GTID复制失败错误1062

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。主站位于机架空间的云数据库HA实例

我包含的转储在它和主站上有一个GTID。

我启用了GTID的奴隶通过添加以下内容到奴隶（我没有它）。然后我删除了所有的数据库，所以它是新鲜的。

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 

命令我跑：

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

通常这意味着主站和从站的数据集不同。我们通常所做的就是创建一个xtrabackup的二进制备份，将其转移到从属设备，然后使用MASTER_AUTO_POSITION=1开始复制。在你的具体例子中你需要第一个加载转储，然后然后执行CHANGE MASTER命令。

事实上，在与OP交谈后，他发现问题在于创建了部分mysqldump，而不是倾销所有的信息。
