/usr/bin - Configuration files to
/etcand the configuration file is now lower case:maxscale.cnf - Logs to
/var/log/maxscale - The module and library directory have been combined into a single directory in
/usr/lib64/maxscale. If you have custom modules please make sure they are located there. - Data directory is
/var/lib/maxscale. This is the default location for MaxScale-specific data. - PID file can be found at
