Hi, since some says now i try to start a Percona XtraDB Cluster on Ubuntu 16.04. I started with these instructions: [url][https://www.percona.com/doc/percona-xtradb-cluster/LATEST/install/apt.html[/url]](https://www.percona.com/doc/percona-xtradb-cluster/LATEST/install/apt.html%5B/url%5D) but it seems they are partially outdated. Adding wsrep variables to /etc/mysql/my.cnf does not really work, i added these variables to /etc/mysql/percona-xtradb-cluster.conf.d/mysqld.cnf, maybe that is not correct?. So i ran through this instructions step by step and changed variables to my meet my environment. I could bootstrap the first node successfully, but when i start a second node, the wsrep\_cluster\_size wont rise to “2” and when i create a new database it is not synced to the 2nd node. Can somebody please give me a hint, what i did wrong? My Configs are 1. Node: wsrep\_provider=/usr/lib/libgalera\_smm.so wsrep\_cluster\_name=DB-Cluster wsrep\_cluster\_address=gcomm://192.168.0.61,192.168.0.62,192.168.0.63 wsrep\_node\_name=DB-1 wsrep\_node\_address=192.168.0.61 wsrep\_sst\_method=xtrabackup-v2 wsrep\_sst\_auth=sstuser:S0meSecurePa$$w0rd! pxc\_strict\_mode=ENFORCING binlog\_format=ROW default\_storage\_engine=InnoDB innodb\_autoinc\_lock\_mode=2 2.

Can you share the error/mysqld.log for node-2. How big is your DB. Wondeing if SST is taking time. ---

The problem was simple: i edited .cnf file in /etc/mysql/ but there is a predefined wsrep.cnf file for these wsrep variables in /etc/mysql/percona-xtradb-cluster.conf.d/ wich overrides everything i added to any other .cnf File. No wonder why the cluster wont come up, because of this config File! Now i have a working cluster. Sorry for the delay here. ---

No probs. Good to hear you have working cluster. Enjoy PXC.
