1. Modify my.cnf on the master to set a server-id and use bin logging 

   Code Block
   [mysqld] log-bin=mysql-bin binlog_format=row server-id=1

2. Restart mysql on master

3. Modify my.cnf on the slave to set a server-id 

   Code Block
   [mysqld] server-id=2

4. Restart mysql on slave

5. Create a replication user on the master 

   Code Block
   mysql> CREATE USER 'repl'@'%' IDENTIFIED BY 'slavepass'; mysql> GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%';

   In a real setup, you probably want to restrict the hostname instead of '%'. Depending on your mysql version, you may need to use old_password 

   Code Block
   mysql> SET PASSWORD FOR 'repl'@'%' = OLD_PASSWORD('slavepass');

6. Obtain the master status 

   Code Block
   mysql > SHOW MASTER STATUS; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000003 | 73 | test | manual,mysql | +------------------+----------+--------------+------------------+

7. Set master on the slave 

   Code Block
   mysql> CHANGE MASTER TO -> MASTER_HOST='master_host_name', -> MASTER_USER='replication_user_name', // repl -> MASTER_PASSWORD='replication_password', //slavepass -> MASTER_LOG_FILE='recorded_log_file_name', //mysql-bin.000003 -> MASTER_LOG_POS=recorded_log_position; // 73

8. Start slave 

   Code Block
   mysql> start slave

9. Verify slave status 

   Code Block

   mysql> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: localhost Master_User: root Master_Port: 13000 Connect_Retry: 60 Master_Log_File: master-bin.000002 Read_Master_Log_Pos: 1307 Relay_Log_File: slave-relay-bin.000003 Relay_Log_Pos: 1508 Relay_Master_Log_File: master-bin.000002 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 1307 Relay_Log_Space: 1858 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1 Master_UUID: 3e11fa47-71ca-11e1-9e33-c80aa9429562 Master_Info_File: /var/mysqld.2/data/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for the slave I/O thread to update it Master_Retry_Count: 10 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: 3e11fa47-71ca-11e1-9e33-c80aa9429562:1-5 Executed_Gtid_Set: 3e11fa47-71ca-11e1-9e33-c80aa9429562:1-5 Auto_Position: 1 Replicate_Rewrite_DB: Channel_name:
