Preface
Today,I'm gonna implement a PXC,Let's see the procedure.
Framework
| Hostname | IP | Port | OS Version | MySQL Version | Xtrabackup version |
| zlm2 | 192.168.1.101 | 3308 | CentOS 7.0 | PXC 5.7.22 | 2.4.12 Linux (x86_64) |
| zlm3 | 192.168.1.102 | 3308 | CentOS 7.0 | PXC 5.7.22 | 2.4.12 Linux (x86_64) |
| zlm4 | 192.168.1.103 | 3308 | CentOS 7.0 | PXC 5.7.22 | 2.4.12 Linux (x86_64) |
Procedure
The official website of PXC:
Choose the Linux-Generic software.There're three version relevant with openssl（100,101,102）,I choose the ssl102 version.
Install Percona-XtraDB-Cluster software on three nodes.
