由于制裁问题，我通过更改 DNS 安装了 Mongodb。现在，我已经安装了 mongodb，但是当我在 Ubuntu 终端中输入“mongod”时，我得到了以下信息：

然后，当我使用命令“sudo mongod”重新运行它时，我遇到：

当我输入“sudo systemctl status mongodb”时，我得到了这个：
Unit mongodb.service could not be found.
但是，当我输入此命令时，我得到了正确的答案：“mongo --eval'db.runCommand({connectionStatus: 1})'”
MongoDB shell version v4.2.5
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("a24c786b-d161-4c3c-91bd-a55198d72505") }
MongoDB server version: 4.2.5
{
"authInfo" : {
"authenticatedUsers" : [ ],
"authenticatedUserRoles" : [ ]
},
"ok" : 1
}
现在，我想知道问题可能是什么？
