----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


/*****重新安装需要
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数据目录和日志目录需要为空

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括innodb的日志都需要删除.根据/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数据目录和日志目录需要为空

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

---6.权限设置

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

 

---7.启动mysql

service mysql start
