Start GlassFish Server

# /usr/share/glassfish4/glassfish/bin/asadmin start-domain domain1


Now the glassfish server is started. Glassfish server by default runs on 4848 port. Before login, you need to change the admin password and redirect to secure port.

# /usr/share/glassfish4/bin/asadmin change-admin-password


 Here it will ask for admin name, admin password, new admin password, confirm admin password. Remember glassfish default admin password is blank.


# /usr/share/glassfish4/bin/asadmin enable-secure-admin


Here it will ask for admin name, admin password gives this details and restarts glassfish.

Restart GlassFish Server

# /usr/share/glassfish4/glassfish/bin/asadmin restart-domain domain1


Now you can access URL: your_ip_address:4848 and log in with credentials.
