Answer 1

正确的答案应该是这样的。

以下是我尝试从Ubunut上的命令行启动mongodb的情况。它显示以下错误，如上所述

error couldn't remove journal file during shutdown assertion 
src/mongo/db/dur_journal.cpp:235

然后我如何修复

我使用` tail -f /var/log/mongodb/mongodb.log
使用mongod --dbpath

mongod --dbpath home/test/data/mymogodb/

打开一个新的终端窗口并使用 mongos 进行连接，如下所示 mongos和press Enter

干杯！您 mongodb 现在已连接并且可以运行您的所有命令！

Answer 2

您必须先启动mongod实例才能连接它。

在您的终端类型“mongod＆amp;”启动数据库。然后你可以使用mongo shell连接它。

在Mac上的localhost上连接到MongoDB时出错
