2024-01-20 Petclinic fork https://github.com/xet7/pet , with command blink redbean.com
- With Petclinic website, it is possible to add pets, visits to clinic, etc. There is no login system, it is possible to add to database directly at website http://127.0.0.1:8000/ or http://YOUR-COMPUTER-IP-ADDRESS:8000/
- When xet7 added issue about blink segfault at s390x, 5 minutes later jart added fix https://github.com/jart/blink/issues/162
- Blink is x86_86 emulator, similar to qemu https://github.com/jart/blink . With blink, it works at Linux s390x. Without blink, it works at x86_86/arm64 Win/Mac/Linux/BSD, but ASAN security feature does not work yet at arm64, like mentioned at Makefile of https://github.com/xet7/pet . If there is errors, maybe you need to run it with
chmod +x redbean.com && sh -c ./redbean.com, or also need to installapefrom https://github.com/jart/cosmopolitan . - Redbean is webserver https://redbean.dev
- Fullmoon is Lua web framework https://github.com/pkulchenko/fullmoon . Petclinic has fork of Fullmoon, making possible to use SQLite across CGI-like Lua processes of Redbean, like mentioned at Readme https://github.com/xet7/pet
- SQLite has triggers, and it's possible to Redbean's cron like scheduled actions
- By using Makefile with
make allormake startit makes one executeable. When starting, it creates SQLite database to same directory, adding data, withsrv/.lua/*.sql - At fork https://github.com/xet7/pet , xet7 added all external
.sql, Javascript and CSS dependencies directly inside executeable. This can be seen at Makefile, where files fromsrvdirectory are are added to.zipfile, that is added to end ofredbean.comexecuteable. - Releases at https://github.com/xet7/pet/releases
At Makefile, xet7 fixed make benchmark of wrk benchmarks to to work at Mac M1 brew install wrk and Linux sudo apt install wrk . But wrk does not yet work at s390x, xet7 added issue about it to https://github.com/jart/blink/issues/163 . If you start with silent mode ./redbean.com -s , then at M1 Air macOS Sonoma is this benchmark:
~/Downloads/pet$ make benchmark
wrk -H 'Accept-Encoding: gzip' -t 12 -c 120 http://127.0.0.1:8000/

- It is possible to show hidden files like
.gitignorewith Lua IDE, ZeroBrane Studio, this way, and also debug redbean: https://github.com/xet7/pet/wiki/Redbean
- Unrelated to Lua, there is also QuickJS (similar like Node.js/Bun/Deno), where it is possible to embed Javascript to same Cosmopolitan x86_85/arm64 Win/Mac/Linux/BSD executeable binary https://github.com/xet7/pet/wiki/QuickJS
- Works:
- TSC platform game, C++ https://secretchronicles.org/en/news/2020/11/16/tsc-for-s390x-available/
- Darkest Hour halloween text adventure game, C89, xet7 ported to 30+ CPU/OS https://github.com/xet7/darkesthour
- V https://github.com/vlang/v/issues/18737 at 2025-04-03 now works!
- Zig https://github.com/tigerbeetle/tigerbeetle/blob/main/docs/internals/HACKING.md#building
- Does not work yet:
- Bun https://github.com/oven-sh/bun/issues/2632
- Partially related, Zig works, see above https://github.com/wekan/ferretdb/tree/main/node-deno-bun#trying-to-compile-llvm-for-zig-and-bun-at-s390x-fails
- Deno, because Rust ring (a crypto dependency) does not support s390x https://github.com/denoland/deno/issues/20212
- Bun https://github.com/oven-sh/bun/issues/2632
Ported by others, not xet7:
xet7, as maintainer of WeKan, got access to mainframe at IBM LinuxOne Community Cloud. Access to those servers is monitored, it's running on a real mainframe.
Previously xet7 had ssh access. At 2023-09 xet7 got web console access, and IBM bumped quota to 2 VMs with 8 GB of memory, 200 GB disk and 4 CPUs each. At web console it is possible to create and remove VMs, and select distro like RHEL/SUSE/Ubuntu. xet7 did do-release-upgrade to upgrade newest Ubuntu 23.10.
- wekan-VERSION-s390x.zip at https://releases.wekan.team/s390x/
This Snap package https://snapcraft.io/juju-db , created by Canonical, has MongoDB for various CPU architectures . It is internal package for Canonical's Juju service https://jaas.ai . Snap repo at https://github.com/juju/juju-db-snap and copy at https://github.com/wekan/mongodb-snap
Install Snap for your distro https://snapcraft.io/docs/installing-snapd
Then:
ssh yourserver
sudo dnf install nano
sudo reboot
sudo snap install juju-db
sudo snap refresh juju-db --channel=5.3/stable
sudo snap enable juju-db
sudo snap start juju-db
nano .bashrc
There add path to commands mongo, mongodump, mongorestore etc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/snap/juju-db/139/usr/lib/s390x-linux-gnu
export PATH="$PATH:/snap/juju-db/139/bin"
Save and exit: Ctrl-o Enter Ctrl-x
Exit ssh, and ssh to server again,
exit
ssh yourserver
Or alternatively just read new paths to mongo etc commands:
source .bashrc
Now MongoDB is at localhost port 27017. You connect to CLI with command:
mongo
New info 2022-01-18:
-
Install snapd https://snapcraft.io/docs/installing-snap-on-red-hat
-
Reboot
-
Install MongoDB, so it will be at port 27017:
sudo snap install mongo36-configurable
- Install WeKan s390x bundle from:
Old info:
sudo yum -y update
sudo yum -y install git nano npm curl wget podman-docker openssl-devel libcurl-devel clang zip unzip
docker run --name wekan-db -d -p 127.0.0.1:27017:27017 mongo
sudo npm -g install n
sudo n 12.18.0 ## newest 12.x from https://nodejs.org
mkdir repos
cd repos
git clone https://github.com/wekan/wekan
cp wekan/start-wekan.sh .
nano start-wekan.sh
# Edit start-wekan.sh for ports and paths, so starts
# "node main.js" at "build" directory".
# Look for version number from https://releases.wekan.team/s390x/
wget https://releases.wekan.team/s390x/wekan-VERSION-s390x.zip
unzip wekan*s390x.zip
./start-wekan.sh
Node.js LTS newest 12.x release for s390x can be downloaded from https://nodejs.org
MongoDB v4.x Community Server for s390x RHEL7 is at https://www.mongodb.com. For example files can be like these filenames:
- mongodb-org-mongos-4.2.3-1.el7.s390x.rpm
- mongodb-org-server-4.2.3-1.el7.s390x.rpm
- mongodb-org-shell-4.2.3-1.el7.s390x.rpm
- mongodb-org-tools-4.2.3-1.el7.s390x.rpm
Installing is similar like at Raspberry Pi
You can start it with start-wekan.sh from https://github.com/wekan/wekan or add SystemD service.
Setup ROOT_URL like described at Settings
At wiki is also info about Caddy/Nginx/Apache etc.
Some related links also at Platforms
- Install Node.js
- scp wekan-VERSION.zip bundle to s390x server, and unzip it
