在我的 ubuntu 22.04 上尝试安装 mongodb-org 几次，并按照许多 youtube 视频以及文档教程进行操作，但安装失败。

运行mongod显示上述内容并检查状态显示

正在播放的mongo节目：

答案1
使用 systemctl 而不是 service。安装后删除 sock 文件
sudo rm -rf /var/lib/mongodb-27017.sock
然后使用 systemctl 重新启动 mongodb，因为它在最新的 Ubuntu 版本甚至 Ubuntu 旧版本（如 20.04 LTS）中使用 SystemD
sudo systemctl 启动 mongod
使用服务运行导致错误
