服务器说明
主机(nn): locator1 + server1
主机(db): locator2 + server2
主机(dn1): locator3 + server3
主机(dn2): locator4 + server4
分别在各主机创建Geode工作目录，并在该目录中进入GFSH命令行。

模拟locator崩溃
nn 模拟停机，kill所有geode相关进程 此时db机上的连接会自动断开（推断启动locator时，会自动连至locators列表中第一台启动的locator），信息如下：
gfsh> No longer connected to nn[1099].
重新连接到db,如果没有断开连接就不用了
gfsh>connect --locator=db[10334]
