Create MySQL user in Primary (Master) server with name slave and password loyalty

CREATE USER 'slave'@'slave's IP address' IDENTIFIED BY PASSWORD 'loyalty';

GRANT REPLICATION SLAVE ON * . * TO 'slave'@'slave's IP address' IDENTIFIED BY PASSWORD 'loyalty' WITH MAX_QUERIES_PER_HOUR 0  
MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

GRANT SELECT ON `mor` . * 
TO 'dataslave'@'slave's IP address';

Now use this configuration in Primary server's MySQL configuration file which is located in /etc/my.cnf

Master's config file (/etc/my.cnf)

Use this configuration in Second server (Slave)

Don't forget to change "Masters.ip.address" to PRIMARY servers IP address

In Primary server: Switch off Asterisk and Apache and dump MOR database:

mysqldump -uUser -pPassword mor >/root/mor.sql
scp /root/mor.sql root@SLAVE's ip address:/root

Now in Second server:

mysql -u root -p -e "CREATE DATABASE MOR"

If you get noticed that DB already exists, make sure to DROP (DROP DATABASE MOR) it out and then try to create MOR database again. Now import dump of real MOR database which is from Primary server:

mysql -D mor </root/mor.sql

If everything was fine you shouldn't get any errors
