MySQL数据库支持数据库的主从复制功能,因此在集群方面具有其独特的优势。众多国内外大型网站架构体系中,均采用了MySQL的主从数据库配置来实现查询负载、数据库热备等功能。本人在实际的Web项目中也涉及到这一需求,在此将如何配置实现做个简单小结。
本次环境:虚拟机下
服务器:Ubuntu 14.04 LTS
数据库: 5.5.37
端口:3306
主IP:192.168.63.133
从IP:192.168.63.134
授权账号:
user:suxh
password:111111
好了交代完环境:我们直接配置:
第一步:主从两台服务器要有同样的数据库(需要同步的)这里用的是backup 数据库(不多说了,(www.jbxue.com)在同步开始前,把主库的复制一份到从库就行了)
第二步配置主(master)数据库 编辑/etc/my.cnf 主要是开启二进制日志 和设置要同步的数据库 等一些参数
# binary logging format - mixed recommendedbinlog_format=mixedbinlog-ignore-db=mysqlbinlog-do-db=backup# required unique id between 1 and 2^32 - 1# defaults to 1 if master-host is not set# but will not function as a master if omittedserver-id = 1
参数解释下:
server-id 这个是唯一的不能跟从服务器相同。
binlog_format 二进制文件的格式
binlog_ignore-db 忽略的数据库
binlog-do-db 要同步的数据库
设置完了以后 重启数据库就可以了。
第三步从数据库:
同样修改/etc/my.cnf 在mysql 版本5.1.7 不支持master-host”类似的参数; 所以这里只要配置server-id=2 就可以了
然后登陆从数据库设置
change master to master_host='192.168.63.133', master_user='suxh', master_password='111111';
slave start;
