I am getting the following error even though I have verified that the PassengerAgent exists at that location. The application I am trying to run is a nodeJS application on a cPanel apache server. I have root access to the server.
An error occurred while starting the web application. It exited before signalling successful startup back to Phusion Passenger. Please read this article for more information about this problem.
Raw process output:
SpawnPreparerShell: /usr/local/share/gems/gems/passenger-5.0.28/buildout/support-binaries/PassengerAgent: No such file or directory
I have finally figured out what my problem was. I had CageFS installed and activated. Even though the permissions and ownership to PassengerAgent were correct, somehow CageFS was still blocking access to it from the user. I still need to figure out how to prevent CageFS from blocking it, but at least I know what the problem is. I will probably change the installation to a new directory. I will post another reply when I have discovered how to let CageFS and Phusion Passenger work together.

I tried setting up a do-nothing Node app, and it failed.
I developed some Node.js code offline in containers. I now want to try deploying it on DreamHost. I am doing it incrementally, adding features one by one. Starting with “Hello World” and going from there.
I set up a new subdomain and enabled Passenger. I was able to serve up an index.html file. I followed https://help.dreamhost.com/hc/en-us/articles/360029083351-Installing-a-custom-version-of-NVM-and-Node-js and installed Node and nvm (using the versions recommended in that artcle). I then installed a few packages I plan to use (most notably Express, the rest won’t come into play until later).
With just a Hello World app, that failed. The error message is below. But, I checked all the relevant files and they all have global read and execute permissions. I’m wondering if it is something else. I tried multiple Hello World examples for app.js, copied directly from different tutorials, none of which worked (but they do work locally). My more complex code also does not work, but that is the next step.
What am I missing? I followed the directions exactly. What other landmines do I have to look forward to? I really don’t want to spend time wrestling with infrastructure, I want it to “just work”, ideally.

Raw process output:
*** ERROR ***: Cannot execute /home/<user name>/.nvm/versions/node/v12.16.3: Permission denied (13)
Unclear what solved the issue.
Ran through changing the permissions on the files, as would seem obvious. Changed '/home/<user name>/.nvm/versions/node/v12.16.3' to '/home/<user name>/.nvm/versions/node/v12.16.3/bin/node' in the .htaccess file. Neither of those seemed to solve it.
Repeated the process again later. Followed it by `touch <webapp directory>/tmp/restart.txt' and it started working. I had been editing files in the web app's directory, so it isn't clear what touching that file did.
I have a web app developed with a NodeJS + Express + GraphQL + MongoDB back-end and a ReactJS + Apollo front-end. I would like to deploy this application locally. Is that even possible?
I have come across dozens of "how to deploy to Heroku," "how to deploy to Digital Ocean", "how to deploy to Github", etc. But none that explains how to deploy locally.
Right now, I run: nodemon server for the back-end, and npm start for the front-end. I see the application running on http://localhost:3000/ (I use cors to connect the front end with the server running on port 3001).
I would like to just go to http://localhost:3000/ and see the app without having to execute the commands npm start and nodemon server. Is this possible? If so, how do I do that?
To my knowledge, our local server is not a WAMP server (our OS is Windows though). The IT department told me that it is a
[...] plain, regular old server. The address is localhost running on
port 3000. You can open up another port on 3001 if you need it. Just
drop your stuff on the C: drive and you should be good to go. I've
never heard of Node or React so I can't help if you have questions.
Any ideas? Many thanks in advance for your help!
UPDATE
There seems to be a bit of confusion surrounding what I am looking for. I am trying to deploy this locally.
Let's say, on your local computer (your laptop at home) you go to localhost:3000 on your favorite browser. Unless you are serving something to localhost in that moment nothing is going to show up, it will say "refused to connect" or something. What I want is to be able to open any machine on the network whenever I go to localhost:3000 and my react site appears and functions...does that make more sense?
I don't want this is development mode. I want a build of this project on localhost...I'm starting to think this isn't possible.
As i understood, you want to deploy it on a local server, not locally on your developing device.
I thought about doing that...but I'm not so sure IT will be okay with it always running... :(
How can you use a server if its not running? Just like WAMP (which runs apache), or whatever you got rolling there, it must be running. So, just make it a background process like slawomir suggested.
PS I dont think you understand node server properly though.
Read this to understand why node server needs reloading. After that you need to understand that no hot reload tool is perfect, and you gonna need to restart your server from time to time.
PPS I dont know what this means
[...] plain, regular old server. The address is localhost running on port 3000.
if there is a server running on 3000, youll need to change port for your server to smth else (most common is 9000)
To solve the problem you can create a startup script, which executes npm start and nodemon server. Then make sure to keep it hidden, so that your server will be always running. Keep in mind though, that any errors thrown will stop your server and unless you configure it, the server won't reload by itself.
I would try following:
build your app with the production environment variables set
get all files from dist folder and deploy them in your server
now access your app using localhost/
Maybe what you are looking for is something like ngrok which creates a socks tunnel to your localhost, effectivelly deploying from localhost, as I understand it, allowing you to access your localhost through a url like ldiuhv093.ngrok.io, or even a custom subdomain if you pay for a subscription fee.
If I have this wrong, someone please tell me!
To solve the problem first of need to create a batch file with .bat or .cmd extension and under that file add the following 2 command
nodemon server
npm start
Then follows the following steps to add it as a startup script for windows OS.
Create a shortcut to the batch file.
Once the shortcut has been created, right-click the file and select
Cut.
Press the Start button and type Run and press enter.
In the Run window, type shell:startup to open the Startup folder.
Once the Startup folder has been opened, click the Home tab at the
top of the folder and select Paste to paste the shortcut into the
folder.
Above steps are for example to create a batch file and add it as a startup script for Windows 8 and 10 users.

