我尝试使用这些说明在我的Ubuntu 16.04 LTS中安装mongodb：

当我试图运行命令时

从终端

Answer 1

注意做它说的话：

 Data directory /data/db not found

该目录不存在，那边MongoDB存储数据。你需要创建它：

mkdir -R /data/db

并确保用户已读取写入权限。

Answer 2

Mongo正在寻找默认数据目录/ data / db，它不存在。您可以创建/ data / db，也可以在您已拥有的文件夹中创建任何子文件夹。然后尝试

mongod --dbpath pathtosubfolder

启动服务器。然后在另一个终端启动客户端shell：

mongo

这应该有用。
