以前有人问过这个问题，但从未回答过。此外，我的错误日志略有不同：

当我运行“mongo”时，出现此错误：

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

这是我的错误日志：

正如@Nilam 所说，您的问题之一是期刊，但是，您实际上在这里有两个问题，我所说的一个更像是一个警告：

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

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

您应该考虑增加 Linux 中的 openfile 计数，否则您可能会得到：http ://www.mongodb.org/display/DOCS/Too+Many+Open+Files当然，此页面还告诉您如何解决问题。

注意：作为日志点的旁注，看起来您的 MongoDB 节点可能正在尝试从某些东西中恢复。我会检查为什么。

与@Hartator 的回答类似，这为我解决了这个问题：

chmod -R 777 /data/db

你有

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

错误显示是

[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以及是否为该文件夹提供了适当的写入权限。

尝试运行：

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