"URGENT"How can i execute shell script from a remote server ?

amit.giri · 09-23-2009, 10:37 AM

Hi all,

Problem statement:I have configured passwordless ssh between two servers A & B.Now i want to start & stop one tomcat server(instaled on sever B) from server A.

I am executing this command: ssh serverA " sh cd {path to the directory where tomcat is installed) startup.sh"

Error message:"Neither the JAVA_HOME nor the JRE_HOME environment variable is defined At least one of these environment variable is needed to run this program."

But both java_home & jre_home is defined correctly on server-B in ~/.bash_profile.

Please provide help in this.
Regards
Amit giri

why is this urgent ? (i almost didnt click on it)

i would do:

Code:

ssh serverA "/path/to/startup.sh"

if that doesnt work

Code:

ssh serverA
/path/to/startup.sh

Agreed with the last poster... Very simple.

Just ssh into the box and run the script.

I am facing problems with the JAVA_HOME setup on server B.
The script that i want to trigger requires JAVA_HOME.

Now when i checked on server B for JAVA_HOME i found that it was configured correctly in ./bash_profile.

But if you want to run the command on server A, the variable should be defined there. Is not it? Or am I still missing something?

The problem is that you are trying to run a program on server A. The fact that server B is set up correctly has no bearing on the problem.

To run a program on server A, server A must be set up correctly, whereas server B's setup won't be of any benefit.

Your command --

Code:

ssh serverA " sh cd {path to the directory where tomcat is installed) startup.sh"

-- tries to start tomcat on server A, not B. Is this what you intended?

What about shell type/env setup?
SSH with and without command gives different results? env is different?

works as expected

Code:

[a ~]$ ssh 172.24.40.100
Last login: Mon Jan  1 06:07:24 2001 from 172.24.41.78
[b ~]# /path/script.sh

gives me error consistent with env setup

Code:

[a ~]$ ssh 172.24.40.100 /path/script.sh

Which implies the latter is running the script.sh on host a, when I want to
'launch' in from a, and 'run' it on b!?

your urgent question is fubar to begin with. just define the needed variables on the server you are running the command on.

AND.....the OP is gone. After getting help the OP does not even care to come back and say if the issue is resolved or not.

Hey i am still here but my problem get resolve by defining the JAVA_HOME explicitly in my script that i am executing. i.e i defined export JAVA_HOME="path to java_home on server B".

Anyways thanks alot for your precious time.
