在windows安装部署ShardingSphere-Proxy 分库分表中间件

当前端口：

-- mysql端口：3316；数据库：myshop1；表：t_product_1、t_product_2
-- mysql端口：3326；数据库：myshop2；表：t_product_1、t_product_2

分库分表策略：按照 id%2 分库，按照 create_time%2 分表。

1、下载ShardingSphere-Proxy
ShardingSphere-Proxy 二进制包: [ TAR ]

下载地址：https://shardingsphere.apache.org/document/current/cn/downloads/

当前版本是：apache-shardingsphere-5.0.0-alpha-shardingsphere-proxy

2、修改bin目录的配置config-sharding.yaml内容

schemaName: sharding_db

dataSourceCommon:
username: root
password: 123456
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1
maintenanceIntervalMilliseconds: 30000

dataSources:
ds_0:
url: jdbc:mysql://localhost:3316/myshop1?useUnicode=true&characterEncoding=utf-8
ds_1:
url: jdbc:mysql://localhost:3326/myshop2?useUnicode=true&characterEncoding=utf-8

rules:
- !SHARDING
tables:
t_product:
actualDataNodes: ds_${0..1}.t_product_${0..1}
tableStrategy:
standard:
shardingColumn: create_time
shardingAlgorithmName: t_product_inline
keyGenerateStrategy:
column: id
keyGeneratorName: snowflake
bindingTables:
- t_product
defaultDatabaseStrategy:
standard:
shardingColumn: id
shardingAlgorithmName: database_inline
defaultTableStrategy:
none:

shardingAlgorithms:
database_inline:
type: INLINE
props:
algorithm-expression: ds_${id % 2}
t_product_inline:
type: INLINE
props:
algorithm-expression: t_product_${create_time % 2}

keyGenerators:
snowflake:
type: SNOWFLAKE
props:
worker-id: 123

3、修改bin目录的配置server.yaml内容

governance:
name: governance_ds
registryCenter:
type: ZooKeeper
serverLists: localhost:2181
props:
retryIntervalMilliseconds: 500
timeToLiveSeconds: 60
maxRetries: 3
operationTimeoutMilliseconds: 500
overwrite: false

authentication:
users:
root:
password: root
sharding:
password: sharding
authorizedSchemas: sharding_db

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
check-table-metadata-enabled: false

4、添加驱动包

mysql-connector-java-8.0.23.jar

要与你的mysql版本一致，不然会报错的：com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Exception during pool initialization.

5、启动zookeeper

配置文件的内容会存到zk中。

启动shardingsphere-proxy之后，会把配置信息存到zk的。如果修改了配置，再次启动shardingsphere-proxy，发现zk的没有同步修改，需要手动删掉zk的数据，shardingsphere-proxy启动后会再生成的。

6、启动shardingsphere-proxy

点击bin/start.bat

如果最后命令行显示： [main] o.a.s.p.frontend.ShardingSphereProxy - ShardingSphere-Proxy start success.，就表示成功了。

ShardingSphereProxy会在3307端口启用一个mysql连接。

连接mysql，端口3307，用户名密码：root，root。

然后就可以查询和操作了。
