Innobackup mysql 多实例环境搭建主从同步

该实验是在mysql多实例环境下做的;如果需要部署 mysql 多实例环境,则移步:


mysql 的主从搭建大家有很多种方式,传统的 mysqldump 方式是很多人的选择之一。但对于较大的数据库则该方式并非理想的选择。使用 Xtrabackup 可以快速轻松的构建 mysql 主从架构。本文描述了使用innobackupex快速来搭建主从架构。

需求:

(1)用户通过 innobackupex 从 mysql-master备份数据
(2)将主库备份的数据在 mysql-slave 还原数据
(3)设置 mysql-master 和 mysql-slave 数据实时同步

mysql多实例化 mysql单实例多库_mysql多实例化

环境:
mysql-master:10.1.0.50
mysql-slave:10.1.0.60
mysql 版本:5.6.14

准备:
percona-xtrabackup 安装包,提供 innobackupex 工具

下面开始:

一、安装 percona-xtrabackup(主从都需要,主用来备份,从用来还原)

下载地址:http://www.percona.com/downloads/XtraBackup/

[root@master ~]# yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL libev-devel
[root@master ~]# rpm -ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm


二、主库备份数据(mysql-master:10.1.0.50)

[root@master ~]# mkdir /tmp/backup
[root@master ~]# time innobackupex –defaults-file=/etc/my.cnf –defaults-group=mysqld1 –user=root –password=$(cat /data/save/mysql_root) –socket=/tmp/mysql3306.sock /tmp/backup/


二、打包,传递到从库(mysql-slave:10.1.0.60)

[root@master tmp]# tar zcf backup.tgz backup/
[root@master tmp]# scp backup.tgz 10.1.0.60:/tmp


三、还原从主库备份的数据

解包:
[root@slave tmp]# tar zxf backup.tgz

停止数据库,备份旧的数据目录,并且新建一个数据目录,进行还原从主库备份的数据:
[root@slave data]# /usr/local/mysql/bin/mysqld_multi stop 1
[root@slave tmp]# mv /usr/local/mysql/data/dbdata_3306/ /usr/local/mysql/data/dbdata_3306_bak
[root@slave tmp]# mkdir -p /usr/local/mysql/data/dbdata_3306

还原数据:
[root@slave data]# time innobackupex –defaults-file=/etc/my.cnf –defaults-group=mysqld1 –user=root –password=$(cat /data/save/mysql_root) –apply-log /tmp/backup/2016-04-19_16-57-37/

[root@slave data]# time innobackupex –defaults-file=/etc/my.cnf –defaults-group=mysqld1 –user=root –password=$(cat /data/save/mysql_root) –copy-back /tmp/backup/2016-04-19_16-57-37/

注意:
–apply-log 选项的命令是准备在一个备份上启动mysql服务
–copy-back 选项的命令从备份目录拷贝数据,索引,日志到my.cnf文件里规定的初始位置

授权,并且启动 mysql 服务:
[root@slave data]# chown mysql:mysql -R /usr/local/mysql/data/dbdata_3306/
[root@slave data]# /usr/local/mysql/bin/mysqld_multi start 1


四、从库设置并启动主从同步

我们先来看看 innobackupex 备份后生成的一份文件,里面记载了主从所需要的 MASTER_LOG_FILE 和 MASTER_LOG_POS

mysql多实例化 mysql单实例多库_innobackup_02

登录数据库

mysql多实例化 mysql单实例多库_innobackup_03

输入 mysql-master 的 user,host,port,password,log_file,log_pos 等信息,接着启动主从命令:start slave;

查看主从情况(发现是正常的):
