我已经尝试了所有可用的解决方案，但很不幸它们对我都不起作用。我正在使用Ubuntu 20.04

请按照@joe提供的链接中的说明进行操作，即可安装/升级MongoDB版本至4.4。 - vshenoy

Answer 1

只需在Ubuntu 20.04中运行以下命令：

sudo systemctl start mongod

然后运行：

mongod --fork --logpath /var/log/mongodb/mongodb.log --auth --port 27017 --dbpath /var/lib/mongodb

然后运行：

mongo

对我而言，它起作用了。

这对我没有起作用。我收到了错误消息 Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :。 - Rylan Schaeffer

Answer 2

请确保您已输入以下命令： sudo systemctl start mongodb 因为我在没有启动mongodb启动脚本的情况下检查了状态。

Answer 3

我在Ubuntu 21.10上安装MongoDB时遇到了问题，按照官方文档中的步骤操作后，出现了与原帖作者相同的错误。以下步骤适用于我（需要重新启动）

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10</span>

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

sudo apt-get update

sudo apt-get install -y mongodb-org

sudo apt-get install -y mongodb-org=3.4 mongodb-org-server=3.4 mongodb-org-shell=3.4 mongodb-org-mongos=3.4 mongodb-org-tools=3.4

然后用编辑器打开以下内容（在这个例子中使用VIM - 使用 :wq 写入并退出）

sudo vim /etc/systemd/system/mongodb.service

粘贴：

#Unit contains the dependencies to be satisfied before the service is started.
[Unit]
Description=MongoDB Database
After=network.target
Documentation=https://docs.mongodb.org/manual
# Service tells systemd, how the service should be started.
# Key `User` specifies that the server will run under the mongodb user and
# `ExecStart` defines the startup command for MongoDB server.
[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
# Install tells systemd when the service should be automatically started.
# `multi-user.target` means the server will be automatically started during boot.
[Install]
WantedBy=multi-user.target

然后继续重新加载和启动...

systemctl daemon-reload

sudo systemctl start mongodb

在所有这些操作之后，您可能只需要重新启动一下... 您可以使用以下命令来检查状态并启用：

sudo systemctl status mongodb
sudo systemctl enable mongodb
