ice grid 入门篇
这篇是ice grid入门的最简单版本(不涉及到icegride node)。这里面设计到过多的概念和知识，暂且不表。
创建slice文件

9 module demo{
10 interface printer {
11 void printstring(string s);
12 };
13 };
转换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
启动registry
icegridregistry --ice.config=./registry.cfg &
启动前最好创建数据目录./data
mkdir ./data
服务端
