停止集群

如果有集群如mha，要停止集群，因为备份结束时会产生一个长锁，集群软件侦测到一定时间里没响应会认为master发生了故障，从而触发迁移，这不是我们想看到的~因为这会导致新恢复出来的数据不一致

所以有集群的情况下，最好停止集群

Tip: 如果是mha，可以参考以下命令

masterha_check_status --conf=/etc/app1.cnf
masterha_stop  --conf=/etc/app1.cnf

开始备份

[root@upgrade-master ~]# time nohup /usr/bin/innobackupex --defaults-file=/etc/my.cnf  --user=root --password=xxxxxxxx  /mnt/mysqlbak/masterdb.full.backup  >> /tmp/masterdb.full.backup.log  2>&1   & 
[1] 890
[root@upgrade-master ~]#

分别下载同版本mysql，和目标版本(高版本)mysql
