Question

当我将我的环境从本地（mac）移动到我的服务器（ubuntu）时，我解压缩了我的目录和安装了npm install的服务器没有错误或警告，但是我的数据库失败了所以我决定根据本教程重新安装它（好吧） ，apt-remove mongo*第一）

但后来我得到了

Job for mongodb.service failed because the control process exited with error code. See "systemctl status mongodb.service" and "journalctl -xe" for details.

有谁知道这意味着什么？

基本上所有那些文件列在你的/etc/mongod.conf

运行以下命令，它适用于我

sudo apt-get install --reinstall mongodb
