1.啟動多台 soul-admin
2.啟動多台 soul-bootstrap
3.啟動多台業務系統
4.驗證同步
4.1 負載均衡
4.2 資料同步
1.啟動多台 soul-admin
修改配置檔案，把可以開啟允許并行執行的複選框。
application.yml
server: port: 9095 server: port: 9096
啟動後狀态：
2.啟動多台 soul-bootstrap
跟上面的一樣，修改配置檔案，打開并行執行的開關。
application-local.yml
server:
port: 9195
server:
port: 9196
使用預設的同步資料政策 websocket，需要配置多個 soul-admin 的位址：
sync: websocket : urls: ws://localhost:9095/websocket,ws://localhost:9096/websocket
啟動後狀态：
3.啟動多台業務系統
我們使用 examples 中自帶的 soul-examples-http，啟動兩個節點。
修改配置檔案 application.yml
server:
port: 8188
address: 0.0.0.0
soul:
http:
adminUrl: http://localhost:9095
port: 8188
contextPath: /http
appName: http
full: false
server:
port: 8189
address: 0.0.0.0
soul:
http:
adminUrl: http://localhost:9095
port: 8189
contextPath: /http
appName: http
full: false
這裡的 adminUrl 配置一個 soul-admin 即可，連接配接上一個之後，隻要能把資料同步過去，其他的節點也都可以通過資料庫拿到同步後的資料。
啟動後狀态：
4.驗證同步
4.1 負載均衡
【插件清單】【divide】【選擇器清單】【修改】
2個 soul-bootstrap 節點，配置都一緻，預設權重 weight 為50，我們調用幾次接口，驗證負載均衡。
連續調用6次 http://localhost:9195/http/order/findById?id=95 GET 請求，可以在 soul-bootstrap:9195 console 列印如下日志：
可以看到 "The request urlPath is" 輪流調用 8188 和 8189 兩個業務服務節點，因為 weight 都是50，調用比例為 1:1，結果就跟輪詢調用一樣。

4.2 資料同步
在 9095 修改權重，然後調用接口，檢視是否按照修改後的權重發送請求：
8188 weight 30，8189 weight 60。
從日志中可以看到，調用1次8188，就會調用2次8189，符合預期比例 30:60=1:2。
