can you show us the contents of the pharo command because may be it is wrapping the Pharo command. did you try without snap (no idea what is it). Did you the script of sven because they work without snap.

Hi everyone,

New here, encouraged (from Discord) to try my questions here.

I’m struggling to get AWS to run in an Ubuntu AWS instance. I tried following the directions here: https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfu... but I was getting some error about threads and configurations that I simply didn’t understand. Then I tried using Pharo-snap: https://github.com/akgrant43/pharo-snap

Pharo-snap made some of the config problems go away, but when I try starting Pharo on AWS, I get:

*ubuntu@ip-172-31-16-17*:*~*$ ./pharo Pharo-sea-roa-sound.image

Usage: [<subcommand>] [--help] [--copyright] [--version] [--list] [ --no-quit ] --help print this help message --copyright print the copyrights --version print the version for the image and the vm --list list a description of all active command line handlers --no-quit keep the image running without activating any other command line handler --deploymentPassword if a password needs to be used by the user to launch the command --readWriteAccessMode, --readOnlyAccessMode, --writeOnlyAccessMode, --disabledAccessMode specify disk access mode, read-write mode as default <subcommand> a valid subcommand in --list

Preference File Modification: --preferences-file load the preferences from the given <FILE> --no-default-preferences do not load any preferences from the default locations

Documentation: A PharoCommandLineHandler handles default command line arguments and options. The PharoCommandLineHandler is activated before all other handlers. It first checks if another handler is available. If so it will activate the found handler.

Clearly, I’m doing something wrong, but don’t know what the next step is, since there isn’t an explicit error message. Can someone point a newbie towards the appropriate next steps?

Thanks! - Mark

THANK YOU, SVEN! That totally worked! It *didn’t* work when I tried to access the instance from a browser. (The curl to localhost did work.) I figured out that I also had to edit the AWS Security Groups to allow port 9090. But once I did that, I reached Pharo running on AWS from an external web browser! I also discovered that the image that I thought I’d pre-loaded with Seaside and my code wouldn’t start with this process at all. The job immediately quit. I need to learn better how to load an image appropriately. I’ll go back to the Enterprise book and learn about these scripts of yours. Thank you! - Mark

Mark,

Make sure to use 64-bit (that is 64-bit Pharo on 64-bit Linux), it will make your life much easier.

Here is a short example:

stfx@audio359:~$ mkdir pharo8

stfx@audio359:~$ cd !$ cd pharo8

stfx@audio359:~/pharo8$ curl get.pharo.org/64/80+vm | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3054 100 3054 0 0 67866 0 --:--:-- --:--:-- --:--:-- 69409 Downloading the latest 80 Image: http://files.pharo.org/get-files/80/pharo64.zip Pharo.image Downloading the latest pharoVM: http://files.pharo.org/get-files/80/pharo64-linux-stable.zip pharo-vm/pharo Creating starter scripts pharo and pharo-ui

stfx@audio359:~/pharo8$ nohup ./pharo Pharo.image eval --no-quit 'ZnServer startOn: 9090' & [1] 84125 nohup: ignoring input and appending output to 'nohup.out'

stfx@audio359:~/pharo8$ curl http://localhost:9090/random CF4173824EF6E0D9F336E5464A5FACB8ABEFFD1A6EE7A5F9F6631186F619606

stfx@audio359:~/pharo8$ jobs [1]+ Running nohup ./pharo Pharo.image eval --no-quit 'ZnServer startOn: 9090' &

stfx@audio359:~/pharo8$ kill %1 [1]+ Terminated nohup ./pharo Pharo.image eval --no-quit 'ZnServer startOn: 9090'

BTW, nohup is one way to keep something running after you log out (systemctl services being the pro/real way)

Is this not how it works out for you ?

Hi Mark, There is of course a significant learning curve here. You will need to understand what Metacello is, Monticello & Iceberg (GitHub) repositories, ConfigurationOfXXX & BaselineOfXXX. The books are good starting points. This is another recent thread: http://forum.world.st/running-Pharo8-in-Digitalocean-tt5115160.html HTH, Sven

Thanks, Sven. Yes, there’s a big learning curve to be able to use your scripts, but they do seem powerful. I’m trying to work my way through your minimal-pharo-server-tools. I’m using these scripts right now: $ git clone https://github.com/svenvc/minimal-pharo-server-tools.git $ ~/minimal-pharo-server-tools/install.sh $ cd build && ~/pharo/build.sh $ ~/minimal-pharo-server-tools/run/pharo-http-server/deploy.sh $ sudo systemctl start pharo-http-server Cloning and installing went fine. I’m working on this line "cd build && ~/pharo/build.sh.” There is no build directory in cloned git repository. There is a build.sh, but it has hard-coded references to the directory pharo (as in the line). There is no directory pharo in the repository, and it doesn’t get created in install.sh. Should I be renaming the server-tools directory as pharo? Or should I be installing pharo inside the repository structure? tl;dr: What directory structure do your tools expect, and what do I have to create (vs what your scripts create)? Thanks! - Mark

Hi Mark, Something you may want to consider in the future is to use Docker. You can easily deploy Docker images with Pharo and you can also use `docker-machine` to create and manage your AWS EC2 instances. I recently wrote a blog post about that but with VA Smalltalk: https://dev.to/martinezpeck/deploying-vasmalltalk-on-amazon-aws-arm-servers-...

Yes, there was a small typo there: there is no ~/build directory, there is a ~/pharo directory, which gets created when you run the install.sh script.

Later, the deploy.sh script creates the ~/pharo-http-server directory where the example server/services runs from.
