Shell Programming and Scripting

Hi folks,

I am running a shell script it asks for username and password to stop some service, I need to write some script that it will read username and password from my shell script and then sucessfully stop services without prompting username/password query.

Hello,

You can create a script for stopping and starting instances. You can provide sudo access to the user which don't have access to stop/start services, there you can give nopassword authority to user and by this way script shouldn't ask you username and password then.

Currently i am using below code. But it is not working properly.

Code:

stop-service.sh

USERNAME=username
PASS=pass123
./stopservice.sh << EOF
$USERNAME
$PASS
EOF

Hello,

It is never recommended to hardcode a password in a script.
Let me give you an example here.

Lets say you are using a user named user1 and services are owned by user user2. So create script for simple stopping and starting services and make owner as user2 (Note: if you don't have permissions for that you can contact root for same).

Then root can give you access for

Code:

 sudo

with non password option there. This means you will be able to run script with user1 (Which actually don't have access to STOP and START services directly) but this

Code:

sudo

access will give user1 ability to do so.



kindly let me know if I can help you further on same.

Dear

When i run below script script it ask me username and password.

Code:

./stop-service.sh

That password not belong to any application, it is database password which i need to put in some script so it will not prompt me for username/password and stop service with script.

Hello,

Here you can edit

Code:

edit /etc/sudoers

and then you can give

Code:

username ALL=(ALL) NOPASSWD: ALL

there now if you will run the script it shouln't ask you password.

Same explaination is given in prvious post too.



Thanks,

Dear Sir,

It is not operating system password, i am telling you, it is database username and password which i need to provide in script so it will not ask me password, it is not related with sudo or any other operating system level thing, it is asking for two arguments username/password which i need to put in script so my service got stop automatically.
