如何在 Ubuntu 16 上设置 Mongodb？

Question

我尝试使用这些指令在我的 Ubuntu 16.04 LTS 中安装 mongodb：

当我尝试运行命令时

Answer 1

注意言出必行：

 Data directory /data/db not found

那个目录不存在，MongoDB那边存放着数据。您需要创建它：

mkdir -R /data/db

并确保用户具有读写权限。

Answer 2

Mongo 正在查找不存在的默认数据目录 /data/db。您可以创建 /data/db 或实际上在您已经拥有的文件夹中创建任何子文件夹。然后试试

mongod --dbpath pathtosubfolder

启动服务器。然后在不同的终端启动客户端 shell:

mongo

这应该有效。
