Mysql master-slave replication breaks when issuing commands from master's phpmyadmin - mysql

Question

I have successfully configured MYSQL slave from existing master SQL server using this https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-in-mysql
The setup works fine and changes made to master through MySQL shell are perfectly reflected on the slave. But if I issue commands from PHPMyAdmin, the system breaks down. it shows following error
mysql> show slave status \G

Phpmyadmin is not configured on the slave(I installed it without configuring it to slave parameters) and in the master configuration, I've explicitly set PHPmyadmin to not get replicated on slave through the following command.
binlog_ignore_db = phpmyadmin
How to remove this error
'phpmyadmin.pma_table_uiprefs' doesn't exist'
please guide.

Answer 1

The problem it's that the system it's trying to replicate the phpadmin tables that doesn't exist in your replica. To make it work, you need to exclude the phpmyadmin db.
In the slave mysqld.cnf file, you need to add this:
replicate-ignore-db=phpmyadmin
and restart the replica

Answer 2

So I have solved the issue by following steps
installing MySQL and PHPMyAdmin on slave through following guide http://usefulangle.com/post/35/how-to-install-linux-apache-mysql-php-phpmyadmin-lamp-stack-on-ubuntu-16-04
importing PHPMyAdmin tables from my master DB to slave DB. The problems were occurring due to the mismatch in table names in master and slave phpmyadmin tables.
What I've not understood is why slave was replicating PHPMyAdmin tables despite setting binlog_ignore_db = phpmyadmin in master configuration.
