  • MySQL高可用之PXC安装部署

     
    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.
