macos - 无法连接到 MongoDB 错误 :61

Question

我使用 macports 安装了 MongoDB，并尝试运行 mongo 命令以启动 mongo shell。我收到以下错误:

warning: Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused

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

然后我运行 mongod 并收到以下错误:

$ [initandlisten] MongoDB starting : pid=11984 port=27017 dbpath=/data/db 64-bit host=Nikitas-MacBook-Air.local
$ [initandlisten]

在哪里可以在根目录下创建 /data/db 目录？当我运行 mongo 时，第二个错误会是 errno:61 的原因吗？

Answer 1

我遇到了类似的问题。我已经详细的错误跟踪和解决方案on this blog这是我为解决此问题所做的逐步过程:

第 1 步 - 安装(如果您已经安装了 MongoDB，请不要执行此步骤):

brew update
brew install mongodb

第 2 步 - 运行 Mongo 守护进程:

mkdir -p /data/db
sudo mongod

第 3 步 - 运行 Mongo Shell 界面:

mongo

在这个序列中，我能够运行 mongo 命令而没有任何错误。
