innobackupex 备份出现异常

备份问题：[root@ppdb01 backup]# innobackupex --defaults-file=/home/h5act3306/my.cnf --user=root --password=dba默认密码  --host=127.0.0.1 --port=3306 --slave-info /data/backup/

[root@ppdb01 backup]# innobackupex --defaults-file=/home/h5act3306/my.cnf --user=root [email protected]#  --host=127.0.0.1 --port=3306 --slave-info /data/backup/

IMPORTANT: Please check that the backup run completes successfully.
           At the end of a successful backup run innobackupex
           prints "completed OK!".

Using server version 5.7.19-17-log
The --slave-info option requires GTID enabled for a multi-threaded slave.

解决方法：

方法1、innobackupex --defaults-file=/home/h5act3306/my.cnf --user=root --password=dba默认密码  --host=127.0.0.1 --port=3306  /data/backup/

 去掉 --slave-info参数。

方法2、

关闭并行复制功能

mysql> show variables like '%parallel%';

+----------------------------------+----------------+

| Variable_name | Value |

+----------------------------------+----------------+

| innodb_parallel_doublewrite_path | xb_doublewrite |

| slave_parallel_type | LOGICAL_CLOCK |

| slave_parallel_workers | 16 |

+----------------------------------+----------------+

3 rows in set (0.00 sec)

mysql> exit

在 my.cnf文件里把这两行注释

#slave-parallel-type = LOGICAL_CLOCK

#slave-parallel-workers = 16

重启mysql实例

注：开户git_id 并行复制可以降低延迟。也可以不用关闭并行复制
