Synchronize PHP between two servers - linux

what you think is the best way to synchronize PHP code between two servers. One server i production and second is testing server. They have linux and are separated (have another IP). How would you solve synchronize PHP code, when you want send a PHP code from testing server to production?
Thanks for your answer

Deploying Next.js to Apache server

I've been developing a Next.js website locally and now want to set it up on my Apache server (with cPanel). However, I'm very new to Next.js and Node apps and not too sure how to go about it.
Has anyone done this successfully? Can you list the required steps and what files should be on the server?
Also, can this be done on a subdomain?
Thank you!
To start with some clear terms just so we're on the same page, there are two or three very different things people mean when they say "server":
A Server Machine is a computer that is connected to the internet that you intend to use to serve something to people on the internet.
A Server Program is some software you run on your Server Machine. The job of the Server Program is to actually calculate the responses to various requests.
A Server as a Service is a webapp provided by a company that stores your code and then puts it onto Server Machines with the right Server Program as needed.
While we're here, let's also define:
A Programming Language is the language your website is written in. Some sites have no language (and are just raw HTML/CSS files that are meant to be returned directly to the user). Many sites, though, have some code that should be run on the server and then the result of that code should be returned to the user.
In your case, you have a Machine whose condition we don't know other than that it is running the Program Apache (or probably "Apache HTTP Server"). Apache HTTP server is very old and proven and pretty good at serving raw files back to users. It can also run some Programming Languages like PHP and return the result.
However, Next.JS is built on top of the Programming Language Javascript, which Apache does not have the ability to run. Next.JS instead wants its Server Program to be Node.
So the problem here is basically that you have a hammer, but only screws. You can't use the tool you have, Apache, to solve the problem you need solved, running Node code and returning the result. To get around this you have two options:
First, you can find a way to access the Server Machine that is currently running Apache and tell it, instead, to run Node pointed at your Next.JS code whenever it starts up. This might not be possible, depending on who owns this machine and how they've set it up.
Second, and probably easier, is to abandon this Machine and instead use a Server as a Service. Heroku, AWS, and Netlify all support Next.JS and have a free tier. The easiest solution, though, is probably to just deploy it on Vercel, which is a Server as a Service run by the same team that makes Next.JS and which has a very generous free tier for you to get started with.
The good news, though, is that yes next.js does totally support being hosted from a subdomain.
Next.JS allows you to build fully functional Node Applications, as well as simple statically-generated sites like Jeckyl or Docpad. If your use case is a simple statically generated site look here: https://nextjs.org/docs/advanced-features/static-html-export
In particular the next build && next export command will create all the HTML and assets necessary to host a site directly via an HTTP server like Apache or Ngnix. Contents will be outputed to an out directory that could serve as the server root.
Pay very close attention to what features are not supported via this approach.

Use nodejs to host multiple html websites instead of apache

I currently use Apache2 to host multiple websites for some friends, and as i've been experimenting with NodeJS I was wondering if it was possible to host these sites with NodeJs?
I wanted to have a folder structure like the following:
App
--> server
--> websites
`--> site1 (example1.com)
`--> site2 (example2.com)
With more people asking me to host there sites I need to be able to easily create a new site quickly with out restarting the server effecting other hosted sites.
Currently I use a bash script to create the folder structure for apache and add a new virtualhost in the apache conf file and finally reload apache.
So my main question is, should I even be looking at nodejs for this or stick with apache?
Any opinions, examples or tutorials would be great.
You're probably better off staying with apache (or possibly switching to nginx). In fact, best practice for production node.js servers is typically to run them behind apache/nginx through a reverse proxy. Few reasons for that:
You have to run node.js as root to give it access to port 80/443 (generally bad idea)
You're going to be very hard-pressed (and probably a lot of trial and error) to get the security, performance and stability of apache/nginx.

