MySQL的企业备份（MEB）
一、安装
[root@gflinux meb]# ll
total 2936
-rw-r--r-- 1 root root 2998307 Jan 30 16:02 V59673-01.zip
[root@gflinux meb]# unzip V59673-01.zip
Archive: V59673-01.zip
extracting: meb-3.11.1-rhel5.i386.rpm
extracting: README.txt
[root@gflinux meb]# rpm -ivh meb-3.11.1-rhel5.i386.rpm
[root@gflinux meb]# find / -name mysqlbackup
/opt/mysql/meb-3.11/bin/mysqlbackup
[root@gflinux meb]# cp /opt/mysql/meb-3.11/bin/mysqlbackup /usr/bin/
二、创建备份账号并赋予特权
为了使特权用户能够利用MEB进行备份，就需要提高访问权限，这些特权包括：
mysql> CREATE USER dbbackup@localhost IDENTIFIED BY ‘123456‘;
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT RELOAD,REPLICATION CLIENT,SUPER,CREATE TEMPORARY TABLES ON *.* TO ‘dbbackup‘@‘localhost‘;
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT CREATE,INSERT,DROP ON mysql.backup_progress TO ‘dbbackup‘@‘localhost‘;
Query OK, 0 rows affected (0.01 sec)
mysql> GRANT CREATE,INSERT,DROP ON mysql.backup_history TO ‘dbbackup‘@‘localhost‘;
Query OK, 0 rows affected (0.00 sec)
三、备份
