记录一个比较简便的mysql的主从同步设置步骤,方便日后使用。

安装环境
centos 5.4
mysql 5.1.xx 采用rpm直接安装
xtrabackup 1.2.22 采用rpm直接安装
1. Master:/etc/my.cnf
[mysqld] server-id = 1 log-bin innodb_flush_log_at_trx_commit=1 sync_binlog=1 datadir=/var/lib/mysql character-set-server=utf8 init_connect='SET NAMES utf8'设定了默认字符集为utf8,可以按实际情况取舍这段配置。

2. Slave:/etc/my.cnf
[mysqld] server-id=2 datadir=/var/lib/mysql character-set-server=utf8 init_connect='SET NAMES utf8'

3. Master:在master数据库设置用来同步的slave用户权限
GRANT REPLICATION SLAVE ON *.* TO ''@'' IDENTIFIED BY '';

4. Master:导出数据到slave
采用xtrabackup来备份mysql,好处是在master的锁表时间很短,在实际的生产环境也可以使用,并且xtrabackup会自动记录同步日志文件的位置。

sudo innobackupex-1.5.1 --stream=tar /tmp/ | ssh "mkdir /tmp/db; tar xfi - -C /tmp/db/"这个步骤会把master的数据包括表结构整个导出并压缩复制给slave,同时解压到slave的/tmp/db目录下。

5. Slave:导入数据到slave
innobackupex-1.5.1 --apply-log /tmp/db innobackupex-1.5.1 --copy-back /tmp/db chown -R mysql.mysql /var/lib/mysql/*

6. Slave:开始同步数据
查看/var/lib/mysql/xtrabackup_binlog_info,获得日志文件以及position。

CHANGE MASTER TO MASTER_HOST='', MASTER_USER='', MASTER_PASSWORD='', MASTER_LOG_FILE='', MASTER_LOG_POS=; START SLAVE;
