GTID複製失敗錯誤1062

Question

我在設置從屬複製時遇到問題。兩者都使用mysql 5.6並啓用GTID。主站位於機架空間的雲數據庫HA實例

我包含的轉儲在它和主站上有一個GTID。

我啓用了GTID的奴隸通過添加以下內容到奴隸（我沒有它）。然後我刪除了所有的數據庫，所以它是新鮮的。

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

通常這意味着主站和從站的數據集不同。我們通常所做的就是創建一個xtrabackup的二進制備份，將其轉移到從屬設備，然後使用MASTER_AUTO_POSITION=1開始複製。在你的具體例子中你需要第一個加載轉儲，然後然後執行CHANGE MASTER命令。

事實上，在與OP交談後，他發現問題在於創建了部分mysqldump，而不是傾銷所有的信息。
