Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js

mongdb啟動的時候會報如上標題的錯誤，查詢了很多資料終於找到解決辦法，現把解決方法記錄下來，以免以後忘記。
[[email protected] bin]# ./mongo 但是出現如下錯誤： [[email protected] bin]# ./mongo MongoDB shell version: 2.6.1 connecting to: test 2014-05-30T19:58:07.179+0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused 2014-05-30T19:58:07.181+0800 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146 exception: connect failed
1、若資料庫出現如上不能連線的原因，可能是data目錄下的mongod.lock檔案問題，可以用如下命令修復：
[[email protected] mongodb]# ./bin/mongod --repair或者直接刪除mongod.lock
rm -f /usr/local/mongodb/data/db/mongod.lock然後再啟動mongodb。
2、如果第一步解決不了，那麼就是路徑設定有問題，通過重新對路徑的設定解決此問題
[[email protected] mongodb]# ./bin/mongod --dbpath=/usr/local/mongodb/data/db/然後介面會出現：

表示設定成功，此時不要關閉這個介面，需要重新開啟一個視窗來啟動mongo
[[email protected]]# cd /usr/local/mongodb
[[email protected] mongodb]# ./bin/mongo
