服務器說明
主機(nn): locator1 + server1
主機(db): locator2 + server2
主機(dn1): locator3 + server3
主機(dn2): locator4 + server4
分別在各主機創建Geode工作目錄，並在該目錄中進入GFSH命令行。

模擬locator崩潰
nn 模擬停機，kill所有geode相關進程 此時db機上的連接會自動斷開（推斷啓動locator時，會自動連至locators列表中第一臺啓動的locator），信息如下：
gfsh> No longer connected to nn[1099].
重新連接到db,如果沒有斷開連接就不用了
gfsh>connect --locator=db[10334]
