About s390x

Petclinic s390x

2024-01-20 Petclinic fork https://github.com/xet7/pet , with command blink redbean.com

Petclinic Benchmark

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

Lua IDE

QuickJS

  • 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

Other non-WeKan Open Source projects xet7 tried to build at s390x

Ported by others, not xet7:

From xet7, WeKan at s390x

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.

Installing MongoDB for 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

RHEL 8

New info 2022-01-18:

  1. Install snapd https://snapcraft.io/docs/installing-snap-on-red-hat

  2. Reboot

  3. Install MongoDB, so it will be at port 27017:

sudo snap install mongo36-configurable
  1. 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

RHEL 7

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

Setup ROOT_URL like described at Settings

At wiki is also info about Caddy/Nginx/Apache etc.

How this s390x bundle package was created for RHEL 7

  1. Install Node.js
  2. scp wekan-VERSION.zip bundle to s390x server, and unzip it
  3. Clone and build Fibers, copy fibers to bundle, and zip bundle.
git clone https://github.com/laverdet/node-fibers
cd node-fibers
node build.js
cd ..
cp -pR /home/linux1/node-fibers/bin/linux-s390x-72-glibc bundle/programs/server/node_modules/fibers/bin/
zip -r wekan-VERSION-s390x.zip bundle
