从阿里云mysqldump的sql文件导入本地库报错

[root@localhost ~]# mysql -uroot -p$(cat mysql_password.txt) xxx < /home/backup/xxx/xxx2020-05-07-04-00-01.sql 
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1840 (HY000) at line 24: @@GLOBAL.GTID_PURGED can only be set when @@GLOBAL.GTID_EXECUTED is empty.

原因是阿里云rds自带主从复制，开启了gtid全局事务id用于保证主从复制一致，备份的时候没有忽略gtid，导致导入本地时报错。

方法1、

# 查看当前的gtid
mysql> select @@global.gtid_executed\G;

# 清空本地的gtid
mysql> reset master;
Query OK, 0 rows affected (0.04 sec)

方法2、删掉sql文件中的 SET @@GLOBAL.GTID_PURGED 2行

-- GTID state at the beginning of the backup

SET @@GLOBAL.GTID_PURGED='6822560b-3659-11e8-afba-7cd30adaf22a:1-33310212,
79abd425-3659-11e8-8eeb-7cd30adaf28e:1-36989543';

方法3、

/usr/local/mysql/bin/mysqldump --set-gtid-purged=OFF
加上--set-gtid-purged=OFF参数再备份，这样就忽略。
