Sharding-Proxy是单独的一个应用，需要独立部署。

1. 下载安装包

[root@sit_mysql1 ~]# cd /usr/local/src/
[root@sit_mysql1 src]# wget https://github.com/sharding-sphere/sharding-sphere-doc/raw/master/dist/sharding-proxy-3.0.0.tar.gz

2. 解压缩

[root@sit_mysql1 src]# tar zxvf sharding-proxy-3.0.0.tar.gz -C /usr/local/

3.分库分表和读写分离配置：

解压后，进入conf目录，里面有对应的yaml配置文件，Sharding-Proxy支持多逻辑数据源，每个以config-前缀命名的yaml配置文件，即为一个逻辑数据源。这里配置了2个例子，一个是分库分表的，一个是读写分离的。
分库分表，文件名为config-sharding.yaml，具体内容如下：

schemaName: sharding_db

dataSources:
  ds0: 
    url: jdbc:mysql://10.0.0.1:3306/ds0
    username: dba_01
    password: 123456
    autoCommit: true
    connectionTimeout: 30000
    idleTimeout: 60000
    maxLifetime: 1800000
    maximumPoolSize: 65
  ds1:
    url: jdbc:mysql://10.0.0.2:3306/ds1
    username: dba_01
    password: 123456
    autoCommit: true
    connectionTimeout: 30000
    idleTimeout: 60000
    maxLifetime: 1800000
    maximumPoolSize: 65

shardingRule:  
  tables:
    t_order: 
      actualDataNodes: ds${0..1}.t_order${0..1}
      tableStrategy: 
        inline:
          shardingColumn: order_id
          algorithmExpression: t_order${order_id % 2}
      keyGeneratorColumnName: order_id
    t_order_item:
      actualDataNodes: ds${0..1}.t_order_item${0..1}
      tableStrategy:
        inline:
          shardingColumn: order_id
          algorithmExpression: t_order_item${order_id % 2}  
  bindingTables:
    - t_order,t_order_item
  defaultDatabaseStrategy:
    inline:
      shardingColumn: user_id
      algorithmExpression: ds${user_id % 2}
  defaultTableStrategy:
    none:
  defaultKeyGeneratorClassName: io.shardingsphere.core.keygen.DefaultKeyGenerator

读写分离，文件名为config-master_slave.yaml，具体内容如下

schemaName: master_slave_db

dataSources:
  ds_master:
    url: jdbc:mysql://10.0.0.1:3888/shardingdb
    username: dba_01
    password: 123456
    autoCommit: true
    connectionTimeout: 30000
    idleTimeout: 60000
    maxLifetime: 1800000
    maximumPoolSize: 65
  ds_slave0:
    url: jdbc:mysql://10.0.0.2:3888/shardingdb
    username: dba_01
    password: 123456
    autoCommit: true
    connectionTimeout: 30000
    idleTimeout: 60000
    maxLifetime: 1800000
    maximumPoolSize: 65 

masterSlaveRule:
  name: ds_ms
  masterDataSourceName: ds_master
  slaveDataSourceNames: 
    - ds_slave0
