運行“ mongod”時出錯

Question

我正在使用node.js和express.js制作應用程序。 當我運行mongo works時，當我嘗試運行mongod時出現此錯誤，並且沒有輸入localhost：28017

而不連接localhost：28017

Answer 1

您已經在端口28017上實例化了一個mongo實例。該錯誤表明該端口已在使用中。 您需要殺死任何正在運行的實例。

嘗試ps -ef | grep mongo查找mongo實例的pid。

默認端口mongo運行在27017。您也可以使用

lsof -n -i TCP | grep 27017獲取運行mongo的端口列表。
