无法连接到服务器 127.0.0.1:27017

all

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]

我已经试过了mongo --repair

我将 chown 和 chmod 设置为 var、lib 和 data/db 并记录 mongodb。

不知道还能做什么。有什么建议么?

mongodb.log:

***** SERVER RESTARTED *****

编辑:

我删除了锁,然后进行了 mongod 修复并得到了这个错误:

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

但仍然有同样的问题。

日志表明 mongodb 正在终止,因为有一个旧的锁文件。

如果您没有并且没有运行日志,请删除锁定文件,运行修复,然后再次启动 mongodb。

如果您正在或曾经在打开日志的情况下运行,请参阅相关的 Mongo DB
文档
。请注意,他们说“如果您使用日记功能运行,则不应进行修复以恢复到一致的状态。”
所以如果你在写日记,修理可能会让事情变得更糟。
