  • Add new node in Cluster

    Team,

    Thanks

    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:
    Code:
    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:
    Code:
    wsrep_cluster_address=gcomm://IP1,IP2,IPn
