The following tutorials provide information in configuring replica set members to support specific operations, such as to provide dedicated backups, to support reporting, or to act as a cold standby.

以下教程为您介绍如何配置副本集成员以支持特定的操作，例如提供专用备份，支持报告或充当冷备用。

WARNING

警告

Avoid reconfiguring replica sets that contain members of different MongoDB versions as validation rules may differ across MongoDB versions.

由于不同的MongoDB版本所使用的验证规则可能有所不同，重新配置副本集时，应当避免该副本集包含不同版本的成员。
