mysql5.5 master slave of Replication master slave configuration

1 master 1 from:
Master:
OS:centos release 5.6 DB:mysql 5.5.8 IP:192.168.1.2
Slave:
OS:centos release 5.6 DB:mysql 5.5.8 IP:192.168.1.3
Modify the host Master configuration file (/etc/ my.cnf)

 
[mysqld] 
// There must be at least server-id , and log-bin two  
server-id=1 
log-bin=/var/lib/mysql/mysql-bin 
datadir=/var/lib/mysql 
// In order to use transactions InnoDB Maximum persistence and in replication 1 Sex, you should specify innodb_flush_log_at_trx_commit=1,sync_binlog=1 options  
innodb_flush_log_at_trx_commit=1 
sync_binlog=1 

Create a user with replication privileges on host Master
mysql > create user repl_user@192.168.1.3;
mysql > grant replication slave on *.* to repl_user@192.168.1.3 identified by '123456';
Lock the host and record the location of the binary log (this will be used when setting the slave later)
mysql > flush tables with read lock;
mysal > show master status;
File: mysql-bin.000013 Position: 7863951
Copy the host database (test) to the slave
shell > /usr/bin/mysqldump test -uroot -padmin --opt | mysql test -uroot -padmin -h 192.168.1.3
Reopen the host Master write function
mysql > unlock tables;

Modify the slave Slave configuration file (/etc/ my.cnf)

 
[mysqld] 
server-id=2 // It must be 1 to 2 the 32 Between powers 1 Integer, and must be with the host Master the server-id Don't 1 sample  
relay-log-index=slave-relay-bin.index 
relay-log=slave-relay-bin 
replicate-do-db=test // Specify replication database  
datadir=/var/lib/mysql 

The slave Slave initializes the copy
mysql > slave stop;
mysql > change master to master_host='192.168.1.2',
- > master_user='repl_user',
- > master_password='123456',
- > master_log_file='mysql-bin.000013',
- > master_log_pos=7863951;
Open the copy
mysql > start slave;
View replication status
mysql > show slave status\G
Test copy:
Perform sql operations on the test database in host master, and check to see if the slave test database generates synchronization.
