sharding-proxy+sharding-ui安装使用配置

sharding官网

运行mysql(已运行则略)

启动zookeeper(已启动则略)

sharding-proxy安装启动配置

• 下载sharding-proxy(这里没有采用docker的方式)

wget https://mirrors.tuna.tsinghua.edu.cn/apache/shardingsphere/4.1.0/apache-shardingsphere-4.1.0-sharding-proxy-bin.tar.gz

• 解压

tar -xf apache-shardingsphere-4.1.0-sharding-proxy-bin.tar.gz

• 进入conf vim server.yaml

• mysql建测试库和表

库名表名要和配置文件内容相匹配，sharding-proxy不会自己给你新建真实库和表

• 下载mysql连接驱动

wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.49.tar.gz

• 解压后放到lib目录下

• 启动 bin/start.sh

• 

• 查看日志

tail -200f /root/apache-shardingsphere-4.1.0-sharding-proxy-bin/logs/stdout.log

• 启动成功

  

• Navicat连接proxy代理数据源

代理数据源的schema和table启动后自己建好了 登录信息在conf目录下的server.yaml

sharding-ui启动使用

• 下载

wget https://mirror.bit.edu.cn/apache/shardingsphere/shardingsphere-ui-4.1.0/apache-shardingsphere-4.1.0-shardingsphere-ui-bin.tar.gz 

• 解压

  

• 查看sharding-ui的配置文件

  

• 启动sharding-ui bin/start.sh

  

• 查看日志是否成功

• 浏览器访问服务器ip:8088

  

  端口、用户名、密码在sharding-ui下conf下application.properties配置

• 添加注册中心

  

  参考sharding-proxy下conf下server.yaml

• 连接

  

• 运行状态

  

  运行状态下就可以看到运行的sharding-proxy服务节点了

• 添加服务中心

  

• 配置管理

  

连接后会自动把配置信息展示在界面上

比如我们可以更改数据源中的数据重新定义分库分表规则

也可以定义多个数据源

后端微服务可以配置代理数据源即可实现分库分表
