使用 xtrabackup做mysql5.6.10主从

首先在master端安装xtrabackup

环境描述

测试服务器：（东莞机房、192.168.69.10、192.168.69.12）
master：192.168.69.10
slave： 192.168.69.12
mysql 5.6.10-log 二进制安装

主从库相关配置确认

（1）server-id配置
Master节点：

NDMC74:~ # mysql -S /tmp/mysql.sock -e "show global variables like 'server_id';"

+---------------+---------+

| Variable_name | Value |

+---------------+---------+

| server_id | 1 |

+---------------+---------+

Slaver节点：

NDMC75:~ # mysql -S /tmp/mysql.sock -e "show global variables like 'server_id';"

+---------------+---------+

| Variable_name | Value |

+---------------+---------+

| server_id | 2 |

+---------------+---------+

（2）确认binlog是否开启

NDMC74:~ # mysql -S /tmp/mysql.sock -e "show global variables like 'log_bin';"

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| log_bin | ON |

+---------------+-------+

Master上使用xtrabackup做全库备份

（注：--no-timestamp 参数，测试时不加该参数，报错无法进行）（在199.127上使用时加该参数会报错，灵活掌握)

Master上创建同步账号并授权REPLICATION

mysql> GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.69.12' IDENTIFIED BY 'replication';

Query OK, 0 rows affected (0.02 sec)
然后在Slave上测试，看看能否使用repl用户登录Master服务器：

将Master的全备scp到Slave主机上

[root@nginx-chinacache-dg-69-10 backup]# ll
总用量 4
drwxr-xr-x 6 root root 4096 6月 23 14:19 innobackupex
[root@nginx-chinacache-dg-69-10 backup]# tar -zcvf innobackupex.tgz ./innobackupex/
[root@nginx-chinacache-dg-69-10 backup]# scp -P 3609 innobackupex.tgz root@192.168.69.12:/tmp

将Slave上的MySQL停掉，然后将Master的备份文件放到Slave的datadir目录下：

[root@papp-chinacache-dg-69-12 ~]# mv /tmp/innobackupex.tgz /var/lib/
[root@papp-chinacache-dg-69-12 ~]# cd /var/lib/
[root@papp-chinacache-dg-69-12 ~]# mv mysql mysql.back
[root@papp-chinacache-dg-69-12 ~]# tar -zxvf innobackupex.tgz
[root@papp-chinacache-dg-69-12 ~]# mv innobackupex mysql
[root@papp-chinacache-dg-69-12 ~]# chown -R mysql:mysql data

注意：Slave的my.cnf文件和Master的一样，只是修改一下server-id即可。

启动Slave数据库

NDMC75:~ # /etc/init.d/mysqld start

同时查看一下error.log文件，看看有没有错误信息。

在slave上执行change master设置主服务器复制信息

Master binlog信息从备份文件中可以获得：

[root@nginx-chinacache-dg-69-10 innobackupex]# cat xtrabackup_binlog_info
mysqlmaster-bin.000001 986

设置slave参数
mysql> change master to master_host = '192.168.69.10',master_user='repl',master_password='replication',master_log_file='mysqlmaster-bin.000001',master_log_pos=986;

Query OK, 0 rows affected (0.05 sec)

在slave上启动复制

mysql> start slave;

Query OK, 0 rows affected (0.00 sec)

检查主从复制是否正常

mysql> show slave status\G
