sharding-proxy+sharding-ui安裝使用配置

sharding-proxy+sharding-ui安裝使用配置

sharding官網

https://shardingsphere.apache.org/document/current/cn/manual/sharding-proxy/

運行mysql(已運行則略)

啟動zookeeper(已啟動則略)

sharding-proxy安裝啟動配置

• 下載sharding-proxy(這里沒有采用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

• 解壓

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

• 進入conf vim server.yaml

修改 config-sharding.yaml

• mysql建測試庫和表

庫名表名要和配置文件內容相匹配，sharding-proxy不會自己給你新建真實庫和表

• 下載mysql連接驅動

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

• 解壓后放到lib目錄下

• 啟動 bin/start.sh

• 

• 查看日志

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

• 啟動成功

  

• Navicat連接proxy代理數據源

代理數據源的schema和table啟動后自己建好了 登錄信息在conf目錄下的server.yaml

sharding-ui啟動使用

• 下載

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

• 解壓

  

• 查看sharding-ui的配置文件

  

• 啟動sharding-ui bin/start.sh

  

• 查看日志是否成功

• 瀏覽器訪問服務器ip:8088

  

  端口、用戶名、密碼在sharding-ui下conf下application.properties配置

• 添加注冊中心

  

  參考sharding-proxy下conf下server.yaml

• 連接

  

• 運行狀態

  

  運行狀態下就可以看到運行的sharding-proxy服務節點了

• 添加服務中心

  

• 配置管理

  

連接后會自動把配置信息展示在界面上

比如我們可以更改數據源中的數據重新定義分庫分表規則

也可以定義多個數據源

后端微服務可以配置代理數據源即可實現分庫分表
