MySQL ERROR 157 (HY000)
If you are getting an error, while trying to set up MySQL cluster, and error says:
ERROR 157 (HY000): Could not connect to storage engine
than – there is a connectivity problem and issue. First thing first – check if your selinux is active or not (cat /etc/selinux/config) – if it’s active, either allow MySQL daemons to connect, or shut it off.
Thanks to the people over at http://linuxadminzone.com/ for sharing cluster setup tutorial; it is much clearer than it is from the MySQL documentation. Took me two hours to finish the whole thing.
