I have installed a node js application (myapp.js) on a server with a particular IP.
I have npm installed and started the application
I have done this before but it was with apache and much more complex.
However this is the only application on this server. It is running fine.
Shouldn't this just be available at the ip it is installed on?
My own guess is it is something to do with the node setup within the application, as its referring to a local host 8050? Maybe this needs to be an IP?
Edit
I have just installed the application on the server. I havent set up any apache so maybe that is the issue. I think perhaps because i defined a port within the application it then needs a port specified on the server?
Your node application could be accessed locally from:
http://localhost:8050/
And from outside at:
http://youripaddress:8050/
Assuming that port 8050 is open, naturally.
You can also setup a reverse proxy with apache or nginx (or anything else) to proxy your application.
I am creating one application that needs to be made on staging server from one point. Because creating it on local is impossible as it has some endpoints that other servers in network has to access.
I have created an application in Vue.js and Laravel. In local, I used to run npm run hot so that I don't have to re-compile when I change some code. But as I have to continue developing this application on a live server, I want to run npm run hot on a custom domain like staging.something.com instead of localhost:8080.
I don't have any issue if somehow localhost:8080 co-operates but when I run npm run hot on a live server, Here is the error I get when I try to access the web application.
GET http://localhost:8080//js/app.js net::ERR_CONNECTION_REFUSED
I think it should show IP address of my server instead of localhost. I don't know what's wrong with this but it's not working.
Laravel mix uses the webpack-dev-server package for the run hot command.
webpack-dev-server has a switch --useLocalIp which will make it use the servers local IP address.
It also has a --host switch which can be used to set the IP address manually --host 0.0.0.0
It is a simple node.js code.
var http = require('http');
http.createServer(function(req, res) {
res.writeHead(200, { 'Content-Type' : 'text/plain'});
res.end('Hello World!');
}).listen(8080);
I uploaded it on cpanel hosting server and installed node.js and run it.
If a server is normal server I can check script result by accessing 'http://{serverip}:8080'. But on cpanel is hosting domain and sub domain and every domain is matched by every sites. Even http://{serverip} is not valid url.
How can I access my node.js result?
Kindly teach me.
Thanks.

Install/Setup NodeJS with CPanel
1. Log in to your account using SSH (if it is not enabled for your account, contact the support team).
2. Download Node.js
wget https://nodejs.org/dist/latest/node-v10.0.0-linux-arm64.tar.xz
3. Extract the Node.js files
tar xvf node-v10.0.0-linux-arm64.tar.xz
4.Now rename the folder to "nodejs". To do this, type the following command
mv node-v10.0.0-linux nodejs
5. Now to install the node and npm binaries, type the following commands:
mkdir ~/bin <br> cp nodejs/bin/node ~/bin
cd ~/bin
ln -s
../nodejs/lib/node_modules/npm/bin/npm-cli.js npm
6. Node.js and npm are installed on your account. To verify this, type the following commands
node --version
npm --version
The ~/bin directory is in your path by default, which means you can run node and npm from any directory in your account.
7. Start Node.js Application
nohup node my_app.js &
8. Stop the Application
pkill node
9. Integrating a Node.js application with the web server(optional)
Depending on the type of Node.js application you are running, you may want to be able to access it using a web browser. To do this, you need to select an unused port for the Node.js application to listen on, and then define server rewrite rules that redirect visitors to the application.
In a text editor, add the following lines to the .htaccess file in the/home/username/public_html directory, where username represents your account username:
RewriteEngine On
RewriteRule ^$ http://127.0.0.1:XXXXX/ [P,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ http://127.0.0.1:XXXXX/$1 [P,L]
In both RewriteRule lines, replace XXXXX with the port on which your Node.js application listens.
To run a Node.js application on a managed server, you must select an unused port, and the port number must be between 49152 and 65535(inclusive).
Save the changes to the .htaccess file, and then exit the text editor. Visitors to your website are redirected to the Node.js application listening on the specified port.
