应用程序无法启动(端口8080)不可用
我正在尝试将我的node.js应用程序(带有express和mongoose)部署到openshift上,但我无法这样做。该应用程序可以在我的本地环境中完美运行。
我的入口是文件/ bin / www
我将它作为package.json文件中此行的openshift入口点
"main": "bin/www",
我已经确保按照指南使用环境变量设置mongodb连接,如下所示:
// default to a localhost configuration:var mongoConnectionString = 'mongodb://127.0.0.1/code-blog';
// if OPENSHIFT env variables are present, use the available connection info:
if (process.env.OPENSHIFT_MONGODB_DB_PASSWORD) {
mongoConnectionString = process.env.OPENSHIFT_MONGODB_DB_USERNAME + ":" +
process.env.OPENSHIFT_MONGODB_DB_PASSWORD + "@" +
process.env.OPENSHIFT_MONGODB_DB_HOST + ':' +
process.env.OPENSHIFT_MONGODB_DB_PORT + '/' +
process.env.OPENSHIFT_APP_NAME;
}
mongoose.connect(mongoConnectionString);
我得到的错误是:
remote: Waiting for application port (8080) become available ...remote: Application 'codeblog' failed to start (port 8080 not available)
remote: -------------------------
remote: Git Post-Receive Result: failure

这对我来说很奇怪,因为我没有在任何地方指定端口8080。实际上,默认端口在此处指定:
var port = normalizePort(process.env.OPENSHIFT_NODEJS_PORT || "3000");var server_ip_address = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
app.set('port', port);
var server = http.createServer(app);
我不太确定从这里到哪里。我似乎没有足够的信息来确定下一步。
[edit]我添加了一些日志记录以测试该端口在哪个端口上运行,但是该日志记录语句永远不会运行。这是代码
console.log("TEST TEST TEST");var app = require('../app');
var debug = require('debug')('ProjectTemplate:server');
var http = require('http');
var port = normalizePort(process.env.OPENSHIFT_NODEJS_PORT || "3000");
var server_ip_address = process.env.OPENSHIFT_NODEJS_IP || "127.0.0.1";
console.log("PORT: ", port);
和输出
TEST TEST TESTmodule.js:340
throw err;
^

来自入口点文件开头的日志记录语句。似乎在命中之前就失败了。console.log("PORT: ",
port);这很可能与app.js
建立MongoDb连接有关。

回答:
该错误原来是与端口无关的一般性错误。显然,如果出现致命的JavaScript错误,它会显示此消息。