Setup Node server with multiple websites and have each site on its own thread

I have a laptop that I am running node on, a Ubuntu Server with a quad core processor.
There is a plan for 2-3 sites on this server and I am not a really good admin and needed help getting this one site going so I dont want to start from scratch and run a hypervisor. Is there a way to have node host 3 sites and have each of the run on their own thread of the processor? I understand Node is single threaded and while I really dont need to do this for performance (because its just for development) I do like this as an exercise in doing things in node and it would be cool! There is an entire second laptop for the database so Im not worried about resources.
So 3 sites on one instance of Ubuntu Server all on different threads.....
It's not entirely clear what you're trying to accomplish. Here are a couple scenarios:
Create three separate node.js servers, each listening to their own port and they will each be running their own node.js process independent of the other. Then have each client connect to the appropriate port.
Create three separate node.js servers, each listening to their own port and they will each be running their own node.js process independent of the other. Use NGINX as a proxy in front of the three web servers and you can let NGINX direct requests all on port 80 from each of the three domains to the appropriate node.js web server. Using NGINX this way, all three web servers can appear to be be running on the default port 80 (or 443) and NGINX will separate them out and direct them to the appropriate web server process.
Create your own master node.js process that receives requests for all three domains, looks that the host header to see what domain the request was actually directed at and then forward that request to the appropriate child process. This would be similar to the way clustering works in node.js, but each child process would be each of your different web servers. Personally, I'd use the pre-built functionality in NGINX to do this for you (as described in option 2 above), but you could code it yourself if you didn't want to run NGINX.
Instead of NGINX, use some sort of load balancer that your ISP may already have to direct the incoming connections to the right server process.
If you run 3 different applications ie. sites then they will be running as different processes on your server which assuming all run on different ports, there should be no problem running them simultaneously. When you refer to node being single threaded that applies to a single process so each process has its own event loop running.

Serve nodejs app from nginx like with php?

I use Nginx to serve my php applications for dev purposes.
On Ubuntu it works out of the box.
I want to do the same for Node.js apps.
Is this possible without doing nodejs app.js before?
How to achieve this in a single Nginx conf file?
PHP and node.js are oil and water. PHP requires a web server to run the .php files, however node.js typically creates its own web server. Since you are creating your own web server, in many cases you wouldn't find it necessary to serve your application from Nginx, however, if you truly insisted on "serving" it from Nginx, you would need to proxy it.
This is not possible without doing nodejs app.js before, due to the way node.js works.
This question best answers your question regarding proxy'ing via Nginx.
As a closing remark, its good to remember that node.js does in fact (in most cases) implement its own web server, and PHP does not.

Node equivalent to index.html

I'm coming from a LAMP background and want to test out node for production.
What seems a little confusing to me is that in Apache url's map to folders, and the server will automatically look for an index.html or index.php if you aren't re-writing urls.
What would the equivalent be in node?
I'm thinking it'd be something like checking the request url and matching it, then loading a specific node module which runs the app.
This might seems simple for a single app, but we run tons of client apps on our server so i'm used to having different frameworks in different folders and index.php just runs it.
to be more specific. i'm currently running a few codeigniter and wordpress installations on our server. so i'd want to run a few node apps/frameworkds in different 'subfolders'
With Node you don't really use Apache. It's similar to Ruby in that is runs its own web server.
However, you can probably get Apache to run Node files using mod_node. As far as I know this is non-standard though and you definitely lose the "non-blocking" advantages of Node. But for experimenting (and not load testing) it's fine.
Check out Express if you're looking for an MVC architecture written in Node.
If you're just looking to run the most basic sample web server, just run the example hosted on the main page: http://nodejs.org/
Lastly, I had that same issue you are experiencing where I have one box hosting a lost of stuff and Apache taking up port 80. The answer here is to use a reverse proxy like Nginx to run on port 80 and redirect traffic to Apache / Node / Ruby / etc. Best of both worlds and since Nginx is written non-blocking you still gain the benefits of node.
I actually wrote an in-depth blog article about this a few months ago:
