Percona XtraDB Cluster (hereinafter referred to as PXC) is an open source MySQL high-availability solution. It integrates Percona server and Percona xtrabackup with the Galera library to enable synchronous multi-master replication. The topology of each node is as follows:

Therefore, try to manually complete the Xtrabackup backup and restore and add the nodes to the cluster.Scene:There are three clean CentOS 6 servers, IP configured as: 192.168.166.169,192.168.166.170,192.168.166.171, ready to build three nodes of Percona
