mysql 5.7 多源复制 原创

my.cnf要加两个参数才可以在GTID多源复制
master-info-repository=TABLE

server1 连到 slave1 

mysql> change master to master_host=‘10.24.220.70‘,master_user=‘repl‘,master_password=‘123‘,master_port=3306,master_auto_position=1 for channel ‘slave1‘;
server1 连到 slave2 

mysql> change master to master_host=‘10.169.214.33‘,master_user=‘repl‘,master_password=‘123‘,master_port=3307,master_auto_position=1 for channel ‘slave2‘;
server1:mysql> start slave;    //两个通道一起起动了

mysql 5.7 多源复制 原创的相关文章

mysql 5.7多源复制(用于生产库多主库合并到一个查询从库)

目前我们使用的是主从+分库分表的系统架构,主库有N个分库,从库为多个slave做负载均衡,所以数据库端的架构是下面这样的: 这就涉及到多个主库数据同步到不分库分表的从库共查询和管理类系统使用.在mysql 5.6以及之前的版本中,没有原生的解决方法,除非使用mariadb分支,在mysql 5.7之后支持多源复制,除了使用原生的多源复制之外,还有一个选择,就是使用案例开源的otter/canal.如果只是N个库合并到一个库的,我们使用mysql原生的复制,因为无论从稳定性还是运维成本.系统要求的

MySQL 5.7的多源复制

MySQL 5.7已经开始支持了多源复制,相信小伙们都很激动,MySQL 5.7之前只能实现一主一从.一主多从或者多主多从的复制,如果想实现多主一从的复制,只好使用MariaDB,但是MariaDB又与官方的MySQL版本不兼容的,在MySQL 5.7版本已经可以实现多主一从的复制了.MySQL 5.7版本相比之前的版本,无论在功能还是性能.安全等方面都已经提升了不少,值得大家去研究和使用. MySQL 5.7版本之前的最常见的复制方式,一主一从或者一主多从的架构: MySQL 5.7之后就可以

基于GTID的MySQL多源复制配置

多源复制的意义 1.可以在一个从库上对多个服务器的数据库进行汇总,或者对一个数据库的分库分表进行汇总. 2.集约使用从库服务器的硬件资源,毕竟弱一个数据库业务量较小确占用整个服务器资源是不经济的. 3.更方便的对个业务库进行数据备份,优化数据库备份脚本编写逻辑 拓补图 实施步骤 1.备份主库上的数据,考虑到gtid的问题建议只采用mysqldump程序进行备份 centos:#mysqldump --login-path=3306 \ #mysql官方工具都支持login-path快速登录

mysql多源复制详解

大家应该知道,mysql比起其他数据库,最大的特色是就是主从复制,不过5.7之前的版本最多就只支持一主多从的复制方式,对于一些统计类的需求,就需要跨库,这是比较麻烦的事情,以往只能交由数据库中间件(mycat等)去做这种事情,还有备份操作,也只能一个个库的用脚本去轮询或并发备份,不可谓不费时费力.然后,多源复制的概念出来了. 多源复制的概念最早是mariadb社区提出的,后来mysql官方积极引入到5.7的版本中来(5.6最新版也是没有这个功能的),percona就不说了,也是随后推出.这个功能
