我收到以下错误:

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:/$ 

这是我尝试启动 mongodb 时发生的情况:

* Starting database mongodb                                             [fail]

我已经尝试过 mongo --repair

我为 var、lib、data/db 和 log mongodb 做了 chown 和 chmod。

不知道还能做什么。有什么建议吗？

mongodb.log:

编辑:

我删除了锁，然后做了 mongod repair 并得到了这个错误:

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

所以我用 sudo 做到了:

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

但还是有同样的问题。

最佳答案

Step 1: Remove lock file.
sudo rm /var/lib/mongodb/mongod.lock

Step 2: Repair mongodb. 
sudo mongod --repair 

Step 3: start mongodb.
sudo start mongodb 
or
sudo service mongodb start

Step 4: Check status of mongodb.
sudo status mongodb 
or   
sudo service mongodb status

Step 5: Start mongo console.
mongo
