Umask was set to 0027 causing systemic permissions issues.


Before running the installer, set umask to 0022 by issuing this command:

Additional Information

If there was a previous VNA installation on the server, make sure you delete the /etc/my.cnf file.  Set the bash shell to umask 0022 and then run the installer.
