----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

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

----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
