There could be situations where we have to disable GTID in our replication setup.
We can follow below steps to do so. No need to change any GTID related parameters. We just have to change slave configuration and bounce slave. No need to touch master.

Step 1) Confirm that you are using GTID

If you check processlist on master, you can see GTID is enabled

master> show processlist \G
*************************** 1. row ***************************
     Id: 51
   User: replicate
   Host: master-1.db.example.com:43420
     db: NULL
Command: Binlog Dump GTID
   Time: 81316
  State: Master has sent all binlog to slave; waiting for binlog to be updated
   Info: NULL

Check the “command” above and it says “Binlog Dump GTID”

 

Step 2) Stop slave, reset master_auto_position to 0

mysql> stop slave;
Query OK, 0 rows affected (0.00 sec)

mysql> change master to master_auto_position=0;
Query OK, 0 rows affected (0.00 sec)

Step 3) Check slave status for master log file and position

mysql> show slave status \G
*************************** 1. row ***************************
               Slave_IO_State:
                  Master_Host: master-1.db.example.com
                  Master_User: replicate
                  Master_Port: 3306
                Connect_Retry: 5
              Master_Log_File: bin_log.000003
          Read_Master_Log_Pos: 191
               Relay_Log_File: relay_log.000001
                Relay_Log_Pos: 4
        Relay_Master_Log_File: bin_log.000003
             Slave_IO_Running: No
            Slave_SQL_Running: No
              Replicate_Do_DB:
          Replicate_Ignore_DB:
           Replicate_Do_Table:
       Replicate_Ignore_Table:
       ...
       ...
           Master_SSL_Crlpath:
           Retrieved_Gtid_Set:
            Executed_Gtid_Set: 8c593930-b4da-11e3-9e2d-b499ba05473c:1-7,
cc4192b6-a60d-11e4-8301-80c16e2272cc:1-168
                Auto_Position: 0
1 row in set (0.01 sec)

 

Step 4) Use change master to point to master log file and position

mysql> change master to master_host='master-1.db.example.com' , master_port = 3306 , master_user = 'replicate' , master_password='welcome' , master_log_file = 'bin_log.000003' , master_log_pos = 191, master_connect_retry = 5;
Query OK, 0 rows affected, 2 warnings (0.00 sec)

mysql> show warnings;
+-------+------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

| Note  | 1760 | Storing MySQL user name or password information in the master info repository is not secure and is therefore not recommended. Please consider using the USER and PASSWORD connection options for START SLAVE; see the 'START SLAVE Syntax' in the MySQL Manual for more information. |
+-------+------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

 

Step 5) start slave

mysql> start slave;
Query OK, 0 rows affected (0.00 sec)

show slave status will still show GTIDs but its not using GTIDs now

mysql> show slave status \G
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: master-1.db.example.com
                  Master_User: replicate
                  Master_Port: 3306
                Connect_Retry: 5
              Master_Log_File: bin_log.000003
          Read_Master_Log_Pos: 465
               Relay_Log_File: relay_log.000002
                Relay_Log_Pos: 586
        Relay_Master_Log_File: bin_log.000003
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
              Replicate_Do_DB:
              ...
              ...
     Last_SQL_Error_Timestamp:
               Master_SSL_Crl:
           Master_SSL_Crlpath:
           Retrieved_Gtid_Set: 8c593930-b4da-11e3-9e2d-b499ba05473c:8
            Executed_Gtid_Set: 8c593930-b4da-11e3-9e2d-b499ba05473c:1-8,
cc4192b6-a60d-11e4-8301-80c16e2272cc:1-168
                Auto_Position: 0
1 row in set (0.00 sec)

 

We can confirm that GTID is not getting used by checking processlist on master

master>show processlist \G
*************************** 1. row ***************************
     Id: 1
   User: root
   Host: localhost
     db: deo
Command: Query
   Time: 0
  State: init
   Info: show processlist
*************************** 2. row ***************************
     Id: 3
   User: replicate
   Host: master-1.db.example.com:59631
     db: NULL
Command: Binlog Dump
   Time: 24
  State: Master has sent all binlog to slave; waiting for binlog to be updated
   Info: NULL
2 rows in set (0.00 sec)

If you check “command” for row 2, you will notice GTID is gone.

Hope this helps !!
