Raspberry Pi web server "Clones / Redundancy"

[TechMeThatsSexy]

Hey guys,

 

I had a though the other day and wondered if it’s possible to have more than one Raspberry Pi as a web server, and one or more "clones" with the exact same website as backup sites?

 

You could have one Pi at home and another at work or at a friends house for example. 
 

So that in case of a fire or theft example and one of the Raspberry Pi’s are down, then the other Pi would automatically take over and keep the site up.

 

Thanks for any ideas or tips:)

I know there are Pi servers. I was actually just thinking about it! I am sure there is a program for that, but IDK what it is.

Have you look up webserver redundancy? Something like dns failover is probably best here.

 

If your doing hosting that a pi would work for, a vps is probalby a better solution.

I think it would be a good option for DIYers here. I would like to do such thing for a website of mine and long term i know that would save me money (and it is fun!). I also have dreams of making a web hosting service and this is just what I am looking for (until I can afford a small server).

That would be interesting to play with. I’ll post something here if I find something

Yeah. I would run Ubuntu unless there is something for Pi's because of ghost.org where you can easily host something on it but IDK about a failover tho. Pi clusters are very common.

This is for a generic mpi cluster, it work work for making a redundant website accross a wan.

 

The other problem with this here is that you need your program to be written to take advantage of the cluster, you can't just run any program on a cluster.

No, not yet. That might be thing!

Yeah I also though it would be a cheap way to have web server redundancy.

Same here. I would like to go crazy with a server rack in the future, but this would be a fun way to start:)

Would this work for a cluster that’s on different locations or on the same local network?

Need to code much or just customize program in terminal etc?

For Ghost self web hosting on a raspberry pi (without clusters) go here for a totorial: https://ghost.org/docs/install/ubuntu/ and I am hoping to find (or order) a micro-SD cad so I can do this ASAP on raspberry Pi

Ghost self web hosting

Thanks for the tip and tutorial. Please let me know if you test this out and set it up. Would like to follow your post  I’ll be ordering a Pi or two in the near future!

You don't really want a cluster like thiat. Just get 2 systems and sync the web root across them, then have dns failover for a simple failover webiste, but its gonna get a bit more complex if you need a database for the webiste. What site are you tyring to host.

You probably don't want to ghost here, but depends on the site. Id just try installing apache and set that up firs.t

You can use a load balancer for this..

Okey thanks for sending me in the right direction.

Would like to setup a basic Wordpress "blog"/site, with member login and some videos public (without login) and some locked content videos.

 

I haven’t figured out how to host the videos yet. I guess it would be best to host them on a separate site like Bitchute or something for example?

Ok, thanks for the tip. What’s is that, any link to article / info?

Really get a vps, probably cheap, much easier to setup, and better uptime.

Both nginx and apache have load balancer in them. Just to do the research and see if it works for you. You'll kind of need a reverse proxy anyways.

Ok, then I have some keywords to search for.

I have a VPS and I would rather host it my self. I want to have all the fun troubleshooting it and stuff. I know, I know, but I am paying $8/mo so 5 people can visit it. I barely get any views so it will be cheaper to self host.

Yeah, would be much more to learn and fun when setting it up our selves, and och save money in the long run.

A VPS then wouldn’t be much useful if there are more visitors.

 

My goal is to building a Pi NAS and PiVPN as well with a Pi3 probably as well.

 

I guess I should setup the web server on the Pi4 with 4GB? Any Pi expansion you would want?

And what size of SD would you recommend 32-64-128GB + maybe add a small SSD as well if useful in this case?

Get 128GB along with external storage (maybe 1TB HDD?). It depends what you are using it for (The NAS I mean).

I want to do something like that too. I have a 32GB micro-SD card and I don't know where it is.

I think you would need a CPU fan if you are doing a lot of stuff like that at once.

NAS

I have a spare 128GB SSD and 1TB HDD I can use for the NAS. I’m not sure yet since I already have a 1TB WD NAS, but want to build one with Pi to learn. 
 

I guess I don’t need any hard drives for the Pi web servers since I don’t host the video on the Pi’s. Just LAMP & WP on the SD if I’ve understood this correctly so far.

I don't understand anything you said so you are much more ahead then me. Good. You have the hardware.
