MongoDB 未从 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

但是当我检查状态为活动时，请帮助我。我不知道我必须做什么！

我以前用过 c9，但它有很多问题而且速度很慢，我需要 mongodb 来处理我的项目（抱歉我的英语不好）

Answer 1

错误消息中某处显示 "dbpath (/data/db) does not exist"。 “/data/db”是 mongodb 存储其数据文件的默认目录。您必须手动创建它。这条路好像不存在

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 mongodb版本 >=4 并且安装在 ubuntu，请使用 mongod 而不是 mongodb

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

否则，mongodb 命令

会出现以下错误

Failed to restart mongodb.service: Unit mongodb.service is masked.

MongoDB 未从 ubuntu 16.04 开始

MongoDB isn't starting in ubuntu 16.04
