[mongodb] 서버 127.0.0.1:27017에 연결할 수 없습니다

다음과 같은 오류가 발생합니다.

alex@alex-K43U:/$ mongo
MongoDB shell version: 2.2.0
connecting to: test
Thu Oct 11 11:46:53 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed
alex@alex-K43U:/$ 

이것은 mongodb를 시작하려고 할 때 발생합니다.

* Starting database mongodb                                             [fail]

나는 이미 시도했다 mongo --repair

chown 및 chmod를 var, lib 및 data / db에 만들고 mongodb를 기록했습니다 .

무엇을해야할지 모르겠습니다. 어떤 제안?

편집하다:

자물쇠를 제거한 다음 mongod repair를 수행 하고이 오류가 발생했습니다.

Thu Oct 11 12:05:37 [initandlisten] exception in initAndListen: 10309 Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating

그래서 sudo로했습니다.

alex@alex-K43U:~$ sudo mongod --repair

그러나 여전히 같은 문제가 있습니다.

mongo 

~$ sudo service mongodb stop

~$ sudo rm /var/lib/mongodb/mongod.lock

~$ sudo mongod --repair --dbpath /var/lib/mongodb

~$ sudo mongod --fork --logpath /var/lib/mongodb/mongodb.log --dbpath /var/lib/mongodb

~$ sudo service mongodb start
