当我尝试运行命令mongo
时出现此错误:
MongoDB shell version v4.0.0
connecting to: mongodb://127.0.0.1:27017
2018-07-24T13:08:13.968+0800 E QUERY [js] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:251:13
@(connect):1:6
exception: connect failed
运行此命令sudo service mongod status
后,它会向我输出如下内容:
mongod.service - MongoDB Database Server

从终端运行时,数据文件是在root而不是mongodb用户下创建的。
您需要授予权限:
cd /var/lib/mongodb
sudo chown -R mongodb:mongodb *
希望这会有所帮助。

我遇到了同样的错误,可能是因为 ubuntu 从 18.04 升级到 20.04。无法手动启动 mongod
,原因是没有 /data/db
及其权限。然后 mongod
将手动启动,但在 mongodb.service
上仍然出错。最后重新安装 mongodb 工作。这是一个新安装,所以不关心备份。
$ sudo apt remove mongodb mongo-tools mongodb-clients mongodb-server mongodb-server-core
$ sudo apt autoremove
$ sudo rm -rf /var/lib/mongodb/
$ sudo apt install mongodb
