MySQL5.7多源复制
MySQL5.7开始支持多源复制，也就是多主一从的复制架构：
使用多源复制的考虑：
1、灾备作用：将各个库汇总在一起，就算是其他库都挂了（整个机房都无法连接了），还有最后一个救命稻草；
2、备份：直接在这个从库中做备份，不影响线上的数据库；
3、减少成本：不需要每个库都做一个实例，也减少了DBA的维护成本；
4、数据统计：后期的一些数据统计，需要将所有的库汇总在一起。
... ...
实验环境：
Master1：10.157.26.132:3307
Master2：10.157.26.133:3307
Slave：10.157.26.134:3307
多源复制是支持GTID和Binlog+Position，我这里是GTID复制。
MySQL5.7的安装这里不再介绍，可以查看http://www.cnblogs.com/lizhi221/p/6813907.html
一、配置文件：
Master1和Master2:
#GTID
gtid-mode = on
binlog_gtid_simple_recovery=1
enforce_gtid_consistency=1
binlog_format = row
skip_slave_start = 1
log-bin = /data/mysql/mysql_3307/logs/binlog/mysql-bin
Slave:
#binlog
binlog_format = row
server-id = 1343307
log-bin = /data/mysql/mysql_3307/logs/binlog/mysql-bin
#GTID
gtid-mode = on
binlog_gtid_simple_recovery=1
enforce_gtid_consistency=1
#修改MySQL存储master-info和relay-info的方式，即从文件存储改为表存储
master_info_repository=TABLE
relay_log_info_repository=TABLE
replicate_ignore_db=mysql #忽略mysql库的同步
skip_slave_start = 1
二、主库创建复制账号：
Master1：grant replication slave,replication client on *.* to sampson_132@'10.157.26.%'identified by 'sampson_132';
Master2：grant replication slave,replication client on *.* to sampson_133@'10.157.26.%'identified by 'sampson_133';
三：从库启动复制：
mysql> change master to master_host='10.157.26.132',master_port=3307,master_user='sampson_132',master_password='sampson_132',master_auto_position=1 for channel 'Master_132';
mysql>change master to master_host='10.157.26.133',master_port=3307,master_user='sampson_133',master_password='sampson_133',master_auto_position=1 for channel 'Master_133';
mysql>start slave;
也可以start slave for channel 'Master_132 '启动单个channel的复制。
四：查看slave状态
【也可以直接show slave status for channel 'Master_132' \G查看各个channel的复制状态】
mysql> show slave status\G

通过查看performance_schema相关的表查看同步状态：

2 rows in set (0.01 sec)
五、数据同步检查：
Master1建库建表并插入数据：
mysql>CREATE DATABASE /*!32312 IF NOT EXISTS*/ `sampson_132` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;
mysql>use sampson_132
mysql> create table t_132(id int primary key auto_increment,name varchar(20) not null);
mysql> insert into t_132(id,name)values(1,''),(2,''),(3,'');
mysql> select * from t_132;
+----+------+
| id | name |
+----+------+
| 1 | 132 |
| 2 | 132 |
| 3 | 132 |
+----+------+
3 rows in set (0.00 sec)
Master2建库建表并插入数据：
mysql> CREATE DATABASE /*!32312 IF NOT EXISTS*/ `sampson_133` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;
mysql> use sampson_133
mysql> create table t_133(id int primary key auto_increment,name varchar(20) not null);
mysql> insert into t_133(id,name)values(1,''),(2,''),(3,'');
mysql> select * from sampson_133.t_133;
+----+------+
| id | name |
+----+------+
| 1 | 133 |
| 2 | 133 |
| 3 | 133 |
+----+------+
3 rows in set (0.00 sec)
Slave查看数据是否同步：
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sampson_132 |
| sampson_133 |
| sys |
+--------------------+
6 rows in set (0.00 sec) mysql> select * from sampson_132.t_132;
+----+------+
| id | name |
+----+------+
| 1 | 132 |
| 2 | 132 |
| 3 | 132 |
+----+------+
3 rows in set (0.00 sec) mysql> select * from sampson_133.t_133;
+----+------+
| id | name |
+----+------+
| 1 | 133 |
| 2 | 133 |
| 3 | 133 |
+----+------+
3 rows in set (0.00 sec)
再次查看从库状态：
mysql> show slave status\G
