mysql xtrabackup在windows平台的备份测试是怎么样的，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。 Xtrabackup有2款主要工具：xtrabackup和innobackupex xtrabackup只能备份和恢复innodb，而且只备份.ibd文件，.frm文件它不管，恢复时DBA要自己提供 innobackupex能备份和恢复MyISAM文件及.frm文件，并且对xtrabackup作了友好的封装，所以可用它进行全库备份 下载完解压缩到C盘xtrabackup目录下,发现共有4个文件,xtrabackup.exe是可执行文件 C:\xtrabackup>dir 驱动器 C 中的卷是 Windows8_OS 卷的序列号是 0E54-579B C:\xtrabackup 的目录 2016/06/03 09:42 . 2016/06/03 09:42 .. 2009/12/08 14:37 6,656 cat.exe 2003/10/23 17:35 135,680 grep.exe 2011/04/21 15:23 90,876 innobackupex.pl 2011/04/20 11:39 4,863,488 xtrabackup.exe 这里我们用xtrabackup命令进行innodb全库备份测试: xtrabackup命令的用法: Usage: [C:\xtrabackup\xtrabackup [--defaults-file=#] --backup | C:\xtrabackup\xtrabackup [--defaults-file=#] --prepare] [OPTIONS] 建立innodb测试库: mysql> create database duansf; Query OK, 1 row affected (0.17 sec) mysql> use duansf Database changed mysql> mysql> mysql> mysql> mysql> create table dsf(id int); Query OK, 0 rows affected (0.37 sec) mysql> insert into dsf values(1); Query OK, 1 row affected (0.11 sec) mysql> insert into dsf values(2); Query OK, 1 row affected (0.14 sec) mysql> insert into dsf values(3); Query OK, 1 row affected (0.06 sec) mysql> insert into dsf values(4); Query OK, 1 row affected (0.17 sec) mysql> insert into dsf values(5); Query OK, 1 row affected (0.09 sec) mysql> select * from dsf; +------+ | id | +------+ | 1 | | 2 | | 3 | | 4 | | 5 | +------+ 5 rows in set (0.03 sec) mysql> 查看数据文件所在目录: mysql> show variables like 'datadir'; +---------------+---------------------------------------------+ | Variable_name | Value | +---------------+---------------------------------------------+ | datadir | C:\ProgramData\MySQL\MySQL Server 5.5\Data\ | +---------------+---------------------------------------------+ 1 row in set (0.00 sec) mysql> 完全备份: C:\xtrabackup\xtrabackup --target-dir=C:\xtrabackup\full --backup --datadir="C:\ProgramData\MySQL\MySQL Server 5.5\Data\" c:\xtrabackup>C:\xtrabackup\xtrabackup --target-dir=C:\xtrabackup\full --backup --datadir="C:\ProgramData\MySQL\MySQL Server 5.5\Data\duansf" C:\xtrabackup\xtrabackup Ver undefined Rev undefined for 5.5.9 Win64 (x86) xtrabackup: cd to C:\ProgramData\MySQL\MySQL Server 5.5\Data\duansf xtrabackup: Target instance is assumed as followings. xtrabackup: innodb_data_home_dir = .\ xtrabackup: innodb_data_file_path = ibdata1:10M:autoextend xtrabackup: innodb_log_group_home_dir = .\ xtrabackup: innodb_log_files_in_group = 2 xtrabackup: innodb_log_file_size = 5242880 InnoDB: The first specified data file .\ibdata1 did not exist: InnoDB: a new database to be created! 160603 10:32:56 InnoDB: Setting file .\ibdata1 size to 10 MB InnoDB: Database physically writes the file full: wait... xtrabackup: Something wrong with source files... 发现有报错，后来研究了一下，把C:\Program Files (x86)\MySQL\MySQL Server 5.5\my.ini拷贝到c:\xtrabackup目录下再执行以下命令后测试通过: c:\xtrabackup>xtrabackup.exe --defaults-file=C:\xtrabackup\my.ini --backup --target-dir=C:\xtrabackup\full xtrabackup.exe Ver undefined Rev undefined for 5.5.9 Win64 (x86) xtrabackup: cd to C:/ProgramData/MySQL/MySQL Server 5.5/Data/ xtrabackup: Target instance is assumed as followings. xtrabackup: innodb_data_home_dir = .\ xtrabackup: innodb_data_file_path = ibdata1:10M:autoextend xtrabackup: innodb_log_group_home_dir = .\ xtrabackup: innodb_log_files_in_group = 2 xtrabackup: innodb_log_file_size = 118489088 >> log scanned up to (1625547) [01] Copying .\ibdata1 to C:\xtrabackup\full/ibdata1 [01] ...done xtrabackup: The latest check point (for incremental): '1625547' xtrabackup: Stopping log copying thread..>> log scanned up to (1625547) xtrabackup: Transaction log of lsn (1625547) to (1625547) was copied. 注意:如果重复执行xtrabackup命令执行备份就会报错，我猜测这可能是由于xtrabackup在windows平台只是个测试版，没有发布正式版，因此 生产环境还是慎用windows平台版本。 （编辑：银川站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
