节点js-应用程序没有端口号

Question

我刚刚开始使用节点js,我已经在服务器上开发了一个应用程序和主机,但只有当我分配port number我希望它只通过域名运行时它才会运行.我搜索了很多,但它没有使用我的全部我试图重写服务器中的httpd.conf文件

/etc/httpd/conf/httpd.conf中

<VirtualHost 119.19.52.203:80>
ServerName aip.xyz
ProxyRequests off
<Proxy 119.19.52.203:80>
        Order allow,deny
        Allow from all
</Proxy>

ProxyPass / http://example.xyz:5000/
ProxyPassReverse / http://example.xyz:5000/
ProxyPreserveHost on

并且也点击此链接

1. nodejs-没有端口号的域
2. apache服务器配置

这是我的httpd.conf文件代码(在服务器上自动生成)

<VirtualHost 118.18.52.203:80>
ServerName example.xyz
ServerAlias www.example.xyz
DocumentRoot /home/example/public_html
ServerAdmin webmaster@example.xyz
UseCanonicalName Off
CustomLog /usr/local/apache/domlogs/example.xyz combined
CustomLog /usr/local/apache/domlogs/aip.xyz-bytes_log "%{%s}t %I .\n%{%s}t %O ."
## User example # Needed for Cpanel::ApacheConf
UserDir enabled aip
<IfModule mod_suphp.c>
    suPHP_UserGroup aip aip
</IfModule>
<IfModule !mod_disable_suexec.c>
    <IfModule !mod_ruid2.c>
        SuexecUserGroup aip aip
    </IfModule>
</IfModule>
<IfModule mod_ruid2.c>
    RMode config
    RUidGid aip aip
</IfModule>
<IfModule itk.c>
    # For more information on MPM ITK, please read:
    #   http://mpm-itk.sesse.net/
    AssignUserID example example
</IfModule>
ScriptAlias /cgi-bin/ /home/aip/public_html/cgi-bin/
# To customize this VirtualHost use an include file at the following location
# Include "/usr/local/apache/conf/userdata/std/2_2/aip/aip.xyz/*.conf"

之后,我已经插入此代码,只需简化配置

Listen 80
<VirtualHost example.xyz>
ServerName example.xyz
ProxyPass / http://example.xyz:5000/
ProxyPassReverse / http://example.xyz:5000/
ProxyPreserveHost On 
</VirtualHost>

这是我的路线代码// app.js

var express = require('express');
port = process.env.PORT || 5000
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var soft1 = require('./routes/soft1');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.engine('hjs', require('hogan-express'));
app.set('view engine', 'hjs');
app.set('layout', 'layout/default');
app.set('partials', {
mainHead: "include/main/head",
mainContent:  "include/main/maincontent",
mainSlider:  "include/main/slider",
mainLogo:  "include/main/logo",
mainTopmenu:  "include/main/topmenu",
mainSocial: "include/main/socialicons",
mainPortfolio: "include/main/portfolio",
mainSubmenu: "include/main/sbumenu"
});
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
app.use('/soft1', soft1);
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
        message: err.message,
        error: err
});
});
}
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
    message:err.message,
    error: {}
});
});
app.listen(port, function() {
console.log('Listening on port ' + port)
})
module.exports = app;

它还没有工作,没有正确的路由.当我访问example.xyz时,它的show目录结构(应用程序的所有文件和文件夹).

这里有2个进程:

• NodeJS流程,为您的应用程序提供服务
• httpd(Apache)进程,通常用作在一个域上提供多个应用程序的入口点.

他们都需要监听端口才能访问.

通常做的是让Apache或Nginx进程在默认端口80上进行侦听,默认端口80是唯一对外部连接开放的http端口.然后使用此Apache进程代理您在其他端口上运行的应用程序(例如5000,不应为外部连接打开).

在您的httpd conf中,您可以在您的域上,在默认端口(80)上有一个入口点,并使用反向代理在端口5000上与您联系节点应用程序:

Listen 80
<VirtualHost aip.xyz>
  ServerName aip.xyz
  ProxyPass / http://aip.xyz:5000/
  ProxyPassReverse / http://aip.xyz:5000/
  ProxyPreserveHost On
</VirtualHost>

当你想在1个端口(通常80)后面托管多个应用程序时,这很有用,即:

Listen 80
<VirtualHost aip.xyz>
  ServerName aip.xyz
  ProxyPass /app1/ http://aip.xyz:5000/
  ProxyPassReverse /app1/ http://aip.xyz:5000/
  ProxyPass /appX/ http://aip.xyz:500X/
  ProxyPassReverse /appX/ http://aip.xyz:500X/
  ProxyPreserveHost On
</VirtualHost>
