MongoDB2.6启动失败

Question

我正在尝试运行MongoDB2.6，所有内容都遵循我的2.4版本设置步骤。但是，当我开始蒙哥斯，我有以下问题，只是无法做到。

2014-04-24T03:38:31.001+0800 [mongosMain] SyncClusterConnection connecting to [192.168.0.1:27018]

等待新格式的v5？那是什么？

Answer 1

有一个用于2.6升级的全套指令，但您似乎没有注意到您已经遵循了它。

特别是指示您需要通过在关闭平衡器时启动单个-升级实例来处理mongos选项的说明：

使用指向集群的配置服务器的configDB和-升级选项启动一个2.6mongos实例。若要使用--升级选项运行mongos，可以将现有的mongos实例升级到2.6，或者如果需要避免重新配置生产mongos实例，则可以使用新的2.6 mongos，它可以到达所有配置服务器。

mongos --configdb <config servers> --upgrade

如上文所述，完成后应发出以下信息：

upgrade of config server to v5 successful
Config database is at version v5

因此，配置服务器有一个预期的升级过程，您可能还没有遵循这个过程。整个过程在这个答案顶部的链接中。

还请看一看兼容性变化列表，其中有一些可能适用于您的情况的副本集和切分的附加注意事项。
