meb文件用什么打开,meb文件哪里找

一、 环境摘要1.1 NBU备份MySQL方案概述

NetBackup可采用以下几种方案对MySQL进行备份:

ü 关闭mysql并以文件形式离线备份(无法做到热备份)

ü 采用脚本或工具(如mysqldump)将MySQL数据先导出到文件系统然后再通过NBU对其备份

ü 采用Zmanda代理或MySQL Enterprise Backup与NetBackup结合使用

补充说明:

Ø 自带的mysqldump备份恢复速度慢(只要是逻辑备份数据量较大均不推荐),备份出来的为sql语句(即DDL insert),增备利用mysql binlog,必须开启二进制日志

Ø NetBackup 8.1之前版本并无MySQL Agent,NBU Agent从8.1才开始引入,是通过创建快照来进行MySQL备份(适用于Windows的卷影复制服务(VSS)或Linux的逻辑卷管理器(LVM)须可获取数据库快照)

注:NetBackup for MySQL Agent支持完全备份、完全恢复以及重定向恢复(即异机恢复),不支持增量备份恢复、表级备份恢复。

Ø Zmanda或MEB对MySQL进行按需(全备、增备等)备份,NetBackup提供备份介质和策略管理(作业调度计划、保留周期等),NBU与其结合将MySQL直接备份至指定介质(如磁盘、磁带等)

Ø Zmanda已从开源转向Enterprise且使用率较低,配置麻烦因此不再考虑使用

Ø MySQL Enterprise Backup 3.6版本开始支持与介质管理软件(MMS)(如Symantec NetBackup,ORACLE Secure Backup(OSB),IBM Tivoli Storage Manager(TSM))连接,以通过系统备份到磁带(SBT)接口执行备份和还原操作。SBT是作为共享库(Linux中的libobk.so和Windows中的orasbt.dll)实现的Oracle API,用于通过第三方软件供应商备份/恢复数据,MEB可通过MetaLink下载正常使用但属于商业软件(本次仅用于测试)

注:以上数据仅供参考,表格中所有工具并未全部测试,数据来源于网络

备注:XtraBackup 是一款可免费使用的开源工具,功能、使用率及备份速度均不错(与MEB难分伯仲),但此工具仅备份至文件系统或其他服务器,无法直接通过NetBackup lib库(libobk.so)结合将数据备份至NBU备份介质。

1.3 测试环境简述

本次测试采用NetBackup 7.7.3 Linux Server通过MEB(MySQL Enterprise Backup)对MySQL 5.6和5.7分别进行备份恢复操作(采用LAN备份),备份拓扑如下图所示:

说明(经验值,需根据具体环境而定):

Ø 数据量小于500GB可优先考虑采用LAN模式备份(部署相对简单方便且Standard Client无需访问备份介质)

Ø 数据量大于500GB可考虑采用LAN_FREE模式备份(需Enterprise Client且可访问备份介质)

Ø 数据量小于2TB可考虑每日完全备份,大于2TB考虑每周1-2次全备 增备组合方式

Ø 在备份数据量较大、保留周期较长、备份频率较高等环境中若后端备份介质支持压缩、去重功能可节省大量空间

二、 参数核查

1

2.1 系统版本检查

cat /etc/redhat-release

CentOS release 6.10 (Final)

2.2 MySQL版本检查

以下几种方法任选其一即可:

方法一:用户登录后便可看到版本信息

方法二:通过status命令查看

方法三:通过select命令查看

方法四:通过mysql --help命令查看

方法五:通过rpm –qa命令查看

2.3 MySQL其他参数查看

1、 查看port:

mysql> show global variables like 'port';

2、 查看datadir:

mysql> show global variables like "?tadir%";

三、创建用户并赋权

备份需要MySQL特定用户连接到MySQL服务器,因此需要单独创建备份用户并赋权(亦可使用如root等管理账户操作)。

注:请根据之前核查的MySQL版本对应选择:

3.1 MySQL 5.7.21 and later

CREATE USER 'mysqlbkuser'@'localhost' IDENTIFIED BY 'P@ssw0rd';

GRANT RELOAD ON *.* TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_progress TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,DROP,UPDATE,SELECT,ALTER ON mysql.backup_history TO 'mysqlbkuser'@'localhost';

GRANT REPLICATION CLIENT ON *.* TO 'mysqlbkuser'@'localhost';

GRANT SUPER ON *.* TO 'mysqlbkuser'@'localhost';

GRANT PROCESS ON *.* TO 'mysqlbkuser'@'localhost';

