mongodb常遇到的错误解决
mongodb常遇到的错误解决在运行mongos命令时出现如下类似错误config servers localhost:27017 and localhost:12000 differconfig servers localhost:27017 and localhost:12000 differconfigservers localhost:27017 and localhost:12000 differconfig servers localhost:27017 and localhost:12000 differconfig servers not in sync! config servers localhost:27017 and localhost:12000 differchunks: "d41d8cd98f00b204e9800998ecf8427e" EOOdatabases: "0195c739c938fdafd9632279694ea64e" EOOWed Oct 09 15:36:42 [mongosMain] configServer connection startup check failed说明你第一次实验参与集群的mongod服务与当前参与集群的mongod服务数量不一致。解决方法是把第一次参与集群的mongod 数据目录下所有的config.0，config.1，config.ns 删除。重新启动mongos即可。
