+# This is a simple example of wsrep notification script (wsrep_notify_cmd).
+# It will create 'wsrep' schema and two tables in it: 'membeship' and 'status'
+# and fill them on every membership or node status change.
+#
+# Edit parameters below to specify the address and login to server:
+#
+USER='root'
+PSWD='rootpass'
+#
+# If these parameters are not set, then the values
+# passed by the server are taken:
+#
+HOST="127.0.0.1"
+PORT=3306
+#
+# Edit parameters below to specify SSL parameters:
