xtrabackup的安装使用

一、安装percona-xtrabackup

yum安装

1、下载yum源

wget http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm
2、安装yum源

rpm -ivH percona-release-0.1-3.noarch.rpm

3、确认安装的包

yum list | grep percona

[root@mysql_test1 ~]# yum list | grep xtrabackup

percona-xtrabackup-24.x86_64 2.4.2-1.el6 @percona-release-x86_64

percona-xtrabackup.x86_64 2.3.4-1.el6 percona-release-x86_64

percona-xtrabackup-20.x86_64 2.0.8-587.rhel6 percona-release-x86_64

percona-xtrabackup-20-debuginfo.x86_64 2.0.8-587.rhel6 percona-release-x86_64

percona-xtrabackup-20-test.x86_64 2.0.8-587.rhel6 percona-release-x86_64

percona-xtrabackup-21.x86_64 2.1.9-746.rhel6 percona-release-x86_64

percona-xtrabackup-21-debuginfo.x86_64 2.1.9-746.rhel6 percona-release-x86_64

percona-xtrabackup-22.x86_64 2.2.13-1.el6 percona-release-x86_64

percona-xtrabackup-22-debuginfo.x86_64 2.2.13-1.el6 percona-release-x86_64

percona-xtrabackup-24-debuginfo.x86_64 2.4.2-1.el6 percona-release-x86_64

percona-xtrabackup-debuginfo.x86_64 2.3.4-1.el6 percona-release-x86_64

percona-xtrabackup-test.x86_64 2.3.4-1.el6 percona-release-x86_64

percona-xtrabackup-test-21.x86_64 2.1.9-746.rhel6 percona-release-x86_64

percona-xtrabackup-test-22.x86_64 2.2.13-1.el6 percona-release-x86_64

percona-xtrabackup-test-24.x86_64 2.4.2-1.el6 percona-release-x86_64

4、安装

yum install percona-xtrabackup-24

源码包安装，或者直接检查 find / -name 'libev.so*'

如果报错如下

LIBEV_INCLUDE_DIRS

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

Please set them or make sure they are set and tested correctly in the CMake files:

LIBEV_INCLUDE_DIRS (ADVANCED)

wget http://dist.schmorp.de/libev/libev-4.22.tar.gz
tar zxvf libev-4.22.tar.gz

cd libev-4.22

./configure

make && make install

[root@mysql_test2 libev-4.22]# find / -name 'libev.so*'

/usr/local/lib/libev.so.4

/usr/local/lib/libev.so.4.0.0

/usr/local/lib/libev.so

编译语句

cmake -DWITH_BOOST=/usr/local/boost/ -DBUILD_CONFIG=xtrabackup_release -DWITH_MAN_PAGES=OFF && make -j 10 && make install

[root@mysql_test2 bin]# pwd

/usr/local/xtrabackup/bin

[root@mysql_test2 bin]# ls

innobackupex xbcloud xbcloud_osenv xbcrypt xbstream xtrabackup

就可以使用innobackupex进行备份恢复了

5、查看位置

[root@mysql_test1 ~]# rpm -qa|grep xtrabackup

percona-xtrabackup-24-2.4.2-1.el6.x86_64

[root@mysql_test1 ~]# rpm -ql percona-xtrabackup-24-2.4.2-1.el6.x86_64

/usr/bin/innobackupex

/usr/bin/xbcloud

/usr/bin/xbcloud_osenv

/usr/bin/xbcrypt

/usr/bin/xbstream

/usr/bin/xtrabackup

/usr/share/doc/percona-xtrabackup-24-2.4.2

/usr/share/doc/percona-xtrabackup-24-2.4.2/COPYING

/usr/share/man/man1/innobackupex.1.gz

/usr/share/man/man1/xbcrypt.1.gz

/usr/share/man/man1/xbstream.1.gz

/usr/share/man/man1/xtrabackup.1.gz

二、使用xtrabackup

1、全备

/usr/bin/xtrabackup --defaults-file=/etc/my.cnf --user=root --password=123456 --port=38141 --backup

备份文件夹在当前目录的xtrabackup_backupfiles下

2、增量备份

/usr/bin/xtrabackup --defaults-file=/etc/my.cnf --user=root --password=123456 --port=38141 --backup --target-dir=/www/xtrabackup/20160425/ --incremental-basedir=/root/xtrabackup_backupfiles/

备注：--incremental-basedir=/root/xtrabackup_backupfiles/ 全备的路径

--incremental-basedir=/root/xtrabackup_backupfiles/ 增量备份的路径

3、还原

1、恢复全备

/usr/bin/xtrabackup --defaults-file=/etc/my.cnf --prepare --apply-log-only --target-dir=/root/xtrabackup_backupfiles/

2、恢复增量备份

/usr/bin/xtrabackup --defaults-file=/etc/my.cnf --prepare --apply-log-only --target-dir=/root/xtrabackup_backupfiles/ --incremental-dir=/www/xtrabackup/20160425/

3、拷贝回数据库目录

/usr/bin/xtrabackup --defaults-file=/etc/my.cnf --copy-back --target-dir=/root/xtrabackup_backupfiles

chown -R mysql.mysql /opt/mydata

查看恢复文件的备份还原信息

[root@mysql_test1 mydata]# more xtrabackup_binlog_pos_innodb

mysql-bin.000001 1703

全恢复+增量恢复到的日志点

[root@mysql_test1 mydata]# more xtrabackup_info
