Hi,
There are two separate issues here:
Posit say that their OS shiny server is only
installable on:
Red Hat Enterprise Linux 8 and higher
Ubuntu 22.04 and higher (LTS releases only)
SUSE Linux Enterprise Server 15 SP7
(from https://docs.posit.co/shiny-server/)
You are linking here to Shiny Server Pro Admin Guide which is their
paid offering and for that they support the above distributions.
Yes. Apologies. Oddly enough I think the link that took me to that was
from their open source shiny server pages. Thanks.
They did do the upgrade of the server to bookworm and the shiny server
is now on R 4.2.2. The apps are all runnning OK (and they are mostly
very simple) but this is clearly not good to be using a version of R
that is four years old.
This has nothing to do with Shiny Server, as the default R in bookworm
is 4.2.2 (https://packages.debian.org/bookworm/r-base). So you need to
see how to update R on bookworm if that is the distribution of choice.
Sorry. I did try but clearly I wasn't clear! I understand that, the
issue I have is that my ISP are under the impression that for the shiny
server to continue to work R has to be kept at 4.2.2. I think that is
not correct and that I could do the usual with /etc/apt/sources.list to
bring R to the current version as per the advice about trixie in
https://cran.r-project.org/bin/linux/debian/
I suppose there is a theoretical risk that the 4.6.1 version might have
a change in the shiny package (or, even less likely i think) any other
package that I use in my apps that the shiny-server installation can't
handle. I don't believe that is at all likely but perhaps someone here
is running open source shiny server (on any OS really) with R 4.6.1 and
can confirm that there are no such nasty issues?
The open source shiny server (https://github.com/rstudio/shiny-server)
has this in the README:
"""At this time, Shiny Server can be run on Linux servers with
explicit support for Ubuntu 14.04 or greater (64 bit) and CentOS/RHEL
6 (64 bit) or greater. If you are using one of these distributions,
please download the pre-packaged installers from RStudio:"""
Thanks. I really should have managed to find that. Apologies.
Interesting ... I know my ISP prefer to run servers on Debian but I know
they provide images of other Linux OSs if one is renting a machine or VM
from them so perhaps they might be happy to run Ubuntu for the shiny
server. I know that one can also compile the shiny server from source
and that could presumably be done in bookworm or trixie. However, some
years back when i tried to do that for a pi machine I lost a lot of time
and eventually had to give up as incompatibilities in the various
components that shiny-server uses as then implemented on the pi were
beyond me (and beyond some knowledgeable internet help) to overcome.
Again, perhaps there is someone on the list who has gone that route and
compiled the shiny server from source on bookworm or trixie and can
confirm it worked (relatively easily!)
You may also want to check out shinyproxy (https://www.shinyproxy.io/).
Thanks again. That looks impressive and is clearly very powerful.
However, it takes me into things like docker that I have so far not
learned and quite a lot of what is written there about how it works was
language I just don't know!
Many thanks,
Chris
