在 Ubuntu 20.04 上安装 Mongodb 时出现问题

将提供快速背景信息。我严格遵守手册：https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

1. wget -qO -https://www.mongodb.org/static/pgp/server-4.4.asc| sudo apt-key 添加 -
2. echo "deb [ arch=amd64,arm64 ]https://repo.mongodb.org/apt/ubuntufocus/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
3. sudo apt-get 更新
4. sudo apt-get install -y mongodb-org
5. sudo systemctl 启动 mongod
6. sudo systemctl 状态 mongod

● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)

7. mongo

MongoDB shell version v4.4.1
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
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 :
connect@src/mongo/shell/mongo.js:374:17
@(connect):2:6
exception: connect failed
exiting with code 1

然后尝试使用以下命令修复此 status=14/n/a：

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

和其他东西

然后删除 mongodb：

sudo apt-get purge mongodb-org*
sudo apt remove mongodb
sudo apt purge mongodb
sudo apt autoremove

并以与上面相同的方式安装它，得到相同的结果。我需要帮助。

这就是etc/mongod.conf

# mongod.conf

#   http://docs.mongodb.org/manual/reference/configuration-options/

这是来自 var/log/mongodb/mongod.log 的 mongod 日志，该文件有 550 行，我只复制了最后一个日志：

更新 ATM 我这次尝试根据 stackoverflow 的指南再次重新安装：

1. sudo apt-get install --重新安装 mongodb （有错误 - 处理时遇到错误）
2. sudo systemctl 守护进程重新加载
3. sudo apt 更新/升级
4. sudo apt安装mongodb （以下软件包已自动安装，不再需要）
5. sudo apt 自动删除
6. sudo systemctl 状态 mongodb （主进程已退出，代码=已退出，状态=100/n/a）

8. sudo apt-get 安装 libc6 （libc6已经是最新版本（2.31-0ubuntu9.1））
9. sudo systemctl 状态 mongod

 mongod.service

ное 12 17:34:03 lubo systemd[1]: mongod.service: Current command vanished from the unit file, execution of the command list won't be resumed.

现在我相信我们已经工作了 mongodb，只需将它与 mongod.service 连接

首先删除 mongodb 的所有 PPA 存储库，然后：

sudo apt-get purge mongodb-org*
sudo apt remove mongodb
sudo apt purge mongodb
sudo apt autoremove
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-get install gnupg
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
sudo apt-get update
sudo apt-get upgrade
sudo apt update
sudo apt upgrade
sudo apt-get install -y mongodb-org
sudo apt-get install libc6
sudo service mongod start
sudo service mongod status

这帮助我解决了这个问题
