环境：
Master：
ip 192.168.1.110
os rhel-5.8
mysql 5.5.28
Slave：
ip 192.168.1.113
os rhel-5.8
mysql 5.5.28
① 主my.cnf的配置
[root@localhost ~]# cat /etc/my.cnf
[mysqld]
log-bin=mysql-bin #打开mysql二进制日志
binlog-do-db=test #设置二进制日志记录的库
server-id = 1 #设置mysql_id，主从不能相同
binlog-ignore-db=mysql #设置二进制日志不记录的库
sync_binlog=1 #设置binlog有更新的时候刷新到磁盘
② 登入主库
mysql> use mysql;
mysql> grant replication slave,file on *.* to 'Think'@'192.168.1.113' identified by 'mysql';
mysql> flush privileges;
查看主库状态，并记录File和Position
mysql> show master status\G;
*************************** 1. row ***************************
File: mysql-bin.000002
Position: 107
Binlog_Do_DB: test
Binlog_Ignore_DB: mysql
1 row in set (0.00 sec)
③ 从my.cnf的配置
[root@localhost ~]# cat /etc/my.cnf
[mysqld]
log-bin=mysql-bin
server-id = 2
replicate-do-db=test
replicate-ignore-db=mysql
log-slave-updates
sync_binlog=1
slave-net-timeout=10
④ 从库change master
mysql> stop slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> change master to
-> master_host='192.168.1.110',master_user='Think',master_password='mysql',

Query OK, 0 rows affected (0.10 sec)
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status\G;