If your application fails to start, the port you chose may already be in use. Check the application log for error codes like EADDRINUSE that indicate the port is in use. If it is, select a different port number, update your application’s configuration and the .htaccess file, and then try again.
cPanel typically runs Apache or another web server that is shared among all the cPanel/unix accounts. The web server listens on port 80. Depending on the domain name in the requested URL, the web server uses "Virtual Hosting" to figure out which cPanel/unix account should process the request, i.e. in which home directory to find the files to serve and scripts to run. If the URL only contains an IP address, cPanel has to default to one of cPanel accounts.
Ordinarily, without root access, a job run by a cPanel account cannot listen on port 80. Indeed, the available ports might be quite restrictive. If 8080 doesn't work, you might try 60000. To access a running node.js server, you'll need to have the port number it's listening on. Since that is the only job listening on that port on that server, you should be able to point your browser to the domain name of any of the cPanel accounts or even the IP address of the server, adding the port number to the URL. But, it's typical to use the domain name for the cPanel account running the node.js job, e.g. http://cPanelDomainName.com:60000/ .
Of course port 80 is the default for web services, and relatively few users are familiar with optional port numbers in URLs. To make things easier for users, you can use Apache to "reverse proxy" requests on port 80 to the port that the node.js process is listening on. This can be done using Apache's RewriteRule directive in a configuration or .htaccess file. This reverse proxying of requests arguably has other benefits as well, e.g. Apache may be a more secure, reliable and manageable front-end for facing the public Internet.
Unfortunately, this setup for node.js is not endorsed by all web hosting companies. One hosting company that supports it, even on its inexpensive shared hosting offerings, is A2Hosting.com. They also have a clearly written description of the setup process in their Knowledge Base.
Finally, it's worth noting that the developers of cPanel are working on built-in node.js support. "If all of the stars align we might see this land as soon as version 68," i.e. perhaps early 2018.

How to host a Node.Js application in shared hosting
Why node.js can't run on shared hosting?
Yes it's possible, but it has few dependencies which may or may not be supported by either your cpanel hosting provider or the plan you opt in for.
Below steps that I'm mentioning is just for a demo purpose. If you are a student or just want to play with it you can try it out. I'm not a security expert so from security point of view how good it is I really don't know.
So with that being said let's see how I configured it. I have hostinger cpanel hosting subscription and following are the steps:
Enable SSH ACCESS
Connect to shared machine via ssh
Check your linux distro and download & setup node js
In my case following are the commands for that:
Downloading node & extracting it using curl
curl https://nodejs.org/dist/v12.18.3/node-v12.18.3-linux-x64.tar.gz |tar xz
This will download & extract node & create a directory. You can confirm that using ls command as shown in the image below.
At this point you can check the versions as shown below
as you can see for the node command it's okay but for the npm command we have modify it as follows
./node-v12.18.3-linux-x64/bin/node ./node-v12.18.3-linux-x64/lib/node_modules/npm/bin/npm-cli.js --version
Further we can create alias to make life little easier
check the below images for that:
I tried using bashrc/bash_profile but somehow it didn't work .
And that's all node server running on a shared cpanel machine.
Now I wanted to have an express js based rest api support in this case. The problem with that is it will be locally hosted on the port I'll give. Check the below example:
var express=require('express')
var app=express()
app.get('/', function (req, res) {
res.send('hosting node js base express api using php & shared hosting a great way to start yjtools')
})
console.log("listening yjtools node server on port 49876...")
app.listen(49876)
The problem here is even though it will execute I'll not be able to access it over the network. This is because we only get fixed predefined ports (like 80,21,3306 etc.) which are allowed/open on the shared cpanel machine. Due to this the express app I hosted will only available locally on 49876 port.
Let's see what do we have:
An express js based app hosted locally on cpanel machine.
Php based hosted Apache server available over http/https.
So we can make use of php with redirect rule set and curl to bridge the gap.
Following are the changes I did to make it work:
In .htaccess file add a redirect rule, say domain/api is what I want my rest api path to be.
