Preface

Preface

 

 

    Yesterday I implemented a three-nodes PXC,but there were some errors when proceeding it.So I decide to research what's wrong with it.The operations and evidences shows below.

    Today,I'm gonna implement a PXC,Let's see the procedure.

 

 

Procedure

Framework

 

 

Fisrt of all,I find out that yesterday's error is due to lack of "socat" package on first node zlm2.

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)
