2 去check 配置文件有无datadir配置参数。

[xxx@xxx-c001db1 sharding_setup_1]$ cat /xxx/xxx/xxx/5.5.25a/my.cnf |grep datadir

datadir=/mysqldata/data

看起来my.cnf里面已经配置了。

3 自定义备份制定my.cnf，试下看。

[xxx@xxx-c001db1 backup]$ time /usr/bin/innobackupex –rsync –user=”user” –password=”#xxx$” –defaults-file=/opt/xxx/xxx/5.5.25a/my.cnf /mysqldata/backup

4 OK，成功了，在innobackupex的命令行上面指定–defaults-file=/opt/xxx/xxx/5.5.25a/my.cnf既可解决此问题。
