安装后 MongoDB 4.2 无法在 ubuntu 18.04 上启动 - 进程立即停止

Question

我对 mongoDB 有疑问 - 我按照官方教程一步一步来:
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

我也是通过这个答案安装的(当然我改变了一些命令来下载 4.2 而不是 4.0，就像在这个答案中一样):https://askubuntu.com/questions/842592/apt-get-fails-on-16-04-or-18-04-installing-mongodb/842599#842599

但毕竟它仍然不起作用:

adrian@ubuntu:~$ sudo service mongod start
adrian@ubuntu:~$ sudo service mongod status
● mongod.service - MongoDB Database Server
   Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)

Sep 26 09:37:53 ubuntu systemd[1]: mongod.service: Failed with result 'exit-code'.

即使我尝试调查 mongo 日志，它仍然没有告诉我太多:

我将非常感谢任何建议

从您的 ubuntu 中删除完整的 mongodb

sudo apt-get purge mongo* // or sudo apt remove mongo*
sudo apt-get purge mongodb-org*

备份数据库并使用文件夹删除日志和数据

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb

现在用这个再次安装

$ wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc \
  sudo apt-key add -

添加来源

$ echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse" \
  sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

然后再次安装mongodb包

sudo apt-get install -y mongodb-org=4.2.0 \
                        mongodb-org-server=4.2.0 \
                        mongodb-org-shell=4.2.0 \
                        mongodb-org-mongos=4.2.0 \
                        mongodb-org-tools=4.2.0

使用 mongodb 启动服务

$ systemctl enable mongod.service

$ sudo service mongod start
