Mycat的安装及配置

一、安装并启动mycat

1.下载mycat并解压，下载地址：http://dl.mycat.io/1.6-RELEASE/Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz

2.编辑mycat/conf/schema.xml

<?xml version="1.0"?>
<!DOCTYPE mycat:schema SYSTEM "schema.dtd">
<mycat:schema xmlns:mycat="http://io.mycat/">

    <schema name="e3mall-32" checkSQLschema="false" sqlMaxLimit="100">
        <!-- auto sharding by id (long) -->
        <table name="tb_item" dataNode="dn1,dn2,dn3" rule="auto-sharding-long" />
    </schema>
    <!-- <dataNode name="dn1$0-743" dataHost="localhost1" database="db$0-743"
        /> -->
    <dataNode name="dn1" dataHost="localhost1" database="db1" />
    <dataNode name="dn2" dataHost="localhost2" database="db2" />
    <dataNode name="dn3" dataHost="localhost1" database="db3" />
    <dataHost name="localhost1" maxCon="1000" minCon="10" balance="0"
              writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
        <heartbeat>select user()</heartbeat>
        <!-- can have multi write hosts -->
        <writeHost host="hostM1" url="192.168.25.128:3306" user="root"
                   password="123456">
            <!-- can have multi read hosts -->
            
        </writeHost>
    </dataHost>
    <dataHost name="localhost2" maxCon="1000" minCon="10" balance="0"
              writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
        <heartbeat>select user()</heartbeat>
        <!-- can have multi write hosts -->
        <writeHost host="hostM1" url="192.168.25.129:3306" user="root"
                   password="123456">
            <!-- can have multi read hosts -->
            
        </writeHost>
    </dataHost>
</mycat:schema>

3.编辑mycat/conf/server.xml，在文件末尾只保留一个user节点，并删掉该节点的readOnly元素

    <user name="user">
        <property name="password">123456</property>
        <property name="schemas">e3mall-32</property>
    </user>

4.启动

./mycat start

注：mycat 支持的命令{ console | start | stop | restart | status | dump }

5.使用navicat连接mycat，创建表

-- ----------------------------
-- Table structure for tb_item
-- ----------------------------
DROP TABLE IF EXISTS `tb_item`;
CREATE TABLE `tb_item` (
  `id` bigint(20) NOT NULL COMMENT '商品id，同时也是商品编号',
  `title` varchar(100) NOT NULL COMMENT '商品标题',
  `sell_point` varchar(500) DEFAULT NULL COMMENT '商品卖点',
  `price` bigint(20) NOT NULL COMMENT '商品价格，单位为：分',
  `num` int(10) NOT NULL COMMENT '库存数量',
  `barcode` varchar(30) DEFAULT NULL COMMENT '商品条形码',
  `image` varchar(500) DEFAULT NULL COMMENT '商品图片',
  `cid` bigint(10) NOT NULL COMMENT '所属类目，叶子类目',
  `status` tinyint(4) NOT NULL DEFAULT '1' COMMENT '商品状态，1-正常，2-下架，3-删除',
  `created` datetime NOT NULL COMMENT '创建时间',
  `updated` datetime NOT NULL COMMENT '更新时间',
  PRIMARY KEY (`id`),
  KEY `cid` (`cid`),
  KEY `status` (`status`),
  KEY `updated` (`updated`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='商品表';

6.插入数据

7.分片测试

auto-sharding-long规则根据id分片，本测试用的db1到db3，所以插入0~5000000，5000000~10000000，10000000~15000000的id数据来测试

二、mycat读写分离

1.配置主从复制

主从配置需要注意

● 主DB server和从DB server数据库的版本一致

● 主DB server和从DB server数据库数据名称一致

● 主DB server开启二进制日志,主DB server和从DB server的server_id都必须唯一

a.主服务器配置

1)修改my.conf文件，在[mysqld]段下添加：

binlog-do-db=db1
binlog-ignore-db=mysql
#启用二进制日志
log-bin=mysql-bin
#服务器唯一ID，一般取IP最后一段
server-id=128

2)重启mysql

3)建立帐户并授权slave

mysql>GRANT FILE ON *.* TO 'backup'@'%' IDENTIFIED BY '123456';
mysql>GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* to 'backup'@'%' identified by '123456'; 

一般不用root帐号，“%”表示所有客户端都可能连

4)刷新权限

mysql> FLUSH PRIVILEGES;

5)查看主服务器状态

mysql> show master status;

b.从服务器配置

1)修改my.conf，一般修改server-id成ip地最后一段

[mysqld]
server-id=129

2)关联主服务器

mysql>change master to master_host='192.168.25.128',master_port=3306,master_user='backup',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=120

其中master_log_file和master_log_pos填上面show master status中看到的值

2.配置读写分离

            <readHost host="hostS" url="192.168.25.129:3306" user="root"

    </dataHost>
    <dataHost name="localhost2" maxCon="1000" minCon="10" balance="0"

            <!-- can have multi read hosts -->
        </writeHost>
    </dataHost>
</mycat:schema>

注：

balance=“1”，所有读操作都随机的发送到readHost

writeType=“0”, 所有写操作都发送到可用的writeHost上

switchType="2",基于mysql主从同步状态决定是否切换

show slave status,心跳检测语句
