我刚刚按照here上的说明安装了mongodb。
当我尝试使用命令
启动mongodb时 sudo systemctl status mongodb
它转到下一个命令行，之后我运行命令
sudo systemctl status mongodb
我收到以下消息
mongodb.service - High-performance, schema-free document-oriented database
Loaded: loaded (/etc/systemd/system/mongodb.service; disabled; vendor preset: enabled)

请帮我解决这个问题。我尝试了很多东西，比如给予log和lib fies的许可。但对我来说没什么用。
提前致谢：）