RewriteRule api/(.*)$ api/api.php?request=$1 [QSA,NC,L]
In the api/api.php file (this is the path I choose you can choose any path)
<?php
echo "Hello ".$_REQUEST['username'];
echo '<hr>';
$curl = curl_init('http://127.0.0.1:49976/');
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//Get the full response
$resp = curl_exec($curl);
if($resp === false) {
//If couldn't connect, try increasing usleep
echo 'Error: ' . curl_error($curl);
} else {
//Split response headers and body
list($head, $body) = explode("\r\n\r\n", $resp, 2);
$headarr = explode("\n", $head);
//Print headers
foreach($headarr as $headval) {
header($headval);
}
//Print body
echo $body;
}
//Close connection
curl_close($curl);
?>
And on the ssh prompt just run the app.js file
node api/app.js
Below are the images for this working in action:
Here is the similar thing which I referred for my program, so we can also make this node call via php itself.
Now I have express based rest api support , angular app hosted and mysql for database everything on cpanel.
You can use any domain pointed to that cPanel server and instead of accessing http://server-ip:8080 try accessing http://domain.tld:8080. By default cPanel does not bind on port 8080. Be sure to check if there is any firewall on the server. If it is, then allow incoming connections on tcp port 8080. Depending on your WHM server configuration, it should also work with http://server-ip:8080
cPanel Version 80 has nodejs 10.x support: https://documentation.cpanel.net/display/80Docs/80+Release+Notes#id-80ReleaseNotes-InstallanduseNode.jsapplications
Install and use Node.js applications
You can now install and use Node.js applications on your server. To
use Node.js, install the ea-nodejs10 module in the Additional Packages
section of WHM's EasyApache 4 interface (WHM >> Home >> Software >>
EasyApache 4).
You can register Node.js applications in cPanel's Application Manager
interface (cPanel >> Home >> Software >> Application Manager). For
more information, read our Guide to Node.js Installations
documentation.
For Application Manager to be enabled: https://documentation.cpanel.net/display/80Docs/Application+Manager
Your hosting provider must enable the Application Manager feature in
WHM's Feature Manager interface (WHM >> Home >> Packages >> Feature
Manager).
Your hosting provider must install the following Apache modules:
The ea-ruby24-mod_passengermodule. Note: This module disables Apache's
mod_userdir module.
The ea-apache24-mod_env module. Note: This module allows you to add
environment variables when you register your application. For more
information about environment variables, read the Environment
Variables section below.
The ea-nodejs10 module if you want to register a Node.js™ application.
You can see how application manager looks like in this Youtube video:

I have installed strongloop loopback application on a live server on domain e.g: www.abc.com . I have created stronglooop loopback project in a subfolder called "lb" After successfull creation I executed the command "slc run" the terminal logs that your loopback app is running on http://localhost:3000 but when I opened www.abc.com/lb or www.abc.com:3000/lb... it was not running there ... What mistake I did? thanks in advance.
Your loopback running on same domain but on another port so you can access it by http://www.example.com:3000
It's doesn't matter which folder your application is stored. When you run it, by default it runs on default domain on port 3000.
You should be able to deploy your app to that server using the command:
$ slc deploy http://user:pass#prod1.example.com:3000

Is there any advantage in testing the ionic app on a web browser using the the ionic serve command vs just running a local apache server and browsing the www folder (e.g. http://localhost/www/#/app/home). I checked the serve.js file in the npm module and apparently all it does is listening for a tcp connection on a default port using nodejs modules.
There are a few advantages, but you are certainly able to use a local apache server as well.
ionic serve benefits
It runs with the ability to have live reload, meaning if you save a file in your editor the app will auto-refresh in your browser. You can disable by with the -r flag on the command.
It can open a browser when you start up, which can be nice or annoying. You can disable with the -b flag on the command.
It sets up a local server for you, regardless if your files are in the apache www directory. It lets you store the files anywhere in your system.
Apache benefits
You can setup .htaccess rules to rewrite urls to properly support html5mode in Angular. I don't do this on mobile apps since the urls are not available in apps.
Runs on port 80. You don't have to worry about ports or remembering what port to use.
Its up to you really, but I use ionic serve. You can also use cordova serve which does the same as ionic serve without live reload and browser open, and runs on localhost:8000.