There's no option to reload the server while keeping it running. You could, technically, have your 'main' file monitor another file for changes. This would be the file where you actually keep your sever program. Then, on changes, you discard your current logic and start executing that. That said, doing it that way would be very fragile and a very round-about way to do it. It also wouldn't fix your front-end for which you'd need a similar solution.
Instead, you could hook into your favorite editor's save event, and run those two console commands, so that every time you save, the server is automatically brought up. (Make sure to also clean up existing servers)

I know this post has been two years. But, I think the solution to your second desired outcome is to use concurrency. https://www.npmjs.com/package/concurrently.
This will allow you to do one NPM START to start two all three processes.
and to your first question, I think the solution is to add Electron to your app so you can package it to an executable application. When you start the app, your express server will start running in the background.
Most people probably don't understand why there is a need for this. Running on local server (computer) allows access to local file system and can even run SQL queries inside the proxy which would require IT involvement if hosted on outside server.
From what I have understand, that you want to deploy your app on local server that means you want to deploy it on the network that you are connected to.
Check ip from the command prompt
To deploy it locally,
Run: HOST=ip npm run start
It will get deploy on your local server. And everyone connected to the server can access the url
If this worked for you, kindly upvote
You need to do npm start There may be other ways of starting it but, all will result in the same. You can read this article on Freecodecamp on deploying on DigitalOcean. You can manipulate it to your localhost. Shouldn't be too different.FCC Tut on Deploying
I am using ODIExportMaster tool in a package. The tool will create a zip file and save on server. The server is Linux machine and agent also reside on the same system as that of odi.
The code runs fine for dev and test environment. but its giving error as 'Can not create directory' on production server.
The user has same rights in all the environment.
Kindly guide me if anybody have any idea.
/Regards
if i am not wrong you are executing the package from client machinei, isn't it?
if so, please check with your production system Admin if you have access to the user where your client is installed.
or if you are running scenario on server it self instead of client machine, still if it is giving error try to understand why is it trying to create directory?
OR if it is directing a wrong error.
I am trying to revamp a website. The host uses cPanel as control panel.
I changed something in index.htm file but still the old version of website gets loaded.
Just to check, I created another html file index1.htm. When I pinged the <domain-name>/index1.htm, I got the right page loaded.
What possibly is going wrong here? Is there caching happening, if yes, how can i remove it.
Yes, May be Memcached modules in installed on your server and due to that your are getting this issues, If you want to clear that cache, You will have to access your server through SSH and try with following command.
telnet localhost 11211
flush_all
quit
I've got hgweb up and running on II7 7 (on windows server 2008). The web interface works, and I can view, pull, and clone the repositories there. But I cannot push, doing so gives me a 502 error right after "searching for changes". Using --debug shows the last few lines as:
sending unbundle command
sending 622 bytes
HTTP Error: 502 (Bad Gateway)
I am using TortoiseHG to push, but the result is the same when using the mercurial command line.
I had followed the tutorial here: http://www.sjmdev.com/blog/post/2011/03/30/setting-mercurial-18-server-iis7-windows-server-2008-r2.aspx to setup hgweb.
Looks like an old question but someone is bound to come across it again. I was close to drawing a black circle on a wall and ... anyhow the issue for us was the way central repository was created. We cloned it from BitBucket while being Remote connected to the machine as local administrator.
The issue was in [Repository].hg folder. You need to set correct permissions on it. Try it with adding Everyone -> Full permissions for test purpose. Please make sure you change this to a dedicated network login or appropriate local account afterwards.
I was seeing the exact same behaviour - even push worked fine with exception of getting a Bad Gateway after all the time. After correct permissions were set the issue was gone.
Thinking about it now, probably the best solution is to add each network login that uses the repo to machine users and then set up access permissions to .hg folder to local users.
Hope it helps someone.
Try using the ISAPI module method instead of the CGI that executes phython.exe as documented here. There's also another related, and possibly duplicate question here as well.
Take a look at the 'Push_ssl' setting in your hgweb.config file.
I was getting the same error (had mine set to '*'), and was able to resolve it by removing the line entirely. Granted, this makes Mercurial somewhat less secure, but it lets me get by the configuration issue (for now) while I investigate properly configuring SSL on the server.
You may also have to review the 'Allow_push' setting in order to get past further errors (or take another look at your authorization).
NOTE: At least in my case, having 'push_ssl = false' wasn't enough as that resulted in further errors (authorization failed).
(Again this is simply a temporary solution until the server can be properly secured.)
It could happen by different reasons, to get more details about the error run
hg push --config ui.usehttp2=true --config ui.http2debuglevel=info
For example, problem may occur because of proxy server or just in case when the Mercurial Web Server "forgets" about repositories it needs to serve: in case if you are using TortoiseHg workbench go to Workbench UI, Repository -> Start Web Server, make sure that your repository is in the list of the served repos.
Try use https instead http in .hg/hgrc, I have resolve this problem for code.google.com.
I had this issue, and the problem ended up being the server running out of disk space.
