Preface

Preface

 

 

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

    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.

 

 

Framework

Procedure

 

 

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)

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

It
still show the ERROR output when node zlm3 startup.

    Choose the Linux-Generic
software.There’re three version relevant with openssl(100,101,102),I
choose the ssl102 version.
