Question

我使用以下命令安装了MongoDB：

sudo apt update
sudo apt install mongodb

以及当我检查服务状态时：

mongodb.service - An object/document-oriented database
   Loaded: loaded (/lib/systemd/system/mongodb.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Wed 2019-11-06 10:25:11 PST; 54min ago
     Docs: man:mongod(1)
  Process: 1030 ExecStart=/usr/bin/mongod --unixSocketPrefix=${SOCKETPATH} --config ${CONF} $DAEMON_OPTS (code=exited, status=100)
 Main PID: 1030 (code=exited, status=100)

Nov 06 10:25:09 JDL systemd[1]: Started An object/document-oriented database.
Nov 06 10:25:11 JDL systemd[1]: mongodb.service: Main process exited, code=exited, status=100/n/a
Nov 06 10:25:11 JDL systemd[1]: mongodb.service: Failed with result 'exit-code'.

我尝试创建/data/db并更改了其权限。我还能够运行mongod命令，甚至重新启动PC。我还尝试删除lock文件，并在MongoDB中做了repair，但结果仍然相同。

如何解决此问题？我试图寻找解决方案，但似乎没有一个适合我。

运行sudo tail -n 20 /var/log/mongodb/mongod.log向我展示了

如果不需要数据库，请使用rm -rf /usr/lib/mongodb删除数据库文件夹中的所有文件（在Ubuntu路径中为/ usr / lib / mongodb），如果需要数据库，请按照以下步骤操作：当您将MongoDB Server升级时，可以说是从3.4升级到3.6。升级之前，还需要使用此命令设置数据库功能兼容版本。此命令必须在MongoDB Server v3.4中运行

db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )

，然后升级到下一个主要版本。例如，您必须将MongoDB服务器从3.4升级到3.6，而不是直接升级到4.0 有关更多详细信息，请遵循MongoDB Docs
