Question

此问题之前已被提出，但从未得到回答。此外，我的错误日志略有不同：

当我运行'mongo'时，我收到此错误：

MongoDB shell version: 2.2.0
connecting to: test
Fri Nov 16 10:52:05 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed

以下是我的错误日志：

感谢您的帮助！

Answer 1

正如@Nilam所说，你的一个问题是期刊，但是，你实际上在这里遇到两个问题，我所说的那个问题更多的是警告：

Fri Nov 16 10:47:44 [initandlisten] ** WARNING: soft rlimits too low. Number of files is 256, should be at least 1000

具体涉及：https://jira.mongodb.org/browse/SERVER-4407

你应该考虑在Linux中增加你的openfile数量，否则你可以得到这个：http://www.mongodb.org/display/DOCS/Too+Many+Open+Files当然这个页面也会告诉你如何解决这个问题。

注意：作为日志点的旁注，看起来你的MongoDB节点可能正试图从某些东西中恢复。我会检查原因。

Answer 2

与@ Hartator的答案类似，这解决了我的问题：

chmod -R 777 /data/db

Answer 3

你有

journal dir=/usr/local/var/mongodb/journal

错误显示为

[initandlisten] couldn't open /usr/local/var/mongodb/journal/lsn errno:13 Permission denied

因此，请检查日志目录是否存在，并为此文件夹指定了正确的写入权限。

Answer 4

尝试运行：

chmod 777 -R /usr/local/var/mongodb

Mongod运行，但Mongo返回错误
