实战:percona-xtrabackup 2.1.9 for mysql 5.6.19

----1.编译安装percona-xtrabackup

yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bzr \

bison libtool ncurses-devel zlib-devel libgcrypt-devel

wget http://www.percona.com/downloads/XtraBackup/XtraBackup-2.1.9/source/percona-xtrabackup-2.1.9.tar.gz

tar xvzf percona-xtrabackup-2.1.9.tar.gz

mkdir -p /usr/local/xtrabackup/

mv percona-xtrabackup-2.1.9 /usr/local/xtrabackup/

cd /usr/local/xtrabackup/percona-xtrabackup-2.1.9

AUTO_DOWNLOAD="yes" ./utils/build.sh innodb56

/*****又一次安装须要

rm -rf /usr/bin/innobackupex

rm -rf /usr/bin/xtrabackup

***********/

cp innobackupex /usr/bin/

cp src/xtrabackup_56  /usr/bin/

ln -s /usr/local/mysql/bin/* /usr/bin/

---2.安装相关插件

wget http://www.percona.com/downloads/percona-toolkit/LATEST/RPM/percona-toolkit-2.2.8-1.noarch.rpm

yum install perl-DBI

yum install perl-DBD-MySQL

yum install perl-Time-HiRes

yum install perl-IO-Socket-SSL

rpm -ivh percona-toolkit-2.2.8-1.noarch.rpm

*****************************************************************

普通备份和还原

*****************************************************************

----1.备份

create table t1

(

sid int not null ,

sname varchar(100)  not null

)engine=innodb charset=gbk  ;

DELIMITER //

create PROCEDURE proc1()

BEGIN 

    DECLARE i int DEFAULT 0;

    set i=1 ;

set autocommit=0; 

WHILE i<=1000000 DO

INSERT INTO t1 values(i,'我');

set i=i+1;

END WHILE;

commit;

set autocommit=1;     

END 

//

DELIMITER ;

call proc1;

---2.备份数据

innobackupex  --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf \

--port=3306 /backup

---3.恢复数据

service mysql stop

mv /usr/local/mysql/data/innodb_data/  /wind/

或

cp -rvf innodb_data/  /wind/

----datadir数据文件夹和日志文件夹须要为空

rm -rf /usr/local/mysql/innodb_data/*

rm -rf /usr/local/mysql/data/*

rm -rf /usr/local/mysql/mysql_logs/innodb_log/*

----4.准备日志(默认使用内存100M)

 

innobackupex --ibbackup=xtrabackup_56    --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf  \

--apply-log  --use-memory=4G  /backup/2014-06-06_10-27-47

----5.还原数据库

innobackupex  --ibbackup=xtrabackup_56   --defaults-file=/usr/local/mysql/my.cnf   --copy-back /backup/2014-06-06_10-27-47

还原前数据文件和事务日志文件包含innodb的日志都须要删除.依据/et/my.cnf来确定MySQL的数据位置

---6.权限设置

chown -R mysql:mysql /usr/local/mysql/

service mysql start

*****************************************************************

增量备份和还原

*****************************************************************

----1.准备数据

create database wind;

use wind;

create table t1

(

sid int not null ,

sname varchar(100)  not null

)engine=innodb charset=gbk  ;

DELIMITER //

create PROCEDURE proc1()

BEGIN 

    DECLARE i int DEFAULT 0;

    set i=1 ;

set autocommit=0; 

WHILE i<=1000000 DO

INSERT INTO t1 values(i,'我');

set i=i+1;

END WHILE;

commit;

set autocommit=1;     

END 

//

DELIMITER ;

call proc1;

---2.全备数据

mkdir -p /backup/full

innobackupex  --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf \

--port=3306 /backup/full

----3.改变数据

create table t2

(

sid int not null ,

sname varchar(100)  not null

)engine=innodb charset=gbk  ;

DELIMITER //

create PROCEDURE proc2()

BEGIN 

    DECLARE i int DEFAULT 0;

    set i=1 ;

set autocommit=0; 

WHILE i<=2000000 DO

INSERT INTO t2 values(i,'今天是个好日子');

set i=i+1;

END WHILE;

commit;

set autocommit=1;     

END 

//

DELIMITER ;

call proc2;

----4.增量备份

mkdir -p /backup/incre

innobackupex  --use-memory=4G  --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf \

--port=3306  --incremental  /backup/incre   --incremental-basedir=/backup/full/2014-06-06_12-26-10

---3.恢复数据

service mysql stop

mv /usr/local/mysql/data/innodb_data/  /wind/

或

cp -rvf innodb_data/  /wind/

----datadir数据文件夹和日志文件夹须要为空

rm -rf /usr/local/mysql/innodb_data/*

rm -rf /usr/local/mysql/data/*

rm -rf /usr/local/mysql/mysql_logs/innodb_log/*

----4.准备日志(默认使用内存100M)

---4.1 Prepare完整备份集

/*语法:  innobackupex --apply-log --redo-only BASE-DIR  */

innobackupex --ibbackup=xtrabackup_56    --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf  \

--apply-log --redo-only   /backup/full/2014-06-06_12-26-10  --use-memory=4G

---4.2 Prepare增量备份集

/*语法:innobackupex --apply-log --redo-only BASE-DIR --incremental-dir= */

innobackupex --ibbackup=xtrabackup_56    --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf  \

--apply-log --redo-only   /backup/full/2014-06-06_12-26-10  --incremental-dir=/backup/incre/2014-06-06_12-38-16 \

--use-memory=4G

---4.3再次prepare全备集，回滚那些未提交的事务

/*语法: innobackupex --apply-log BASE-DIR */

innobackupex --ibbackup=xtrabackup_56    --user=root --password=password  --defaults-file=/usr/local/mysql/my.cnf  \

--apply-log    /backup/full/2014-06-06_12-26-10  --use-memory=4G

----5.还原数据库

innobackupex  --ibbackup=xtrabackup_56   --defaults-file=/usr/local/mysql/my.cnf \

--copy-back /backup/full/2014-06-06_12-26-10

chown -R mysql:mysql /usr/local/mysql/

---7.启动mysql

service mysql start
