一.GTID innobackupex备份实现主从同步 1)master备份 innobackupex --defaults-file=/etc/my.cnf --user=root --password=123456 --parallel=4 /backup 2)拷贝到slave上,并prepare和copy backup innobackupex --defaults-file=/etc/my.cnf --apply-log --user=root --password=123456 --p…
[问题二] 有一个集群(MySQL5.7.23)切换后复制slave报1236,其实是不小心在slave上执行了事务导致 Got fatal error 1236 from master when reading data from binary log: 'The slave is connecting using CHANGE MASTER TO MASTER_AUTO_POSITION = 1, but the master has purged binary logs containin…

基于GTID的复制 简介 基于GTID的复制是MySQL 5.6后新增的复制方式. GTID (global transaction identifier) 即全局事务ID, 保证了在每个在主库上提交的事务在集群中有一个唯一的ID. 在原来基于日志的复制中, 从库需要告知主库要从哪个偏移量进行增量同步, 如果指定错误会造成数据的遗漏, 从而造成数据的不一致. 而基于GTID的复制中, 从库会告知主库已经执行的事务的GTID的值, 然后主库会将所有未执行的事务的GTID的列表返回给从库. 并且可以…

一 GITD介绍 1.1 gtid的含义 Global Transaction Identifier,全局事务标识 阿里云的rds目前已经使用gtid 基于gtid的主从复制原理 每个mysql数据库上都有一个唯一uuid 每个事务生成一个id gtid由上面两者组合: uuid+事务id 1.2 优势 相对使用binlog+位置的方法来说 gtid让配置主从更加方便 从提升为主时比较方便 二 配置 2.1 主库的配置 [mysqld] bind-address=0.0.0.0 port= da…

        since i've broken down the replication enviornment by "reset master;" yesterday.therefore,i'd like to reconfigure it again,there're several simple steps below:   I. Master node operations: .Check the necessary parameter is surely spedifi…
