Much like Apple making their own hardware, they don't want the hassle of working things out for every bit of hardware out there. Likewise, Xojo don't want the hassle of working out every permutation of linux which is why the onus is on the developer/host.

Would you ask Ford why you car skids on ice when its using summer tyres?

@Julia T If my hosting service is expected to supply me with "a list of all installed libraries, OS versions, etc.", why can't the Xojo Cloud people just create and publish a similar dump of their installed libraries, OS versions, etc?

Because that would compromise their security. One of the vectors is knowing whats installed on a target so you can find out easily if there are exploitable vulnerabilities.

What are they running?

@Julia T centOS 6

Yes you would need to have CentOS 7.x (x64) for the GLIBC version you need

@Julia T centOS 6

https://unix.stackexchange.com/questions/176489/how-to-update-glibc-to-2-14-in-centos-6-5

Having not used linux full time for 20 years, your mileage may vary.

Whether the host will be willing or not to do this is another matter.

Did you try the 32bit thing I mentioned earlier, I think that doesn't need 2.14

That is the nature of shared hosting - it is shared. You can't say "please update the glibc version"

@Julia T centOS 6

This is exactly what I ran into with inMotion, the company that hosted my web site for many years. They have thousands and thousands of servers, all running centOS 6, and they're going to keep them all running the exact same OS because it's easier to maintain, they can swap identical hardware in and out without having to think about software requirements, and their technicians are all trained for 6. No way they'll upgrade a small number of servers to centOS 7.

So I moved my account to ServerWarp, which is a smaller company that is there to be helpful.

You can get a Windows Server VPS (2016 or 2012 R2) here for $29.99 per month and it includes virus protection. Not the cheapest but it works and the tech support is the best I have experienced. If you want to go LINUX you can save money but Windows makes configuring pretty easy since I am not very LINUX fluent.

I run the Silver version and it works well but if the load is light the starter version probably would be OK if the Xojo app is not too big.

In the long run I gave up on CGI due to performance issues and run stand alone Xojo Web Apps with NGINX in the front to handle multiple domains on a single IP. CGI also adds some to the server overhead with a Web server and the config complexity. NGINX also manages the Certs and HTTPS. There are some threads here on NGINX setup and config. If you want to consider NGINX on Windows I would be happy to share my config info.

@Oliver O Once we overcome the "Linux-is-complicated" mental block of the typical Windows user (as I had and was), then you quickly google on how to setup Webmin or Virtualmin on your linux vps. No witchcraft at all, and from that webinterface you manage everything necessary. No need to overload your server with a GUI.

Honest question: would either of those tools help Julia resolve her deployment issues?

Linux is solid, secure, robust...but unfortunately it is needlessly complex, and that's not a 'mindset.' I would call it an emergent property of both its developer culture and the dozens...hundreds...of competing distros. macOS or Windows would become more complicated overnight if there were dozens of new organizations shipping their own customized versions with their own library load outs. It's just the nature of the thing.

The client already has a linux server, I think Julia is trying to deploy to that to keep the clients costs to a minimum.

for now the cost of deployment is at the maximum (and has not been reached ...)

Well, either you spend more money for hosting, or more time with learning. Julia was able to master Xojo programming so she definitely is able to learn how to manage a linux vps.

Otherwise there is no such thing like running Xojo webapps on cheap shared webhosting. The time that is lost by trying to make such thing work would be better invested in learning how to install virtualmin/webmin and then using it to setup firewall rules and automatic security updates.

Of that I have no doubt. But $20/month vs $10/month? If I spend an hour trying to get something running on Linux I just paid for the difference for a year.

To be clear, I have recommended and used Linux before. But Linux headaches weigh on my mind any time I decide between a Linux and a Windows VPS.

is any way to some one connect by ssh and help
