Upgrade of fpmmm tarball from 1.x to 2.1.0

There are some changes in the configuration file (fpmmm.conf):

  • The access rights should be change as follows: chmod 600 /etc/fpmmm.conf
  • The key Methode was spelled wrong in the configuration file. It was renamed to Method.
  • The key PidFile is ambiguous which could lead to problems and bugs. Thus it was changed to either MyPidFile for fpmmm and DbPidFile for the database.

Upgrade with DEB/RPM packages should happen automatically. For tarballs follow this:

shell> cd /opt
shell> tar xf /download/fpmmm-2.1.0.tar.gz
shell> rm -f fpmmm
shell> ln -s fpmmm-2.1.0 fpmmm
