For libmysqlclient 5.5.28 vs 5.5.29 part, there is work in progress in MDEV-3882 and some discussion and explanation here https://lists.launchpad.net/maria-discuss/msg00699.html

Thanks Elena ro the reference but at the time beeing it seems not possible to run mariaDB-galera server on ubuntu,
I've tested on a CentOS 6 box and installation process is successful. I try to follow some tutorial for setting up a cluster with 2 nodes but as it was done on ubunutu server, I'm quite confused with the cnf files. In CentOS, the my.cnf includes files within my.cnf.d. There, I do not know exactly where to put directives into the server.cnf file as there is different section, do I have to put the galera directive for the cluster within the mysql section or maria-db or mariadb-5.5... I'm quite confused.

Thanks.

>> at the time beeing it seems not possible to run mariaDB-galera server on ubuntu,

I'm checking installation on a fresh precise right now, will update when done.

It looks like the only real problem is the one about libmysqlclient18, which is the same as MDEV-3882, and has the same workaround, see or example https://lists.launchpad.net/maria-discuss/msg00698.html
With aptitude, the following command works for me:

sudo aptitude -y install mariadb-galera-server-5.5 libmysqlclient18=5.5.28-mariadb-a1~precise mysql-common=5.5.28-mariadb-a1~precise

(assuming the galera library was already installed by the previous attempt)

Please try it out.

In regard to CentOS configs, it only uses ones from /etc/my.cnf.d/ because the top config /etc/my.cnf says to do so (it has includedir). You can add your galera configuration to any server-only section, be it mysqld, mariadb, mysqld-5.5, mariadb-5.5, into any cnf file, or create one of your own.

Thanks a lot Elena, your last aptitude command line is working on my new Ubunutu. I will now work on the cluster configuration. BTW, is there any good tutorial to set up a MariaDB galera cluster from scratch ?

Thanks.

There is Codership wiki for Galera http://www.codership.com/wiki/doku.php which has a lot of useful information, unfortunately its structure is not very obvious so it might be difficult to find what you're looking for.

Here is a presentation from Codership, IIRC it has configuration steps inside: http://www.slideshare.net/henrikingo/introduction-to-galera

Some time ago I ran onto this blog article http://www.sebastien-han.fr/blog/2012/04/01/mysql-multi-master-replication-with-galera/ which I found very good back then. It might be a little outdated by now (or maybe not, I didn't check), but I think it's still a useful read.

Since installation worked with the workaround for MDEV-3882, I'm closing this report as a duplicate of MDEV-3882.

Thanks Helena for all these useful links and information, I've found another one which could be interesting also : http://edin.no-ip.com/blog/hswong3i/mariadb-galera-mastermaster-replication-ubuntu-12-04-howto
