当我在ubuntu的mongo终端中运行show dbs时，命令没有运行

Question

When running the following command:

mongos --configdb 10.8.15.175:27019,10.8.14.89:27019,10.8.9.100:27019

I get this error:

FailedToParse: mirrored config server connections are not supported; for config server replica sets be sure to use the replica set connection string

Can you help me figure out what's wrong?

Answer 1

I imagine you are running MongoDB 3.4 binaries here? From version 2.2 MongoDB added support for configuration servers to run as a replica set (whereas they used to be a special set of nodes that synced via another mechanism). In 3.4, it became required to use replica sets. In this situation you need to specify the name of the replica set of the config, as per @Josh's post:

<config replset name>/<host1:port>,<host2:port>,[...]

Answer 2

用于与配置服务器通信的连接字符串： <config replset name>/<host1:port>,<host2:port>,[...]
