使用MySQL数据源将Strongloop/Loopback部署到Openshift时出错

我一直在尝试使用MySQL数据源应用程序将Strongloop/Loopback部署到Openshift，但没有成功。以下是我遵循的步骤

已在我的Windows 7上安装节点

npm是否安装了-g strongloop

创建了一个数据源，遵循此

我没有使用MongoDB，而是使用MySQL。下面是我的设置

package.json

{
  "name": "loopback-app",
  "version": "0.0.0",
  "main": "server/server.js",
  "scripts": {
    "start": "slc run",
    "pretest": "jshint ."
  },
  "dependencies": {
    "compression": "^1.0.3",
    "errorhandler": "^1.1.1",
    "loopback": "^2.0.0",
    "loopback-boot": "^2.0.0",
    "loopback-connector-mysql": "^2.1.1",
    "loopback-datasource-juggler": "^2.0.0",
    "serve-favicon": "^2.0.1"
  },
  "optionalDependencies": {
    "loopback-explorer": "^1.1.0"
  }
}

datasources.json

{
  "db": {
    "name": "db",
    "connector": "memory"
  },
  "mysql": {
    "host": "mysql-openshift-db-host",
    "port": mysql-openshift-db-port,
    "database": "gearname",
    "password": "mysql-password",
    "name": "mysql",
    "connector": "mysql",
    "user": "mysql-username"
  }
}

model-config.json

{
  "_meta": {
    "sources": [
      "../common/models",
      "./models"
    ]
  },
  "User": {
    "dataSource": "db"
  },
  "AccessToken": {
    "dataSource": "db",
    "public": false
  },
  "ACL": {
    "dataSource": "db",
    "public": false
  },
  "RoleMapping": {
    "dataSource": "db",
    "public": false
  },
  "Role": {
    "dataSource": "db",
    "public": false
  },
  "Demo": {
    "dataSource": "mysql",
    "public": true
  }
}

当在我的机器上本地运行它时，它会工作。但是，在将其部署到Openshift然后转到http:///explorer 并为我的模型尝试其中一种方法

==>strongloop/logs/node.log app root/logs/haproxy.log您的应用程序需要监听您的openshift ip地址和端口，似乎它仍在尝试监听localhost:3000。在代码中，您还应该确保使用mysql环境变量连接到mysql。以下是一些您应该通读的参考资料：


您能清理节点模块并确保安装了最新的DEP吗？我修改了config.json文件，更改了主机和端口，并使用了“mycloud mydomain.rhcloud.com”和端口80。至于mysql设置，我相信我的设置是正确的，因为我使用的是openshift中env的设置。然而，它仍然抛出相同的错误。还补充说，我使用Strongloop盒带在Openshift中安装了Strongloop。我似乎没有定义一些节点变量。不确定这是否相关。您应该使用端口8080和openshift ip地址（openshift_NODEJS_ip），而不是您的cnameI似乎没有env openshift_NODEJS_ip。我使用Strongloop创建了应用程序。不知何故，节点相关变量没有设置。另外，我要指出的是，我可以打开，我可以看到我创建的用户和演示。只有当我单击自定义模型的其中一个方法时，我才会得到错误。
