MongoDB 没有从 ubuntu 16.04 开始

Question

我在 ubuntu 16.04 上设置了 mongodb:

echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org

但是当我尝试启动服务时出现这些错误:

**~$** systemctl start mongodb
Failed to start mongodb.service: Unit mongodb.service is masked.

**~$** systemctl start mongod
Failed to start mongod.service: Unit mongod.service not found.

**~$** sudo service mongod start
Failed to start mongod.service: Unit mongod.service not found.

**~$** mongod
mongod --help for help and startup options

但是当我检查状态是否处于事件状态时，请帮助我。我不知道我该怎么办!

我以前在 c9 上工作过，但它有很多问题而且速度很慢，我需要 mongodb 来处理我的项目
(对不起我的英语不好)

Answer 1

错误消息中的某处显示“dbpath (/data/db) 不存在”。 “/data/db”是 mongodb 存储其数据文件的默认目录。您必须手动创建它。这条路似乎不存在。

如果要更改此路径，请将 --dbpath 参数传递给 mongod 或更改 mongodb.conf 文件中的 dbpath 参数值。
