innobackupex 使用说明

1、创建备份相关用户

create user 'backuper'@'127.0.0.1' identified by '123456';
grant reload,lock tables,replication client,process,super on *.* to 'backuper'@'127.0.0.1';
grant create,insert,select on percona_schema.xtrabackup_history to 'backuper'@'127.0.0.1';

create user 'backuper'@'localhost' identified by '123456';
grant reload,lock tables,replication client,process,super on *.* to 'backuper'@'localhost';
grant create,insert,select on percona_schema.xtrabackup_history to 'backuper'@'localhost';

 

2、创建全备

innobackupex --user=backuper --password=123456 --host=127.0.0.1 --port=3306 /tmp/backup/

 

3、创建增备

innobackupex --user=backuper --password=123456 --host=127.0.0.1 --port=3306 --incremental --incremental-basedir=/tmp/backup/2016-09-07_04-14-17 /tmp/backup_incremental

 

4、在全备上前滚日志

innobackupex --apply-log --redo-only /tmp/backup/2016-09-07_04-14-17 

 

5、在增备上前滚&回滚日志

innobackupex --apply-log --incremental-dir=/tmp/backup_incremental/2016-09-07_04-22-36 /tmp/backup/2016-09-07_04-14-17 

 

6、把处于一致的备份复制到datadir目录下

innobackupex --defaults-file=/etc/my.cnf --copy-back /tmp/backup/2016-09-07_04-14-17 

 

7、调整数据的属主，属组 & 启动mysql服务

chown -R mysql:mysql /usr/local/mysql/data
service mysqld start

 

8、以single-file的方式来备份数据库

innobackupex --user=backuper --password=123456 --host=127.0.0.1 --port=3306 --stream=xbstream /tmp >/tmp/backup/mysql_3306_full.xbstream

 

9、把单文件解包成文件夹

xbstream -x < /tmp/backup/mysql_3306_full.xbstream -C /tmp/datadir

 

10、前滚&回滚日志

innobackupex --apply-log --use-memory=2G /tmp/datadir

 

11、把处于一致的备份复制到datadir目录下

innobackupex --defaults-file=/etc/my.cnf --copy-back /tmp/datadir