GRANT SELECT ON performance_schema.replication_group_members TO 'mysqlbkuser'@'localhost';

备1:For using transportable tablespaces (TTS) to back up and restore InnoDB tables还须赋予以下权限,否则跳过:

GRANT LOCK TABLES,ALTER,SELECT,CREATE,DROP,FILE ON *.* TO 'mysqlbkuser'@'localhost';

备2:For creating tape backups using the System Backup to Tape (SBT) API还须赋予以下权限,否则跳过:

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_sbt_history TO 'mysqlbkuser'@'localhost';

3.2 MySQL 5.7.9 to 5.7.20

CREATE USER 'mysqlbkuser'@'localhost' IDENTIFIED BY 'P@ssw0rd';

GRANT RELOAD ON *.* TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_progress TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,SELECT,DROP,UPDATE ON mysql.backup_history TO 'mysqlbkuser'@'localhost';

GRANT REPLICATION CLIENT ON *.* TO 'mysqlbkuser'@'localhost';

GRANT SUPER ON *.* TO 'mysqlbkuser'@'localhost';

GRANT PROCESS ON *.* TO 'mysqlbkuser'@'localhost';

备1:For using transportable tablespaces (TTS) to back up and restore InnoDB tables还须赋予以下权限,否则跳过:

GRANT LOCK TABLES,ALTER,SELECT,CREATE,DROP,FILE ON *.* TO 'mysqlbkuser'@'localhost';

备2:For creating tape backups using the System Backup to Tape (SBT) API还须赋予以下权限,否则跳过:

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_sbt_history TO 'mysqlbkuser'@'localhost';

3.3 MySQL 5.7.9 earlier and 5.6

CREATE USER 'mysqlbkuser'@'localhost' IDENTIFIED BY 'P@ssw0rd';

GRANT RELOAD ON *.* TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_progress TO 'mysqlbkuser'@'localhost';

GRANT CREATE,INSERT,SELECT,DROP,UPDATE ON mysql.backup_history TO 'mysqlbkuser'@'localhost';

GRANT REPLICATION CLIENT ON *.* TO 'mysqlbkuser'@'localhost';

GRANT SUPER ON *.* TO 'mysqlbkuser'@'localhost';

备1:For using transportable tablespaces (TTS) to back up and restore InnoDB tables还须赋予以下权限,否则跳过:

GRANT LOCK TABLES,ALTER,SELECT,CREATE,DROP,FILE ON *.* TO 'mysqlbkuser'@'localhost';

备2:For creating tape backups using the System Backup to Tape (SBT) API还须赋予以下权限,否则跳过:

GRANT CREATE,INSERT,DROP,UPDATE ON mysql.backup_sbt_history TO 'mysqlbkuser'@'localhost';

四、 创建备份脚本

使用《Create_NBU_scripts_V1.2.sh》可快速规范创建NBU备份MySQL或ORACLE脚本,提高效率并降低出错率,具体步骤如下:

1、 将脚本上传至客户端任意目录并赋权:

chmod x Create_NBU_Scripts_V1.2.sh

2、 运行脚本并输入相关信息(根据提示输入需要的信息即可),如下所示:

[root@backup tmp]# ./Create_NBU_Scripts_V1.2.sh

Create NetBackup Script, Do you wish to continue? [y,n] (y)

Choose the Backup Type you wish to create

1) NetBackup Script for MySQL DataBase(Use MEB)

2) NetBackup Script for Oracle DataBase

3) NetBackup Script for Oracle ArchiveLog

4) NetBackup Script for Oracle DataBase and ArchiveLog

x) Exit from this Script

Choose an option: 1

Input script directory and name: (default: /usr/openv/scripts)

Input MySQL port number: (default: 3306)

Input MySQL user name: (default: mysqlbkuser)

Input MySQL User mysqlbkuser's password: (default: P@ssw0rd)

Input MySQL IP address: (default: 127.0.0.1)

Input MySQL the directory to store the backup data: (default: /mysqlbak_nbu)

"/mysqlbak_nbu" directory does not exist, create the directory? [y,n] (y)

Input script name: (default: hot_mysql.sh)

Input MEB mysqlbackup file path: (/opt/mysql/meb-3.12/bin/mysqlbackup)

"/usr/openv/scripts/hot_mysql.sh" has been created.

This script can be deleted after you are sure the create was successful.

