1、两台机器，安装好版本一致的MySQL
192.168.29.128 （master） MySQL-5.6.21
192.168.29.129 （slave） MySQL-5.6.21
2、配置master
配置binary log和server ID
[root@Luxh-01 ~]# vi /etc/my.cnf
配置如下：
[mysqld]
log-bin=mysql-bin
server-id=1
重启MySQL
3、配置slave
[mysqld]
server-id=2
4、在master上创建用于复制的账号
mysql> create user 'repl'@'%' identified by '';
Query OK, 0 rows affected (0.13 sec) mysql> grant replication slave on *.* to 'repl'@'%' ;
Query OK, 0 rows affected (0.02 sec)
5、在master上查看 binary log文件名和 position
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000003 | 120 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
6、配置slave
mysql> change master to master_host='192.168.29.128',master_user='repl',master_password='',master_port=3306,master_log_file='mysql-bin.000003',master_log_pos=120,master_connect_retry=10;
Query OK, 0 rows affected, 2 warnings (0.30 sec)
使用上面创建的用于复制的账号，master_log_file使用master上查询出来的文件名，master_log_pos也必须使用master上查询出来的position
7、在slave上启动复制功能
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
8、查看slave的状态
mysql> show slave status\G;

9、配置完毕。测试一下效果。
1）在master上执行以下语句
mysql> create database web_db;
Query OK, 1 row affected (0.04 sec) mysql> use web_db;
Database changed
mysql> create table t_user(id int primary key auto_increment,username varchar(32));
Query OK, 0 rows affected (0.13 sec) mysql> insert into t_user(username) values('lihuai');
Query OK, 1 row affected (0.05 sec) mysql> select * from t_user;
+----+----------+
| id | username |
+----+----------+
| 1 | lihuai |
+----+----------+
1 row in set (0.00 sec)
2）在slave上查看，看是否已成功复制
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
| web_db |
+--------------------+
5 rows in set (0.05 sec) mysql> use web_db;
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> show tables;
+------------------+
| Tables_in_web_db |
+------------------+
| t_user |
+------------------+
1 row in set (0.00 sec) mysql> select * from t_user;
+----+----------+
| id | username |
+----+----------+
| 1 | lihuai |
+----+----------+
1 row in set (0.00 sec)
10、以上配置是针对全新安装的MySQL服务器做主从复制，还可以针对已有数据的数据库、或者已有的主从结构上再添加slave
具体配置，可以参考官网文档，非常详细。
