當前端口：
-- mysql端口：3316；數據庫：myshop1；表：t_product_1、t_product_2
-- mysql端口：3326；數據庫：myshop2；表：t_product_1、t_product_2
分庫分表策略：按照 id%2 分庫，按照 create_time%2 分表。
1、下載ShardingSphere-Proxy
ShardingSphere-Proxy 二進制包: [ TAR ]
下載地址：https://shardingsphere.apache.org/document/current/cn/downloads/
當前版本是：apache-shardingsphere-5.0.0-alpha-shardingsphere-proxy
2、修改bin目錄的配置config-sharding.yaml內容
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目錄的配置server.yaml內容
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、添加驅動包
mysql-connector-java-8.0.23.jar
要與你的mysql版本一致，不然會報錯的：com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Exception during pool initialization.
5、啟動zookeeper
配置文件的內容會存到zk中。
啟動shardingsphere-proxy之后，會把配置信息存到zk的。如果修改了配置，再次啟動shardingsphere-proxy，發現zk的沒有同步修改，需要手動刪掉zk的數據，shardingsphere-proxy啟動后會再生成的。
6、啟動shardingsphere-proxy
點擊bin/start.bat
如果最后命令行顯示： [main] o.a.s.p.frontend.ShardingSphereProxy - ShardingSphere-Proxy start success.，就表示成功了。
ShardingSphereProxy會在3307端口啟用一個mysql連接。
連接mysql，端口3307，用戶名密碼：root，root。
然后就可以查詢和操作了。
