1. Take dump on master and restore on slave

bin/mysqldump --defaults-file=/mysqldatabase/TEST/admin/my.cnf -uroot -pmysql --master-data=2 --quick --single-transaction -vvv --force -A > /mysqldatabase/dump/TEST_all.sql

 
Functions and events options needs to be given separately while taking mysqldump

Here the denominations suggests :

–master-data=2 –> This suggests the current binary log position and doesn’t apply to the database. A manual intervention is required to apply the bin logs. If this is 1, then it automatically applies the bin log after noting down the bin log position. But a value of 2 is suggested, so that, if any error occurs during restoration, then the whole instance may get corrupted

-vvv –> Verbose. To get details of the backup during the run phase

2. Restore in slave server :

nohup /mysqldatabase/product/binary/5.7.35/bin/mysql -uroot -pmysql -S/mysqldatabase/RESTORE/admin/mysql.sock < /mysqldatabase/dump/TEST_all.sql &

 

If there are any foreign key related errors:

mysql> set global foreign_key_checks=0;

 

3. Make necessary changes in master configuration file and restart master

binlog_format=mixed
server-id = 1

 
4. Create replication user in Master instance

CREATE USER 'repl'@'172.168.190.35' IDENTIFIED BY 'repl';

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'172.168.190.35' IDENTIFIED BY 'repl';

FLUSH PRIVILEGES;

 
4. Make changes in slave configuration file and restart slave

server-id = 2
relay-log = /mysqldatabase/RESTORE/logs/target-relay-bin.index

 

5. Login into slave

CHANGE MASTER TO MASTER_LOG_FILE='TEST-mysql-bin.000005', MASTER_LOG_POS=2417,master_host='172.168.190.15', master_user='repl', master_password='repl',master_port=3306;

 
You can get the above details by checking the mysqldump

6. On slave:

mysql> START SLAVE;

mysql> show slave status\G
