Hi all,

Is it possible to setup a percona xtradb cluster with just one node? If yes. Is there anything to consider before?

Hope you guys help me…

Hello Buddy,

That’s a good question, I did it by editing /etc/my.cnf file.

Basically I removed lines that includes others directories.

running `show status like 'wsrep%';`

```auto
+--------------------------+----------------------+
| Variable_name | Value |
+--------------------------+----------------------+
| wsrep_cluster_conf_id | 18446744073709551615 |
| wsrep_cluster_size | 0 |
| wsrep_cluster_state_uuid | |
| wsrep_cluster_status | Disconnected |
| wsrep_connected | OFF |
| wsrep_local_bf_aborts | 0 |
| wsrep_local_index | 18446744073709551615 |
| wsrep_provider_name | |
| wsrep_provider_vendor | |
| wsrep_provider_version | |
| wsrep_ready | ON |
+--------------------------+----------------------+

```

I don’t know if it is the best way to do, Let me know guys if there is another way.

@Carlos,  
Yes, you can run a “cluster of 1” by simply bootstrapping that node. You always and only bootstrap the very first node of a PXC. So if you do this, then you have a cluster of 1.

My question is “why”? That’s not really a cluster, so why do you want only 1 node?
