遇到上面的错误,应该是包没加,你看你添加perl-DBD-MySQL没有,如果添加了,还包这个错,你在查询一下 

yum deplist perl-DBD-MySQL|grep mysql 看下是否有依赖包没添加 

这个是我的:

dependency: libmysqlclient.so.16()(64bit)

   provider: mysql-libs.x86_64 5.1.73-5.el6_6

  dependency: libmysqlclient.so.16(libmysqlclient_16)(64bit)

   provider: mysql-libs.x86_64 5.1.73-5.el6_6

少了 mysql-libs,我在网上找了好久没找到5.6对应的(yum安装的是5.1的),后来在网上查资料知道了,原来在MySQL-shared-compat-5.6.23-1.linux_glibc2.5.x86_64.rpm里面有安装后在

/usr/bin/innobackupex --user=root --password=123 --defaults-file=/etc/my.cnf --databases='test' /tmp/backup/

成功了!!!!!!
