实验环境：
CentOS release 6.6 (Final) 32位
Master:10.10.10.11
Slave1:10.10.10.7
Slave2:10.10.10.8
1) MySQL 安装 （分别在Master,Slave1,Slave2 运行如下命令）
[root@Cent01 ~]# yum install mysql-server mysql -y
[root@Cent01 ~]# service mysqld start
2）配置my.cnf
[root@Cent01 ~]# mysqladmin -u root password 123.com //修改mysql root的密码为"123.com"
[root@Cent01 ~]# vi /etc/my.cnf //修改my.cfg 配置文件,添加如下内容；
相关信息如下：
#Master
[mysqld]
log-bin=MySQL-bin //二进制文件
server-id=1 //服务ID （唯一）
#Slave1
[mysqld]
log-bin=MySQL-bin //二进制文件
server-id=2 //服务ID
#Slave2
[mysqld]
log-bin=MySQL-bin //二进制文件
server-id=3 //服务ID
保存退出之后，重启MYSQL服务：
[root@Cent01 ~]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
3）在Master上创建备份帐号；
[root@Cent01 ~]# mysql -u root -p123.com
mysql> GRANT REPLICATION SLAVE ON *.* to 'myslave'@'10.10.10.7' identified by '123.com';
Query OK, 0 rows affected (0.02 sec)
mysql> GRANT REPLICATION SLAVE ON *.* to 'myslave'@'10.10.10.8' identified by '123.com';
Query OK, 0 rows affected (0.02 sec)
查看Master状态
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| MySQL-bin.000002 | 261 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
4）Slave1 Slave2上设置
[root@Cent01 ~]mysql -u root -p123.com
mysql> change master to
-> MASTER_HOST='10.10.10.11',
-> MASTER_USER='myslave',
-> MASTER_PASSWORD='123.com',
-> MASTER_LOG_FILE='MySQL-bin.000001',
-> MASTER_LOG_POS=261;
在Slave1,Slave2上启动Slave,并查看状态；
mysql> slave start;
mysql> show slave status \G

5）测试Master,Slave同步；
1.在Master上创建数据库信息;
mysql> CREATE DATABASE info;
Query OK, 1 row affected (0.00 sec)
mysql> use info
Database changed
mysql> CREATE TABLE user (id int(3),name varchar(10));
Query OK, 0 rows affected (0.04 sec)
mysql> INSERT INTO user values (001,'zhangcheng');
Query OK, 1 row affected (0.01 sec)
2.在Slave1,Slave2上查看；
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| NINESTAR |
| info |
| mysql |
| test |
+--------------------+
5 rows in set (0.00 sec)
mysql> use info
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select * from user;
+------+------------+
| id | name |
+------+------------+
| 1 | zhangcheng |
+------+------------+
1 row in set (0.00 sec)
信息已同步！
