mysql(8)

使用mysqlhotcopy 对mysql进行备份

在数据库段分配一个专门用于备份的用户

mysql> grant select,reload,lock tables on *.* to 'hotcopyer'@'localhost' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)

3、在/etc/my.cnf里面添加

[mysqlhotcopy]
interactive-timeout
user=hotcopyer
password=123456
port=3306

开始备份。

[root@localhost ~]# mysqlhotcopy t_girl t_girl_new
