Software collection rh-php73 amv7
by mark 29 Jan '21

29 Jan '21

Hello, Over the past time received an increasing amount of request for the rh-php73 Software Collection on armv7. Mainly to be able to run nextcloud but also zabbix 5.0 requires php7x. For full disclosure: the request come from the Nethserver community, which provides a all-in-one smb server based on CentOS x86_64. And the arm port of this is a small scale community effort. This being out of the way, I have rebuild the bare minimum rh-hph73 packages to install nextcloud without issues.(1) Just pushed the source packages through mock to rebuild them for armv7, first tests are encouraging. So far so good, problem is my build system is me and my keyboard. Which is not a very sustainable way to maintain rh-php73 for armv7. See a lot of nice hardware posted to the list, to be frank a bit above the budget I'm willing to put in this community effort. Are there other people on this list who want to join the effort to provide an unofficial community driven armv7 port of rh-hph7x? Or is this even on the white-board at the CentOS altarch sig? Until now did not find a public build-system for armv7 el7 does this exist? Any suggestions are welcome. 1) development repository with first results: __Note__ this is development do not use it in a real life application! https://vps01.havak.nl/nethserver/7/devel/

Desktop Boards

Hi, Most unfortunately, my MP30-AR1 board seems to have expired today. It gets stuck in an infinite boot loop: Boot from SPI-NOR American Megatrends Boot firmware (Project MP30-AR1, BIOS Ver F01; built at 15:11:23 on Sep 5 2016) Slimpro FW Ver: 2.4 iPP Ver: 01.15.01.00 Checkpoint 2D Checkpoint 2D Checkpoint 2D Checkpoint 2D So I'm looking for a replacement. Unfortunately, everything I can get in *TX form factor seems to be nowhere nearly as good, despite 6-7 years of advancement, and I can't seem to find a replacement MP30-AR1 board listed anywhere. I am aware of these: https://www.chip1stop.com/USA/en/product/detail?partId=SOCI-0000003&mpn=SC0… Pros: - Can just buy one Cons: - Poor performance despite lots of cores, especially single-thread performance compared to the old MP30-AR1 - Only half the RAM capacity at 64GB https://e.huawei.com/en/products/servers/kunpeng/kunpeng-desktop-board Pros: - Might have half decent single thread performance matching or exceeding the old MP30-AR1 Cons: - Questionable availability, unknown pricing - Only half the RAM capacity at 64GB Is there another offering that I'm missing? I know Gigabyte do a server system, but I need something reasonably quiet and compact rather than something rack mounted making data centre grade noise. Any suggestions gratefully received. Gordan

Supported Hardware for CentOS8
by Andreas Reschke 17 Dec '20

17 Dec '20

Hello together, I've running a SOHO mailserver (postfix, dovecot, amavis, spamassassin, apache, nextcloud, mariadb) with fedora on a Odroid-XU4 for a long time. Since limmited RAM (2GB) OOM kills amavis 2/3 a day. Now I'm thing to replace Odroid-HC1 with a SOC with more RAM Is there any Hardware (SOC, no expensive Serverbords) that runs with CentOS8 and/or Fedora? OS : CentOS8 and/or Fedora aarch64 CPU: min 4 RAM: min 4 GB Storage: eMMC with SSD, USB3 Thoose boards on https://fedoraproject.org/wiki/Architectures/ARM are all armv7hl (=32Bit) and on https://wiki.centos.org/SpecialInterestGroup/AltArch/AArch64 are all expensive Serverbords. Greetings Andreas

(Unofficial) epel for armv7hl offline ?
by mark 12 Dec '20

12 Dec '20

Hello list, today I'v got a : Forbidden You don't have permission to access /repodir/epel-pass-1/ on this server. While accessing https://armv7.dev.centos.org/repodir/epel-pass-1/ Hence it is impossible to make (grateful) use of the unofficial epel for armv7hl rebuild. Any Ideas / status updates on this?

Wrt Fedora boot, if usb works after you boot from the SD card, then I guess I'd check 3 things, rpi-eeprom (needs to be rather new to support booting from usb), rpi-firwmare (rpi-specific files in /boot, also need to be rather new), and maybe, but less likely, driver missing in the initramfs.

I don’t have the answer to your question. Instead I would suggest using podman (similar to docker) to run django, SQLite, etc in containers or pods. Thereby isolating those environments from your base os. But still be able to access by ip/port. An example showing how to accomplish can be found here: https://developers.redhat.com/blog/2019/09/11/develop-with-django-2-and-pyt… Best regards.

Hi everyone! I just joined the list. Total arm/rpi4 beginner here. Been using Fedora for a year on my personal computer (switched from Apple). Thats my background. My goal is to have my rpi4 run a webserver for my Django projects. I have been experimenting with Raspberry Pi OS, Fedora 33 and Centos 7/8 on the Raspberry. I would like to use a yum/dnf based distribution on the Pi, because I am a bit more familiar with its cli. I believe that the CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw image would be the way to go. But frankly I am terrified by configuring all the different sources for the latest packages (sqlite3, django 3, and so on) and getting them to interact flawlessly without breaking the system. Fedora does not have a native rpi4 image. They are generic and boot differently that the CentOS one. Can I use the boot partition from CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw combined with the Fedora Userland? Id have to disable kernel updates I guess and cross compile them myself (done that successfully yesterday). TLDR: My question is: How do I get the native rpi4 centos way to boot combined with fedora userland? Jay
