为什么 couchdb 寻找“_users”数据库？

Question

CouchDB 日志中的此错误意味着什么？我看到它正在寻找一些“_users”数据库。但我没有同名的数据库。我能做些什么来阻止这些错误吗？

我在 Couchdb 文档中找到了解决方案

https://docs.couchdb.org/en/latest/setup/single-node.html

确保在启动时手动创建三个系统数据库：

卷曲-X PUT http://127.0.0.1:5984/_users

卷曲-X PUT http://127.0.0.1:5984/_replicator

卷曲-X PUT http://127.0.0.1:5984/_global_changes

请注意，如果您不希望使用全局更改源，则不需要最后一个。如果您已经创建了该数据库，并且它的大小已经增大，并且您不需要该功能（并且不希望在定期压缩它时浪费系统资源），请随意删除该数据库。
