Question

我在ubuntu 16.04上使用：

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有效时，请帮助我。我不知道自己该做什么！

我之前曾在c9上工作但它有很多问题并且很慢，我需要mongodb来处理我的项目（抱歉我的坏人）

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。似乎这条道路不存在。

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。

Answer 2

如果mongodbversion> = 4并安装在ubuntu中，请使用mongod代替mongod b

sudo systemctl status mongod sudo systemctl启动mongod 须藤vi /etc/mongod.conf

否则，mongodb命令将出现以下错误

无法重新启动mongodb.service：单元mongodb.service被屏蔽。

MongoDB不是从ubuntu 16.04开始的
