Mongodb Mongod在ubuntu 16.04上崩溃

我正在开发一个由mongodb支持的应用程序。无论是从shell还是从应用程序以编程方式与db服务器交互，都可以正常工作。问题是，只有当我以root用户身份运行服务器时，它才能工作。否则就不行了。在windows上工作时，我没有这个问题。我使用的是ubuntu 16.04

首先，是db路径，我更改了配置文件。然后它告诉我它无法创建锁文件，我更改了权限（我不确定这是否是一个好的做法），现在我出现了以下错误：

Detected data files in /data/db created by the 'wiredTiger' storage engine, so setting the active storage engine to 'wiredTiger'.

另外，当我尝试将其作为服务运行时，

service mongod start

，它会抛出一个错误，即没有这样的服务文件。我在/etc/systemd/system目录中创建了一个mongod.service文件，但它仍然给出相同的错误，没有这样的文件

以下是

systemctl status mongod

的结果：

我也有同样的问题

sudo systemctl start mongod

在我的环境中似乎不起作用

试试

sudo服务mongod start

它解决了我这边的问题

使用sudo systemctl status mongod

给我
