ICE Grid 入門篇
這篇是ICE Grid入門的最簡單版本(不涉及到IceGride Node)。這里面設計到過多的概念和知識，暫且不表。
創建slice文件

10 interface Printer {
11 void printString(string s);
12 };
13 };
轉換slice
slice2cpp Printer.ice
配置IceGrid Registry
registry.cfg
IceGrid.InstanceName=DemoGrid
Ice.Default.Locator=DemoGrid/Locator:default -p 4061
IceGrid.Registry.Client.Endpoints=tcp -p 4061
IceGrid.Registry.Server.Endpoints=tcp
IceGrid.Registry.Internal.Endpoints=tcp
IceGrid.Registry.PermissionsVerifier=DemoGrid/NullPermissionsVerifier
IceGrid.Registry.AdminPermissionsVerifier=DemoGrid/NullPermissionsVerifier
IceGrid.Registry.SSLPermissionsVerifier=DemoGrid/NullSSLPermissionsVerifier
IceGrid.Registry.AdminSSLPermissionsVerifier=DemoGrid/NullSSLPermissionsVerifier
IceGrid.Registry.Data=./data
IceGrid.Registry.DynamicRegistration=1
啟動Registry
icegridregistry --Ice.Config=./registry.cfg &
啟動前最好創建數據目錄./data
mkdir ./data
