Mysql Replication With Phpmyadmin

First Lets go to Replication panel on XAMPP.

Next Select Configure as Master

You can configure Replication as ALL or Selective. I have done selective where I select few DBs to Replicate.

Once you are done you need to add the lines below in the my.cnf file.

# ***** Added Lines here ****
server-id=4745869
log-bin=mysql-bin
log-error=mysql-bin.err
binlog_do_db=saggezza_cats,saggezza_catstesting
# ***** Till Here ****

Here are Ignoring all the DBs for Replication except the two above.

Go to /opt/lampp/etc/my.cnf

Added the lines as I mentioned above above. Also Make sure “max_allowed_packet = 16M”

Make sure to comment out he existing server-id as we have already given above.

Restart XAMPP

$ sudo ./opt/lampp/lampp restart

Once you restart XAMPP, you can see that Mysql Server is started as Master.

Next Lets Create a Replication user and give it privileges as the slave needs this information to connect to the Master.

I have given root but you can give any username you want.

MySQL Slave Configuration

First lets add Server-id to our slave as mentioned.

server-id=9384593

Now lets connect to Master.

You will get a confirmation about he successful connection to Master.

Now we need to start SLAVE I/O and Sql Threads.

They are right under “Control Slave” as below

Now you can see the threads running.

NOTE: If you face any issues getting the threads started then please check logs. In my case IO Thread was not starting. When I checked the log I found that I had two server-id’s in the my.cnf file. Also sometimes you will get IO error due to max_allowed_packet as well, as this is by default set to 1MB, which needs to be around 16MB.

/opt/lampp/var/mysql/mysql-bin

Now we can see all the DBs in Replication Mode. Now any Updates to Master will reflect on the slave.

This will have the MASTER-SLAVE for Mysql Server is Ready.
