Provide Password using to the application using the shell script
Hello,
I have a requirement to shut down and start up my application on different environments (Dev, QA and Prod).
I have around 24 servers. I have to login to each server manually for shutinng down the application.
I wrote a shell command on each server and I am invoking those shell scripts from one server and shutting down.
Here is the issue now. I have problem in shutting down few servers using shell scripts because they need password before it shutdown.
I am executing the shell scripts with root access.
Is there any way that I can issue the password in the Shell itself so that the application will read the password from the shell script itself when it required?
I am new to this forum and LINUX as well. Need help to fix that instance so that my job will become easy
here is the shell script I am using to shut down my node
#!/bin/sh
############################# STOP NODES ###############################################
#stop the node node1
cd /opt/app/node1/bin/
./stopnode1.sh
#########################################################################################
Thanks in advance
Regards,
Raju

CHSH(1) User Commands CHSH(1)
NAME
chsh - change login shell
SYNOPSIS
chsh [options] [LOGIN]
DESCRIPTION
The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
the login shell for her own account; the superuser may change the login shell for any account.
OPTIONS
The options which apply to the chsh command are:
-h, --help
Display help message and exit.
-R, --root CHROOT_DIR
Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.
-s, --shell SHELL
The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.
If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.
NOTE
The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
back to its original value.
FILES
/etc/passwd
User account information.
/etc/shells
List of valid login shells.
/etc/login.defs
Shadow password suite configuration.

chfn(1), login.defs(5), passwd(5).
