1. Use mysqlpump to copy master data to slave, and build master-slave replication based on GTID. Lack of GTID processing method, it is not successful for the time being.

/ home/dbname.sql.gz

Common error: mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table.

Network write timed out, change net_write_timeout to 600, default is 60.

CHANGE MASTER TO

MASTER_HOST = 'host_name'

MASTER_USER = 'user_name'

MASTER_PASSWORD = 'password'

MASTER_AUTO_POSITION = 1

Start slave

3. Use mysqldbcompare for data consistency verification

Compare all databases with the same name between two servers

Ignore the following databases: INFORMATION_SCHEMA, PERFORMANCE_SCHEMA, mysql, and sys.

Mysqldbcompare-server1=user:password@localhost-server2=user:password@localhost-changes-for=server1-a

Databases are consistent. The check passed.

Complete the master-slave construction.
