node.js - Openshift 上部署的 Sails.js 项目的可视化错误

Question

我在 Openshift 上部署了我的 Sails 项目。 它可以工作，但我收到了 websockets 错误，并且无法加载基于 ejs 构建的页面。

我发现这些链接足以解释 grunt/openshift，但我无法解决问题。

Deploying Sails.js On Openshift

Deploy Sails.js on Openshift ... app restarting over and over

我的nodejs.log是:

这是我的 app.js:

require('sails').lift(require('optimist').argv);

这是我的 local.js:

module.exports = {
  host: process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1",
  port: process.env.OPENSHIFT_NODEJS_PORT || 8080,
  environment: process.env.NODE_ENV || 'development'
}

调用 'env | grep OPENSHIFT_NODEJS_PORT' 在 openshift 控制台上我收到:

OPENSHIFT_NODEJS_PORT=8080

在我看来，问题不在于端口。服务器启动并正确应答。 但是当我调用基于 ejs 构建的页面时，它会用一段 json 回答我...

{"view":{"name":"viewshows/index","root":"/var/lib/openshift/537b5ae8500446c95900057f/app-root/runtime/repo/views","defaultEngine":"ejs","ext":".ejs"}}

...并在服务器日志中打印上述错误。

有什么建议吗？

谢谢

我相当确定 openshift 要求您的应用程序监听由环境变量指定的特定端口，而不是 8080

您需要将 app.js 更改为使用此 openshift doc 中的主机名和端口环境变量。
