Glassfish Admin Password Management and Command Login without password

Introduction

we can use the asadmin utility to perform administrative tasks for Oracle GlassFish Server from the command line or from a script.

Path to the asadmin Utility

The asadmin utility is found in the glassfish installation directory

${glassfish_install}/bin/asadmin
asadmin> 

Upon running the command you enter the asadmin> console which enables to perform various administrative tasks

Inorder to run any command the adadmin utility will ask admin username and password

adadmin>asadmin list-applications
Enter admin user name>  admin
Enter admin password for user "admin"> 

The commands are executed once the username and password is validated

To change the admin password run the following command

asadmin> change-admin-password --user admin

If we want automated scripts to handle various administrative task we need that password need not be entered from stdin

Instead of typing the password at the command line, you can access the password for a command from a file such as passwords.txt.

The --passwordfile option of the asadmin utility takes the name of the file that contains the passwords.

The entry for a password in the file must have the AS_ADMIN_ prefix followed by the password name in uppercase letters.

Example password file is as follows:

AS_ADMIN_ prefix=1234

For example to run deploy command via scripts we can execute

./asadmin deploy $war --user admin --passwordfile  /opt/password.txt
