【Soul源码阅读】16.启动多台admin，多个网关，形成一个集群
目录
1.启动多台 soul-admin
2.启动多台 soul-bootstrap
3.启动多台业务系统
4.验证同步
4.1 负载均衡
4.2 数据同步
1.启动多台 soul-admin
修改配置文件，把可以开启允许并行执行的复选框。
application.yml
server: port: 9095 server: port: 9096
启动后状态：
2.启动多台 soul-bootstrap
跟上面的一样，修改配置文件，打开并行执行的开关。
application-local.yml
server:
port: 9195server:
port: 9196
使用默认的同步数据策略 websocket，需要配置多个 soul-admin 的地址：
sync:
websocket :
urls: ws://localhost:9095/websocket,ws://localhost:9096/websocket
启动后状态：
3.启动多台业务系统
我们使用 examples 中自带的 soul-examples-http，启动两个节点。
修改配置文件 application.yml
server:
port: 8188
address: 0.0.0.0
soul:
http:
adminUrl: http://localhost:9095
port: 8188
contextPath: /http
appName: http
full: falseserver:
port: 8189
address: 0.0.0.0
soul:
http:
adminUrl: http://localhost:9095
port: 8189
contextPath: /http
appName: http
full: false
这里的 adminUrl 配置一个 soul-admin 即可，连接上一个之后，只要能把数据同步过去，其他的节点也都可以通过数据库拿到同步后的数据。
启动后状态：
4.验证同步
4.1 负载均衡
【插件列表】【divide】【选择器列表】【修改】
2个 soul-bootstrap 节点，配置都一致，默认权重 weight 为50，我们调用几次接口，验证负载均衡。
连续调用6次 http://localhost:9195/http/order/findById?id=95 GET 请求，可以在 soul-bootstrap:9195 console 打印如下日志：
可以看到 "The request urlPath is" 轮流调用 8188 和 8189 两个业务服务节点，因为 weight 都是50，调用比例为 1:1，结果就跟轮询调用一样。

4.2 数据同步
在 9095 修改权重，然后调用接口，查看是否按照修改后的权重发送请求：
8188 weight 30，8189 weight 60。
从日志中可以看到，调用1次8188，就会调用2次8189，符合预期比例 30:60=1:2。
