make sure File is "mysql-bin.000003" IF NOT RUN SQL ON SLAVE:

CHANGE MASTER TO MASTER_HOST='mysql-master', MASTER_USER='replica', MASTER_PASSWORD='duren123', MASTER_LOG_FILE='mysql-bin.000003', MASTER_LOG_POS=0;

Then restart slave

docker restart mysql-slave

Check slave status:

./status-slave.sh

make sure no error (Last_IO_Error and Last_SQL_Error)

Check master data:

docker exec -ti mysql-master mysql -u root --password=dodol123 xbrlgen

run sql:

SHOW TABLES;

make sure no table exists

Check slave data:

docker exec -ti mysql-slave mysql -u root --password=dodol123 xbrlgen

Run sql:

SHOW TABLES;

make sure no table exists

Run test sql on master:

docker exec -i mysql-master mysql -u root --password=dodol123 xbrlgen < test.sql

Check slave data:

docker exec -ti mysql-slave mysql -u root --password=dodol123 xbrlgen

Run sql:

SHOW TABLES;

make sure table DATA1 exists

SELECT * FROM DATA1;

make sure table DATA1 is not empty

Check replication status:

./status-master.sh

check the Position

./status-slave.sh

check Exec_Master_Log_Pos equal with

Switch master/slave

On slave:

STOP SLAVE;
RESET SLAVE ALL;

On master:
