【问题描述】：
在使用 MEAN.js 创建我的应用程序时，无法以任何方式在端口 27017 上进行 mongodb 连接。 我在目录中手动安装了 mongodb
~$ ls -la /etc/init.d/mongod
输出
lrwxrwxrwx 1 root root 56 Nov 4 20:45 /etc/init.d/mongod -> /home/myuser/projects/packages/linux-mongodb/bin/mongod
I try to run the file or `` server.js` grunt` the NASC repository command and got the following error:
运行node server.js 我收到这个输出：
Application loaded using the "development" environment configuration
Failed to load c ++ bson extension, using pure JS version
Insecurely using http protocol
MEAN.JS application started on port 27017
Could not connect to MongoDB!
Error: connection closed

编辑
我不再使用 MEAN.js，但我继续学习 MongoDB 和 node.js
问题是我不知道如何启动mongodb连接数据库
这一年我学到了很多关于 mongodb 和 node.js 的知识，我明白了我需要做什么。
在您的帮助下，我完成了三个步骤：
- 使用
mongod --dbpath /project/path-do-database/打开控制台 - 我将 API 连接到 mongodb，并通过了正确的端口
- 通过使用
node或nodemon启动node.js API 并传递项目的主javascript 文件来打开第二个控制台。
【问题讨论】：
-
你能粘贴你的完整错误吗？
-
mongod 还在运行吗？尝试使用 CLI 客户端
mongo连接并检查 netstat 绑定到哪个 IP 和端口。 -
谢谢@mnemosyn！你的帮助对我很有帮助。
