Mongod運行，但Mongo返回一個錯誤

這個問題之前已經問過，但從未回答過。此外，我的錯誤日誌略有不同：Mongod運行，但Mongo返回一個錯誤

當我運行「蒙哥」我得到這個錯誤：

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

這裏是我的錯誤日誌：

感謝您的幫助！

怪異...它工作時，我在一個選項卡，然後打開運行的mongod第二個標籤並運行mongo客戶端。爲什麼會這樣？ – brianabelson

你有

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

錯誤顯示爲

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

所以檢查日誌目錄中存在和適當的寫權限被賦予到這個文件夾。

嗨尼拉姆，謝謝你的迴應。這個文件夾一切都應該沒問題。這裏的權限：'-rwxrwxrwx 1 root admin 88 Sep 29 10:38 lsn' – brianabelson

你是以root/admin身份運行MongoDB嗎？如果你從回購站安裝，很可能用戶實際上是'mongod'或'mongodb'，我會檢查你運行mongod的用戶，我們也不知道你是以服務方式運行還是直接運行命令提示符，哪種方式運行？ – Sammaye

由於@Nilam說你的問題之一是該雜誌，但是，你實際上有兩個問題在這裏，我說的是更多的警告的一個：

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

這具體涉及到：https://jira.mongodb.org/browse/SERVER-4407

你應該考慮在Linux中增加你的openfile數量，否則你可以得到這個：http://www.mongodb.org/display/DOCS/Too+Many+Open+Files當然這個頁面也告訴你如何解決這個問題。

注意：作爲日記點的旁註，它看起來像您的MongoDB節點可能試圖從某些東西中恢復。我會檢查爲什麼。

-2

嘗試運行：

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

我得到：「沒有這樣的文件或目錄」 – brianabelson

雖然我naviagate到其中包含的文件夾：雜誌\t \t mongod.lock \t test.0 \t \t test.1 \t \t test.ns – brianabelson

類似@ Hartator的答案，這解決了我的問題：

chmod -R 777 /data/db
