Question

我正在尝试通过以下链接创建一个包含3台计算机的mongodb群集：http://docs.mongodb.org/manual/tutorial/deploy-shard-cluster/。我已将mongodb 2.6.4下载到所有计算机并使用此命令启动配置服务器：

 mongod --configsvr --dbpath /home/sshusr/mongodb/data/configdb/

我正在尝试启动mongos实例将配置服务器升级到v5，因为它告诉我这样做。所以我运行这个命令

mongos --upgrade --configdb 10.122.123.64:27019,10.122.123.65:27019,10.122.123.66:27019

但它给了我这个

我在这里想念的是什么？任何帮助表示赞赏。感谢。

我已经解决了这个问题。

我用详细执行命令，发现服务器之间存在时间/日期差异。我为每个服务器分配了一个ntp服务器，问题解决了。
