Ok guys, I have tried the following five tutorials, mixed and matched, spent the past two days, over 30 hours trying to get this to work. I have spun up and down amazon ec2 instance after instance. Are these tutorials up to date? Is it possible they are missing something? I truly don’t see how I could get all of these tutorials wrong after starting from scratch so many times… Seriously, I need someone to try and get a 3 cluster node working on AWS EC2 using CentOS 6.3 ( because I do not think it is possible, and I am literally pulling my hair out… I see all these good people running Percona, and I am like what the hell over here… I have made sure selinux is disabled, I blantently have turned iptables off, added firewall rules for the security group, I can ssh to 4567, however, mysql doesn’t want to start on any of the clusters, except right after a reboot on the first node, using mysqld\_safe … Also, mysqld\_safe seems to be the only way I get any feedback from the app, otherwise, it just says Starting…ERROR with nothing in the logs… Please Please Please, will someone attempt a 3 node cluster using the above ami, and tell me if I am crazy or not… btw here are the links I followed that I mentioned earlier… [LIST] [_][URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/cenots\_howto.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/cenots_howto.html)”]Installing Percona XtraDB Cluster on CentOS[/URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/cenots\_howto.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/cenots_howto.html)”] [_][URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/singlebox.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/singlebox.html)”]How to setup 3 node cluster on single box[/URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/singlebox.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/singlebox.html)”] [_][URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/3nodesec2.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/3nodesec2.html)”]How to setup 3 node cluster in EC2 enviroment[/URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/3nodesec2.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/3nodesec2.html)”] [_][URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/haproxy.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/haproxy.html)”]Load balancing with HAProxy[/URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/haproxy.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/haproxy.html)”] [\*][URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/virt\_sandbox.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/virt_sandbox.html)”]Setting up PXC reference architecture with HAProxy[/URL=“[http://www.percona.com/doc/percona-xtradb-cluster/howtos/virt\_sandbox.html](http://www.percona.com/doc/percona-xtradb-cluster/howtos/virt_sandbox.html)”] [/LIST] ---

Greetings, You know i have set up this same setup using the same guides you have 20 times or so for customers, I was like hmm let me give this a shot yet again. The only difference is I am using the Rackspace Cloud. I am seeing the same issue I have fought with this for over 40 hours this past weekend. This is what i came up with as it is failing for me as well. I see it running but no /usr/bin/xtrabackup\_55 is being called on the donor, on the donor: [root@percona1 mysql]# which xtrabackup\_55 /usr/bin/xtrabackup\_55 As well i see that NC is running on both servers but no data is being transferred, in this state, well I am leaning towards this being a bug in xtrabackup 2.1.2. I hope that the devs or someone can chime in and give us some ideal on what happened this was working 2 weeks ago now its broke. Thanks, Will McInnis ---

I fixed it! kinda! If you followed the instructions it will installed 2.1.2! something in this version is bad!!! not sure yet, so to get mine to work here is what i did: Make sure that the master or node1 is STOPPED!!! ```auto wget repo.percona.com/centos/6/os/x86_64/percona-xtrabackup-2.0.7-552.rhel6.x86_64.rpm wget repo.percona.com/centos/6/os/x86_64/Percona-XtraDB-Cluster-server-5.5.30-23.7.4.406.rhel6.x86_64.rpm yum remove percona-xtrabackup #THIS will remove the cluster we software that is ok! rpm -ihv percona-xtrabackup-2.0.7-552.rhel6.x86_64.rpm rpm -ihv Percona-XtraDB-Cluster-server-5.5.30-23.7.4.406.rhel6.x86_64.rpm /etc/init.d/mysql start --wsrep-cluster-address="gcomm://" ``` If you have problems feel free to email me: ```auto will.mcinnis at rackspace.com ``` ---

As well you might want to disable the percona repo until this is fixed. ---
