centos 7.2

mysql 5.7.16

innobackupex version 2.4.6

[root@Devops-mysql-150-115 sh]# innobackupex --defaults-file=/app/mysql/servers/etc/ --user=root --password=xxxxxx /backup/mysql/

备份出现错误：（有2个提示）

1. Unrecognized character \x01; marked by <-- HERE after <-- HERE near column 1 at - line 1374.

google搜索后说bug。

170309 00:42:54 innobackupex: Starting the backup operation

Failed to connect to MySQL server: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'

看这个不像。

####错误具体信息：

IMPORTANT: Please check that the backup run completes successfully.

At the end of a successful backup run innobackupex

prints "completed OK!".

Unrecognized character \x01; marked by <-- HERE after <-- HERE near column 1 at - line 1374.

Failed to connect to MySQL server: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2).

######  解决方法：

指定sock文件位置就ok了

innobackupex --defaults-file=/app/mysql/servers/etc/ --socket=/app/mysql/data/mysql.sock --user=root --password=xxxx /backup/mysql/

备份成功
