mongod我遇到一个问题，下载 MongoDB 后无法使用 cmd 连接到 MongoDB 服务器。
这是使用时终端显示的内容mongod：

我尝试过多次卸载/清除并重新安装 MongoDB。在完成以下操作后，我能够连接...
正在卸载 MongoDB...
sudo service mongod stop
sudo apt-get purge mongodb-org*
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev
sudo apt-get purge mongodb-10gen
sudo apt-get autoremove
正在卸载指南针...
sudo dpkg --remove mongodb-compass
然后我转到 MongoDB 文档进行安装：“Ubuntu 版 MongodDB 社区版”，具体来说是 20.0.04 LTS（“Focal”）......我已经
nick@777:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
我根据文档执行以下操作......
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org

使用以下方法验证 mongod 版本mongod --version
db version v5.0.4
Build Info: {
"version": "5.0.4",
"gitVersion": "62a84ede3cc9a334e8bc82160714df71e7d3a29e",
"openSSLVersion": "OpenSSL 1.1.1f 31 Mar 2020",
"modules": [],
"allocator": "tcmalloc",
"environment": {
"distmod": "ubuntu2004",
"distarch": "x86_64",
"target_arch": "x86_64"
}
}
我在使用以下方法检查状态时也得到了此输出sudo systemctl status mongod
sudo systemctl status mongod
● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Mon 2021-11-29 20:24:04 PST; 5s ago

Nov 29 20:24:04 Lufarius777 systemd[1]: mongod.service: Failed with result 'exit-code'.
我真的不知道终端是否显示了该命令的正确输出mongod
我还尝试使用以下命令停止/重新启动该服务
sudo systemctl stop mongod
sudo systemctl restart mongod
任何帮助都将非常有助于结束这场噩梦，谢谢！
答案1
在根目录（计算机文件夹）中创建目录 /data/db。然后使用以下命令启动 MongoDBsudo mongod
希望这可以帮助
