如果我尝试运行 mongoid --repair

我会得到同样的错误

Answer 1

1) 创建文件夹/data/db，然后通过命令启动服务器

./mongod

如果需要写入权限，则使用

sudo ./mongod

2) 如果要使用自定义路径，则在任意位置创建文件夹。然后你可以通过下面的命令启动服务器

在 Linux 中，假设创建的文件夹是“/home/mongo/db”

./mongod --bpath /home/mongo/db

在 Windows 中，假设创建的文件夹是 'd:\mongodb\data'

C:\mongodb\bin\mongod.exe --dbpath d:\mongodb\data

无法启动mongod
