没有访问控制无法启动mongodb

Question

我正在使用 EC2（适用于 Ubuntu 16.04）并且我已经安装了 mongodb 3.6 但是当我使用以下命令启动它时

mongod --port 27017 --dbpath /data/db

出现以下错误

An unsupported journal format detected - If you are trying to rollback from version 4.0 to 3.6, please re-start a 4.0 binary and cleanly shut it down so that the journal format will be downgraded.

Assertion: 28595:13: Permission denied src/mongo/db/storage/wiredtiger/wiredtiger_kv_engine.cpp 488

exception in initAndListen: Location28595: 13: Permission denied, terminating

Invariant failure globalStorageEngine src/mongo/db/service_context_d.cpp 272

请推荐

试试：

sudo service mongod restart
sudo service mongod status

sudo service mongod stop
sudo service mongod status

然后也许你要遵循的命令
