如何连接运行在两个不同的AWS EC2实例上的pencilblue和mongodb？

Question

我让mongodb运行在一个ec2实例上，而pencilblue运行在另一个实例上。安装彭西兰之后，我使用命令pbctrl start启动服务器。然后，我得到以下错误

2016-04-25T20:35:12.100Z - error: [1] System[1]: uncaught Exception detected : Error: MongoError: connect ECONNREFUSED - mongodb://<private IP of mongodb EC2 inatnce>:27017/pencilblue?
Is your instance running?
    at /home/ubuntu/PencilBlue/pencilblue/include/dao/db_manager.js:113:31
    at /home/ubuntu/PencilBlue/pencilblue/node_modules/mongodb/lib/mongo_client.js:267:20
    at /home/ubuntu/PencilBlue/pencilblue/node_modules/mongodb/lib/db.js:218:14
    at null.<anonymous> (/home/ubuntu/PencilBlue/pencilblue/node_modules/mongodb/lib/server.js:226:9)
    at g (events.js:180:16)
    at emit (events.js:98:17)
    at null.<anonymous> (/home/ubuntu/PencilBlue/pencilblue/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:263:68)

    at null.<anonymous> (/home/ubuntu/PencilBlue/pencilblue/node_modules/mongodb/node_modules/mongodb-core/lib/connection/pool.js:77:12)

在pencilblue的config.js文件中，我提到了db详细信息，如下所示

"db": {
        "type": "mongo",
        "servers": [
            "mongodb://<private IP of mongodb EC2 inatnce>:27017/"
        ],
        "name": "pencilblue",
        "writeConcern": 1
    }

提前谢谢。

打开MongoDB服务器所在的安全组的端口27017，以允许来自PencilBlue服务器所在的安全组的访问。

还要确保您已经在您的bind_ip配置中更新了MongoDB设置，以便它将侦听本地主机之外的连接。
