Question

我在设置从属复制时遇到问题。两者都使用mysql 5.6并启用GTID。 Master位于rackspace的云数据库HA实例

上

我包含的转储上有一个GTID和主。

我通过将以下内容添加到从属设备上来启用GTID（我没有打开它）。然后我删除了所有数据库，因此它很新鲜。

gtid_mode=ON
enforce_gtid_consistency=true
log_bin=/Library/Application Support/appsolute/MAMP PRO/db/mysql56/log
log_slave_updates=true
binlog_format=mixed

我跑的命令：

mysqldump  --tz-utc=false -u root -pPASSWORD --host=HOST --all-databases > dump.sql

mysql>CHANGE MASTER TO MASTER_HOST = 'MASTER_HOST', MASTER_PORT = 3306, MASTER_USER = 'repl_user', MASTER_PASSWORD = 'PASSWORD', MASTER_AUTO_POSITION = 1;
mysql>reset master;
mysql>source dump.sql;
mysql>start slave;


mysql> show slave status \G

Answer 1

通常，这意味着主服务器和从服务器上的数据集不同。我们通常做的是使用xtrabackup创建二进制备份，将其传输到从属服务器，然后使用MASTER_AUTO_POSITION=1开始复制。在您的特定示例中， first 需要加载转储，然后执行CHANGE MASTER命令。

事实上，在与OP聊天后，他发现问题出在创建部分mysqldump，而不是转储所有信息。
