进行复制操作的用户会授予REPLICATION SLAVE权限。 # @后面的IP段,建议仅对从服务的网段进行开放CREATE USER 'artisan4syn'@'192.168.%.%' IDENTIFIED BY 'artisan';grant replication slave,replication client on *.* to artisan4syn@'192.168.%.%' identified by 'artisan';FLUSH PRIVILEGES; [root@artisan ~...
mysql_group_replication_hostgroups:该表用于MySQL Group Replication、InnoDB Cluster or Galera/Percona XtraDB Cluster的配置 因为我们这里是使用proxySQL来实现MGR集群业务层面的实现故障转移以及读写分离的,所以配置mysql_group_replication_hostgroups表即可,该表定义如下: showcreatetablemysql_group_replication_hostgroup...
接下来需要创建一个拥有从库权限的账号，用于订阅binlog，这里创建的账号为canal:canal；CREATE USER canal IDENTIFIED BY 'canal'; GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';FLUSH PRIVILEGES;创建好测试用的数据库canal-test，之后创建一张商品表product，建表语句如下。CREAT...
For this step-by-step tutorial, I’ve chosen Ubuntu Linux as the host operating system, and the provided commands are for that operating system. If you want to setup your MySQL master-slave replication on some other operating system, you will need to make modifications for its specific comman...
MySQL Replication是一个从Master复制到一台或多台Slave的异步复制过程。 Master和Slave之间实现整个复制过程主要由三个线程来完成,其中一个IO线程在Master端,两个线程(SQL线程和IO线程)在Slave端。 通过Master服务器打开Binary Log(二进制日志文件)的功能,Slave端从Master端获取该日志信息,然后将二进制文件解析为SQL语...

上图可以看到需要确认在确认前是否执行flush no_write_to_inlog tables 语句 这里输入YES 4.2 切换前确认 从上图可以看出,mha重新读取配置文件并确认数据库状态 这里确认是否需要从14.29切换至14.30 这里输入YES 4.3 切换阶段 之后就是正式的切换过程,简单概括如下 ...
