Fail when you startup Application First time on UNIX

It you see the error message:

when running:
asadmin start-domain domain1

mkdir /var/appserver (I didn't have to do this but maybe you do.)
mkdir /var/appserver/domains
asadmin create-domain --domaindir /var/appserver/domains --adminport 4848 --instanceport 8080 --adminuser admin domain1

Then you will see:
Please enter the admin password>
Please enter the admin password again>
Please enter the master password>
Please enter the master password again>