3、 完成后的脚本信息如下所示:

#!/bin/sh

4、 附件(脚本)如下:

五、 创建备份策略

1、 创建一个新策略并输入策略名称:

2、 “Attributes”选项卡中修改Policy type为“Oracle”并设置好Policy storage和Policy volume pool:

3、 “Clients”选项卡中修改为“Clients for use with scripts or templates”并添加客户端名称(须可解析)或IP地址:

4、 “Backup Selections”选项卡中选择并添加之前创建好的备份脚本:

5、 “Schedules”选项卡中添加调度策略并设置保留周期:

六、 手工发起备份测试

1、 右键单击之前创建好的策略并选择“Manual Backup…”:

2、 选择全备:

3、 此时在“Activity Monitor”界面中可看到备份作业已在运行中:

4、 等待备份完成后在之前的脚本所在目录中可生成备份作业日志:

5、 可查看此out文件查看备份情况以及后期排故:

七、 全备恢复测试

恢复主要分三大步:restore、apply-log、copy-back

1、 第一步:restore

/opt/mysql/meb-4.1/bin/mysqlbackup --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64 --backup-dir=/mysql_restore --backup-image=sbt:FULL_bkpsbtNB_180804003931 image-to-backup-dir

2、 第二步:apply-log

/opt/mysql/meb-4.1/bin/mysqlbackup --backup-dir=/mysql_restore apply-log

3、 第三步:copy-back

拷贝前先关闭数据库或停止mysqld服务

mysqladmin -u root -p shutdown service mysqld stop

/opt/mysql/meb-4.1/bin/mysqlbackup --backup-dir=/mysql_restore copy-back --force

注:若原有datadir目录存在且不为空则会报错,删除原有文件或使用--force选项

180804 01:47:10 MAIN ERROR: The datadir exists and is not empty. Use the "--force" option, if you want to overwrite the datadir on your own risk.

说明:以上分步操作亦可使用“copy-back-and-apply-log”参数一步完成:

1、 关闭数据库或停止mysqld服务:mysqladmin -u root -p shutdown

2、 恢复操作:

/opt/mysql/meb-3.12/bin/mysqlbackup --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64 --datadir=/var/lib/mysql/ --backup-dir=/mysql_restore --backup-image=sbt:FULL_bkpsbtNB_180807113438 copy-back-and-apply-log --force

注1:--datadir参数是否必须根据MEB版本有所不同

注2:恢复完成后mysqld服务若无法正常启动首先确认数据文件用户及所属组属性设置是否正确(通过chown mysql:mysql xxx 修改)

3、 命令运行后会在NBU JAVA CONSOLE的“Activity Monitor”界面中看到恢复作业已在运行中:

4、 恢复输出仅供参考:

4、 登录数据库并进行数据校验、业务测试等。

九、 使用TTS备份9.1 TTS选项简介

若后期需要从备份中恢复某些表(即表级别恢复),那么在备份时必须要以transportable tablespaces (TTS) 方式备份,否则无法仅恢复指定表。

transportable tablespaces (TTS) 主要使用两个参数( --include-tables 和 --exclude-tables)来指定或排除表(后面值可使用正则表达式),运行机制是先执行include-tables后在执行exclude-tables,两个参数可同时使用。

例1:备份所有数据库中的所有表:

--include-tables="." 或 --include-tables=".*"

例2:备份test数据库中的所有表:

--include-tables="test\."

例3:备份“test”数据库中的所有表,但不包括名称为“test2”的表:

--include-tables="test\." --exclude-tables="test\.test2"

9.2 使用TTS选项备份

本次测试采用TTS选项多所有数据库中所有表进行备份操作:

备注:执行命令后在NBU JAVA CONSOLE中“Activity Monitor”页面会有作业生成且为Active状态

十、 使用TTS恢复10.1 必要条件

使用—use-tts选项恢复时需注意:

ü MySQL Server须处于运行状态

ü 目标端须使用相同的page size

ü innodb_file_per_table选项须开启(值=ON)

ü 需要恢复的表在目标端不存在

ü MEB各版本稍有不同,4.0之前版本必须指定—datadir参数

10.2 删除源表恢复

1、 在test数据库中删除test表进行恢复操作:

mysql> use test;

mysql> drop table test;

2、 恢复test数据库中的test表:

10.3 重命名恢复

在恢复时亦可使用“--rename”选项对指定表进行重命名

可以使用完全限定表明:源数据库名.源表名 to 新数据库名.新表名

若在同一个数据库中重命名表则可不使用完全限定:源表名 to 新表名

1、 恢复test数据库中的test表并重命名为test2:
