order for remsh to work without a password prompt you need to correctly configure the trust relationship. i.e. configure ./rhosts in users home directory.

For ssh you need to configure .ssh/authorized_keys file.


trust access is a different subject from your topic but can describe if needed.

[Gary L]

Yes, .rhosts is what i am thinking about.

thanks a lot.

It works now,

BTW,

the file should be .rhosts not ./rhost right?

[Tim Nelson]

yes plural.

$HOME/.rhosts

format:
hostname username

[Gary L]

thanks Tim.

One more question,

If I remote access to serverA but this server need enter some enviroment parameter like d0 [DEV50] d1 [DEV51], normally, the oracle user will enter d0 or d1 after input username and passwd and then in the DEV50, oralce could run the script serverA.
How to write this in scriptB, in other words, how to let the script execute d0

remsh serverA
d0 ???
sh scriptA

[Tim Nelson]

tty interaction with this is a problem.

I would recommend passing variables into the script. You will have to mod the script to accept these args and set the vars you want.

i.e.

remsh serverA "script.ksh arg1 arg2"

[Dennis Handly]

One thing to remember about remsh in a script, you should use the -n option so it doesn't eat up your commands following the remsh:
remsh machine -n command

hi,

in case, you decide to use SSH, below an extrace from a script that we currently use here:
...
ssh applnuser@SRV1 << EOF
/home/yogeeraj/compile.sh /appln/$4/$2/$3/$1
EOF
else
...

hope this helps too!
kind regards
