I am sorry to tell you that your advice did not work.
I could login mysql with mysql -u root -p
I executed the script /opt/processmaker-3.2.1-0/use_processmaker
I then execute the command mysql -u bn_processmaker -p bitnami_processmaker bitnami_pm. But it seems that there is something wrong. The output was the help guide of the command mysql.
I then login with mysql -u root -p and execute the command
UPDATE mysql.user SET authentication_string=PASSWORD('passwd') WHERE User='bn_processmaker';
and change the passwd in databases.php to passwd.
when I access to http://localhost/sysworkflow/en/neoclassic/login/login
the result is still
[wrapped: connect failed [Native Error: Access denied for user 'bn_processmaker'@'localhost' (using password: YES)] [User Info: bn_processmaker]]

Actually, my objective is to migrate my ProcessMaker 3.2.1 development from Bitnami Window version to Linux Bitnami. Grateful if you can advise me the proper procedures.
