這篇文章介紹了使用ShardingSphere-Proxy實現(xiàn)分表分庫的方法，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

1. 環(huán)境準(zhǔn)備

MySql 5.7
apache-shardingsphere-4.1.1-sharding-proxy-bin.tar.gz
jdk 1.8
mysql-connector-java-5.1.49.jar

2. 數(shù)據(jù)庫腳本準(zhǔn)備

# 創(chuàng)建商品數(shù)據(jù)庫
CREATE DATABASE IF NOT EXISTS `products` DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_general_ci;
# 創(chuàng)建商品代理數(shù)據(jù)庫
CREATE DATABASE IF NOT EXISTS `products-proxy` DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_general_ci;

# 創(chuàng)建商品秒殺表
CREATE TABLE IF NOT EXISTS `seckills` (
	`Id` INT(11) NOT NULL AUTO_INCREMENT,
	`SeckillType` INT(11) NOT NULL,
	`SeckillName` TEXT NULL,
	`SeckillUrl` TEXT NULL,
	`SeckillPrice` DECIMAL(18, 2) NOT NULL,
	`SeckillStock` INT(11) NOT NULL,
	`SeckillPercent` TEXT NULL,
	`TimeId` INT(11) NOT NULL,
	`ProductId` INT(11) NOT NULL,
	`SeckillLimit` INT(11) NOT NULL,
	`SeckillDescription` TEXT NULL,
	`SeckillIstop` INT(11) NOT NULL,
	`SeckillStatus` INT(11) NOT NULL,
PRIMARY KEY (`Id`),
INDEX `ProductId` (`ProductId`)
) COLLATE = 'utf8mb4_general_ci' ENGINE = INNODB AUTO_INCREMENT = 2;

# 插入秒殺商品數(shù)據(jù)
INSERT INTO `seckills`(`Id`, `SeckillType`, `SeckillName`, `SeckillUrl`, `SeckillPrice`, `SeckillStock`, `SeckillPercent`, `TimeId`, `ProductId`, `SeckillLimit`, `SeckillDescription`, `SeckillIstop`, `SeckillStatus`) VALUES (1, 1, '22', 'https://img2020.cnblogs.com/blog/1191201/202007/1191201-20200720143227139-1714696954.png', 12.00, 2222, '1', 3, 1, 1, 'iphone6是最好的', 1, 1);

INSERT INTO `seckills`(`Id`, `SeckillType`, `SeckillName`, `SeckillUrl`, `SeckillPrice`, `SeckillStock`, `SeckillPercent`, `TimeId`, `ProductId`, `SeckillLimit`, `SeckillDescription`, `SeckillIstop`, `SeckillStatus`) VALUES (2, 1, '22', 'https://img2020.cnblogs.com/blog/1191201/202007/1191201-20200720143227139-1714696954.png', 12.00, 2222, '1', 3, 2, 1, 'iphone6是最好的', 1, 1);

INSERT INTO `seckills`(`Id`, `SeckillType`, `SeckillName`, `SeckillUrl`, `SeckillPrice`, `SeckillStock`, `SeckillPercent`, `TimeId`, `ProductId`, `SeckillLimit`, `SeckillDescription`, `SeckillIstop`, `SeckillStatus`) VALUES (3, 1, '22', 'https://img2020.cnblogs.com/blog/1191201/202007/1191201-20200720143227139-1714696954.png', 12.00, 2222, '1', 3, 3, 1, 'iphone6是最好的', 1, 1);

INSERT INTO `seckills`(`Id`, `SeckillType`, `SeckillName`, `SeckillUrl`, `SeckillPrice`, `SeckillStock`, `SeckillPercent`, `TimeId`, `ProductId`, `SeckillLimit`, `SeckillDescription`, `SeckillIstop`, `SeckillStatus`) VALUES (4, 1, '22', 'https://img2020.cnblogs.com/blog/1191201/202007/1191201-20200720143227139-1714696954.png', 12.00, 2222, '1', 3, 4, 1, 'iphone6是最好的', 1, 1);

3. 配置 ShardingSphere-Proxy

解壓 ShardingSphere 到 apache-shardingsphere-4.1.1-sharding-proxy-bin 文件夾

有些 jar 包名稱過長導(dǎo)致解壓失敗，運行時會缺包報錯，如：

Starting the Sharding-Proxy ...
Exception in thread "main" Cannot create property=orchestration for JavaBean=org.apache.shardingsphere.shardingproxy.config.yaml.YamlProxyServerConfiguration@1517365b
 in 'reader', line 24, column 1:
    orchestration:
    ^
Type org.apache.shardingsphere.orchestration.center.yaml.config.YamlCenterRepositoryConfiguration not present
 in 'reader', line 25, column 3:
      orchestration_ds:

推薦到 linux 系統(tǒng)下通過 tar -zxvf apache-shardingsphere-4.1.1-sharding-proxy-bin.tar.gz 命令解壓

復(fù)制 mysql-connector-java-5.1.49.jar 到 ShardingSphere 的 bin 目錄中

修改 conf 目錄下的 config-sharding.yaml 配置文件：

# 3. 創(chuàng)建客戶端連接庫
schemaName: products-proxy

# 1. 設(shè)置 MySQL 數(shù)據(jù)源
dataSources:
  ds:
    url: jdbc:mysql://127.0.0.1:3306/products?serverTimezone=UTC&useSSL=false
    username: root
    password: 1010
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50

# 2. 設(shè)置分片規(guī)則 - 分表
shardingRule:
  tables:
    seckills: # 邏輯表名
      actualDataNodes: ds.seckills_${0..1} # 分 2 張表
      tableStrategy: # 分表策略
        inline:
          shardingColumn: ProductId # 分表字段
          algorithmExpression: seckills_${ProductId % 2} # 對 ProductId 取模分表

修改 conf 目錄下的 server.yaml 配置文件：

authentication:
  users:
    root:
      password: 123456
    sharding:
      password: sharding 
      authorizedSchemas: products-proxy

props:
  max.connections.size.per.query: 1
  acceptor.size: 16  # The default value is available processors count * 2.
  executor.size: 16  # Infinite by default.
  proxy.frontend.flush.threshold: 128  # The default value is 128.
    # LOCAL: Proxy will run with LOCAL transaction.
    # XA: Proxy will run with XA transaction.
    # BASE: Proxy will run with B.A.S.E transaction.
  proxy.transaction.type: LOCAL
  proxy.opentracing.enabled: false
  proxy.hint.enabled: false
  query.with.cipher.column: true
  sql.show: false
  allow.range.query.with.inline.sharding: false

啟動 ShardingSphere-Proxy

D:\Program\Java\apache-shardingsphere-4.1.1-sharding-proxy-bin\bin>start.bat

# 通過啟動日志查看代理數(shù)據(jù)庫的默認(rèn)端口是 3307

# 新建 mysql 和  mysql-proxy 兩個連接備用

在 mysql 連接中，新建 products 和 products-proxy數(shù)據(jù)庫
刷新 mysql-proxy 連接，就會看到數(shù)據(jù)庫已經(jīng)同步過來
打開 mysql-proxy 連接下的 products-proxy 數(shù)據(jù)庫，執(zhí)行創(chuàng)建 seckills 表的語句
打開 mysql 連接下的 products 數(shù)據(jù)庫，就會發(fā)現(xiàn) sekills_0 和 seckills_1 兩張拆分的表
