how to configure mysql master slave replication

how to configure mysql master slave replication 

Here  is a basic step by step tutorial, that will cover the mysql master and slave replication and also will describe the mysql master and master replication.

 Step 1:

Install mysql on master 1 and slave 1. configure network services on both system, like

Master  ip: 192.168.16.4
Slave  ip : 192.168.16.5

Step 2:

On Master 1, make changes in my.cnf:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
old_passwords=1

log-bin
binlog-do-db=<database name>  # input the database which should be replicated
binlog-ignore-db=mysql            # input the database that should be ignored for replication
binlog-ignore-db=test

server-id=1

[mysql.server]
user=mysql
basedir=/var/lib


[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

Step 3:

On master 1, create a replication slave account in mysql.

mysql> grant replication slave on *.* to 'replication'@192.168.16.5 \
identified by 'slave';

and restart the mysql master1.

Step 4:

Now edit my.cnf on Slave1 or Master2 :
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
old_passwords=1
server-id=2

master-host = 192.168.16.4
master-user = replication
master-password = slave
master-port = 3306

[mysql.server]
user=mysql
basedir=/var/lib

[mysqld_safe]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

Step 5:

Restart mysql slave 1 and at

mysql> start slave;
mysql> show slave status\G;

Step 6:

On master 1:
mysql> show master status;
