今天为公司新建的uat数据库备份时,出现了报错,将解决方法整理、做一下备忘:
服务器系统:
[[email protected] tmp]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) mysql版本号: 报错如下: [[email protected] tmp]# innobackupex --defaults-file=/etc/my.cnf --user=backup --password=****** --stream=tar /home/backup/ | gzip >/home/backup/`date +%F_%H-%M-%S`.tar.gz 171120 17:10:42 innobackupex: Starting the backup operation IMPORTANT: Please check that the backup run completes successfully. At the end of a successful backup run innobackupex prints "completed OK!". 171120 17:10:42 version_check Connecting to MySQL server with DSN ‘dbi:mysql:;mysql_read_default_group=xtrabackup‘ as ‘backup‘ (using password: YES). Failed to connect to MySQL server: DBI connect(‘;mysql_read_default_group=xtrabackup‘,‘backup‘,...) failed: Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2) at - line 1314. 171120 17:10:42 Connecting to MySQL server host: localhost, user: backup, password: set, port: not set, socket: not set Failed to connect to MySQL server: Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2).
解决办法:
在命令行中添加
--host=127.0.0.1
参数;
备注:网上有的说,通过
# find / -name "mysql.sock"
查到socket参数,然后在配置文件中修改,但测试后,不一定能解决问题。
