Question

我使用以下方法安装了mongodb：http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

当我运行mongod时，我明白了：

mongod --help for help and startup options

当我输入mongo时，我明白了：

MongoDB shell version: 2.2.3
connecting to: test
Fri Mar  1 18:13:00 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed

当我浏览localhost：3000时，我明白了：

Moped::Errors::ConnectionFailure in MembersController#lawlab

Could not connect to any secondary or primary nodes for replica set <Moped::Cluster nodes=[<Moped::Node resolved_address="127.0.0.1:27017">]>

我在这里缺少什么？

Answer 1

应该创建data / db /文件夹并授予用户访问该文件夹的权限。

Answer 2

为清楚起见：创建data / db文件夹与/ data / db之间存在差异。一个安装在根目录中，一个不是。因此，您应该创建/ data / db /文件夹，然后使用sudo chown -R / data / db /

来访问该文件夹

运行mongod时出错
