If you initialized the first PXC node, so it’s standalone primary node, then adding new nodes is very simple. On a new node, you just specify the existing node’s IP in this variable:

```auto
wsrep_cluster_address=gcomm://node1_IP>

```

Then full SST will copy data from existing node to a new node, eventually making both nodes identical.  
Once all machines are joined into a cluster, then add all the IPs in the my.cnf on each node:

```auto
wsrep_cluster_address=gcomm://IP1,IP2,IPn

```
