    I am not sure what kind of cluster you used in your env, galera
    cluster for mysql or MariaDB galera cluster? how did you configure
    and start the galera cluster?<br>
    I set MariaDB galera cluster up successfully before. And here is my
    understanding on the notes:<br>
    After installed and configured,<br>
    1. Start the first node with galera_new_cluster, but the left nodes
    use service mysql start.<br>
    2. Turn on the firewall&#39;s ports accordingly on each node. <br>

    <br>
    For debug purpose, you can comment out the nodes in gcomm and change
    it to be &quot;wsrep_cluster_address=gcomm:/<wbr>/&quot;, then try to start it and
    the wsrep_cluster_size<br>
    should be 1 if successfully.<br>

                        &gt; Hi,<br>
                        &gt;<br>
                        &gt; Anybody has been able to set up a Galera
                        cluster with the latest available<br>
                        &gt; version of Galera?<br>
                        &gt;<br>
                        &gt; Can anybody paste the configuration?<br>
                        &gt;<br>
                        &gt; I have tested it but I have not been able
                        to make it run resiliently.<br>
                        &gt;<br>
                      </span>Can you be more specific on why it wouldn&#39;t
                      run &quot;resiliently&quot;?<br>
                      I just saw you&#39;ve asked question on codership
                      group re. bootstrapping the<br>
                      cluster, is it related?<br>
                      <span><br>
                        &gt; Any help will be welcome!<br>
