我在 Ubunutu 20.04 上全新安装了 MongDB 5.0，并且正在尝试配置基本根（管理员）用户访问控制根据文献当然，它在第一个命令上就不起作用。:-/
第一条指令说我需要mongod --port 27017 --dbpath /var/lib/mongodb以 mongodb 用户身份运行，在 Ubuntu 20.04 上默认情况下是mongdb
所以我已经运行了：
runuser -u mongodb -- "mongod --port 27017 --dbpath /var/lib/mongodb"（双引号）
-没有权限
runuser -u mongodb -- 'mongod --port 27017 --dbpath /var/lib/mongodb'（单引号）
-没有权限
runuser -u mongodb -- mongod --port 27017 --dbpath /var/lib/mongodb（无引号）
- 连接失败，输出如下：

关于我为什么会遇到上述失败，有什么想法吗？
更新：
凭着直觉，我运行了它chown mongodb:mongo /tmp/mongodb-27017.sock，从而解决了权限问题。
现在我得到：

已在使用的异常...嗯
答案1
对于像我一样只想保护您的 mongodb 管理员用户的其他完整 mongodb 新手，以便您可以实际遵循教程和课程，而不会让您的数据库被黑客入侵......这个答案适合您：
1.) 如果你无法通过运行以下命令获得与数据库的基本连接runuser -u mongodb -- mongod --port 27017 --dbpath /var/lib/mongodb
我上面的猜测是正确的，但不完整。您需要运行：
chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock
来源： https://stackoverflow.com/a/61323247/5180608
从那里运行systemctl restart mongod
现在您应该能够执行mongosh --port 27017连接到 mongodb，然后按照这些说明完成设置管理员用户和密码。
https://www.mongodb.com/docs/manual/tutorial/configure-scram-client-authentication/
如果您有连接问题，您可能需要编辑/etc/mongod.conf：
net:
port: 27017
bindIp: your-host-ip -OR- 127.0.0.1
从 5.0 bindIp 开始，必须是一个单一值。
