MySQL高可用之PXC安装部署（续）
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.
Procedure
Fisrt of all,I find out that yesterday's error is due to lack of "socat" package on first node zlm2.
