Hi all 

I'm having problems with the current beta not working with a 'mysql' server, I've built this version against the current MariaDB version (and the required devel versions) - all these servers are CentOS7 (fully updated): 

Installed Packages 
Name : MariaDB-server 
Arch : x86_64 
Version : 10.2.9 
Release : 1.el7.centos 
Size : 456 M 
Repo : installed 
Summary : MariaDB: a very fast and robust SQL database server 

Installed Packages 
Name : MariaDB-devel 
Arch : x86_64 
Version : 10.2.9 
Release : 1.el7.centos 
Size : 39 M 
Repo : installed 

# Percona cluster 

dnf info Percona-XtraDB-cluster-57 
Using metadata from Wed Oct 4 11:54:00 2017 

The database was created as per the documentation and all the tables and stored procedures exist, this is a single server. However when a machine requests an IP I'm seeing the following errors in the log file: 

2017-10-05 18:16:10.273 INFO [kea-dhcp4.dhcp4/24862] DHCP4_STARTED Kea DHCPv4 server version 1.3.0-beta started

I'm also trying to get this working with a Percona XtraDB cluster and having the same problem, this a a five server cluster:

In both of those cases on the cluster and the single server the error messages just keep repeating. There is also nothing in the leases table. 

Does anyone currently use a DB for lease data? Is there any more information I can provide about this problem? Is this likely to be something I've missed in building kea? Kea 1.3 beta does work OK using a file for lease storage. :) 

Regards 


Bill
